@@johanlundberg8449 and is it coincidence that Nvidia have a raytracing card out and AMD does not?

IBM lost a huge long term business partner and by the looks of it AMDs next gen GPU is now delayed until next year when the Nvidia 3k series is about to be released (maybe they will both hold back now)

[@joeyvdm1]

@@Nossieuk I am not so sure about RDNA2 being delayed, AMD and Lisa Su herself have stated multiple times and right up till recently that both Zen3 and RDNA2 are still 100% confirmed for this year. There have been many rumors going around about delays, but AMD and Lisa Su have shot them down repeatedly. AMD do keep stating that RDNA2 is releasing before the next gen consoles and so is Zen3. So I do think they will release this year still, unless AMD and Lisa Su make an official announcement saying otherwise, I wouldn't believe any other information. There have just been too many rumors about delays that keep getting debunked by AMD and Lisa Su, so I am just not believing anymore new rumors about delays. I will believe official word on the matter from AMD though.

Yeah, but Apple.. Apple Computers used IBM PowerPC RISC CPUs in their MACs, then they wokeup to reality and switched to Intel X86 CISCs for ultimate capablities.. But behold, they've recently become stupid again and now they have dumped CISC to go back RISC CPUs using custom ARMs.. The good thing though is that Apple users really can't complain now when PC users refer to them as consolers.. Hah

@@Locutus people have to know the history of DOS to get that, I think. IBM rushed to get PCs out, initially as a "loss-leader" to get businesses into "real" hardware. They never imagined Microsoft would license to companies like Compaq. I guess IBM was looking at DEC's terminals for a business model. Bad move. Apple deserves credit for popularizing the idea that individuals should own/be in charge of their own computers. Commodore64s were too underpowered, and Amiga too late. Being older, I know history of "home" computers (now nearly all called PCs). Funny how many parallels there were in 21st century consoles. I imagine the same is true for smartphones.

[@IrishCarney]

I remember when I was an Apple true believer arguing against Intel fans, advocating for the superior performance of PowerPC RISC chips even though they had lower clock speeds than Intel Pentiums. "Wintel" (Windows and Intel combined) were the enemy. Then not only did Apple leave PowerPC for archenemy Intel, Microsoft left Intel for PowerPC. Boy was I thrown for a loop.

[@joemann7971]

Well, Microsoft only left Intel on the console side. They obviously still work with Intel. lol But yeah, I also had a friend that said the same thing about Apple. But at the time, the statement was also true about AMD processors being fastest than Intel despite their CPUs being faster. Intel was heading downstream fast, but it was their mobile division that developed the core duo that saved them. I think that was also around the time that Apple went with Intel. The Core Duo is what put them back in the map.

10:19 - you probably meant to say "AMD", not "ATI" :) Also, according to an interview with Nicholas Baker, the lead architect behind Xbox 360, one of the biggest reasons Microsoft chose PowerPC over x86 by Intel or AMD was because his team figured out that CPU clock speed isn't going to get much higher (especially when you take into account that power consumption and heat dissipation play a very large role in the design of a game console) and that the solution for increased performance in the long run is parallel execution. In other words - a multicore CPU. Problem was that neither Intel or AMD had anything like that on their roadmaps (at least at the time) while IBM did, so Microsoft chose to partner up with IBM. EDIT: For those interested in more details, here's the full interview with Nick Baker: kzbin.info/www/bejne/gIGchXeCrdaSZ7c Oh, and thanks for all the thumbs up :)

[@amirpourghoureiyan1637]

Amazingly accurate considering that we've barely increased clock speed since the mid 2000s. Multicore's become the focus of new chips, even though Intel got to 5ghz on their processors recently, with the 9900K coming out over a year ago. AMD's managed to take IBM's place in consoles, being involved in every system for most of the 2010s until the Switch came out.

[@TheMarc1k1]

Thanks for the info! Very interesting, 5GHz is a pretty much a hard wall for PC users to push past in most cases or at the very least requires a lot of money spent on either the CPU or it cooling it... hell both really, so expecting consoles to ever reach that level comfortably is still unrealistic, let alone back in the mid 2000's - it's actually pretty cool that they had the foresight to recognise this, I believe there's some 'law' quoted about this very subject though isn't there?

