[@klafbang]

It's easy to laugh at afterwards, but compilers are already extremely smart, and when first introduced, people doubted they would ever be as efficient as hand-written assembler, so it's not completely silly to put a lot of the code analysis in software instead of hardware.

[@rhekman]

@@klafbang That's a good point. I'm not an expert, but I was studying computer science in the late 90s and was paying attention to where R&D was going. Just a few years earlier many people thought RISC was going to take over everything (and it had in minicomputers with Alpha, Sparc, MIPS, etc.) Intel was mildly successful moving x86 up market with Pentium-Pro, and at the same time their ICC compiler was the best at generating fast x86 code, beating out Microsoft, Borland, gcc, etc. Pentium-Pro being a pipelined and superscalar design, they knew to invest in compiler technology. From that perspective, Intel made a bet that - 1. Next generation processor designs would need simplified instruction sets. 2. To maximize performance a RISC processor needs to maximize pipelining and speculative execution. 3. It would not make sense to make the execution core simplified just to make the instruction decoding and ordering more complicated in silicon. 4. We already have a world class compiler team. 5. We need to make a new architecture that Intel doesn't have to share. With that backdrop, Itanium didn't seem that far fetched. Amusingly enough, Transmeta's design for an x86 competitor was innovative not just for Dynamic Voltage & Frequency Scaling, but it was also a VLIW RISC design, and it had a patented code-morphing compiler built in to the firmware. Their tech, as well as AMD's micro-op decoding in Athlon and Opteron, proved that you COULD keep x86 and just implement a RISC-ified processor on the back end.

ERRATA: - Duron was not budget version of K6-III but Athlon - AVX512 was introduced in Rocket Lake. Alder Lake could use these instructions if E-cores were disabled but Intel blocked that feature with uCode updates

[@geekst0rm87]

38:00 The AMD Duron was the budget version of the Athlon, not the K6-III

[@williamcroson9102]

Came to say the same. When Intel had Slot 1 with the PIII, AMD came out with the Slot A Athlon. And the number one reason that Slot CPUs existed was because the L2 cache was relatively large and therefore off die(Probably to reduce costs/increase yields) and they therefore needed a larger PCB for that cache. We only went back to Socket PIIIs and Athlons when they were able to integrate the relatively large L2 cache on the same die as the CPU. When this happened, AMD released the Duron, a cache reduced Athlon.

[@vertigo2893]

Indeed. And it was a stellar overlocker. Remember running a Duron 600 at 900+ Mhz for years. Same was true for the p3 celerons of the time, even though they still sucked even when overclocked to the moon.

Bulldozer architecture did come good in its own way. When the games and other software learned to use the chip, it became a really good '8 core' option. I bought one when it first came out, an FX 8120, which had some problems until I paired it with a 9 series chipset. Then its parallelism improved markedly, and as the software matured, it performed increasingly well. I myself wrote code which used core affinity to make best use of the way Bulldozer/Piledriver worked, and had incredible efficiency compared to the same problems being tackled on comparable Intel machines without these enhancements built in. By the time I upgraded to a 8350, which comfortably overclocked to 4.8 GHz, paired with a decent GPU, performance was extremely good for the price point. In upgrading cycles I sold each CPU for a decent 75% of the original purchase price, upgraded from the 8350 to a Ryzen 5 5600, which my PC still runs. The laptop I'm writing this on is a Lenovo with an AMD Ryzen 5 5625U.

Excellent video! A wonderful trip down memory lane! One minor quibble that I noticed. At 38:04 you mention the AMD Duron as a budget version of the K6-3. The Duron was the budget version of the Athlon and was released June 2000. The original Athlon CPUs used Slot A from June 1999 to June 2000. The Duron was released when the Athlon was moved to the Socket A format starting in June of 2000 as there was no Slot A Duron.

Very nice Video. One Appendix: At the End of the AMD Bulldozer Era, AMD not only got a Deal with Sony and MS to sell them their APU's, but they remodelled the Bulldozer Cores: Every Core got it's own Insctruction unit. Those Puma, Puma+ and Kaveri Cores are the Cores which went into the Xbox and PS4, and you could buy those 4 Core APU for low power PC, with a compareable performance to an i3, without beeing a waffle Iron. AMD made never "Bigchip" Kaveri's. But the Kaveri's were the foundation for the ZEN. There are even (low performance) Kaveri for AM4. I still have A10-7850k and A10-7870k as low power Linux desktops running. CPU Power of an I3-4330 and an R7 250 GPU are not great but everything in one package makes some nice workstation.

[@macdudeguy]

I had a Kaveri as well that I ran 'CrossFire' with a R7 250 dGPU. The combo of it and the IGP did a pretty nice job. I remember having to seek out the 250 I found as being the one with more cores than the standard retail part, in spite of the name being identical. Good times...

