Improvement in the frequency potential and energy consumption level in four core 45 nm intel processors are connected with passage on C1 and M1 stepping .
From the official information (60 KB) . On 13 October will appear the four core processor 45 nm processors xeon stepping E0. Then later dual core processors xeon (Wolfdale) will also pass on E0 stepping .
New stepping will require a BIOS update. CPUID Value will change from 0x1067A to 0xA005b013. Four core processor xeon x5482 (3.2 GHz) will get the lowered TDP value from 150 to 120 W. Consequently, we can expect improvement in the thermal and energy characteristics .