[@alexandernorman5337]

@A World Under A Spell We'll have to agree to disagree on everything you just said. I'm not even sure how you are coming up with your games list. But I did some PC gaming as well as console gaming. None of the consoles could match running a PC with Voodoo 2 in Glide. But the N64 came somewhat close. The textures were laid out right, the animations were good for its time, the lighting was appropriate. The edge antialiasing it used wasn't as good as the FSAA that came later (post 2000), but I doubt the difference between the two would even have been noticeable with the N64 because of its intrinsic blurriness. It was like a low textured version of a PC. The PS looked absolutely horrendous in comparison. The textures strangely contorted because it couldn't correct for perspective. And pixels shimmered, and polygons popped in and out because it lacked a Z buffer. It rendered artifacts galore. And its lighting ability was lackluster. Even at the time I knew it couldn't really do 3D. I'll agree with you that the audio quality on the N64 wasn't good. But the N64 sounded better than the PS looked. The PS had the better controller, I'll give it that. All the consoles of that generation were a tradeoff to meet the transistor budget. The N64 had a small texture cache size because that's all they could fit after implementing the rest of the hardware. The PS lacked a Z-buffer and a proper texture wrapper because of the same reasons. And the Jaguar didn't even have a texture wrapper. But they were all tradeoffs of the best engineering solutions available at the time.

Also, I seem to recall some malicious code being inserted into Intel firmware and software that crippled some AMD products intentionally. Something AMD has never resorted to.

[@EphyMusicOfficial]

Let's not forget that by putting the pins on the CPU, you also lower manufacturing costs for the motherboard. There's also no such thing as "mounting pressure" in that case, as pins don't need to be pushed against something vertically. Instead, they're clamped and contact is made laterally.

It actually wasn't anything "special", it was just a Dual 2.0GHz PowerMac G5 since that was the chip they used stock at the time. I left a comment somewhere on this thread, but I had purchased that exact computer before going to E3 the year the 360 was playable (and the PS3/"Revolution" Unveiled). Every single demo station had an empty shell of the launch 360 right next to the exact computer I bought. I had to ask a few of the demo drivers before someone with the right knowledge was able to answer (I think it was someone from Lionhead who was showing off a Fable tech demo). They told me they had a few of these at the studio and other than specific specs on each unit (which were the stock "build to order" G5s from Apple's site), it was indeed just a mostly off-the-shelf PowerMac running the SDK. Pretty cool stuff. It was so fun getting back home, looking at my tower and thinking "huh...I bought this thing for music/video production, but actually have an Xbox 360 DevKit, too" :)

[@megan_alnico]

I'm pretty sure the CPU in the Classic Xbox was a Pentium III "tualatin" and not a Celeron. It gets murky because at that time because traditionaly the difference between the Pentium and Celeron was chache size, with the Celeron being made from Pentium III chips that had quality issues. This version had the same cache size. Also Intel was being embarrassed big time because this generation of overclockers discovered that Celerons could out perform PIIIs. Basically cache speed was more important than cache size. PIIIs had twice the cache at half the speed of the Celeron but preformed worse. I believe this is why the tualatin version of these chips were so similar. Anyway, like many generations of Intel chips at the time the LAST generation of chips outperformed the first generation of the NEW chips. I believe this had something to do with the quality of chip yelds always staring off poorly. That tualatin and even the mobile version were able to reach P4 performance levels with the right overclock. It was some dark times for Intel. Unfortunately Microsoft ran it CPU at 733mhz and not at the chips 1.4ghz max speed. My guess is, once again, yealds. Much more of the chips would run stable and cool at 733 then at 1.4 and it was cheaper. All this to say that by the time they were developing the 360, all Intel had was the P4. Everything else was basically the same PIII chip Microsoft had already used. The P4 was such an engineering failure that the 'Core' lines were based on a modified PIII core and the P4 'nerburst' architecture was brushed under the rug. This is mostly from memory so I may have missed a few things. I had an AMD Athalon XP at the time and really enjoyed my gaming experience. Edit: Thanks to everyone in the comments for their feedback. It turns out the Tualatin CPU was the fasted you could swap into the original Xbox. Not the stock CPU. It's still a PIII and not a Celeron. It's been almost 20 years now and I was bound to be a little wrong. You all are great.

