AMD Radeon Instinct MI50 32GB

32 GB HBM2 · 4096-bit · 3,840 cores

The Radeon Instinct MI50 is a 7 nm Vega 20 data center accelerator for machine learning and mixed-precision HPC. Sixty compute units and 3,840 stream processors deliver 26.5 TFLOPS of half precision, 13.3 TFLOPS of single precision and 6.6 TFLOPS of double precision, the last at a full 1:2 rate that made the card unusually strong for scientific work in its class. Rapid Packed Math plus INT8 and INT4 dot-product instructions accelerate inference. This 32 GB configuration doubles the frame buffer of the 16 GB model over the same 4,096-bit HBM2 interface and 1 TB/s of bandwidth. The MI50 was among the first accelerators to ship with PCI Express 4.0, and the passively cooled full-height double-slot card draws 300 W.
