PeterK writes "TG Daily has posted an interesting interview with Intel's top mobility executive David Perlmutter. While he sideswipes AMD very carefully ('I am not underestimating the competition, but..'), he shares some details about the successor of Core, which goes by the name 'Nehalem.' Especially interesting are his remarks about power consumption, which he believes will 'dramatically' decrease in the next years as well as the number of cores in processors: Two are enough for now, four will be mainstream in three years and eight is something the desktop market does not need." From the article: "Core scales and it will be scaling to the level we expect it to. That also applies to the upcoming generations - they all will come with the right scaling factors. But, of course, I would be lying if I said that it scales from here to eternity. In general, I believe that we will be able to do very well against what AMD will be able to do. I want everybody to go from a frequency world to a number-of-cores-world. But especially in the client space, we have to be very careful with overloading the market with a number of cores and see what is useful."
