New test: 3DSpace: 286 = 15%. 386 = 19%. Best. I redid new archive, added more new programs. See first post.

12.5MHz for the ISA bus, that would explain something. So to make things fair you'd have to use "CPUCLK/2" for the 386. It is my guess, I do not insist on the truth. especially as I wrote above about what 386-25mhz with ISA=CPUCLK/2 can not catch up to 286-25mhz. if auto is disable, then you can …

http://s006.radikal.ru/i215/1601/53/f91e59afdc49t.jpg Two identical 386 baby-mobo, but with different chipsets: UMC and BIOteq. I checked and both run almost identical to 40MHz (3Dbench 16,8..16,9 fps). Performance is the same on VGA card. Hence the same for ISA-bus. But Bioteq no jumpers to 25MHz. …

Since you mention you underclocked the 386: Could you check the ISA clock? Maybe there is a BIOS setting for the divider? http://s011.radikal.ru/i316/1601/a5/98b1cc93b2aet.jpg if auto is disable, then you can change the parameter "AT clock select" on: 1) "CPUCLK/2" for high througput ISA.

Unfortunately, I have no ET4000. But there is available: Trident8900 (1mb), Trident9000 (512kb), Realtek (512kb), NCR (2mb) they were slower because of the high WaitState VGA<->ISA.

Thank you all ! 😀 I put links BENCH286.RAR in the first post. and put more pictures benchmarks. Please test your 386SX ? To Scali: You are absolutely right in your posts. I agree with you.
