"Not that anybody on this thread gives a damn ... but I got an interesting email today from a developer who has a MP8641D dev kit. I have ars testbench 2.0 data now for MPC8641D, at 1.8 Ghz. On almost everything it is outrunning the dual (not dualcore) 1.8 970. On branchy scalar integer tests and on pseudo-random access tasks it is killing the 970. The bench doesn't directly measure latency, but the memory controller must be good and the bench numbers look "opteronish" in the way they scale with task footprint and from single-thread to dual. On latency-dependent dual-thread tasks significantly larger than Core1 caches ... it's beating core1 handily.

Single-thread FP is well down from 970 and moreso from Core1, no surprise.

It's a very potent altivec machine... beats everything except the dual-dual 970MPs running four threads. However most of the altivec in the testbench is well-optimized "

I would buy one, immediately. Also a PWRficient, but the 8641D is available, now
