Intel announced its 'Silverthorne' processor's brand, Atom, last month and today it completed the picture with speeds and feeds details of what is physically smallest CPU the company's ever made.
The Atom line-up comprises five CPUs all with 512KB of on-die L2 cache. The 800MHz Z500 and 1.1GHz Z510 both sit on a 400MHz frontside bus, while the 1.33GHz Z520, 1.6GHz Z530 and 1.86GHz Z540 have 533MHz FSBs. The latter incorporate HyperThreading, as expected, but the 400MHz FSB Atoms do not. All of them support SSE 3 instructions.
The Z500 has a TDP of 0.65W; the Z540's is 2.2W. All the processor in between these two are rated at 2W. In practice, that translates to average power consumption scores of 160mW (Z500) and 220mW (Z510 to Z540).
