Here’s the quote, straight from their press release: “Our peak rate of 270,147,024 kkeys/sec is equivalent to 32,504 800MHz Apple PowerBook G4 laptops or 45,998 2GHz AMD Athlon XP machines…”

To emphasize the point, it takes about 1.5 PCs to do the work of one Mac, even though they operate at very different clock rates.

Hmmm.

[UPDATE]: I’d like to point out a later story about color blindness and streetlights.
