NVIDIA's GA104 GPU uses the Ampere architecture and is made using a 8 nm production process at Samsung. With a die size of 392 mm² and a transistor count of 17,400 million it is a large chip. GA104 supports DirectX 12 Ultimate (Feature Level 12_2). For GPU compute applications, OpenCL version 2.0 and CUDA 8.5 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 6144 shading units, 192 texture mapping units and 96 ROPs. Also included are 192 tensor cores which help improve the speed of machine learning applications. The GPU also contains 48 raytracing acceleration cores.
