Intel is announced that their research teams work on six core server CPU platforms based on 45 nm Penryn architecture. The new processors will have name Nehalem and will improve the performance and energy with new Simultaneous Multithreading (SMT) technology so each core would process two threads at a time, not alternately like hyperthreading but truthfully at the same time. Also the microarchitecture bent on delivering an 8 MB level-3 cache, DDR3-800 memory support, 25.6GB per second Quickpath interconnects, an integrated memory controller and optional integrated graphics to high-end servers and eventually laptops. First models are expected at the end of this year.