@@comicsans1689 Fairly much so I'd say, and even though Apple announced here in 2020 that by 2022 everything will be ARM, I'm fairly sure that choice was made back around 2016-2017 as Intel was the main name in x86-64 (aka: x64) CPU's at the time and AMD had get to start laying down the smackdown with the Zen architecture (they were just coming off the relative flop that was AM3/+ with their high heat-output, poor IPC and pseudo-multicore design (sharing key FPU's and such between what was otherwise pairs of true cores), which powers XB1/PS4) when Apple saw the problems Intel was having and was going to keep having at the time, so gave themselves about 5 years headstart to start moving MacOS from x86 to ARM to have it ready for their 2022 launch. If Apple waited for say 2018/2019 to make the move from Intel for MacOS, they might have chosen to go with AMD for Zen-family CPU's to power future Macs, or they might have still made the choice to go with ARM and move from x86 anyway. We don't really know.

[@romannasuti25]

Yeah, and funnily enough, Power arch hasn’t been good for general compute efficiency since G4. They’re still useful, but mainly for enterprise server workloads as I/O, reliability/live failover, and security are greater concerns there (and Intel has been dropping the ball on those, leaving an enterprise server niche). There’s reason to believe IBM’s s390x and Power arch’s have been drifting into each other with s390x maxing out reliability and Power being more balanced. Right now, the best are: Dedicated HPC: Fujitsu weirdly enough, using their newfangled ARM A64FX chips which are absolute vector compute demons, basically the modern-day Cell except not a nightmare to program General-purpose/commodity: AMD because Zen2 arch is hard to go wrong with Enterprise workloads: IBM, Power for better cost/performance or s390x for absolute maximum reliability

[@s1mph0ny]

That's a true statement, but when you compare to the time era it doesn't mean much. AMD wasn't able to push 3ghz clocks on multi-core processors without using even more heat, and Intel wouldn't have anything heat/power competitive until 2006. If things had waited just a year it's easy to see how different this generation might have been though. Apple likely had advanced knowledge of how much better the core2 was compared to outgoing P4's, and they would have delayed their move from G5 to intel to match with this vast improvement. OTOH, Sony pushed back their ps3 launch due to blu-ray AACS fuckery, and if they had known the ps3 was going to be so far delayed, they could have used that time to gain a huge compatibility and performance advantage by leveraging a core2 based processor on their platform. Given how far below competitive clocks the wii, u, and switch have been I doubt very much that their choice of platform matters in terms of having a good thermal performance. They just need to ensure they meet the bare minimum cooling requirements spec'd by the chip and hope that their supplier isn't lying about thermal/power properties.

It wasn't until the Northwood core in 2003 that HT was introduced on consumer Intel CPUs with the 3.06GHz Pentium 4 w/HT. Later a Pentium 4 3.0GHz HT was released with the higher 800MHz FSB (whereas the 3.06GHz was based on a 533MHz FSB).

The part about the Pentium 4 is wrong. The Pentium 4 only supported RDRAM on launch in 2001 with the Willamette architecture. The Northwood architecture that was introduced in 2002 already switched to DDR SDRAM (or what you incorrectly label as regular DRAM since there are multiple variants). The P4 HT processors were introduced in 2002 with the Northwood architecture. (3.06Ghz in 2002 and 3.0Ghz in 2003 with a faster FBS) and did not support RDRAM.

[@KonjonoAwesome]

Not only that, but Northwood was pretty tame temperature-wise through the 2.8 GHz models. Pushing past that frequency and switching to 90 nm with Prescott is where the heat issues really began. Netburst wasn't an ideal architecture for IPC but the Northwood chips were competitive with AMD's offerings at the time. Both consumed about the same power. I'm guessing power consumption and price per unit were a larger concern than thermals or performance in Microsoft's decision to move on from Intel. Microsoft must have sunk outrageous amounts of money into redeveloping their SDK for PPC. You would think they would have stuck with x86 if the price had been right, based on what x86 hardware was available at the time.

