I had a chance to run some benchmarks on the Orange Micro OrangePC 660 and PCfx!. I purchased a PCfx! which I returned for the OrangePC 660 and then upgraded with a AMD K6-2/400.
The Orange Micro PCfx! is simply the OrangePC 660 with the L2 cache removed and a fixed (not upgradable) IDT WinChip/200 processor. ZD WinBench 99 was used. CPUmark32 gives a good estimation of overall general Windows performance. FPUWinMark gives an idea of game computational performance. Neither benchmark can utilize the 3DNow! features of the AMD K6-2 which can additionally boost games that are optimized for it.

Overall almost 3 times better performance with OrangePC 660 K6-2/400 over PCfx! In gaming specific situations over 4 times better performance!
A K6-2 is 21% faster than the same speed WinChip. Double the internal processor frequency and it boosts performance by 30%. Add L2 cache and performance increases by a huge 50%! Running at 100 MHz bus instead of 66 MHz gives another 24% increase.
In floating point calculations the K6-2 is 100% faster than a WinChip! Double the internal processor frequency and it boosts performance by 97%.
A disappointed PCfx! user, but impressed OrangePC 660 user.
