Pentium is shining in Quake as its code is optimized to utilize the asynchronous FPU operations which are interleaved with FP arytmetics. This is well known paradigm of Quake code.
From the same reason the Cyrix CPUs were literally Doomed or should I say Quaked ;)
I had a 200 mhz Cyrix M2 back then too that I "upgraded" a Pentium 166mhz with MMX with.. I shortly downgraded...
@@barowt why? Which SW was a reason?
@@radoslawbiernacki Quake, everything ran decent except Quake.. at the time, I played that demo a lot. Until I bought the full game. That's just the DOS side, on Windows, I don't remember exactly why, but it ran way slower on anything graphical..
I still have that old Cryix too, my stepdad kept it, with some of my old computer stuff from 20 years ago.
Oh I misspoke earlier, it was a 233mhz Cyrix, my computer back then topped out at 200mhz....
Heck went from that, to a 1ghz Athlon, which blazed past everything I had at the time..
@@barowt yup, Quake was certainly a Cyrix company killer ;)
An example how one engineering decision can make company bankrupt. In terms of CPU architecture, super-scalar, means ability to process multiple instruction at the same time was a Pentium super power back in the days.
@@radoslawbiernacki It wasn't just Quake. We had a LANtastic network with NE2000 compatible networkcards for the office. And the drivers refused on non-Intel CPU's. The local computershop even leant us a PC with Cyrix-pentium 90 equivalent CPU. No network driver support.
Dude, this content is amazing, and your drawer of CPUs is... inspiring. You should have a lot more subscribers, wish you best of luck!
Thank you 🙏🏻. In one of my next videos I will show all drawers. 😉
.. Or weird depending on how you want to look at it
Confusing using blue for AMD in the graphs :)
My first "usable" pc I built from hand me down parts used this cpu overclocked to 160mhz. I even took this baby online back in the late 90's. Looking forward to the 160mhz test.
Did you worry about burning the CPU? It sounds scary to overclock an old CPU that isn't designed to shut itself down before permanently damaging itself.

Mine is working correctly on 150 Mhz without problems. Many have no problems with 160.
@@IARRCSim I had no problems with 160MHz on X5-133 - it worked perfectly for about 3 years.

In 1994 you could still buy a new 386 pc.
As far as I know Intel manufactured 386 up to 2007 for Boeing
@@CenturionKZ those were likely radiation hardened 386 cpus, quite specialized hardware
Why would you want to they were garbage? I hate it to 386 and 486 processes!

Nice that you also producing professional videos of your collection! PS: visitor of your cpu galaxy homepage and also from Austria
Thank you. I am happy to have also fans in my own country. 😊
@@CPUGalaxy More than you may think, hello from Salzburg! :) Keep up the great work! Not envious at all of your awesome collection... :D
You pulled open those drawers full of CPUs and I became jealous immediately. 😉👍
And here we are... Watching this video in smartphones with octacore processors running at GHz speeds and gigabytes of RAM...
I've lived the dawn of Pentium era and sometimes I miss those old, buggy, but funnier times... when a PC with 4 MEGABYTES of RAM was considered "the killer machine" ! Lol!!
So glad that back in the day after weeks of thinking what to get that I decided to go for a p75I with EDO ram instead of a dx4-133. (I also clocked that p75I to 90mhz then)
And now we compare the price on release... ;)
93$ for the AMD versus 964$ for the P66, i paid 150 DM for the 5x86 back in 1996 at the Hobbytronic in Dortmund. And yes, as everyone in our nerd clique, i overclocked it to 160 MHz for that extra Oohmp, making it possible to play Duke3D in 640x480 and Quake 1 in somewhat playable speeds.
On top of that crazy price, if you bought a prebuilt P66 you might get something absolutely dreadful. The 486-DX4 100 system I built (in 94-95ish) absolutely crushed my friends' Gateway P66. So much so that he got his parents to buy him a P150 "for college".. and that was the end of my computational supremacy. I actually used that system until I saved enough for an AMD K6 300 in like 98. The DX4 soooo slow by that point. AMD was very good to me in those days.
