NVIDIA GeForce GTX 880M, codenamed “N15E-GX-A2”, is a high-end graphics chip, announced in Q1 of 2014. It is part of the Kepler generation and relies on a GK104 core, constructed through a 28nm process. It consists of eight shader blocks, known as SMX, and each of those has 192 smaller shader cores, also known as CUDA, for a total of 1536 CUDA cores. The package also includes 128 texture cores and 32 raster cores.
All of them operate at 954MHz, but GPU Boost 2.0 can increase that frequency based on the laptop’s cooling capacity.
The chip also has a 256bit bus and GDDR5 memory. NVIDIA GeForce GTX 880M supports DirectX 11.0, Pixel Shader 5.0, Optimus, SLI, PhysX, OpenCL 1.1, OpenGL 4.4, DirectCompute, CUDA, Direct Compute and Blu-Ray 3D. Memory bandwidth is 160GB/sec. Max resolutions (WxH) are 3840×2160 digital and 2048×1536 analog.
