AMD’s new MI200 128GB GPU will power Setonix supercomputer
Pawsey’s new research supercomputer Setonix It will be equipped with AMD’s latest and greatest processing nodes, including AMD’s unannounced Instinct MI200 CDNA GPU, with 128 GB of HBM2E memory. Make Setonix the second supercomputer in the world equipped with AMD MI200 GPU.
This AMD hasn’t even released MI200 yet, But thanks to the leak of Linux drivers and the likes of Setonix and border, We now know the core details about AMD’s new enterprise GPU.
MI200, code-named Aldebaran, is expected to become the monster of GPU. It will use AMD’s latest CDNA2 architecture based on 7nm node and adopt a multi-chip design. The GPU will consist of two GPU chips connected to the AMD Infinity high-performance interconnect (think of it as AMD’s Infinity Fabric, but for GPUs).
What’s more special is that the GPU can run up to 128 GB of HBM2E memory on a 1,024-bit wide interface. DRAM consists of stacked HBM2 memory, each stack has a 128-bit wide bus, there are a total of 8 stacks, forming a 1,024-bit interface. This will make the MI200’s memory bandwidth estimated at 3.64 TB/s.
Setonix and its more than 750 MI200 GPUs will be used to process data from the square kilometer array telescope, which will be put into use later this year.
