Bad caps on the Asus board: Thanks to all for giving me the hint of some bad caps on the mainboard. I will replace them of course! And I am very happy that you all are watching my videos so in detail that you are recognizing that. 👍🏻 You are a great community! Love all your comments. Cheers, Peter ☺️

[@arthurmann578]

I was just looking yesterday at a vintage motherboard with a Duron processor with MANY bad and swollen caps that I need to replace. It would lock up in the bios and the screen would sometimes scramble up. I would like to fix it but first I must find/buy about 15 capacitors or so. Lots of desoldering/soldering ahead in the future! 🤔

[@RodBeauvex]

I wonder if the bad caps affected performance any. One bit of advice I want to give is that if you should always replace any given type of capacitor with the same type of capacitor. I've had things stop working after going from tantalums to electrolytics. I think it has something to do with timing signals, which electrolytics aren't good with.

[@soulmata]

Such an interesting CPU. It was poorly timed and didn't do well in the market, but it also showed that AMD could do true innovation and did not need to solely rely on Intel's lead, which was a sign of things to come. K5 to K6 to K6-2 to K6-3 to Athlon to Thunderbird... it was a golden age for AMD for sure.

[@wishusknight3009]

I don't really consider the K6 a golden age. That didn't happen until thunderbird and went until early Barton when the HT p4's were just becoming too good for amd to keep up with. But the Barton CPU's were a dirt cheap cpu on an astonishingly good platform in the nForce2 that many of us stuck it out. They were competitive but didn't have the crown by the time T-Bred launched. However that just put the golden age on pause for a while until Sledgehammer... Ohhh my goodness...

[@soulmata]

@@wishusknight3009 I consider it a golden age because it was a long period of steady progression where AMD built up more and more momentum leading all the way up to AMD64. Then when Intel really hit back with Core it was them being not an underdog, but just an outright inferior product until Ryzen. So from K6 to Thunderbird compared to AMD64 to Ryzen, the first period was a lot more enjoyable.

[@wishusknight3009]

@@soulmata That is true. Though the athlon xp palomino was extremely competitive and top performer for some time until northwood. And Phenom 2 was also a great chip to get as well for a short time. Though it was never really a performance leader, it was a return to form in a product that was good enough to be a real alternative for a year or two. But I do love the barton ara simply because the steady platform advancements from VIA and nVidia were what made the athlon xp worth getting. Though I guess when one is considering what a golden age is... Thinking about it a bit more, I can see how those era's really arnt. They were an AMD backed against the wall fighting for their life.

The AM29000 Family is very interesting and the 29030 is a beautiful little piece of Hardware to own.

[@moeschizlac]

What motherboard is the 29030 processor compatible with? Can you run dos games with it? It reminds me of the Motorola 68k family that apple computers used to come with back in the 90's.

[@te0nani]

@@moeschizlac A few workstation boards. I never owned a board for my 29ks. These where used mostly in embedded systems (laser printer, Airbus flight computer). But the K5 is basically a 29050 successor with a x86 Instruction decoder on top for socket 7. And for DOS-Games: Not really. All 29k except the K5 are RISC-Instruction set Processors. As far as I know there is no popular DOS/Games scene for this processor line. So if you want to run DOS on it, K5 is the way to go. The performance is not awesome, the decoder is pretty inefficient. But that's as near as it gets.

[@richard.20000]

@@te0nani Exactly. Am29000 was using RISC instruction set. Today every X86 CPU is RISC based inside with old horrible x86 decoder in front. AMD was very ahead in time with K5 back then. X86 as horrible ISA shouldn't be alive in 21st century. AMD should have kept Am29000 instruction set alive and open it up for everyone. Jim Keller tried same K5 trick with common K12/Zen CPU development for two different ISAs: ARM/x86. Too bad they killed K12 after tape out.

As for the PR rating, I remember in the 90s that these ratings were based on PC Magazine benchmarks (ZD Winstone Benchmarks).

[@evibes512]

I lucked out and found an old E-Machines 333cs next to the curb being thrown away and it was Super Socket 7 with a Cyrix MII PR333. I've since bought a few CPUs to play around with including a P200MMX, K6-II+ 500 and a lowly K5 PR166 and have really enjoyed each CPU. Lots of nostalgia setting jumpers and dip switches and playing old DOS games. Thank you for your exceptional channel!

