NVIDIA GeForce GTX 670MX, codenamed “N13E-GR”, is a high-end graphics chip, announced in early Q4 of 2012. It is part of the Kepler generation and relies on a GK104 core, constructed through a 28nm process. It consists of five shader blocks, known as SMX, and each of those has 192 smaller shader cores, also known as CUDA, for a total of 960 CUDA cores.
All of them operate at 600MHz. NVIDIA has not included the Turbo Mode option, which can normally increase that frequency based on the laptop’s cooling capacity.
The chip also has a 192bit bus and is available in several models with GDDR5 memory. NVIDIA GeForce GTX 670MX supports SLI, DirectX 11.1, Pixel Shader 5.1, Optimus, PhysX, OpenCL, OpenGL 4.1, DirectCompute, CUDA, 3DTV Play, 3D Vision, TXAA and FXAA. Memory bandwidth goes up to 67.2GB/sec. Max resolutions (WxH) are 2560×21600 digital and 2048×1536 analog.
