Dan's the man!
<< The P4's performance with the distributed.net client ? one of the world's leading suckers up of otherwise unused CPU cycles ? was appallingly bad. My 800MHz Athlon crushed the 1.5GHz P4 by 50% for RC5 cracking (trying to break a strongly encrypted message by brute force) and by 20% for OGR (finding Optimal Golomb Rulers, a task which is actually somewhat useful).
A 400MHz P-II managed almost exactly half of the P4's scores. None of the six RC5 cracking cores suited the P4 at all. It just stank. Intel are selling Celerons at the moment that do better.
Presumably, a P4-optimised RC5 core for the distributed.net software will come along shortly, and perhaps there'll be an update for the OGR side as well. If you're trying to look studly in the distributed.net rankings, though, the P4 would at the moment seem to be a really bad choice.
>>
The NDA's are over.... should be lots more P4 reviews coming very shortly.
edit: Ack! Didn't notice BK had already posted Anand's benchmarks.
