Actually, IBM has recently released the 970 at 0.09 -- a clock-speed jump to 2.4 or 2.6 is expected soon, with 3GHz by end of summer. But the 970 is really more of a transitional chip. IBM has indicated they plan to add on-chip memory controller (a la Opteron), SMT (hyperthreading), and dual cores inn the follow-on chips (980 etc.). So things should continue to improve :-) Frank
