Coolies I will update soon!

Update. I had a strange problem. On every other pc the disk worked ok, but on this 386 it kept showing packed file error. And, as it also didn't recognize the HD I had in the case, I thought it may be some sort of incompatibility between the controller and the m/b. So I replaced it and it works fine. Now, running the 1.0 version of 3dbench, I got almost the same results. 15.8fps on normal setting, and 17.5 by raising the at bus speed.

We could need more scores for ........ Super Socket 7 stuff ...

Here's a SS7 3DBench2 score.

Intel-PentiumMMX-66-2.5-166-P5BV3+Rev:B3-VIA_Apollo_MVP3-1MB-AGP-Voodoo3_2000-16MB-Defaults:Optomised-retrogames100. Score:125.2

I then tweaked the BIOS options, to make the system faster, and reran 3DBench2. Curiously, I got the same score.

Intel-80486SX-25-1-25-AsusPVI486SP3-Sis496/497-256KB-PCI-S3_Virge_GX_Nitro-4MB-Defaults:Optomised-retrogames100
= 20.0

External cache disabled = 19.2
Internal cache disabled, External cache enabled = 7.8

CPU change. DX4-100 write back model. Score = 62.5
External cache disabled = 55.5
Internal cache disabled, External cache enabled = 11.9

Conclusion: There's probably more flexibility using a Slot 1 system (lots of bus speed options, CPU speed choices, and cache disabling), when you want to emulate the system speed of a 386.

Could you please bench the 486SX25 with an ISA card? Most of the earlier 486er were ISA only, so this would fit well to the SX25. Although the Intel Saturn chipset might be a bit faster anyway.

Here are some low-end 486 results:

I'm sorry, I don't have a single ISA video card! However, 5u3 has just benched marked this exact mobo (including same revision number) with an ISA card, and his SX25 (5u3, did you mean SX?) score drops from 20 to ~13 when switching from PCI (same video card as mine) to ISA. That's a very interesting and valuable performance change.

Nope, I tested with a 486DX, but it shouldn't matter for this benchmark anyways.

OK! Edit: Ah, I see how you've done the benchmarking. Take one CPU, and adjust the mobo's bus speed for the 25, 33, and 40 speed tests.

How about a Duron powered mobo!

Thanks for the 386 / Pentium and Socket A results 🤣

Some more 486 results coming up...

Here is 486DX4-100 results with the same VLB graphics card that I previously tested in a 386. The CPU is Intel with Write Back cache enabled.

Intel - 486DX4 - 33 - 3 - 100 - Asus - VL/I-486SV2GX4 - SIS471 - 256kiB - VLB - #9 GXE64 (S3 864) - 2MiB - aitotat - 66.6

I decided to play with BIOS settings and found out that setting Local Bus Ready from Sychronize to Transparent increased results to 71.4. So please write the 71.4 to the table since I'm using that BIOS setting from now on.

Edit: 27.0 with Turbo disabled.

I just noticed that CPU Clock and Bus Clock is exchanged in the table for my result of the 486SX (the only one).
Seems we lack alot results for SX - Systems.

Here is the last batch of my 486 bench runs. 12.9 to 90.9 on one board! 😁

That must be the fastest socket 3 board on planet earth! I notice it's a PCI board. Looking at your awesome score, there doesn't appear to be any sign of the infamous PCI "suckage" that is commonly associated with PCI and this type of board. What's your view on this? Generally speaking, is a socket 3 PCI board perfectly satisfactory, or would you consider a decent VLB/ISA board to be superior to all PCI boards?

Can you explain what you exactly mean with "suckage" ?
Regarding the PCI bus performance it can be stated that it depends on the chipset.
Are there any good 486 chipset guides existing on the internet ?

I assumed (incorrectly perhaps) that generally speaking PCI performance was poor. Suckage = poorness.

Ok, then I understood it right and as I said, it depends on the chipset.
I have motherboards with all the chipsets that were common back then.
From my experience the following conclusions are proposed (these results accord with some pc magazine articles from that time):

First group (PCI bridged off the VL-Bus, mainly produced until mid-1994):

VLB Chipset / Bus Bridge device
VIA 82C486A / VIA 82C505
Opti 82C802G / Opti 82C822
ALI M1429 / ALI M1435
Contaq 82C596 / 82C599

VIA and Opti -> slowest PCI solutions (~15 MB/s)
ALI -> only bridge device with good performance (30-35 MB/s)
Contaq -> mediocre (20-25 MB/s)

Second group (true PCI designs):

Intel Saturn/Aries
VIA 82C496/82C505
SiS 85C496/85C497
ALI M1487/M1489
UMC UM8881F/UM8886F

No exact data at the moment, but I would suggest this performance order: Intel > UMC > ALI > SIS > VIA
