AMD Instinct MI200 chiplet gets 110 compute units

AMD Instinct MI200 chiplet gets 110 compute units

Driver updates indicate that AMD is developing a successor to the Instinct MI100, which will be built on chiplets, according to the company. There are 110 compute units in the MI200 GPU, according to the latest additions to AMD's rocm database on GitHub.

That's what members of the Japanese forum Coelacanth's Dream learned after posting on the forum. The references GFX906 60, GFX908 120, and GFX90A 110 are all included in the software. The Instinct MI60 and MI100 are represented by the first two, and the Instinct MI200 is represented by the third.

The final set of numbers refers to the number of compute units contained within the device. Based on the assumption that this is the number of compute units in a single chiplet, the whole accelerator should have 220 compute units. That's about twice as many as the MI100, which has 120. The MI200 GPU is often referred as Aldebaran, after the brightest star in the constellation of Taurus.

AMD will turn off a portion of the GPU once more to ensure that there are enough working chips in the accelerators. It appears as though the entire chip will be outfitted with 128 compute units. If the number of cores per compute unit remains the same, the system should have a total of 14,080 cores with two of these chiplets, and 16,384 cores fully enabled.

Apart from that, Aldebaran has the advantage of supporting full-rate fp64, which allows the performance to be at least doubled and in some cases even quadrupled when compared to its predecessor. Also included are 64 GB or 128 GB of high-bandwidth memory (hbm2e), which, in addition to providing greater capacity, also allows for faster throughput speeds.

At the end, you meant Aldebaran rather than Arcturus ? Or it's to give some perspective to the MI100 performance ? o_O

There seems to be another typo:
"It appears as though the entire chip will be outfitted with 128 compute units" 128 doesnt fit.
