[Ti] New 15" 1.25 GHz PowerBook

[Chris Rock]

it was 256k l2 and 1mb L3, now it is 512k L2

L2 runs at core speed, L3 ran at a divider of core speed.

Has nothing to do with the system bus, as they are both on die ( on the 
cpu ) all transactions were done inside the cpu, hence the reasoning for 
a  L2 or L3 in the first place, to reduce the cpu from having to hit 
main memory as much for reused information.
