Nvidia announces GeForce 600M mobile GPUs

The GeForce GTX 680 isn't the only new GeForce to break cover today. Nvidia has also announced a whole family of GeForce 600M-series graphics processors, which includes nine offerings meant to service everything from mainstream laptops to high-end gaming notebooks.

Here's a quick, at-a-glance look at the new parts, based on Nvidia's specs:

Model ALUs Core
clock (MHz)
fill rate
bus width
GeForce GTX 675M 384 620 39.7 256 GDDR5 96.0
GeForce GTX 670M 336 598 33.5 192 GDDR5 72.0
GeForce GTX 660M 384 835 30.4 128 GDDR5 64.0
GeForce GT 650M 384 735/850 up to 27.2 128 GDDR5/DDR3 up to 64
GeForce GT 640M 384 up to 625 up to 20.0 128 GDDR5/DDR3 up to 64.0
GeForce GT 640M LE up to 384 up to 500 up to 16.0 128 GDDR5/DDR3 up to 28.8
GeForce GT 635M 96/144 up to 753/675 up to 16.2 up to 192 GDDR5/DDR3 up to 43.2
GeForce GT 630M 96/144 up to 672/525 up to 12.6 128 DDR3 up to 28.8
GeForce GT 620M 96 up to 625 up to 10.0 up to 128 DDR3 up to 28.8
GeForce 610M 48 up to 900 up to 7.2 64 DDR3 up to 14.4

Oh, and Nvidia says the GeForce GTX 675M, GTX 670M, and GTX 660M support two-way SLI configs.

Yeah, so, there's a fair amount of flexibility with a number of those models. Some can have varying clock speeds, different memory types, and presumably variable performance depending on the configuration. The high-end flavors look reasonably consistent, though. Also, as always, it's not entirely clear which parts truly warrant the 600M label and which ones might be re-purposed GPUs from prior generations.

"Many OEMs" already offer 600M-series GeForces in Sandy Bridge notebooks, according to Nvidia. The company adds, "Once Intel's next-generation platform is fully rolled out, you’ll find incredible new notebooks with our GPUs being offered by every major manufacturer." Those manufacturers will apparently include Acer, Alienware, Asus, Dell, Gigabyte, HP, Lenovo, MSI, Samsung, Toshiba, and Vizio.
