Message Text: NVIDIA has added three new high-performance mobile GPUs to its lineup, the GeForce GTX 680MX, GeForce GTX 675MX, and GeForce GTX 670MX.

Starting from the high-end GTX 680MX, it is based on the 28nm GK104 GPU and is Nvidia's most powerful GPU for notebooks. It features 1536 CUDA cores, with the same 720 MHz clock speed and 5 GHz memory. The GTX 680MX has also 2GB of GDDR5 memory.



The GTX 675MX is also based on the GK104 silicon, but has 960 CUDA cores, and 2GB of GDDR5 memory. The core is clocked at 600 MHz and the memory at 3.60 GHz.

Finally the GTX 670MX is based on the 28 nm GK106 silicon. It is configured with 960 CUDA cores but has a narrower 192-bit memory interface. Its core is clocked at 600 MHz and its memory at 2.80 GHz.
