Wow, this is good news. How about a new Peg with one of these and a 1.7GHz MPC7448! :shocked:
As for comparisons with the 8641/8641D. The 7448 and 8641 are both based on the PowerPC e600 core (or two of them in the D). But the 8641 has the advantage (?) of a much faster (integrated) MPX bus. I'm not a chip guy so on paper the 8641/8641D looks much better, but there are probably real world factors that affect it's actual performance/usability.
