What do the CPU cognoscenti make of IBMs recent 970FX achievements?
IBM 90nm G5 chip to 'outrun' Prescott, Athlon 64
"IBM's technically as yet unannounced PowerPC 970FX has won the Microprocessor Report Analysts' Choice Award for Best Desktop Processor. And according to MR editor-in-chief Peter Glaskowsky, Intel and AMD had better watch out. The 970FX is the 90nm die-shrink of the original 130nm PowerPC 970, launched back in October 2002 and finally shipped last summer, most notably inside Apple's Power Mac G5.
IBM is expected to launch the 970FX formally next week at the IEEE Solid-State Circuits Conference (ISSCC), along with its PowerTune technology, which adds SpeedStep-style clock frequency scaling that can synchronise across multiple processors. The chip should be shipping very shortly. Apple's Xserve G5, which is based on the 970FX, is due to ship this month.
IBM documentation has already revealed the 970FX's impressive power characteristics: 24.5W at 2GHz. The 130nm 970, by contrast, eats up 51W at 1.8GHz."
This adds interest to a recent Anandtech thread on heat dissipation/power consumption (I quote):
G5 970FX 2GHz : 24.5W (normal load)
G4 1.33: 45 W (normal load)
G5 2GHz: 55 W (normal load)
Athlon XP 3200+: 77 W (Thermal Design Power)
Intel's 3.2GHz P4: 82W (Thermal Design Power)
Opteron 246 2.0: 84.7W to 89 W (different AMD sources) (Thermal Design Power)
Itanium 2 1.5 6M: 107 W (Thermal Design Power)
Xeon 3.2: 110 W (Thermal Design Power)
Outside the marketing hype what real world processing performance improvement are we likely to see?
Is G5 970FX 24.5W at 2GHz laptop feasible?
How does it compare with existing solutions?
