Yea they have different CPUs, I mentioned this earlier (page 26 I think). Software written for the 6700 and earlier won't scale or change CPU's in the 68800 and later. Far as I know there is still no software to change the CPU speeds in the 6800+ CPUs. If it makes you feel any better, my qwest apache is plain slow compared to my sprint apache, both run stock carrier roms, it's just slower, it could just be your build is faster and that is what you are seeing.

You can also benchmark with TCPMP, though it would require a before and after benchmark of the different roms, meaning benchmark a file on your upgraded, then flash back to your stock, using the same file in the same manner (phone or sd memory) and you may get a slight difference in speed. There is variation from run to run anyways, keep that in mind. Best way is to run 3 each, and use the averages to determine if any actual increase is there.