[@SledgeFox]

Thank you very much, your channel is a gold mine of interesting content. Brilliant!

[@Xaltar_]

I remember selling Pentium and AMD K5s in the 90s. We used to joke that PR stood for "Pentium Rating". Most people that opted for the AMD variant tended to be unable to afford the much more expensive Intel option so we did our best to make them feel good about their purchase. At the end of the day, 99% of users wouldn't notice the difference in performance between a Pentium 100 and even a Pentium 166. For gaming the Pentium 100 provided perfectly playable FPS when paired with a capable GPU and 35fps vs 25fps isn't something most people noticed in games like Doom, Rise of the Triad or Duke 3d. It was only when benchmarking and games that included more broad graphical settings became the norm that people really started to notice performance differences within the same platform (Socket 7, Slot 1, Socket 378 etc). I still remember most people in the mid to late 90's when asked what PC they had would simply say, "I have a Pentium" or mumble "a 486" under their breath. Very few people I knew/did work for knew anything beyond the marketing hype. When you found that guy/girl that said they had an overclocked Pentium 100 running at 133 with a 4mb Tseng Labs graphics card and 16mb of EDO RAM you got excited at finding a kindred spirit :)

[@Choralone422]

I owned an AMD K5 75Mhz CPU back in the day. I was building a socket 7 based PC at that time and didn't have enough money left to buy an Intel CPU. The K5 75Mhz was about half the cost of even a Pentium 75 or 90Mhz, over clocked a fair amount (using a Megatrends HX83 motherboard) and did the job until I was able to replace it with an AMD K6 200Mhz CPU about 6 month later. I used that machine all the way until winter of 98/99 when I replaced it with a Celeron 300A on an Abit BH6 motherboard. I ran that overclocked to 464Mhz for quite a while!

[@HighwayHunkie]

i just love these Tseng ET6000 cards. Still have mine from back then when i bought it new. Also 4.5MB MDRAM soldered on. Btw.. is the one capacitor between then PCI Slots a bit bulged? Not very common in that era or motherboards. Anyways, interesting comparison. I only have to of the K5 - the PR150 version with its uncommon 105Mhz that not every board can provide. But nice to have CPU.

[@kkolakowski]

Maybe for the future comparisons of CPUs of that era (1996-1997) also add some Windows 95 benchmarks - as it was starting to be more relevant than DOS for those CPUs 🙂 Great video as always!

[@anomaly95]

Finally a mention for the Am29k :) It's an interesting chip and ISA, but it didn't see much use outside of some fairly niche applications. Also neat that AMD used some of the new 29k tricks with the K5.

[@anomaly95]

The thin clients DO have a place! They're cheap and plentiful compared to the "vintage" or "retro" listings on ebay or other places. Also for parts. It's hard to get an older soundblaster or voodoo for a decent price since everyone seems to be building their own retro gaming rig right now.

[@matthewday7565]

I had a Cyrix, the rather wierd 6x86L - a non-MMX chip that used MMX voltage - and it ran on a Tyan Tomcat motherboard with a linear regulator that you could fry eggs on

[@arthurmann578]

I remember that the cooling fan on my old Cyrix CPU had to run so fast that the sound would nearly deafen me! You knew, though, that if you DIDN'T hear that sound you had better switch your machine off REAL fast or that Cyrix would go "nuclear" on your ass mighty quick and take your motherboard with it! Those were the days.....🤔😀👍👍 P.S. I think it was one of those Cyrix processors that ran at an "equivalent" speed to a Pentium 133Mhz CPU, but really could not quite "make the grade" even though it tried REALLY hard! I was relieved when I finally got a PENTIUM 166 to replace it with. So much faster and no more worrying about a "meltdown!" 👍👍

[@anomaly95]

@@arthurmann578 Did the fan noise compare to the Athlon days? I still remember the 60mm Delta black-label fans screaming just a bit away from where I was sitting. What were they called? FOP38's? Those also couldn't stop otherwise the CPU would meltdown.

[@arthurmann578]

@@anomaly95 I think I remember some people commenting about the noise those fans made you are talking about...🤔 The fan on my old Cyrix was so "tiny" to me, it was hard to believe all the noise that it actually was capable of making! I'm pretty sure that they did not last that long either because of the speed and because they were just sleeve bearing and not ball bearing. Lucky for me that I did not have it long enough to go out before I upgraded the processor to an Intel 166MHz. What a HUGE difference in the sound level of the Intel fan. I could hardly hear it!