[@camjohnson2004]

The Pentium Pro was a fantastic chip for what it was designed as, a Workstation CPU for CAD and various other tasks. it even ran Dual CPU better than Dual Intel Pentium CPU's, it was the CPU that the Pentium II was designed off, in fact, the Pentium II is technically a Pentium Pro, with a Die shrink and MMX Instructions with a re-designed cache system. You got the K3-III a bit wrong. K6-III was essentially a K6-II but instead of relying on the Motherboards slow Level 2 cache, AMD added 256K of Level 2 cache on the CPU Die, this would then relegate the motherboards L2 cache into a Level 3 victim cache. As for the Duron, this didn't come out until AFTER the Athlon processor. in fact it didn't come out until the 2nd iteration of the Athlon CPU that was Socket A or Socket 462. 2nd gen Athlon (using the Thunderbird core) had 256K of L2 cache on die, the Duron used the same Thunderbird core, but the L2 cache was reduced to 64K Itanium, what a joke of an architecture that was. but to be honest, the time intel shot them selves in the foot big time was the i820 platform, RDRAM, and the multi year licencing agreement they entered into with RAMBUS, this agreement crippled their ability to produce and support the Pentium 4 Processors with affordable and performant memory, it kept intel from using DDR SDRAM for many years.

[@movax20h]

Funny thing. Pat Galsinger (current CEO of intel) was a lead architect of 486, when he was about 27 years old. Also AMD 486, was not just a clone of Intel 486. It came pretty late, (just little before Pentium), but had some substantial improvements, including cache and power management, and better clocks. 386 was fundamentally the most important in terms of features. To this day we use similar model of the machine. 486 was huge jump to make cpu smarter (by any standard previous CPUs were rather primitive). And next one, Pentium, was a total rethink on another level, where it started becoming superscalar (up two two concurrent instructions), and Pentium Pro, as well Pentium II, become fully out of order with speculative execution, which is basically what we do to this day in high performance CPUs. (there were few workstation class CPUs before that were also doing it years before, and some mainframes doing it even before that). The UMC, you probably didn't see in real world, because they were mosly marketed in other parts of the world. In fact after their 486 clone, they lost patent lawsuit, and were prohibited from selling their CPUs in the USA. I think UMC Green CPU (486 clone), was from scratch design, with some reverse engineering of the chip too maybe. Cyrix 486 was another clean design, that was not based on Intel core. In fact it has a number of incompatibilities in a low level, which caused some operating systems to not handle it properly, or required special code to handle that CPU. But performance wise it was similar to Intel 486, and general architecture was very similar too.

I have to wonder if perhaps the way for x86 to survive would be for it to go the OpenGL route and be handled by something akin to the Khronos Group.

Fascinating little essay. I was born in 90, so my pc knowledge begins around the pentium 2 and taking apart ones that got thrown out. Growing up i always saw pentium 4 ads everywhere, so the first time i saw an athlon machine i thought it was junk.

It's crazy that opteron in 2010 had 16 cores compared to xeons 6 backthen, still didn't change the fact that they sucked but I think it's crazy.

[@TheDemocrab]

29:31 The ironic thing about people avoiding Cyrix for FPU is that I had the pictured chip (6x86-P150) and it lasted me long enough to get replaced by a 512k Athlon XP 2600+ clocked over 10x as fast. Even ran XP on that machine, albeit with significant RAM and storage upgrades. That included gaming, that Cyrix CPU was even able to manage Sims 1.

[@RetroBytesUK]

It was only stuff that leaned heavily on floating point struggled, plenty of games made little to no use of floating point and where just fine. Its just thanks to quakes approach to using floating point that Cyrix's reputation took such a kicking (and lots of people wanting to play quake).

[@twentyrothmans7308]

Thank you. AMD has really upped the game when it comes to processors. Bad business model - the ones I bought 10+ years ago are still running very nicely.

[@MrZics]

Not mentioned here: AMD has recently worked with ARM to make AI chips, while Intel has largely ignored ARM.

[@RetroBytesUK]

@@MrZics oddly at one point intel did make arm Chips, they bought the part of DEC responsible for the strong arm. The produced them still with the name strong arm, then under the name xscale.

[@RationalistRebel]

@@RetroBytesUK Indeed, I had a "Pocket PC" Windows phone with an xscale chip. It was...OK. What made them unbearable was cramming a Win9x era GUI into a small screen, requiring a mini stylus to do much of anything. Most of them still had a physical slide-out keyboard, a feature I still kinda miss even to this day. Alas, the iPhone's touch UI effectively eclipsed everything in the handheld space that came before.

[@cameronbosch1213]

Isn't Intel banking on RISC-V instead?

