Nice benchmarks 😀

If you're open to suggestions;
Add K5 & K6 benchmarks.
Compare all cpu's at the same speed to see which one has the best performance per megahertz. (all with a 66MHz FSB, to keep it equal)
Maybe add A Pentium 2 233MHz and 450MHz to the mix?

Cyrix 6x86?

Ubercool! The jump from the MMX233 to the K6-2 300 is quite big.
Very impressive mau, what else do you have in store ? 😀

Voodoo 2 is much faster than Voodoo 1 in GLQuake even on a P100 !
Would never have guessed.

Yea the jump to K6-2 is quite dramatic. The 100 MHz FSB is likely part of the reason. One you have on-die cache things really start to fly.

The good old Pentium seems so out of date.

In terms of other exotic chips, donate them to me and I will add them to the chart 😀

What's next? Well I really want to look at some Socket 487 Pentium 4 stuff.

Voodoo 2 / SLI scaling on slot 1 and S370 would be interesting but I think I need a break from 3Dfx 😊

Is there a way to disable SLI in software?

That would make it easier for me to continue investigating other platforms (Slot 1 and S370).

Quantum 3D's Obsidian2 X-24 had a software SLI disable (obvious).

Can you test the Pentium MMX on 100MHz FSB (it should run at 300MHz with not too much problems) to see how it compares with K6-2@300MHz.

Back in the days I went from P-MMX 250MHz (2.5x100MHz) to K6-2 500MHz on some MVP3 board and I really didn't see that much improvement in games with Voodoo3.

Thanks for this benchmark, very good work. I'm always interested in benchmarks showing how GPUs scale, helps a lot when choosing what parts to use for retro rigs.

The latest 3DFX Voodoo 2 driver has a tick box to disable SLI. But it's missing the disable V-Sync boxes. However you can get these back by updating a DLL 😀

So I can now disable / enable SLI on the fly which will make benchmarking faster.

I will start tomorrow but everything is ready to go 😀

Slot 1 scaling comes first. I don't have that many CPUs, but a PII 233, a PII 350, a PIII 500, 600, 700 and 800 I believe.

And after that I will move to Socket 370 and test a bunch of 133 MHz FSB CPUs all the way up to 1.4 GHz.

You must have quite a test lab and loads of patience to change the processor, reinstall the heatsink every time with fresh thermal paste for these benchmark marathons or do you do it somewhat differently(and easy)?

As if I apply thermal paste 🤣

These CPUs run quite cool and the cooler I use is not the tiniest.

On the other hand I only need to do this once. And then... become immortal 🤣

Thermal paste is not needed for a Pentium. Just use a heatsink with a fan and you're fine (even without fan works as well). It's quite open and testing doesn't last long. These CPU's produce very little TDP.

I see that difference between a k6-2+ and a k6-3+ are small,the extra l2 cache doesn't affect gaming to much.

No pentium1 experience for me.

Immortality(if there is such thing) or not in the narrow minded world nowadays, your contribution is definitely way up there for us souls who have no means to gather data from such old hardware. It almost makes me consider buying a PCI voodoo card with my hard earned money. Looking forward to Socket 370 benching(can't escape applying thermal paste 🤣 ).

Thanks, greatly appreciated 😀

Ran into a weird issue and worth letting others know about it!

I'm working on Slot 1 Voodoo 2 scaling and started with a P III 600. I recorded all results, but when doing other CPUs and coming back to a faster model (750 MHz), the scores of Unreal with SLI where too slow.

I tried all software tricks, re-installing OS, different drivers, but nothing worked.

Then I remembered that I changed the RAM at some point. From a single 128MB stick to two 64 MB sticks.

So I put the single 128MB stick back and the results scaled correctly again. We are talking of a difference of 100 vs 70 fps.

Sad news is I will start all over again, the good news is that I found out what the issue was 😀

But what a weird one...

Found drivers (They are Creative drivers) which have the "disable VSync" tick boxes for Glide and Direct 3D and also a "disable SLI" tick box!

Works with all the games and makes benchmarking very easy 😀

Will you go all the way down to PII 233? 😀

That is the slowest chip I have, yes 😀

The fastest is a Coppermine 750 and a Celeron Coppermine-128K 900.

Beyond that I will switch to a S370 board.
