AMD CEO Lisa Su introduced the system, dubbed Project 47, as a platform suitable for both deep learning workloads and image rendering applications. Su said the machine is powered by 20 EPYC CPUs and 80 Radeon Instinct GPUs, and contains 10 TB of DDR4 memory.

Project 47 is a joint collaboration between AMD, Inventec, Samsung, and Mellanox. Inventec, a Taiwan-based original design manufacturer (ODM), built and integrated the system, based on its P-series 2U server platform. Samsung supplied the high bandwidth memory (HBM2) memory for the Radeon Instinct cards, as well as DDR4 main memory modules and NVMe SSD storage devices, while Mellanox contributed its EDR (100 Gbps) adapters, cabling, and switches to hook together the 20 servers.
In this case, each server contains a single EPYC 7601 CPU hooked to four Radeon Instinct MI25 GPUs. The advantage of the single-socket EPYC server is that it is able to support plenty of memory, GPU cards, and other PCIe devices, without have to resort to a second CPU installed solely to hook in more componentry. That saves not only the extra expense of the CPU, but power as well -- something AMD has touted as one of the major advantages of its EPYC design.
I scrounged for a month and a half to get 16K for my Timex-Sinclair! That was so I could play Frogger and Space Invaders in black and white!
