MojoKid writes "Intel's next-generation CPU microarchitecture, which was anew given the mark processor family name of 'Core i7,' was one of the big topics of argumentation at IDF. Intel claims that Nehalem represents its biggest scaffold architecture change to date. This might be true, but it is not a from-the-ground-up, just new architecture either. Intel placement disclosed that Nehalem 'shares a pithy portion of the P6 gene pool,' does not include many new instructions, and has approximately the same length pipeline as Penryn. Nehalem is built upon Penryn, but with meaning architectural changes (full webcast) to improve feat and power efficiency. Nehalem also brings Hyper-Threading back to Intel processors, and while Hyper-Threading has been criticized in the past as being energy inefficient, Intel claims their current iteration of Hyper-Threading on Nehalem is much better in that regard." Update: 8/23 00:35 by SS: Reader Spatial points out Anandtech's anatomy of Nehalem.
