I've been playing with the Vortex86 range of processors from DM&P for nearly 15 years, initially as a proto-raspberrypi running linux, and more recently as an ultra-portable DOS gaming platform. For a currently-manufactured chip it has a number of super useful features for a modern DOS gaming platform like arbitrary CPU clock division, the ability to boot from SD cards, and full access to the ISA bus for soundblaster compatibility. I've used it in a couple of builds, e.g. - Tiny Vortex86-based DOS gaming PC - weeCee

Over the years I've acquired quite a few Vortex86-based SBCs so I thought it would be fun to run them through Phil's dosbench suite. I also took current readings using a Fluke 87III, although that isn't a super fair test because the boards all have slightly different peripherals on them.

Unfortunately, a lot of the results aren't terribly meaningful on faster processors like these, and many also test VGA performance at the same time. Any advice on other benchmarks I could run would be very helpful.

I think Windows 98 should run on all of these boards so if there is more appropriate benchmarking software there then I might try that too. Linux is also very much an option.

Anyway - the boards tested were :

ICOP-6070 -- PC/104 (OG Vortex 86)
VSX-6154-V2 -- PC/104 (Vortex86SX)
Ebox 3350MX -- Thin Client (Vortex86MX)
SOM304RD52VINE1 -- SoM (Vortex86DX)
Ebox 3350DX2 -- Thin Client (Vortex86DX2)
SOM128EX -- SoM (Vortex86EX)

Clearly the Vortex86MX is the best because it gets a DOOM score of 1337.

Here's what the various CPU identification outputs looked like :

If anyone has any more ideas of tests I could run on these things I'd be very eager to experiment.
