So I'm back to working with 486 gear and MS-DOS 😀
I wanted to test all my ISA and VLB graphics cards on a 486DX2 66 and see how they all compare.
System specifications:
Biostar MB-1433/50UCV-D PCB VER: 2
8 MB 70 ns memory
256 KB 20 ns Cache
Intel 486DX2 66
BIOS defaults loaded
ISA IO controller
The 486 is an average system I would say. I tried faster Cache and memory timings but the system wasn't stable. Left it at BIOS defaults. The ISA bus speed is set to CPU Clock / 4 which gives 8.33... MHz.
Some graphics cards only have 256 KB of memory, so no results for SVGA. Other cards needed UNIVBE loaded, but even then some glitched out. Easy to see in the missing colours for those results! UNIVBE wouldn't work for the ET4000 to get PCP Bench SVGA going, but
Benchmarks run are:
- 3DBench 1.0
- 3DBbench 1.0c
- Chris' 3D Bench
- Chris' 3D Bench2 SVGA
- PCP Bench VGA
- PCP Bench SVGA
- Wolfenstein 3D
- Doom
- Quake
My thoughts:
- I don't have any higher end VLB cards, the CL cards are the best I got
- Looking on eBay, CL VLB cards are easy to find and not too pricey
- ET4000 or S3 VLB cards seem hard to find and / or expensive
- WD ISA card is the fastest by the tiniest of margins. It also doesn't need UNIVBE, the ET4000 does
- ET4000 also very fast
- ISA CL good performance
- Avoid very old looking cards and Trident / OAK cards
- OAK ISA card: The decelerator. Maybe useful for slowing down fast machines?
