Which means that on a 50 MHz bus you could still get 1 GHz on the CPU. I'm not sure how much performance you'd lose with such a high multiplier. Because our S900s tend to go up to about 60 MHz bus speed most of the time, you could probably do a 17X bus multiplier and something like a 59 MHz bus speed and still get 1 GHz. Further, IBM has put the 512KB L2 cache on the chip, so there's no need for separate cache chips (saves a little money in assembly) and the L2 cache runs full speed at the same speed as the CPU. The disadvantage is that it's only 512KB and not 1 MB as most mid to high end upgrades are these days. I'm really drooling for an upgrade maker to stick this thing on a ZIF. If I can figure out how to get my hands on a sample, I may buy a used 233 or 266 Apple ZIF and see if I can rip off the old chip and solder down one of these new ones. Mad Dog, you ever have any luck soldering on BGAs? Actually, I'm not yet sure the thing is pin compatible with older CPUs. IBM doesn't appear to have a data sheet on their site, only marketing type stuff so far. Odd, since they claim it's sampling in early 2002.
