AMD: Instinct MI200 CDNA 2 Accelerators will be launched at the end of the year

AMD separated the GPU architectures of game graphic cards and professional graphic cards last year. The architecture of game graphic cards is RDNA, while the architecture of professional graphic cards is called CDNA. The first product is the Instinct MI100 series. At the Global Technology, Media, and Communications Conference held in June, AMD CEO Dr. Lisa Su briefly mentioned the cDNA 2 architecture and its products and said that it will be launched within the year. The Q2 quarterly earnings report released last month has confirmed that the CDNA 2 GPU has been shipped to customers.

In the August investor briefing, AMD updated the description of CDNA 2. Although it has not announced the specific process nodes it uses, it means that the GPU chiplets and I/O chips use different node processes. The GPU core code name of CDNA 2 is Aldebaran. It will become AMD’s first product in the MCM multi-chip package. If nothing happens, the product will be called Instinct MI200.

The MCM packaged CDNA 2 will integrate two Dies inside, and the core size can be easily doubled. There are 128 groups of CU units on each chip. If each group of CU still has 128 stream processors, it is expected to have 16,384 stream processors and it is expected to be equipped with 128GB of HBM2e video memory. The current Instinct MI100 professional card has only 7680 stream processors and 32GB of HBM2 video memory.

The competitors of AMD Instinct MI200 are Intel Xe-HP(C) and NVIDIA Hopper. What’s interesting is that these professional cards all adopt the MCM package, which means that the GPU market will enter a new era.
