Inside Intel's Core i7 Processor, Nehalem
MojoKid writes "Intel's next-generation CPU microarchitecture, which was recently given the official processor family name of
'Core i7,' was one of the big topics of discussion at IDF. Intel claims that Nehalem represents its biggest platform architecture change to date. This might be true, but it is not a from-the-ground-up, completely new architecture either. Intel representatives disclosed that Nehalem 'shares a significant 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 significant architectural changes (full webcast) to improve performance 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 analysis of Nehalem.
Still, if one can safely enable hyperthreading without slowing down your system, unlike the last time we went through this, we should consider it a success.
Aye, I remember the joys of the first HT tick back when tom's hardware was a less cluster fuck of a webpage. I do remember intel saying that although it wouldn't be found on later chips they did in fact plan on using the technology in one for or another eventually.
