AMD has finally announced the next-generation CDNA GPU-based Instinct MI100 accelerator. The company calls it the fastest HPC GPU in the world. It will be utilizing the CDNA architecture, which is different than the RDNA. The new architecture is specifically designed for the HPC segment.
The card will feature a 7nm CDNA GPU and packs 120 Compute Units or 7680 stream processors. The CDNA GPU powering instinct MI100 measures at around 720mm2. The GPU has a clock speed configured around 1500 MHz and delivers a peak performance throughput of 11.5 TFLOPs in FP64, 23.1 TFLOPs in FP32, and will feature a total power draw of 300 Watts. The card will come with 4 and 8 GPU configurations and a rated bandwidth of 276 GB/s.
With the new AMD Matrix Core technology, the MI100 also delivers a nearly 7x boost in FP16 theoretical peak floating-point performance for AI training workloads compared to AMD’s prior generation accelerators.
This new GPU from AMD does promise up to 2.1x more performance per dollar compared to the popular NVIDIA A100.
