Nvidia quietly introduces GeForce 600M series

Without even a press release Nvidia has introduced the GeForce 600M series. But for anyone expecting something new there is disappointment for the time being. The initial launch of the 600M series will be based off old 40nm GPUs rebranded as ‘new’ GPUs. The naming scheme is done in a way so that if a user was to upgrade forward in series, i.e. from a 550M to a 650M, they wouldn’t end up buying the same re-branded GPU as the GT 550M is rebranded as a GT 635M which is much lower down. The ‘new’ 600m GPUs include the GeForce GT 635M, GT 630M and 610M.

The GT 635M is the fastest piece of the initial GeForce 600M series. The GT 635M comes in two versions because of the fact it is based off both the GT 555M and GT 550M. The first variant has 144 CUDA Cores (clocked at 1350 MHz) and a 192-bit memory interface whilst the second slower variant has 96 Cores (clocked at 1506 MHz) on a 128-bit interface. The GT 630M has 96 Cores (clocked at 1344 MHz) across a 128-bit interface (making it simply a down-clocked GT 635M/GT 550M). Finally the entry level GeForce 610M  has 48 Cores (clocked at up to 1800 MHz) and a 64-bit interface.

All three cards are 3D Vision ready and feature support for DirectX 11, OpenGL 4.1, CUDA, PhysX, Optimus, OpenCL, and HDMI 1.4. Laptops equipped with these ‘new’ GeForce models are expected in 2012.