The biggest gain of the Pentium vs 486 was in the FPU, this is the reason for the big wins for the Pentium in 3D games - pretty much twice the performance per clock. Thanks for the video! :-)
Not really. There are A LOT of improvements in the pentium outside of the FPU. Actually, the only game that's using the FPU in the video is Quake. Doom and Duke3D don't even touch the FPU, at all.
@@ccanaves both Doom and Duke3D aren't polygon based so any improvements from floating point wouldn't matter.
They did a lot of hacks to get to the right performance level on earlier games, Id was excellent in that matter, even creating formulas that are in use until today in modern games to speed up or aproximate some calculations.
You are both wrong the AMD fpu is actually faster. But the intel FPU can be dual threaded. This is what John Carmack exploited to get Quake running at "playable" framerates.
The biggest gain was the superscalar design. Doom is a pure, 100% integer benchmark. There's not a single floating point instruction in there and a 66 MHz CPU is holding its own against a 133 MHz CPU.
Schon bei der Überschrift, dachte ich nur geil!!! Ich freue mich es anzuschauen.
That AMD 5x86-133 was a nice upgrade from my first CPU ever, a DX2-66. At 4x40MHz it had an integer performance close to the P90. But Quake really killed it off for me. I swapped the whole bundle for an AMD K5, which wasn't the most brilliant idea Quake-wise...
Haha I went from a Cyrix 486-33 (which was really a 386 pretending to be a 486) and the difference was night and day. That X5 served me well through my first 3 years of college then I went to the dizzying heights of a P200MMX so I could play Quake!
@@Zerbey on most performance terms it were the sis-chip the bottleneck
i know only one board of such kind clones which was really useable with socket 7 and that was an ALI with 1mb cache
I remember sending mine in to get a replacement P60 for the FP
holy crap ... 3dbench ... I have not seen that in over 2 decades ... wow. Brings back memories!
In these old games/systems, the sound card makes a hell of a difference. If the 486 had an ISA one, and the Pentium a PCI one, it was not a fair contest. I used to remove my sound card in my P75, and played games designed for a P166 or even 200 with a Voodoo card with no real performance issues.
Not just the bus, I had a Gravis UltraSound and games which used it instead of my SoundBlaster were noticeably faster. Both were ISA cards.
Pentium loves muddy brown! LOL Quake.....oh why oh why did that damn ugly bland game hold such domination in that era. I wonder how many people spent out a ton of extra money on an intel chip rather than a Cyrix or AMD because of benchmarks and reviews in magazines and on the web from that Fu*king game and then never played it, how much other software back then even touched the FPU? You'd have been far better off with a Cyrix 6x86 or AMD K5 at half the price for everything other than Quake, they were faster and so much cheaper, better an extra stick of RAM or a better bigger HD in your PC than buying an Pentium I think.
Anyway, great review and I really enjoy your content. Thanks.
the amd x5- 133 has a little secret. With a nice heatsink fan it runs stable at 160mhz by increasing bus speed of the board. So would be good to see how that stacks up against the pentium.
I did already some OC tests. 🙂ruclips.net/video/ysMmAVNKrFY/видео.html
The results are pretty much exactly what I would have predicted - Pentium's FPU is a lot faster and it has better memory bandwidth (66MHz/64-bit FSB), but at twice the clock speed, the Am5x86 pulls ahead for integer math (P5 is faster per cycle, but not quite double) or anything that cares a lot about memory and cache latency. I bet for tests that fit into the 16k L1 cache on the 5x86 versus ones that don't fit into the Pentium's 8k, you'd see the AMD chip take the lead there too.
Good battery of tests to smoke out exactly those kinds of distinctions, though!
You use red and blue colors for graphs ... and choose red for Intel. WHAT? Other than that, great video, thank you.