[@rootbeer666]

K5 was out before Quake's release, although a lot of benchmarks go into architectural decisions of a CPU, for marketing reasons it could very well be that Doom was one of the chosen benchmarks to determine the PR number. Considering that back in those days all I cared about was playing Doom, I'd say AMD probably had a solid offering for $$$.

[@anomaly95]

Some people may find it odd, but Doom WAS one of the "killer applications" back then that required upgrading. I think I upgraded 3 times between Doom/DoomII/Hexen/Quake.

[@DoomWarriorX]

Very nice. Had a similar idea to benchmark my collection back in 2005 or so. My main goal was more to compare those x86 stuff against the UNIX-systems from Sun, HP, SGI and DEC. But also benchmarked some So7 combinations. Used NetBSD to keep the software side in check. Afaik from those benchmark i run the most interesting to me was the oggenc time of an 20min track or so. I keept those result even after selling all the hardware in 2008 or so: IBM 2V2P150GE P150+ 3.7 - 18217.852 Intel A8050275 SX969 - 17735.011 AMD SSA/5-75ABR E - 17000.381 Intel A80502-90 SX968 - 13978.796 AMD K5-PR100ABQ F - 12679.37 Intel A80502120 SY062 - 11361.742 IBM AVAPR200GA PR200 A - 11333.167 Intel A80502150 SY015 - 10410.907 AMD K5-PR166ABX C - 10157.52 Intel FV80502166 SY037 - 9736.795 AMD K6-166ALR C - 9368.251 Intel FV80503166 SL27H - 7943.87 I think the values are in seconds so lower is better.

Had this AMD cpu installed in my first PC which my family bought used in 2002 which was brought to town used from Germany in the end of 90's, that's when I also discovered doom and it has me consumed up to this time. I also played lots of dn3d and never knew about lagging and some quake which ran quite well. Gotta say win98se made the gameplay a bit slower with just 16mb ram and 1mb graphics I can't remember. Some speed up was acquired when it had 64mb ram installed. It also had ess FM audiodrive 1868wdm, it was impossible to have it playing the sfx in dos games. So on win98 I could only have Roland or opl3 music. On win95osr2 I could reassign the irq address, restart PC and have both opl3 playback and sfx for just one PC run. Dark times yet so much fun of being a kid and the games are still impressive if looked at from a certain perspective.

You can apperently get a PR166 to show as a PR200 but I am unsure what settings are used. Our other tech did once on a customers computer but I never found out what he did. I can only assume he may have used a 2x multi if that was possible on them. I have never actually had one in my collection except for a 75mhz version for a couple of months that I never actually used. And these cpu's were indeed interesting but sadly nothing special. It may have stood a decent chance if it was out a year earlier but it was still a very hot chip that couldn't clock worth a duck. Rumor has it, that little bits of its DNA went into Athlon, but I think that is only speculation based on some similarities in design principal between them.

[@SergiuszRoszczyk]

Back then I moved from Intel P75 to K5-PR100, mostly for cost reasons. What a huge mistake it was. It wasn't any faster, at least at my games back then, also my father's accounting software didn't work at AMD architecture at all (we had to wait for upgraded version). After that I moved to P133 from Intel and that was my last time I used any AMD CPU. I have had no knowledge of architecture difference of K5. I was happy with my previous 486DX4 so I thought it would be as good. Oh, how much it wasn't. I might give Ryzen a try now, given how good they look and how good benchmarks they receive, but at that time all that PR rating I considered a pure lie.

[@Ozfrank]

K5 PR133 has a 100mhz real clock, so it's has equal or better performance than 100mhz P-100. But PR calculating in many tests : In office tasks, where AMD CPUs like K5 and K6 was significaly faster than pentium and in a games where situation is not so good for AMD. So, PR calculating from many different tests as an average value, and so K5-PR133 will be slower than P-133 in games or multimedia tests, as we can see.

yeah. thanks for the hint. I saw that as well. Will replace them soon. 😉

I had a K5 PR133 but i cant find it anymore. Interesting cpu that i got cheap to uogtade my then gf 5x86 build. At some point i upgraded it to a k6-2 350mhz cpu that the machine still has in it to this day. Im hoping the k5 is still in my old computer parts tote so i can tryit out again.

