IBM claims massive power drop for 90nm G5

Unknown

IBM claim their latest G5 CPU cuts power consumption in half over that of previous chips.

[blockquote]You can see why Apple waited for the 90nm version of the PowerPC 970 before launching a G5-based Xserve 1U rackmount server: the latter's heat dissipation characteristics.

While Intel continues to have problems with the power consumed by its 90nm 'Prescott' processor - 100W at around 3.2GHz - IBM's own documentation claims the 90nm 970 eats 24.5W at 2GHz. By comparison, the 130nm 970, currently used by Apple in its Power Mac G5 desktop line, consumes 51W at 1.8GHz.

One crucial difference between IBM's processors and Intel's is the former's use of silicon-on-insulator technology, which undoubtedly helps reduce leakage at the smaller process.

That bodes well for AMD. Its 90nm processors are due later this year. Like the IBM chips, they too utilise SOI. IBM's success lends weight to the claim by American Technology Research analyst Rick Whittington that SOI will be crucial to AMD's transition to 90nm.

AMD Already (reportly in 11/03) has 90nm Opterons up and running1 These are the Bad Boys to wait for!
