After upgrading the desktop video cards range with the GEFORCE GTX 680, NVIDIA has announced a line of mobile graphics cards GeForce 600M. Usint the architecture Kepler, designed for laptops, we are familiar with the example of Acer laptop .
The GeForce 600M graphics processor with a new architecture - GK107, produced on 28 nm technology, 384 core CUDA, 16 blocks ROP, 64 texture units and has 128-bit bus to access memory. Like its close relative, GK104 , the GPU has the support of API DirectX 11.1, the smoothing algorithm TXAA, the mechanism of dynamic overclocking GPU Boost. In addition, GK107 supports useful for mobile computing technology NVIDIA Optimus.
Formally, the presented line of accelerators can be divided into three classes. Enthusiasts:
