AMD has just announced its next-gen CDNA GPU-based Instinct MI100 accelerator, which packs 7680 stream processors, and 32GB of HBM2 with an ultra-fast 1.23TB/sec of memory bandwidth. Check it out:

Inside, the new Instinct MI100 accelerator is a 7nm CDNA GPU with 120 Compute Units, or 7680 stream processors. We've heard of this GPU before as it is codenamed Arcturus, powering the new Instinct MI100 accerlator. The GPU itself is clocked at around 1500MHz with 11.5 TFLOPs of FP64 performance, 23.1 TFLOPs of FP32 performance, and a huge 185 TFLOPs of FP16 performance.

AMD has used 32GB of HBM2 memory, where systems with 4 or 8 GPUs will use the new Infinity Fabric X16 interconnect with bandwidth of 276GB/sec. The HBM2 memory is capable of hitting up to 1.23TB/sec of memory bandwidth which is huge -- it doesn't quite compete with the 1.53TB/sec pumping away from NVIDIA's new A100 which uses HBM2e memory.
