After a long seek & trial period I finally managed to get my "ultimate" Doom hardware together...
-LuckyStar LS486E/Rev.?
-32MB EDO ram(50ns - yes, overkill)
-Matrox Millenium II
-Am5x86/ADZ
well, everything's quite standard fare, BUT the cpu makes all the difference, as
it runs at 180mhz with 3.x volt at 60mhz fsb with the clock divider(JP19) set to yield a PCI clock of 30mhz
I tested the rig with Quake and it also survived without a hitch. I will install Windows and if it succeeds I'll let the system run a few hours under various tests, BUT we'll see.
Cache has been disabled as, even with a 12ns tag, it couldn't keep up with the 60mhz fsb and at (3-2-3) would slow down the system. If 66 are possible I'll update the thread again but I doubt it.
I'll give more info/comparison once I'm done with visualizing all the data I have collected, comparing UMC/SiS 486 systems(50,60,66,150,160,180 @ 33,40,50,60 fsb[1]) and Intel LX/SiS 50x Pentium66 ones. In theory many values but in reality only a few options can and will be dealt with. IntelDX - WT, IntelDX4 - WB and the handy Am5x86 are part of the regime. The Pentium boards will run a Pentium SX948 overclocked to 66. Latter will feature scores submitted by generous owners of Intel LX based boards I do not own.
Feipoa has done magnificent work already on a multitude of cpus so I'll keep my work short and niche'y.
Doom shareware 1.9, demo3, default.cfg/screenblocks 9 yields - 75.2fps
3DBench2 - 105.6 fps
[1] 60mhz fsb only SiS and maybe UMC IF the board is cooperative(one was, another wasn't). Not all variations of fsb and cpu clock, 24 in theory, will be benched or are of course even supported.
