AMD Instinct MI200 Accelerator gets 128 GB of HBM2e memory

AMD's next-generation AMD Instinct (MI-Next) computing gas pedals will feature unprecedented memory capacity & ; up to 128 GB per GPU. The announcement was made during the ISC 2021 HPC event, where Pawsey CTO Ugo Varetto talked about Setonix supercomputer specs.

The supercomputer, made possible by a $70 million investment, will allow Pawsey to improve the speed and processes of processing, data visualization and help improve other information operations. Processing large arrays will require both large amounts of memory and powerful graphics processors to increase system efficiency. The system will get more than 200,000 AMD Milan processor cores (Zen 3 architecture) as well as more than 750 AMD MI-Next compute gas pedals. The flagship Model of the MI-Next series, namely the Instinct MI200 will be the fastest performance gas pedal produced by AMD to date. The GPU, codenamed Aldebaran, has an MCM layout, meaning it combines multiple crystals on a single substrate. According to Pawsey, the GPU has 128 GB of HBM2e memory & ; four times more than the current Instinct MI100 gas pedal. The network has already published visualization of the circuit GPU MI200 c eight HBM2e memory stacks, associated with both crystals of the GPU:

AMD still hasn't confirmed the MI200 gas pedal specifications, but judging from the leaks, the full Aldebaran variant will have 128 compute modules, which means there are 8192 stream processors. The number of active modules in the MI200 is not yet known, but it is likely that a full GPU will be used here.
