AMD's CDNA 2 powered Aldebaran GPU is headed for launch in the Instinct MI200 accelerator later this year. The GPU is going to feature an MCM design and will carry a massive amount of cores and memory. With all that we know about the chip so far, Twitter fellow, Locuza, has come up with a die block diagram of the full Aldebaran GPU and it looks like a beast.

The block diagram is based on the latest details shared by Kepler_L2 for the CDNA 2 powered GPU. It was already confirmed that the Aldebaran GPU powering the Instinct MI200 will feature two dies, a secondary and a primary. The block diagram shows the two dies with each consisting of 8 shader engines for a total of 16 SE's. Each Shader Engine packs 16 CUs with full-rate FP64, packed FP32 & a 2nd Generation Matrix Engine for FP16 & BF16 operations.