[@yukinagato1573]

Pentium 4 Willamette chips were first released supporting RDRAM only (socket 423). Later on, before the Northwood release, Intel launched Willamette cores (Pentium 4 and the first NetBurst Celerons) supporting regular SDRAM (socket 478). With the Northwood core, DDR became the standard.

[@jrus690]

No is was not the Pentium 4 that did not support DDR SDRAM or SDRAM, the north bridge was separate entity from the CPU up until the Core 9xx series chips. Intel bet the farm on RDRAM and decided not to make a chipset for DDR SDRAM until 2002. They even designed a Pentium pro (P6) chipset with RDRAM because they thought that was the future but those chips never had DDR FSB so they could not use it, except in dual processor servers that is. In 2002 Intel gave up on RDRAM and chucked all the support and chipsets for it.

Later found out around some brazilian forum talking about the capacitors and changing them to fix the issue. I tried it and never again had more YLOD issue.

About 8 months after the initial launch of the first Pentium 4 processors, new budget motherboards with a new chipset were released that utilized the much cheaper (but slower) PC133 SDRAM, followed about 6 months after that by another chipset and set of motherboards that replaced those that used DDR RAM, which Intel stuck with moving forward, joining the rest of the industry.

Heat wasn't the only issue with IBM+Toshiba's Cell architecture. The largest problem point for these consoles, was that they released very early during the era of moving to lead-free solder, and in those early days, the mix of metals in the solder weren't fully figured out yet, and the techniques and tempuratures that you have to use for lead-free solder were just different enough that things were bound to go wrong in the right conditions. And in these consoles, right conditions they were. Early failures were mostly due to cracking of brittle joints, that couldn't deal with the flexes and thermal differences between the base PCB and the CPU substrate PCB. But later on, the consoles that had come out of that era without issue had issues with the tin slowly starting to fringe outwards, eventually, the little hair-like leads coming off of them bridging with other joints, shorting the connections and interrupting the data processing flow or voltages, depending on what got shorted. If the consoles had released in the era of leaded solder, where the techniques and manufacturing process had already been in use with little failure for decades, this would likely have never been an issue, as there would not have been any stringing solder, or brittle joints, and the heat load would have been much less of a problem. Even now, leaded solder, while generally being seen as less environmentally friendly for some reason (likely more related to the eWaste industry than just having it in a computer), still proves easier to handle and generally better for getting a good, strong and reliable joint, although manufacturing and design has long since shifted to account for the potential issues that tin based solder brings to the table.

@@bizzzzzzle The Cell architecture is co-developed between IBM, Toshiba, and Sony. In the full version of the Cell architecture, the version that the PlayStation 3 had/has, there was one PowerPC core with a few instructions tacked in to handle Cell specific workloads, that served as the master core, and several slave cores that ran on an offshoot instruction set that wasn't PowerPC compliant. The Master core served to handle all of the IO, the base processing power for the game, as well as the scheduling of the slave cores, while one of the slave cores got used for system UI, and the rest were reserved purely for games to use. The XBox 360 did get the Cell architecture, but it got aodified version of it. Instead of one master and several slave cores, the XBox 360 recieved a version that had repurposed the core communications instructions of the main PowerPC core to communicate with other full PowerPC cores, and there were three of these full cores, in what is now a much more traditional multi-core configuration, that would have likely never happened, if not for the core communications instructions that were co-developed by IBM, Sony, and Toshiba. Imagine a single core XBox 360. What a different world *that* would be.

@@robertvuitton While a new CELL style master-slave core processor using POWER10 and a newer manufacturing node would be great, I don't think it would have as much "Unlockable potential" as the original CELL did. The difference between then, mid PS4 cycle, and now, is: Back then, single-socket multi-core processing was still a very, very new thing, and not many people knew how to code for it properly. In the mid cycle of the PS4, most developers didn't properly utilize the eight jaguar cores of the consoles of that generation, because of AMD's whole thing about having combined important sections of their cores, leaving four floating point units and eight integer units, in practice working out as a strange hardware hyper-threading, and on the Intel side, we were still in the middle of the quad core monopoly era. Now, The Quad core monopoly era is completely and entirely over, and most decent developers practically fully understand how to work with six to eight cores in practice. As long as they can understand both the master and slave architectures, have a relative understanding of how the master core schedules the slaves, and actually make sure to code their program to take advantage of the fact that the hardware is there, then I don't imagine it posing the same intimidating threat that it did back then. On top of that, Cross communicating master cores have come a long, long way since then, and Intel's Ring Bus has proven particularly impressive for its theoretical limitations, with AMD's shared cache mesh bus, the "infinity Fabric", proving to be an absolutely incredible work, although its ties to system RAM clock hold it back a bit unfortunately. While cross communicating master cores still poses some theoretical limits, it seems to generally have more flexibility in terms of how well it scales depending on its implementation, and can be implemented in a larger variety of ways. in short, I think that we've finally reached the era where what made the CELL hard to code for yet such a wonder of unlockable performance is long over, and a new version with updated manufacturing and architecture wouldn't look nearly as impressive as it did back then.

