NVIDIA GeForce GTX 860M Detailed
 

NVIDIA slipped out the first mobile GPU based on its GM107 silicon, the GeForce GTX 860M, which was spotted on the forumscape. The GTX 860M is configured identically to the desktop GTX 750 Ti, featuring the chip's full complement of 640 CUDA cores, 40 TMUs, 16 ROPs, and a 128-bit wide GDDR5 memory interface, holding 2 GB of memory. The core is clocked at 540 MHz, and the memory at 5.00 GHz (GDDR5 effective).

The mobile MXM card was put through a battery of synthetic tests, in which it was found to be twice as fast as its predecessor, the GTX 660M. In 3DMark 11 (performance preset), it scored P5339, compared to the P2563 points scored by the GTX 660M. In 3DMark 11 (extreme preset), the story is similar, with the GTX 860M scoring X1662, compared to the X774 scored by the GTX 660M.
