Nvidia has quietly a few gpus in the GeForce 600M-line to its range. It comes to existing low-end models that of a new name. AMD is about to do the same with Radeon 7000M-videochips.

Nvidia has, as expected, the three ‘new’ notebook-gpus on his site. It comes to the GeForce GT 610M, 630M and 635M, which is for entry-level, basic, and mainstream notebooks are meant to be. The specifications are identical to that of the GeForce 520MX, 540M, and 555M. Seems the naming convention to indicate that the positioning changes and the gpu is possible in cheaper notebooks than is now the case. The first 28nm-gpus based on the upcoming Kepler architecture from Nvidia will be not earlier than the first quarter of 2012 is expected.

While competitor AMD still nothing on his site, claims to Anandtech that the manufacturer is on the verge of some low-end and mainstream gpus in a new name. At AMD would be Radeon HD 7400M-, 7500M -, and 7600M-gpu’s go. Other than at the end of november, the message goes not only to the low-end. Reason is according to Anandtech that the yields of TSMC’s 28nm production is still not good enough for mass production and AMD is yet obliged with a new line for the next generation of notebooks. Not all details of the new Radeon 7000M are known so it is not clear whether AMD the clock speed to be increased and whether all specifications are correct.