For Gamecube they ditched the MIPS processor (used in the N64 and the PS1) and went with the impressively scalable PowerPC. Apparently one thing that impressed NIntendo was how easily M2 was able to have two CPUs work together with almost no overhead and no tricky programming compared to the Sega Saturn, 3DO people ended up working both at WebTV and on the original Xbox, so there were people familiar with the PPC and in dealing with IBM since they had already worked with them to create a low-cost PPC that was also tuned to be especially good for the needs of 3D games.

Red ring isn't caused by high temperatures and, in almost all cases, isn't related to the IBM CPU at all. The underfill used by AMD/NEC for the GPU was a poor match in terms of thermal expansion coefficient and glass transition temperature. After many thermal cycles it causes fatigue in the solder bumps attaching the silicon dies to the interposer. Doesn't matter how hot they run, it'll fail no matter what. It's also why reball/reflow is only a temporary fix. They're just going to crack again. This was resolved at some point during the Falcon revision of the 360 with a move to a different underfill material. Take a look at xenonlibrary and ripfelix for some good deep-dives.

The Race for a New Game Machine book was impressive. It said that the 360's PPE was originally designed for the PS3. IBM showed Microsoft the PPE, and Microsoft was impressed. Microsoft did add their own special sauce to that chip and extended the vector register file. It might had 2 vector units per core (6 threads, 6 vector units), which knocked down the advantage of the Cell CPU by a little. Around that time, even PCs were going multi-core, so the risk for these multi-core CPUs was relatively low. IBM also was a good choice because IBM developer documentation was actually pretty good at that time (it's been a while since I have seen IBM developer docs). Microsoft is a compiler maker, and the in-order nature of the CPUs might be able to be helped with compiler optimizations. That probably sounded really good to Microsoft. The other advantage was that to learn how to develop an Xbox 360 game, you just needed a multi-core PowerPC system with an ATI graphics card, and they had Apple Macs at the time. I also feel that the likes of Unreal Engine 3 taking off helped since Unreal Engine is still being used, and is often praised at the time as "that system will run UE3 games very well!" Considering their options, outside the RRoD, the CPU itself wasn't a bad choice. They probably should have tested the CPU more before releasing (they released an early version instead).

[@hugo-garcia]

Mistakes were made : 2:11 xbox had a pentium III cpu not a celeron

[@cyphaborg6598]

Actually the culprit of many problems with YLOD and RROD had nothing to do with IBM's chips, it was due to a flaw in a general flaw with gpu materials being used at that time.

[@italodirenzo5876]

I find it interesting to see the shift that hardware chips have taken over the years from excessive diversity to a rigid monoculture. Back in the day it seemed like every console and arcade machine had its own customized hardware designed specifically for it. But as games became more technically advanced and costs of making them increased, it just doesn't seem to be financially viable anymore for console manufacturers to spend the exhorbant amount of money on custom designs and instead reaching for tweaked off-the-shelf solutions. Which is why the PS4 and Xbox one run x86-64 (like standard PCs) and the Switch runs ARM (mobile phones/tablets). I feel like for the 360, the PPC deal with IBM was simply the most financially viable deal for them at the time. Look how much money Sony lost on engineering the Cell. Enough to offset pretty much all profit that would have been made from the PS3 in its lifetime. Despite how interesting of a design the Cell was, I don't we'll ever see such a radical and risque design like that ever again because it just isn't financially viable anymore.

