Thanks, that was awesome. Appreciate all the work that took!

Quite interesting. I find it surprising how well the pentium pro actually does in games. It is much closer to the pentium 2 than I was expecting.

gonna keep be busy reading tonight!

If you REALLY want mmx on socket 8, get an overpriced overdrive chip. Those things run like raped apes.

Just have to ask, how do you know how raped apes run?

Good work.

What cache PPro did you use? I didn't see it in the word doc.

Hi, I should have clarified, that's a PPro 200 256K.

is there a specific reason for leaving the ppro memory timings on default?

There were no options in the BIOS to tweak them, as is to be expected with most Intel motherboards anyway.

Checked them out on eBay and the prices are insaine! Something special a socket 8 motherboard delivers that you cant get on a slot 1 board to justify getting theese? Maybe for Quad socket 8 boards or an ALR 6x6 they make sense. I have 4 Powerleap s370 to s8 adapters, so i may try them in a Proliant someday with some Celerons or underclocked P3s if possible.

sk8 overdrives have the L2 running at full speed. But than again you could just get a Pii450 and have a much better system with AGP and SDram.

But I rather have the overdrive, if the rice is right.

OK i see. They were the offsping of a Ppro and P2 love affair 😊

They are rather interesting, But sadly you can only use two of them in a system. If you have one of those ALR quad or 6 socket systems you can only use two overdrives.

ASCI Red, once the fastest system in the world used pentium II overdrives.

I'm surprised how PPro handles 44KHz audio in Unreal.
Seeing how the game automatically switches to 11KHz when it cant detect MMX, I was expecting a huge 44vs11 difference.

The Ppro is a rather surprising cpu in what it can handle.

Nice work!

some interesting results there. i wonder if the pentium pro suffers any penalty from running win98se (mixed 16/32-bit code), it would be interesting to rerun some of this on win2k. of course the pii has better l1 cache as well, i believe.

mmx seems nearly irrelevant in most cases from what i can tell, unless diablo 2 actually uses it, but i'd take the "pmmx>ppro" conclusion with a grain of salt for now. generally i think it would have been better to do all tests with the same amount of memory, 64mb to not penalize the socket7 system and use the same hdd for all.

What was the general loss in performance when running 16/32 bit code on the PPro? I can't imagine this being as vital as was propagated - seems more like a maketing "gag" of that era.