I have the very same Asus PCI/I-P5SP4 Socket 4 mainboard with my Pentium 60. I use a Adaptec AHA-2940 to be able to boot on a scsi cdrom. This way i'm able to boot UBCD and Memtest
This is amazing! Why haven't I found this before! Right up may alley. This is back when computer hardware was really fun. Today I really don't feel the same "fun" with the hardware.
I thought it would lose by >50% in quake but it was only 25% behind. Way better than I thought. Quake is not really doing anything special to take better advantage of the new technologies in the pentium; it probably has some instruction reordering in an inner loop in the renderer to keep both U and V pipelines better fed by matching up instructions or something, but the big thing is that the pentium just has better floating point performance.
I am curious how you clocked the AMD...I had one DX4/100, at one time, and I believe my mother board was configurable...to instead of 33.33MHz clock tripled...I configured my FSB as 50Mhz like the original Intel DX50 and clock doubled, so memory transfer and I/O totally rocked! One of my friends actually got one going overclocked at 66MHz. I am wondering with the nice L2 cache, I think that you might be able to make the front side bus to 66MHz and clock double to 133MHz, the AMD 133 CPU. Did you try that?
CobraTheSpacePirate there was never an option for a 66MHz bus on Socket 3. Nonstandard bus speed didn’t really arrive until Socket 7.
Maybe I am thinking about a motherboard that had a crystal can in there. Like the actual Intel DX50 motherboard and replaced the 50MHz crystal with a 66.666MHz crystal...
Just wonder about SpeedSys RAM moving rate, Pentium looks like 3-4 times faster.
It's a bottleneck of 486's systems.
My conclusion from this is that Pentium = 486 SLI 😂
3dfx or Nvidia SLI? 😛
It would be interesting to see that 486 set at 50Mhz x 3. With a 33Mhz bus, it's starved for data.
I tried, but unfortunately I did not get a post screen. At 40 MHz and the cpu at 160 MHz it was posting and performing like hell. 🙂
@@CPUGalaxy Did you try a different videocard? Because I've seen in other reviews that the Tseng has issues at 50Mhz bus speed.
I remember, that my amd was working on 3*50, graphic chip ARK2000MT
i got a Socket 4 board, it posts but the dallas chip is dead, and worse, it's soldered on to the board. it has a pentium 66 chip with 8 mb fpm RAM.
I have a big CPU collection too ... every gen from 8086 up
Very cool video! I've never seen an AMD X5 labeled DX5 before! Thanks for sharing!
I have a gold heat spreader big P5. But back in the day, I bought the 586 133mgz because it was quite a bit cheaper and bought it at a computer faire off a table from a CPU vender. A big jump for me from the a 25mghz 68040.
My first harddrive was 18mb. When I blew a lot of money on a 400mb harddrive, i thought I'd never need any more harddrive space ever again. When I started bringing junk home by the truckload, 400mb became the bare minimum Win95 install, I was using 650mb to 1.2gb drives most of the time and 400mb was almost a door stop.
I've still got a barn full of 486's... no idea what I'll do with them. By now, they could only be sold (if at all) as hobbiest nostalgia boxes. I thought of calling them Blitzboxes, because if you stay in ANSI mode, they actually are really fast... like on a Linux command line. With only 32mb RAm th ough, you won't be opening many 1990 era web windows...
Now I use 8 core processors with 32gb of RAM so.. there's not even the impetus to touch one, let alone connect the rat's nest of wires together to fire one up or anything out of my antique collection. I use to love all these machines, now I can't even bring myself to touch them... It's hard to explain why because I don't know. For decades I saved these from the dump when others discarded them as trash. Now to me too they are like trash... 30 years after.. they became trash.
By the time i was playing any of those games, I had a AMD (I forget which 233/266/300/333)mghz 3DNow processor so... the differences between the P5 and 486 were a mute point for me. The only thing I did with the 486 was Win95 and a webbrowser. I.e. stuff a P5 would not of blazed past it in...
