NVIDIA GeForce GT 620M, codenamed “N13E-GE2” is a mid-range graphics chip, announced in late Q4 of 2011. It relies on a GF116, GF108 , GF106 or GF 104 core, which are constructed through a 28nm process.
All of them operate at a base 672MHz and there is no boost option here. Normally NVIDIA’s Turbo Mode can increase the clock frequency by, if the laptop cooling allows it. The GF116-based model is also available in 735MHz.
The chip comes in several versions with DDR3 memory. NVIDIA GeForce GT 635M supports DirectX 11.0, Pixel Shader 5.0, Optimus, PhysX, OpenCL, OpenGL, DirectCompute 2.1 and CUDA. Memory bandwidth goes up to 14.4GB/sec for the 128bit and 43.2GB/sec for the 192bit models. Max resolutions (WxH) are 2560×1600 digital and 2048×1536 analog.