[@mytech6779]

You have it a bit backwards, they made custom hardware because it was required for the games, commodity hardware was not capable. They never made custom hardware just for the fun of spending money.

[@tHeWasTeDYouTh]

2:47 the original plan for the Xbox was for the console to have 128MB of ram but Microsoft cheaped out last minute. It makes me mad even today. I always wondered why the original Xbox never got a CPU/GPU die shrink(180nm cpu and 150nm gpu) but I have never found any article from MS, developers or game media stating why this didn't happen. MVG do you know? Intel did shrink the Pentium 3 to 130nm and Nvidia had their GPUs made by TSMC so I am sure they could have moved the Xbox GPU to 130nm.

[@campkira]

[@jpesicka492]

Yes the sega chihiro is essentially an xbox with 128mb. You can upgrade it to 128mb or have someone do it for you for about $100. It basically allows you to play Sega Chihiro arcade games, no other real benefit considering Xbox games were designed and optimized to only you 64mb of memory. It does help with other emulation as well but ya, by now we have modded 360/ps3 or a PC that can emulate the higher end stuff.

There were a number of incorrect statements in this video but I'm only going to mention one. The original Xbox did not have a celeron processor. It actually had a modified Pentium III Coppermine processor (modified down to reduce cost but preserving the key aspects of coppermine).

Conclusion: Apple's philosophy about heat isn't changed after all these years

[@KyussTheWalkingWorm]

Considering how they shipped laptops with completely inadequate cooling for so many years, this "philosophy" only exists when it suits them.

[@jmtrad1906]

They shipped the last macbook with passive cooling (there is a fan, but is not connected to the processor) just to make comparations when their arm is released.

[@Fadexpl]

It's gonna change with ARM though.

[@Yeen125]

Apple’s obsession with heat (or having a lack thereof) goes back to the near beginning of the company’s founding, as Steve Jobs hated cooling fans and insistent on using passive cooling whenever possible.

[@Otto_von_Chesterfield]

@@jmtrad1906 I saw a video from Linus that barely saw any performance gain even if you totally remove the thermal limitation. Not to mention most people probably won't 100% saturate the CPU of a macbook air for hours on end, it's just not what you would buy for that given use case I would think.

[@Z3r0BYT3]

At 4:25 in the video you talk about the Pentium 4 clocked at 3 GHz and has a 200 MHz physical clock. What is meant by the physical clock in this case? I'm having a hard time finding information or figuring out what to search on to learn more about the differences?

[@mitchel71]

I still remember all the red rings my friends got. I had a ps3, but I remember a couple of my friends had Frankenstein machines, holes cut in the side, fans hot glued in to suck the heat out, one guy had it straight mounted to piece of wood instead of in a case at all Strange times to be sure.

[@mitchel71]

I played the crap out of my ps3, never had any yellow lights. I know they were out there, I'm not naive, but I think the failure rates were 10% of the 360s.

[@damonsalvatore3222]

I kept the shell off of mine and would just take the top of the disc drive off, remove the magnet then insert the disc & put the drive lid back on . Basically hotswapping which would also allow for ISO mods on unmodded 360s :)

[@techtomek5062]

The funny thing is that while the consoles were moving to PowerPC, Apple turned their backs on IBM PowerPC and used X86. Now we havesimilar times again. Apple goes to ARM, Nintendo also uses. PS and MS use AMD APUs. The question is not which CPU architecture is used but which graphics acceleration. AMD has made a really great purchase with the ATi. The current success is based on this purchase. Intel can't get GPUs right we already saw with i740, Larabee we still wait for it 😄 We now need to see how ARM will evolve and if Apple is really getting performance out of ARM. But more important is the GPU performance and if there will be more competition from maybe NEC.

[@net_news]

Well, Apple moving to Intel was a huge loss for PowerPC, I'm sure Microsoft and Sony got a great deal on their PPC chips... becasue you need customers to keep your fabs working you know.

[@net_news]

@referral madness NEC PC98 series were x86 IBM PCs clones with a different BIOS... not a big deal. PC88 were really interesting though.

