The GA102 is one of the many Ampere GPUs that we have seen in the high-end gaming segment and is so far the fastest gaming GPU that NVIDIA has produced. The GPU is based on Samsung's 8nm custom process node designed specifically for NVIDIA and features a total of 28 Billion transistors. It measures at 628mm2 which makes it the 2nd biggest gaming GPU ever produced right below the Turing TU102 GPU.
