Intel doesn't pull the curtain back on Sandy Bridge until next month, but production on products has been underway for a little while now and various products are leaking out with the new chips inside.
Enter, Alienware M17x. Benchmarks are looking good with 3DMark 06 results showing 2GHz Core i7-2630QM machine running Intel's integrated graphics scored 15,940, while a 2.2GHz i7-2720QM with AMD Radeon HD 6900M graphics scoring 20,155 marks, and a 2.3GHz i7-2820QM chip paired with a GeForce GTX 460M GPU did 16,957.
It looks like Intel's integrated graphics are finally improving - does anyone remember the Intel i740? I sure do, the days of the critically-lauded Trespasser with near-perfect (at the time) physics.
