Comparison of PPC processors is a really open (and hard) discussion ... To be short, the pure CPU power will be lower than a G3 but if you compare a G3 AmigaOne with a Sam, other parts of the board give at the end the same global feeling of power. Faster memory, SATA, ... the CPU does not do all in a computer.
That's hard to compare CPUs, even with benchmarks. They all have differences that will make them better in some cases. You can find the result of nbench between several PPC boards but nbench is old and not well designed for modern CPUs. It just gives an overview ... and even strange results sometimes.
I have a non-Flex 600MHz board, and a 800MHz AmigaOne. Whilst the SAM was noticeably slower to start with, after I'd sorted my configuration out it doesn't seem any difference in everyday use.
There are times when the speed of the SAM's CPU really shows though, for example when compiling, or simply launching dynamically-linked executables.
If you've not used a faster one then I doubt you'll even realise unless you're doing really processor-intensive tasks.
@ice2642 Amiga Future magazine have done speed tests, and found that a 667MHz Sam had about the same performance as a 600MHz microAmigaOne (G3 of course).
Regarding speed comparisons, remember than until the OS4.1 Quickfix from Hyperion, OS4.1 on Sam440 was always using the (slower) debug kernel. Thus direct comparisons with any hardware were not a good idea.

I should have said the same **CPU** performance. The SATA HD, graphics & memory performance is of course MUCH MUCH faster, and in general usage more than compensates for the alledgedly slow CPU.
The CPU is not so power, but the all system use best the CPU and controlers, and all componentes and make a good performance.
It can be.
just for example.
Just remember the amiga classic A500 vrs a DX486, the 486 CPU is much more power than a motorola 68000, but the amiga 500 is more fast to day to day use and much other tasks than a 486.
