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:
|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.
