While I doubt the report...(3.2GHz from 1.24 GHz is nuts) I do not doubt that the update did increased the performance of the console. The system is suspected of being under-clocked anyways (like most Nintendo systems) so a boost in clock speed is not that surprising. I however suspect a more realistic boost like to 1.5GHz to maybe even 2Ghz (at max) instead of the outrageous claim of 3.2GHz. Well it is a custom chip so no one can really say for sure. (The PPC 750 it's based on has no multi-core commercial variants so any comparison to them is moot).
