NVIDIA GeForce GTX 780M, codenamed “N14E-GTX”, is a high-end graphics chip, announced on May 5, 2014. It is part of the Kepler generation and relies on a GK104 core, constructed through a 28nm process. GTX 780M has 1536 CUDA cores.
All of them operate at a base 823MHz and there is a boost option. Turbo mode can increase that if the laptop’s cooling capacity allows it.
The chip also has a 256bit bus and GDDR5 memory. NVIDIA GeForce GTX 780M supports SLI, DirectX 11.1, Pixel Shader 5.0, Optimus, PhysX, OpenCL, OpenGL 4.1, DirectCompute, CUDA, 3DTV Play and 3D Vision. Memory bandwidth is 160GB/sec. Max resolutions (WxH) are 3840×2160 digital and 2048×1536 analog.
