NVIDIA GeForce GTX 670M, codenamed “N13E-GS1-LP”, is a high-end graphics chip, announced in late Q1 of 2012. It is part of the Fermi generation and relies on a GK104 core, constructed through a 40nm process. Officially, it has 384 smaller shader cores, known as CUDA, but since GTX 670M is actually a modified GTX 675M, it can only make use of 336 CUDA cores.
All of them operate at 598MHz. 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 670M supports DirectX 11.0, Pixel Shader 5.1, Optimus, PhysX, OpenCL, OpenGL 4.1, DirectCompute, CUDA, 3DTV Play, 3D Vision and FXAA. Memory bandwidth is 72GB/sec. Max resolutions (WxH) are 2560×1600 digital (through HDMI) and 2048×1536 analog.