"68040"😲 Apple or Amiga?
Why do you keep saying 40 86? It's 486,..
My first was a pentium 75 and it served me well. Windows 3.11 then upgraded to 95 was awesome. My 9700k is no slouch now😛 love a good old tec video.
I find you videos on retro PCs well made and I have an emotional attachment to the 486: the Intel 486DX2-66 was the processor which I used in the first PC assembled and configured by myself :-)
The only thing I'm not happy with is your final summary table: you are adding "apples to oranges". I suggest you add together the relative difference in each test and not the score of the test itself.
Here is how I would conclude the comparison, AMD DX5 over Intel Pentium (assuming equal weight for each test):
SysSpeed +1.2%
Doom +2.6
Quake -24.7%
PC Player -13.5%
3D Bench -7.5%
Checkit +10.6%
So AMD DX5 results 5.2% inferior (-31.3% / 6 benchmarks) to Intel Pentium
Thanks for rhis awesome video. Keep them coming please
A Pentium based system in 1992 was five or six thousand whereas the 486 133 could be had for about half that.
90% of the performance for a tenth of the price.
This is why the price of PCs started to decline quite sharply.
My first PC was a 286 at 25mhz, my second was a 386 at 40mhz, I was (early 90s) cutting edge...
my first was a cyrix 486 dx2/66 with 4mb of ram that later got upgraded to 16mb
Bit late to the party with this video, but that's the beauty of DOScember, it helps us find other interesting DOS-related videos!
My first computer upgrade that I paid for and installed myself as a kid was a 133MHz AMD 5x86. It replaced a hand-me-down 66MHz 486, and was definitely a leap forward in terms of performance. The AMD was definitely marketed as a Pentium-class 586 competitor rather than a 486, and didn't have 486 marked anywhere on the CPU. I paired it with an S3 Trio64 video card to take advantage of the new PCI bus. This was probably early 1996; Pentiums had been around for quite some time, so in hindsight I probably would've been better off getting a second-hand 90/100MHz Pentium.
Anyway, it was fun to see how my old machine stacked up to the competition. Thanks!
I still find it hilarious that I'm watching this video with internet faster then the cache of those old CPUs, lol.

@@FabianoMaiaFranco Bandwidth, not latency. Lmaoooo
You're right. I've not noticed the bandwidth speed. It's curious indeed how we could get things done in those days with such a slow hardware. Programming needed to be much more efficient than nowadays.

My first CPU was a 166mhz P1, used it all the way to 2001 until the 1.3ghz athlon.

From Wikipedia (about P5) : "Much faster floating-point unit. Some instructions showed an enormous improvement, most notably FMUL, with up to 15 times higher throughput than in the 80486 FPU". No wonder Quake really shine on it.

Since you have a socket 3 board with PCI slots, it would be really interesting to see how the 486 (66MHz DX2 and your AMD 133MHz) and the Pentium socket 4, cope with games likes Quake, if you were to add an early Voodoo graphics card.

I was all about the Pentium, really stuck with Intel back in the day. Played all those games even as Beta releases. Never bought into AMD, still haven't but if I were to build a new PC now, would totally be getting AMD. And since I'm 90% Linux, I'll stay with the platform that Linus Torvalds uses.
just fantastic video! I love it

@@CPUGalaxy 8088 vs 8086 vs v20 vs v30, clock for clock
I had an ADW that only went up to 160 MHz but not permanently stable. Once I had an ADZ in my hand, which I brought up to 200 MHz by 50 MHz FSB. I cooled it with a Peltier, but the heat sink was much too small, so I could boot Win95, but it crashed after a short time. The heatsink got so hot that I couldn't even begin to touch it. Maybe you could try again with more modern technology? Unfortunately, I still have the ADW.
Pentium has long RAM access because it's a wider bus (as hinted at by the "8 bytes" instead of "4 bytes" in the 486)
Yes, the access time is a bit longer, but it's getting twice the data in that time. Will it make up for it?
