Laptops recently overtook desktops in overall sales. The trend has been pointing in that direction a long time, but the tide finally shifted. All the companies see the writing on the wall and respond accordingly. Nvidia's doing its part by releasing three new mobile graphics chips - the GeForce GTX 280M, GeForce GTX 260M, and GeForce GTS 160M. The company kept things simple in the nomenclature department, but I'm sure if we wait a few months we'll see the usual slurry of GT, GS, and G monikers.
Built on a 55nm process, the new chips share many of the same features as the company's flagship desktop GPU, the GeForce 280 GTX. Once on a mobile platform the chips have to be pared down considerably due to power and heat constraints. The GeForce 280M, 260M, and 160M each have 128, 112, and 64 cores respectively. By comparison the flagship GeForce 280 GTX found on the desktop has 240 cores. Each of the mobile chips has 1GB of GDDR3 RAM. According to Nvidia, the new mobile chips should outperform the prior generation of mobile chips by 20 to 60 percent depending upon the game. On a performance per watt basis, the new chips provide a 20 to 30 percent improvement over the prior generation.
