Rather than guessing why not perform some benchmark tests between your 800 MHz Efika MX and an 800 MHz Sam440? I'd be interested in the results. But mind you, the Cortex-A8 is just an in-order execution core whereas the PPC440 can operate out-of-order.

Of course. Current PPCs scale from as low as 40 MHz ;-)

THTF/MTC ceased production of LimePC devices based on PPC? I ask because they still offer those in their web stores:
