NVIDIA GeForce GT 755M, codenamed “N14P”, is a high-end graphics chip, announced in late Q2 of 2013. 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. The package also includes 32 texture cores and 16 raster cores.
All of them operate at a base 980MHz and there is no boost option. NVIDIA has not included the optional GPU Boost 2.0 in the GeForce 7xxxM series. Normally, if the laptop’s cooling capacity allows for it, GPU Boost 2.0 can increase the clock frequency.
The chip also has a 128bit bus and GDDR5 memory. NVIDIA GeForce GT 755M supports DirectX 11.1, Pixel Shader 5.0, Optimus, SLI, PhysX, OpenCL, OpenGL 4.1, DirectCompute, CUDA, 3DTV Play and 3D Vision. Memory bandwidth is 86.4GB/sec. Max resolutions (WxH) are 3840×2160 digital and 2048×1536 analog.
