NVIDIA has released a new variant of its Volta-based Telsa graphics card known as the Tesla V100S. The new server aimed solution carries the same specifications of the full Volta GPU but offers a lot faster clock frequencies for both GPU and memory, driving its performance beyond 16 TFLOPs in single-precision compute workloads.

In terms of configuration, the Tesla V100S has the same GV100 GPU which is based on the 12nm FinFET process node. The specifications include 5120 CUDA cores, 640 Tensor cores and 32 GB of HBM2 memory. As you can tell, these are very similar specifications to the existing Tesla V100 but there are some significant changes made to both, the GPU and memory clock speeds.
