Re: Would Apple actually use the 970?

If they did, they would have to bump up everything else too? Something tells me that Apple would move up slowly just like everything else. maybe debut it at 1.6Ghz or maybe 1.8Ghz, I personally hope that I am wrong, but I don't think so.
What do you guys think?
The MHz to MHz raw benchmarks of a RIO-based 970 vs 7457-RM will be similar in most operations, with the lead in Floating Point going to the 970. The G4 will also cost a lot less and generate less heat than the 970.
Now when you put the chips behind an OS, HW, FSB, and design trade-offs in consumer vs. pro -- things will be a little different at similar clock speeds. Will be interesting to see if similarly equiped machines justify the differences in price.

The major speed impovements will be focused in bandwidth improvements in the system I/O and the bus -- not in the few extra MHz these machines generate.
It's all about how much data these machines can move, not how fast they vibrate, because even a single 500MHz G4 is capable of starving for data behind the 970s bus.
All the theoritical MIPs these high MHz CPUs can do, is meaningless unless there is actual data and instructions for the machine to work with.

The 7457-RM brings in a huge improvement in bus bandwidth, so these machines will most likely be a lot faster than the current crop -- even at similar clock rates.
The 970 won't be spectacularly faster than the 7457-RM, but will be able to work with MORE data. The 64-bit addressing will allow people to use far more than 2-4 GB of memory, work with far larger HDs and drive directories.
