NVIDIA GeForce GTX 660M, codenamed “N13E-GE”, is a mid-range graphics chip, announced in late Q1 of 2012. It is part of the Kepler generation and relies on a GK107 core, constructed through a 28nm process. It consists of two shader blocks, known as SMX, and each of those has 192 smaller shader cores, also known as CUDA, for a total of 384 CUDA cores.
All of them operate at 835MHz. 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 128bit bus and is available in several models with GDDR5 memory. NVIDIA GeForce GTX 660M supports SLI, DirectX 11.1, Pixel Shader 5.0, Optimus, PhysX, OpenCL, OpenGL 4.1, DirectCompute, CUDA, 3DTV Play and 3D Vision. Memory bandwidth goes up to 64GB/sec, while texture fill rate is 30.4 billion/sec. Max resolutions (WxH) are 3840×2160 digital (through HDMI) and 2048×1536 analog.
