NVIDIA GeForce 830M, is a lower-mid-range graphics chip, announced in Q1 of 2014. It is part of the Maxwell generation and relies on a GM108 core, constructed through a 28nm process. It consists of two shader blocks, known as SMM, and each of those has 128 smaller shader cores, also known as CUDA, for a total of 256 CUDA cores. The package also includes 16 texture cores and 8 raster cores.
All of them operate at 1082MHz, but NVIDIA’s GPU Boost 2.0 can increase that frequency based on the laptop’s cooling capacity.
The chip also has a 64bit bus and DDR3 memory. NVIDIA GeForce 820M supports DirectX 11.2, Pixel Shader 5.0, Optimus, SLI, PhysX, OpenCL 1.1, OpenGL 4.4, DirectCompute and CUDA. Memory bandwidth goes up to 14.4GB/sec. Maximum resolution (WxH) is 4096×2160.
