NVIDIA's GA102 GPU uses the Ampere architecture and is made using a 8 nm production process at Samsung. With a die size of 628 mm² and a transistor count of 28,300 million it is a very big chip. GA102 supports DirectX 12 Ultimate (Feature Level 12_2). For GPU compute applications, OpenCL version 2.0 and CUDA 8.6 can be used. Additionally, the DirectX 12 Ultimate capability guarantees support for hardware-raytracing, variable-rate shading and more, in upcoming video games. It features 10752 shading units, 336 texture mapping units and 112 ROPs. Also included are 336 tensor cores which help improve the speed of machine learning applications. The GPU also contains 84 raytracing acceleration cores.
