I just wonder why
arm v5(Sheevaplug 1.2 GHz)
fast than
both arm v7(omap 3420 cortex A8 600 MHz)
and arm v6(omap 2420 arm11 400 MHz)
frequency?
or
pi is not suit for performance test

The description for pi says it's limited only by your machine's ram. The SheevaPlug has half a gigabyte of fast ram.

is it possible to UPGRADE any of the hardware on the N900???
RAM - PROCESSOR - ECT ? ? ?

These results aren't making much sense..
SmartQ7, 667MHz s3c6410 ARMv6, original firmware 5.0

EDIT: Added intel Atom 330 and Intel Core 2 Quad 9550 CPUs.
Another benchmark, distributed.net OGR and RC5. Clients available for arm-eabi at distributed.net, ./dnetc -bench, take fastest result.
The results for the multicore hyperthreaded Atom330 and multicore Q9550 are for a single thread on a single core.
I hope the formatting remains sane. I found no proper way of making tables on the forum...
RC5-72
Interesting things:
N900 has 1.5 times the clockspeed of N800, yet it's over 2 times faster.
Sheevaplug has DOUBLE the clockspeed of N900, yet it's only 1.3 times as fast as N900.
OGR-NG:
The overall picture is the same, the N900's CPU does more work per clcok than all the other ARM cores. Interestingly, it's not far behind Atom here. Remember, that for decent battery life in a portable, the atoms usually run at 600-800MHz.. That puts them in an interesting position when compared to Omap3...
Core2 is brutal, but we knew that. And it gobbles up insane amounts of power to keep its 1 kilogram heatsink hot...

That makes sense, it's OMAP3 vs. OMAP2. The only surprise is that it isn't even faster. Was the N900 version compiled with options for the architecture?
Is there floating point involved? Double- or single-precision, if so?
