Inside Intel's Core i7 Processor, Nehalem

Posted by Soulskill on from the upgrades dept.

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.

    Meh. I'm still waiting for multicore quantum computing. Or at least something that can execute code that doesn't exist yet, so i can play Duke Nukem Forever. Actually, what I really want is a processor that can execute code by its spirit, rather than its letter, so buggy code will work correctly anyway. :-)

      You probably also want a user interface that does what you mean, not what you said.

    Is it 3.999999999 more accurate?

    I'm pretty sure the parent post was written by a machine. Turing test: failed.

    So, you're saying that Intel is also supplying marijuana with these systems?
