Sarmad, Otellini claimed that SOI adds thermal resistance, leading to unreliability and forcing lower frequencies and performance. Well, check out the power graphs near the end of Anand's review here: anandtech.com Especially at idle (remember Pete's "substrate leakage") or at full load, the AMD system has lower power consumption despite higher performance in the benchmarks and higher CPU frequency, completely destroying Otellini's arguments. These are 90nm CPU chips, but Anand reported that the 65nm chips are even more power efficient. If the chip itself uses 10% less power, then a 1% thermal resistance differnce (i'm being generous) -- is immaterial. Petz
