Quick and dirty test of these cards, as they often come up in DOS PCI card conversations. Might be useful for some folks.
Other people have done much better testing but maybe not including all 3 on the same system.
Benchmarks taken from Phils DOS benchmark.
The cards:
Jaton Video Magic 128 (ET6000) 2MB MDRAM
Apocalypse 5D (ET6100, PCX2, DEC PCI Bridge) 4MB MDRAM
Legend 64 (ARK2000) 2MB VRAM
Test System:
AOpen AX3S Pro-U (815e B stepping chipset)
Pentium III-S 1400
2x 256MB Infineon PC133 2225 modules
Athlon XP S462 cooler, nothing special
No sound card installed, onboard sound disabled
Tualatin 1400 @ 1400MHz/1.45v/10.5 x 133.6MHz Bus/133MHz 2,2,2,5 SDRAM/33MHz PCI
Codeblock version
ET6000 ET6100 ARK2000
No graphics booster
Quake VGA 243.8 245.0 236.0
Quake 640x480 72.4 71.9 (Need UniVBE)
MTRRLFBE
Quake VGA 252.9 252.7 Not compatible with MTRRLFBE without UniVBE
Quake 640x480 72.2 71.9 "
Fastvid
Quake VGA 252.9 254.9 231.9 (Doesn't work properly on 815E?)
Quake 640x480 72.3 72.2 (Need UniVBE)
UniVBE + MTRRLFBE
Quake VGA not tested not tested 231.2
Quake 640x480 not tested not tested 78.6

ET6000 ET6100 ARK2000
No graphics booster
Quake VGA 283.6 288.6 267.3
Quake 640x480 83.6 84 (Need UniVBE)
MTRRLFBE
Quake VGA 291.3 297.4 Not compatible with MTRRLFBE without UniVBE
Quake 640x480 84.3 83.6 "
UniVBE + MTRRLFBE
Quake VGA 294.6 297.4 231.2
Quake 640x480 84.3 84.2 87.7
Quake 800x600 43.1 57.7 58.3

Notes
Quake VGA = 320x200 resolution
Repeated benchmarks at 640x480 vary, for example 83.6-84.3 so they can be deemed equal and will be CPU bound. some 3D cards tested higher so must be a Tseng design limitation.
Due to the Apocalypse card having a PCI bridge, the mb defaults to turn on integrated graphics at boot no matter what is set. So this was left on for all tests.
RAMDAC comparisons differ by vendor for the ET6000 and ARK2000

Performance conclusions
ET6000 vs ET6100 performance is negligible unless the PCI bridge is holding back the ET6100. edit - ET6000 struggles at SVGA, possible due to 2MB althought the ARK does well also with 2MB.
The ET6100 does pull away just a small amount when the CPU is overclocked, checked several times with reboots.
The ET6100 didn't seem to under perform with the PCI bridge like some people were indicating, the Apocalypse 5D sonic might be different?
ARK2000 comes close in non enhanced performance but has some VESA 2.0 and fastvid issues that may or may not be resolved with more time UniVBE fixes this.
This combo of 815E chipset and Tualatin 1400 benefits only a little from DOS graphics boosters and has good PCI performance for these limited tests. (My 440GX system shows much bigger gains from using boosters)
RAMDAC comparisons
Subjectively:
Legend 64 - Not great, serious vertical banding issue visible in Windows, doesn't show so much in DOS gaming but it's there (could be my card). Colours a bit dull especially whites. 60% rating
Jaton Video Magic 128 - Fine, no real issues, quite sharp at low res but not tested at high resolution. Colours look good, a bit less vibrant then the ET6100. 85% rating
Apocalypse 5D - Really nice, very sharp at low res and vibrant colours on par with Matrox at low resolutions. Should be the best at higher resolutions out of the three. 100% rating
I would place both the Tseng RAMDACs above your bog stand NVIDIA RIVA - GF3 partner boards and my ARK card a bit below.
Takeaways
I really wanted the ARK to do better it's still faster then most PCI cards and at 320x200 line doubled the lower dac quality is not that noticeable.
Get the ET6000 out of the three compared for PCI only DOS systems unless you want the rarity and just a slightly better visual quality of the ET6100 at a much higher cost.
Other PCI cards to be tested in the future 😀
