Confirming something that we had already seen hints of, Intel has announced that it is looking forward to quad core laptops hitting the scene throughout 2008. Mooly Eden, GM of Intel's mobile platform group, said that we won't see these quad cores in business class laptops for a while, even being honest enough to admit that there aren't enough multi-threaded applications out there to justify it. In practically the same breath, PC World mentions that the chip will target high-level gaming laptops, which is cool because gamers will no doubt lap the new chips up: even if gaming is for the moment a very much single-threaded activity. Architecturally the new chip will have to differ from Intel's current offerings such as Santa Rosa, so you can probably expect to pay quite a premium until they hit the mainstream. (Not that you didn't know that already.)
P.S. Bonus points for most imaginative insult in response to the fatal mistake of using Apple's Intel logos to illustrate this post.
