Added Atom330 and Q9550 (Intel CPUs) numbers.
TA-t3: I believe it's all integer. Seems like along time since anybody worked on the arm cores for distributed.net, the most modern one was X-scale (which would favour Sheeva).
pierro78: Well if you're going to crunch RC5 or OGR, sure. But in your hands the SmartQ7 "feels" 3 times slower than N800/N810.
Mandor: I am not that surprised. ARM's Cortex A8 is a big step up in performance. Though sheevaplug's kirkwood is supposedly dual-issue too. Maybe it's the branch prediction in A8 that helps it, who knows.
Matan: Tablet and SmartQ are ARMv6.
Besides, ARMv7 doesn't mean superscalar. The Cortex A8 ARMv7 implementation is, but snapdragon is a different implementation and will perform differently.
