AMD is gearing up to launch its first MCM GPU, the Instinct MI200 based on the Aldebaran HPC chip. The Instinct MI200 would be featuring the CDNA 2 graphics architecture and offer twice the horsepower thanks to the industry-leading multi-chip-module packaging design.
AMD Instinct MI200 'Aldebaran' HPC GPU All Set To Introduce MCM CDNA 2 Architecture
The latest information on the Instinct MI200 comes within the Linux Patch which confirms that the graphics card is indeed based on an MCM design. The patch references the two dies onboard the GPU as primary and secondary. It is stated that the primary die will fetch the valid power data while the secondary die will communicate with the first die to distribute the power balance. This will be the first time we will be getting an MCM GPU & even though those are not planned for consumers yet, AMD's next-gen RDNA 3 is expected to introduce a similar (chiplet) design on Navi 31 and Navi 32 GPUs.
Other than that, the AMD MI200 is listed as an MCM 'Special FIO Accelerator' for HPE Cray EX. That could explain where the MI200 name comes from. An MCM (Multi-Chip-Module) design could mean that we could still be looking at a Vega Compute GPU but two of them fused over the same PCB & connected by a next-generation Infinity Fabric interconnect. Following is a representation of what the AMD Aldebaran GPU could look like:
According to Coelacanth's Dream, it is reported that the MI200 accelerator will utilize a new variant of the GFX900 GPU architecture (Vega) known as GFX90A which adds support for full-rate FP64 compute capabilities. Once again, the AMD MI200 accelerator sounds like it will go ahead with NVIDIA's future Lovelace MCM GPUs for the HPC market and is expected to be introduced later this year.
