AMD also seems to be working on its first-generation Exascale APU product, the Instinct MI300, powered by Zen 4 CPU & CDNA 3 GPU cores. The details of this HPC chip have also been leaked over in the latest video by AdoredTV.

The first references to AMD's Exascale APU date all the way back to 2013 with more bits and pieces being revealed in the coming year. Back in 2015, the company revealed its plan to offer the EHP, an Exascale Heteorgenous Processor, based on the then-upcoming Zen x86 cores and Greenland GPU with HBM2 memory on a 2.5D interposer. The original plans were eventually scrapped & AMD went on to release its EPYC and Instinct lineup in their own CPU and GPU server segments. Now, AMD is bringing EHP or Exascale APUs back in the form of the next-gen Instinct MI300.