Who knows! That's just the theory.
Architecturally I think the Pentium is a huge win, but the incredible clock speed and equal FSB of the 486 will win it here, just a preliminary guess. It will hurt in Quake because of stalled FPU thing.
Rather thanjust AMD 486 DX5-133 vs Pentium 60, it would have been nice to see some combination of Cyrix 5x86-133GP/4X, AMD 486DX4-120, and Pentium 66 included. Then an AMD 5k86 P75 vs Nexgen Nx586 P80 vs AMD K5 PR75 vs Pentium 75 for a battle at 75MHz. Throw in a Cyrix 6x86-80 for kicks. And last maybe an AMD K5 PR90 vs Pentium 90 vs Cyrix 6x86-P100 vs Nexgen Nx586 P100. Surely that sets up Cyrix 6x86 P100 vs Cyrix 6x86-120+ vs Pentium 100 vs Nexgen Nx586 P110. Could even throw in the IBM 6x86 P120+ or the ST 6x86 P120+, but these are probably too rare to find.
My first PC worked on AMD P75-133MHz Overdrive. And I overclocked it to P90-160. :) Of course native pentium was better in Quake and winamp. But as a cheap upgrade the overdrive processor served good enough. When I was a student I had been using it during two years until I got Intel P100 and soon after that Celeron 333 (with overclock ability). Doom, Quake, Warcraft II, C&C - it was an amazing time.
By the way - the worst chip I've seen was a Winchip. It was clocked to 200 MHz. And it was a complete disaster when someone tried to play any game using this processor.
The 5x86 is an example of the last/best 486-class CPU. The P66 is an example of the immature 1st gen. Pentium. The 5x86 would have cost somewhere around USD 125-130. The P66 about USD 700. The Socket 4 mainboard would have cost somewhat more as well. A friend bought an early P60 with the the infamous FDIV bug. Even though he planned to use it professionally for econometric modeling, iNtel did not replace it for some time. I never bought a new Pentium I CPU because iNtel deliberately blocked the P55 266 mHz for desktops. It outperformed the PII 266 mHz. Embarrassing for iNtel.
I kind of envy your S4 board. My VLSI-based Digital board is definitely slower and on my test bench it could never beat an Am5x86 in a decent ALI or UMC board. SiS496 is only good _before_ one has to take video performance into account, PCI VGA performance is quite crappy on the SiS496. Maybe it could be a bit better with VLB...?
Other than that, the Quake benchmark is quite surely a win for the Pentium. That's the program that finally used Pentium's pipeline FPU to its full potential, and because of this even later challengers were left behind by it (even AMD K6-2/3 had no FPU pipelining!)
Oh, and one more thing for me to envy of you: That fully ceramic P5 CPU of you! I only have -60s with metal heat spreaders.
I just finally got a 5x86-133 from AMD. My motherboard supports it, but when the machine boots it says DX4-120. Every benchmark program identifies it as the 5x86, so I don't know what's going on. It also is confirmed to be running at 133MHz. My results were just a bit faster on Quake, 14.1 I was using a Matrox Mystique 4MB.
I ran the X5-133 in my everyday rig all the way into 2000, even after I had built much stronger machines for other people. For day-to-day use it was still a competitive CPU. But as these benchmarks showed, it was no way equal to AMD's PR rating on anything that required FPU performance; a 486 just couldn't match a Pentium there even with double the clockspeed.
AMD actually rated it at PR75, which they got away with by only using business application benchmarks and the fact that the Pentium-75 ran on a 50 MHz bus, which sometimes made it slower than a Pentium-66 running on a 66 MHz bus. But even for what the X5-133 couldn't do, it was very useful for keeping 486 machines viable for years after 5x86 and even 6x86 technology was available.

Quake relies heavily on the FPU and that was much stronger in the Pentium CPUs (compared to the 486).
