Intel Penryn Processor is Ultra Power Efficient

Vigile writes: Intel is soon going to release the Yorkfield core Penryn-based processors for desktop users though performance previews are going to start coming out today. Among the interesting architecture changes include 12MB of L2 cache, SSE4 instructions and a brand new 45nm process technology. Of course the performance of the new CPU is better, but the most exciting news might be related to the power consumption: in several cases the quad-core processor reviewed today actually uses 50+ watts LESS power than Intel's previous top dual-core processors while performing 50% or more faster!
