GPUs are generally much more flexible and can run something resembling a normal C program. From the little public information available chips like Google TPU or NVIDIA's Tensor Core (a functional unit on the Volta architecture) are essentially hard-wired to do exactly low precision matrix multiplication. Less flexible but more efficient when you know that's what your workload is. https://devblogs.nvidia.com/parallelforall/inside-volta/ https://devblogs.nvidia.com/parallelforall/inside-volta/ https://www.nextplatform.com/2017/04/05/first-depth-look-googles-tpu-architecture/ https://www.nextplatform.com/2017/04/05/first-depth-look-goo...