Still have an old system with an AMD Am5x86-133 Mhz and AMD compared it to a Pentium 75. That claims are not completely off, even if some FPU-demanding software will run slower on it.
AMD 5x86 it is a pentium but with only PIO-modes of HDD - no DMA modes at all... sis496\497 no have busmastering
pentium chipsets have as minimum MW-DMA modes - it is a accelleration
An interesting fact. The AMD 486 DX5-133 could ran the Star Fleet Academy demo. The game was playable, except when the explosions begins. then the game slowdowns. I know very well this,because I played many times the demo on my old 486 DX5. This games requires a Pentium 90, but looks that (at least the demo version) don't checks the CPU and don't uses the Pentium instruction set.
Surprising results, I thought the 5x86 would win everything but quake by a narrow margin. The 486 was a way better value at the time though and since many of us knew these would almost always run at 160mhz it extended that value further.
I'm pretty sure i picked up my cpu with a motherboard for $99 in the spring of 1996. The motherboard was dead on arrival and i returned it and kept the cpu. I had an amd 486dx4/100 of the board i already had and ran it at 120mhz for a couple of weeks then decided to try 150mhz(I didn't know about setting to 2x for a 4x multipler at the time). Later on, i knew how to set 160mhz but it ended up being slower due to the slower vesa bus. Good times, and all from a chip that cost me $30-40 after i returned the dead motherboard.
Was wondering what cpu, and stuff to go with for my DOS Machine, sadly using 86Box, but still, it works, I was considering a high 486, but instead went with a a socket 7 Pentium 133mhz.
6:54 - "a RAM bank is 4 bytes wide" read 99ns, write 61ns - 486
7:48 - "a RAM bank is 8 bytes wide" read 204ns, write 183ns - Pentium
Any thoughts anyone? -
Maybe if you changed the jumpers to maybe 3x40/120 or 3x50/150 - maybe it could be the pentium at 4x40/160 -Anyway I played Quake at 150 as far as I remember making the buss 50 would or should change the graphics card bus -but Im not anymore shure -its been 25 years since
Nice collection.. I have a few old cpus myself but nothing like this.. Thanks for the video.
Why is the DRAM access time so different?
How did the Northbridge FSB work? Confusing that the DRAM controller was outside for so long.
The Pentium didn't perform better in Quake simply because of higher FPU performance, but because the FPU didn't stall the integer unit, unlike on the 486. Quake uses integer and floating point operations in parallel and that's why 486 CPUs struggle so much.
So... a 486 needs to run twice as fast as a Pentium to match it. Very interesting. Now I just have to run a 486 at 400MHz to match a Pentium-200.
These tests show that it is not a matter of processor speed, but of architecture and optimization. And the 66 MHz Pentium was on par with the 133 MHz AMD of the previous architecture. At the same time consuming less energy.
I would have thought that the amd would win. Pentium seems to handle 3d graphics better. I once tried out a voodoo card in a 486 dx2-66 system, and the 3d card made quake quite playable! So with a 3dfx card, there would have been a tie i think.
I though AMD would have won just because of that memory timing, but back in the day, memory speed didn't matter much, most of the time was actually spent processing things. But still the AMD lost by a tiny amount of parallelism Pentium was able to extract from the FPU.
yep i had 486 dx4 100 at that time and my classmates had pentiums 100 or even 166mmx, my life was suffering when i tried to play quake with those 9-11 fps)
Ok i built a lot of CPUs back then an i can tell you me my friend Greg sat around in dismay that a P66 that i just paid like a 1000 bucks for was not much faster than a DX266. Granted it was a very first gen ASUS board that had bodge wire on it.
I am happy I start my jurney with computers from Pentium era and early 3D. Mid 90s Such a nice transition time. And yes, Quake was a big HIT at tat time. I played it a lot.
Thanks for sharing and good nostalgia feel
I loved my X5-133, but Quake is the reason I ultimately decided to upgrade to a Pentium a couple of years later.