[@techtomek5062]

​@referral madness NEC or PowerVR is still active in the mobile sector. We have the successors of the Kyro graphics cards, for example the PowerVR GE8320 . In the Playstation Vita was also PowerVR built in

[@tHeWasTeDYouTh]

NEC has nothing to do with PowerVR, they left them in 1999. Imagination jumped with STMicro only for them to bail on them and have the Kyro 3 cancelled in 2002. It hurts even today when I think of it. I know Apples custom GPU uses Imagination patents but I don't know much more than that.

2:43 Why did software APIs have to change for a different CPU architecture?

[@Josh.Davidson]

Quick correction here, the red ring of death was not at all related to heat. It was a defective graphics chip from ATi. Replacing this chip with a newer fixed chip repaired the console. Heat caused louder fans and such, but didn't cause RROD. Also, by the time the Pentium 4 HT was released, Intel had long abandoned RDRAM in favor of traditional DDR.

[@mattiaswennerstrom6271]

Only the VERY early Pentium 4 used RDRAM and that one never reached above 2.0ghz and never had HT.

[@GraveUypo]

pretty sure there were pentiums up to 3ghz that used rdram. but the OPTION to use ddr ram came after a year or so. it made the cpu much slower though. still worth it over the overpriced piece of shit that was rdram found an article: www.tomshardware.com/reviews/intel-ddr,403-4.html

[@DripDripDrip69]

Since the memory controller was in the northbridge not in the CPU like nowadays it was really a motherboard requirement.

I miss so much when each console manufacturer tried to use a completely different design. Today everything is the same. SO BORING.

[@charlesg5085]

I don't understand that. When you play the game you can not even tell what cpu architecture it is running on. I am more interested in the ability to load Linux or custom upgrade the hardware.

[@barrynevio4440]

Although they shared the same architecture, harnessing the power of those processors was difficult and different between all 3 consoles. Making a cross-platform game at that time was a nightmare. My 360 was cursed. Out of all the consoles I've ever owned, the 360 was the one I took apart the most which was always for repair. The 360 was a such a furnace that the cooler mounts would deform under the heat. When I finally perfected my cooler mods and had it running seamlessly, I accidentally flashed the wrong firmware onto the dvd drive and bricked it. When I found a cheap compatible replacement, I spilled an entire diet coke into the console as soon as I took the cover off. At that point I took it as a sign and shelved it.

@MVG ATi didn't exist in 2013, they were by that time fully incorporated into AMD who bought them in 2006. ATi as a brand was used on some products until late 2010. Regarding the CPU used in the Xbox, it was a Pentium III with half the cache, not a Celeron.

good thing i only used mid level chip back then.... core2duo also start heating up after few years of used..

[@JustWingingIt-s5f]

What’s really bad is that all they case designers for the 360 and the PS3 had to do was improve air flow and use more active cooler with better thermal paste. I’ve modded both console cases by simply adding cut outs to improve air intake and on the PS3 it dropped cpu temps by 8 degrees C. The 360 relied on basically trying to passively draw air across the heat sinks from 2 incredibly small bands of holes. Stand up the console? Block the bottom intake. Add on a HDD? Block the top intake. The 3rd and 4th bands of holes? Blocked by the presence of the motherboard itself. All I did was cut a huge hole in the case and stand off a sheet of plexi to protect the components and temps dropped dramatically for that system. Add in the 2 small fans, one on the old style cpu cooler to push air through it and one on the extended arm of the gpu cooler to push air down over it and it runs without having a single stutter in fps

[@BruceStephan]

I get tired of morons dragging PS3s into the problem Microsoft did with their POS 360s . They never bothered fixing the problem in the first place by using better thermal paste and make some minor adjustments with their fans . SONY never really had a problem until after a lot of heavy use over a long time with the PS3 . I never had any problems with my PS3 and I used it just as much as my 360 and still have no problems . The 360 issue with me is very different . I didn't buy one til the big lie was going around that Microsoft finally fixed it with the HALO3 Edition 360 . Mine lasted 3 weeks . Microsoft has always been last because they still sell 💩 to their customers .

[@purplefuku]

And now Apple’s jumping ship from Intel! (For good reasons, too...) It’s funny: AMD’s chips are soaring, Apple’s SoCs are going to be super exciting... and Intel is having die shrink trouble & similar thermal issues like the PowerPC line had... What a wild moment in time!
