Tech Report har målt strømforbruget for Athlon 64 3500+ med 90nm teknologi, og sammenlignet med 130nm versionen og Pentium 4 3.4 GHz. AMDs nyeste har klart det laveste strømforbrug, forskellen når man kigger på hele systemet er op imod 100 Watt.
I also took some quick temperature readings, and I'll give them to you, although I wouldn't recommend taking them as gospel. The ambient temperature in my office was about 85F/29C, and it probably varied a bit during the duration of the tests. The test rig was on an open bench and was equipped with a stock AMD CPU cooler. I recorded temps at idle and under load via the Asus Probe utility, with the Folding@Home client providing the CPU loads. The 130nm Athlon 64 idled about 49C, and it ran up to 61C after ten minutes of number crunching. The 90nm version's idle temp was 41C, and it peaked at 55C under load. All in all, a good performance from the new 90nm AMD chip. Læs mere her: http://techreport.com/onearticle.x/7417
