AMD Radeon Instinct MI100 ‘CDNA GPU’ Alleged Performance Numbers Show Its Faster Than NVIDIA’s A100 in FP32 Compute, Impressive Perf/Value
Alleged performance numbers and details of AMD’s next-generation CDNA GPU based Radeon Instinct MI100 accelerator have leaked out by AdoredTV. In an exclusive post, AdoredTV covers performance benchmarks of the upcoming HPC GPU against NVIDIA’s Volta and Ampere GPUs.

AdoredTV claims that the slides they have received are from the official AMD Radeon Instinct MI100 presentation. The ones posted on the source seem to be modified versions of the original ones but details are kept intact. In our previous post, we confirmed that the Radeon Instinct MI100 GPU was on its way to the market in 2H 2020. The slides from AdoredTV shed some more light on the launch plans and server configurations that we could expect from AMD and its partners in 2020 & beyond.
AMD Radeon Instinct MI100 1U Server Specs
First up, AMD is planning to unveil an HPC specific server which would feature 2P design with dual AMD EPYC CPUs that could either be based on the Rome or Milan generation. Each EPYC CPU will be connected to two Radeon Instinct MI100 accelerators through the 2nd Generation Infinity Fabric interconnect. The four GPUs will be able to deliver a sustained 136 TFLOPs of FP32 (SGEMM) output which points out to around 34 TFLOPs of FP32 compute per GPU. Each Radeon Instinct MI100 GPU will have a TDP of 300W.
Additional specifications include total GPU PCIe bandwidth of 256 GB/s which is made possible on the Gen 4 protocol. The combined memory bandwidth of the four GPUs is at 4.9 TB/s which means that AMD is using HBM2e DRAM dies (each GPU pumps out 1.225 TB/s bandwidth). The combined memory pool is 128 GB or 32 GB per GPU. This suggests that AMD is still using 4 HBM2 DRAM stack technology and each stack housing 8-hi DRAM dies. It looks like XGMI won’t be offered on standard configurations and will be kept limited to specialized 1U racks.
