I wonder though if CCD+DCD is any different than L1D+CCD+DCD?

I've just added my results for my Pentium MMX233 at 233 and 133 clock speeds with every possible combination of caches and TSRs. We can compare to Ivader's to see differences between 64MB vs 128MB RAM and VIA MVP3 vs Intel430TX chipsets. We're both using the same GPU (V3 2000) with the only difference being he is using PCI and I am using AGP.
It's a great chip and has a lot of advantages over the K6-2/III+ in terms of 386-486 scaling.
I'd like to match a specific 386 or 486 machine for various settings but it's really hard for me to make sense of the real machine benchmarks (also found in Phil's VGA benchmark sheets). As someone who did not own a PC back then it is very confusing... especially the SX/DX situation as I could've sworn from what I've read that SX chips were slower than DX. Yet I see i486SX-25's on there that have higher benchmarks than the i486DX-33...

The Pentium isn't the only way you can play Ultima VII on Socket 7. On a hardware Turbo-switched Socket 7 motherboard, the game speed is immune to cache re-enabling done by this game. This means any CPU compatible with S7, and with enough top-end performance can be scaled down to a suitable speed.
You can also achieve similar results with S7 boards that can force L1 cache policy from Write-Back to Write-Through (slow), and Ultima VII fails to renable L1 because it's still enabled. So, any compatible S7 CPU can work with enough top-end speed, too.
