The Heatsink Guide heeft ergens wat info over de warmte produktie van de Athlon vandaan weten te halen. 50W voor de 600Mhz versie, best wel heftig:
The K7 (sorry: Athlon) is about to become available... According to the first benchmarks being published, the performance will be great, and it will also be cheaper than comparable Intel CPUs. But what about power consumption?
The 500 MHz Athlon will consume between 25-40W, the 550MHz version about 45W. That's quite a lot, but still not unusual - remember that the first P2-300s from Intel consumed over 43W.
As for the higher-frequency versions: the 600 MHz Athlons will gobble up 50W, and the 700 MHz unit (which will be available later) will consume up to 60W. Note that all these values posted here are not "official" data - consider them as rumors, I can't guarantee that they are correct. I don't know if we'll really see 60W PC CPUs: Maybe the 700MHz Athlon will only be available after the die shrink to 0.18micron.
