NVIDIA GeForce GTX 650M, 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 by TSMC (Taiwan Semiconductor Manufacturing Company). 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 735MHz. The optional Turbo Mode can increase that frequency by a potential 22-23%, up to 900MHz, based on the laptop’s cooling capacity.
The chip also has a 128bit bus and is available in several models with DDR3 or GDDR5 memory. NVIDIA GeForce GTX 650M supports SLI, DirectX 11.1, Pixel Shader 5.0, SLI, Optimus, PhysX, OpenCL, OpenGL 4.1, DirectCompute, CUDA, 3DTV Play and 3D Vision. Memory bandwidth goes up to 80GB/sec. Max resolutions (WxH) are 3840×2160 digital and 2048×1536 analog.