I wish you do test one day ATi Mach 64 ISA vs Ati Mach64 pci

[@tengkusulaiman]

I my country, during k5 era, amd was considered low spec pc compared to intel pc. Later on Athlon got in market, which attracted them. I used k6ii 500mhz in 2000 and it faster than pentium that year.

Are you sure about the 29K? I've only seen that claimed on Wikipedia, and the cite didn't check out.

When I was a kid, my Dad bought us a 486-SLC-33Mhz PC and it was terrible. The SLC was basically a souped up 386, but that thing could barely even run Doom - perhaps 10fps on a good day. So I saved for two years and, in December 1996, I used all of my Christmas money together with all my savings and ordered a Pentium 133Mhz with 16MB RAM and Windows 95 from a local computer shop. I spoke with the owner extensively and told him all the components I wanted, put down a deposit and returned early January to pick it up. I paid the remaining balance, the whole thing came to around £1300, and took it home. When I booted it up, I was shocked to see POST report "AMD K5 PR133 running at 100Mhz". Thats not right! I thought. I ordered a Pentium 133Mhz! I PAID for a Pentium 133Mhz! But I had no idea what a K5 PR133 even was, so I called the store. The owner told me that the CPU I had was FASTER than a real Pentium 133Mhz, so he had "done me a favour!". I was confused, but the first few games I played on the machine - a demo of Diablo from a cover CD and a game called Firefight, ran perfectly. As did Road Rash. So I felt better. Then I installed Quake. And what a fucking shit show! My friends Pentium 100Mhz ran Quake WAY faster than my brand new computer did, and the only reason I had ordered a 133Mhz Pentium is that I wanted a very smooth Quake experience, for Wireplay. So I called the store back, but mysteriously, the owner was on holiday - and every time I called for months after I got the same message. They had ripped off a young 15 year old kid out of his entire savings and Christmas money. So - fast forward 11 months. I returned to that store the following December with a friend of mine. The worker was a different guy and didn't recognize me and, as my friend talked to him about computers, I reached over and stole a brand new INTEL PENTIUM 200MHZ CPU from behind the bench. I took that home, installed it, and Quake was SILKY SMOOTH, like butter. I was hitting over 60fps in some single player maps, and playing online was far more of a fun experience. That was a £200 CPU back then, which I figured was about what they had stolen from me the year before. If only I'd have had the confidence to buy the parts originally, instead of paying extortionate prices for a store to build it for me, I could have gotten a much faster computer for less - possibly even a 166mhz Pentium. But I didn't start building my own computers until about 1998. Thankfully that store went out of business shortly after I stole that CPU. As did most of the small computer stores in my town. Only the most honest and reliable ones remained, and some even remain to this day.

After seeing that Am486-DX4 90 at ~ 2:59 I couldn't think of anything else. What kind of CPU is that?? 😲

[@JPDuffy]

You didn't see the Am486-DX4 120 next to it? That's just bananas. I had a Pentium 60 back in the day, and here's AMD with double the mhz on a 486!

[@mrmobodies4879]

4:57 is that black cap inbetween the pci slots and 5:30 left cap bulging or is it just an illusion?

[@DoctorNatas]

I think the same. Two bad caps on this Asus...

[@ronch550]

Just wondering: would you guys use the K5 over the Pentium in an office environment?

[@chehystpewpur4754]

its bad that in 2021 these are the builds we have to be excited about...

[@Dr_Reason]

I had a K5, and then a K6-III 450.

[@happer2009]

Cool. But i had Cyrix M1 :-) !

[@intrinia2832]

Pentium rating, funny how times has turned. Intel now rating their 10 nm according to 7nm TSMC.

[@sonic2000gr]

I couldn't help but noticing a slightly swollen capacitor on the board...

[@CPUGalaxy]

yes. I know. I ordered already new ones. I am glad that my viewers are watching my videos really carefully 👍🏻☺️

[@calvinthedestroyer]

From what I remember the lower price was the BIG advantage.

[@ProBloggerWorld]

10:25 conclusion was real. Overall setup for AMD was significantly cheaper. You also got to consider motherboards for Intel CPU, which - surprise, surprise - used Intel chipsets as well, were roughly two or three times as expensive than an AMD setup mobo, CPU combined. AMD was a great bargain. That's why Intel came up with the Celeron CPUs.

[@seleccionmultiple2905]

I remember 16 years ago reading about how the AMD PR system was misleading, looks like that assesment was no too far from true.