Quake and than mp3.
Internal access of blocks in AMD makes a countable difference as explained in "HENNESSY and Patterson"
I didn't realize the pentium was out for so long while 486 chips were still being developed. Pretty interesting times :)
The Doom performance with the two looks kinda logical.
The Pentium uses a 64 bit bus and the 486 uses a 32 bit bus, but the 486 runs twice as fast.
I love the chonky sounds and clicks that some of the hardware makes when you install it. Old school computer-builder ASMR.
Why do you keep calling it the "forty eighty six"?
Quite different today. OG Pentium fit the slogan "do more faster" but today's Intel chips are like "do less faster" in regards to IPC deficiency against Ryzen.
Wow....that was early double-digits for me.....took me way back.....remembered many of these debates from back then
Nice test!
Is it possible to do a benchmark with the 5x86 133 p75 vs is amd 5k86 pr75 (K5)?
Add more cpus to video: cyrix/ibm 5x86 100-120 MHz and podp5v83 ?!
There was Pentium 50 MHz - was most reliable.
While the AMD had a huge advantage over clock speed, it also had a huge disadvantage on bus and ram speed. The motherboard could not feed the 133 fast enough to overcome the Pentium 66.
Pentium required software optimization, otherwise the code was not executed efficiently.
Cache is slower than modern ssd disk 🤦😱
welcome to some history lessons. With this performance we had to deal in the past. 😉
this is interesting the sis chipset must be very kind to the amd or very unkind to the pentium ive never seen the am586 beat a true pentium on any of my hardware, even the pod83 on socket 3 tends to beat the the am586. also interesting phil put together that benchmark suite but i will say attempting to playback mp3 or any compressed audio formats is another way to put chips of this era through their paces and also showcases chips with strong fpu in a non gaming workload actually one load the cx586 tended to match or beat the pentium and leave the am586 trailing behind even if overclocked
Ah the first generation of pentiums... try to do some FDIV with it ;) I remember well back in the day how a friend bought the 60mhz version and I just went for the DX-4 as it was cheaper... totally shocked how it blew my DX4 away in many areas :)
yeah, the pentium was very impressive at that time.
It looks like that a Bios patch can change the micro ops of the CPU specially to fix the fdiv-bug.
An i9 10900K and R9 3950X will be on that spinning shid 20 years from now

Pentuim is superscalar (two pipelines) and AMD 486 is not (one pipeline).
I got two big Pentium 60 and 90 - they run quite hot - unfortunate unknown issue with badman-robin board
I see that the colors on the diagrams are not so right: Intel should be blue, and the AMD should be red (or orange like you did).
I had this AMD in 90s and this video explains much.
P66 has a floating point bug, just for that reason the am486 is better cpu.
You have beautiful maiboards, it's a very big problem to get one too :-(
I've always wanted to see someone try to play GlQuake with a Voodoo1 card installed into a PCI-capable 486 motherboard like you showed, with a top-end 486-class CPU. I know 3dfx specified a requirement for a Pentium processor with their Voodoo card, which has always left me to wonder whether such a setup with a high-clocked 486 and PCI would work at all or not.
It works there are multiple vids on RUclips of it.
As you can already reach around 13-16 fps in Quake, with highend 486 system, with fast PCI graphic card, for sure, you'll get close to 30 fps, with voodoo card, as it will take part of the CPU load on itself.
I had this exact setup and it ran quite well but you had to keep it at 640x480 to have a playable frame rate. The Voodoo 2 was much better.
@@Zerbey Voodoo 2 was better even on a 486? I would have expected the setup to be CPU limited. V2 has so much power especially in SLI, it scales all the way up with the 1GHz+ Pentium III's. Would have guessed a V1 would max-out a fast 486 chip.
@@angieandretti I was running on an AMD X5 and Voodoo 2 was definitely faster, but it was much more stable when I upgraded to a Pentium.
