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)	Texture fill rate (Gtexels/s)	Memory bus width (bits)	Memory type	Memory bandwidth (GB/s)
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.
