Killer Instinct: AMD’s Multi-Chip MI200 GPU readies for a major global debut

AMD’s next-generation supercomputer GPU is on its way – and by all appearances, it’s about to make a name for itself. The AMD Radeon Instinct MI200 GPU (a successor to the MI100) will, over the next year, begin to power three massive systems on three continents: the United States’ exascale Frontier system; the European Union’s pre-exascale LUMI system; and Australia’s petascale Setonix system. The new GPU – which began shipping to its first customers this summer – is based on AMD’s CDNA2 architecture and, unlike the PCIe MI100, uses a mezzanine form factor (akin to the SXM versions of Nvidia’s V100 and A100 GPUs). The MI200 will sport two dies – each rumored to have 110 compute units – connected via a passive interposer die, and up to 128GB of HBM2E DRAM. The MI200 is anticipated to deliver at least twice the performance of the single-die, 11.5-teraflops MI100, which had 120 compute units and 32GB of HBM2 memory. The MI200 will certainly be the first multi-chip module (MCM) GPU from AMD and also looks poised to be the first MCM GPU on the general market. AMD’s highest-profile customer for the MI200 might also be the first to launch: just a few weeks ago, it was revealed that the exascale Frontier supercomputer is undergoing installation at Oak Ridge National Laboratory (ORNL), with that installation scheduled to complete sometime this year or early next year.