[@HedgehogY2K]

Didn't Intel have a Windows 7&8 compatible Broadwell CPU with 10 cores, the i7 6950x? I'd imagine that CPU would beat the Ryzen 2700x on average, though USB 3 is a bit problematic. It's easier for Windows 7 to be on an i7 6950x, and Windows 8.1 on an AM4 CPU with the B450 chipset. 8 supports USB 3 while 7 doesn't and last time I checked, most AM4 boards didn't have a lot of USB 2, only as an extra connector from the inside, which is what I'm gonna have to utilize to get 7 working on this Ryzen 2600E.

[@WishMakers]

This video makes so much more sense right near the end. I was growing up and understanding how computers work *just* as Intel took the lead definitively, so I was quite concerned about their recent fall from grace as it were. Turns out AMD's resurgence is more back to the Athlon status quo, with less mistakes this time, which is fascinating lmao

[@bbbl67]

Good history lesson. I was around for much of this history, watching it all. But I had forgotten some these things, and thanks for reminding me.

[@CraigieBee]

Great video. Missed a couple of things, one, you didn't mention Slot A vs Slot 1 rivalry... As that was around the time DEC were now working with AMD. I remember the DEC Alpha Slot A solution being used by DEC and AMD against the Intel Slot1 competitor. I do remember switching to AMD on the server side when the Alpha was no longer supported on Windows NT4 after Service Pack 3...lol But I guess that's more of a server focussed product...

Thanks, always enjoy watching your videos - real appointment viewing! My first PC build was an agonising choice between a Celeron and a K6-2. I went for the K6-2 in the end and had no regrets, an excellent processor for the money.

[@RetroBytesUK]

It really was a good CPU especially at that price point. I made the same decision as you too.

[@jasonnchuleft894]

To put into perspective how much brand recognition in the PC market had changed over time here's a small anecdote. I got my first PC back in 1996 after I've grown up with Amiga. At the time I knew what a PC was, I knew Intel and AMD and had a good understanding of how PC's work .. but I had never even heard of IBM.

amd's chiplet approach really helped them out. on zen 1 and zen 1+ (ryzen 1000 and 2000) desktop had a single die, workstations and servers had two or four active die that were nearly identical to the desktop counterparts providing a really easy method of scaling up to 32 cores. on zen2 with the io die + x chiplet count amd just went hog wild. i wouldn't be surprised if we get 512 core epyc cpus in the somewhat near future. also, zen4c is really cool. by limiting the voltage and clock speeds amd could shove 16 cores into a single ccx die and not have it melt under a full all core load. kinda want to see a budget ryzen cpu with those cores for the budget sff workstation market

[@hackerhomestead]

[@tomaszmarcinkowski8242]

Oh no, the Duron was NOT the budget K6, instead it was a budget Athlon! And before Duron, the K6 was the cheaper of two when Athlon was launched.

[@BrendanGeormer]

I hope it goes down in the history books what a massive turn AMD has had in the Ryzen era, going from "don't buy their products" to scrappy underdog, to peer level to now being undisputed best processors for most (consumer) use cases, while EPYC has been massive in the enterprise space as well; even if the marketshare hasn't caught up to adopting the new market landscape yet.

[@Penmaenmawr101]

Thanks, very enlightening, keep up the great work!

[@virtualinfinity6280]

Minor correction: The 286 never had a paged MMU. That was introduced with the 386. The 286 had segments, just like the 86, but with segments up to 1meg in size instead of 64k in the 86 and of course a 24bit memory space (16meg max) as opposed to 20bit (1meg max). The fact that the later 386 was a true 32bit CPU with a paged MMU gave it the - then common - nickname of "VAX on a Chip".

[@MayheM_72]

It's kinds funny. I'm a AMD guy, and a Nvidia guy. Not sure why. I built my 1st PC back in '09, and the last iteration before I packed it away in 2015 had a Phenom II x4 OC to 4GHz, and a 1GB Nvidia card (don't remember the #) that I was going to SLI.

[@mapesdhs597]

1GB... guessing perhaps an 8800 GT or maybe 9800 GT? Or maybe something later like the GTX 460? I SLI'd them all, ah the good old days. :D I had an AMD 6000+ system initially, but alas the mbd (ASUS) never received a BIOS update to support Ph2, so I jumped over to an i7 860.

[@MarkusE.]

P3 was first Slot 1 too, Duron was the budget version of the Thunderbird Socket A not of the K6-III

[@alexandermcalpine]

Fantastic video!

[@TrueThanny]

12:30 That seems to be an odd thing to say, given that Intel did not provide AMD the designs of the 386, in breach of their contract. AMD had to reverse-engineer the processor to make their own versions, and wasn't able to sell any until 1991, after a legal battle that Intel lost.

[@dolphhandcreme]

The K5 was basically a 29000 with a translation layer added. Worked quite well. After that, AMD bought Nexgen and used their design to build the K6.
