Gamers.nl schrijft: "Australianit.com.au heeft de beschikking gekregen over een P4 met alles erop en eraan. Na uitvoerig testen blijkt dat de P4 slecht presteert in vergelijking met de huidige generatie processoren. Het kraken van rc-64 blokjes is zelfs rampzalig, een Athlon 800 is 1.5x zo snel dan een 1.5 GHz P4.":
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 Optima 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 is at the moment a really bad choice.
