New PB uses 7455 chip!

[powerbook]

It's amazing that apple has been able to use the same chip as in the desktops.

anyway, the full story/thread is here (to long to post here):

I almost wish...

...that they'd used the 7445 instead, then the fan would almost never come on. Still, the L3 cache helps *a lot* with Altivec. It was proved on the ArsTechnica forums that a 533MHz G4+ can saturate a 133MHz system bus with one well tuned Altivec algorithm (a G4+ can do 3 instructions per clock cycle, so an 800MHz one would need more than a 400MHz bus [probably closer to 600MHz] to keep up with it under ideal conditions). Cache helps a lot with that.

forget macgo - we've got our own forums right here!

anyway, allright! maybe the TiBook can be overclocked to 1GHz!
