NVIDIA on Wednesday formally introduced GeForce 600M notebook graphics with what's now known to primarily be a respin of the 500M series. The 610M, 630M, and 635M are all parallels to the 520MX, 540M, and 555M, but all edged down in the lineup to be considered more affordable parts. The 635M does get an upgrade in support for faster 3.6GHz equivalent GDDR5 memory, giving it a higher 57.6GB per second of bandwidth over the 555M's 50.2GB.
