The AMD Instinct MI250X accelerator received the world’s first dual-chip graphics processor. Radeon RX 7000 graphics cards are expected to launch in the second half of the year, where both top GPUs will be dual-chip. However, AMD is already working on a much more complex and almost unique GPU, and it would be wrong to call it a graphics processor.

It seems that the first data from AMD’s internal documents and even a blurry photo surfaced on the Internet.

So, we are talking about the Instinct MI300 accelerator. More precisely, most likely, the Instinct MI300 is a line, and a particular model can be called Instinct MI350X or something else, but it does not matter. The important thing is that it is technically not even a GPU, but an APU, that is, a hybrid processor. Because the GPU in the CDNA3 architecture will add processor cores with the Zen 4 architecture. Also, this chip will have its own HBM memory. The documentation says it’s the Instinct APU, but in the end only we will know what AMD will call this solution. In any case, the emphasis will obviously be on the graphics part in the first place, as these are still Instinct accelerators. It can also be assumed that the processor cores will not be all models of the Instinct MI300 series. But in any case, it will be the largest, most complex and productive hybrid processor.

Judging by the image and early data, the APU can take up to eight computing chips and eight memory chips. It is not yet known whether each chip will have processor cores or whether they will receive, for example, a separate chip or more. In any case, this is a highly unusual and indeed unique solution whose productivity can only be predicted. However, AMD once talked about an exaflop-level product.

It is worth mentioning an interesting detail. The truth is, the first rumors about a big APU AMD appeared in 2019. Then, last September, we announced that the Instinct MI300 can receive both processor and graphics cores, and recently, information came about an eight-chip GPU with a total interster area of ​​2750 mm2.

Also in 2015, AMD itself mentioned the concept of Exascale Heterogeneous Processor. At that time, the company was talking about the possibility of combining 32 Zen cores, a GPU of unknown configuration, and HBM memory. Later in 2020, it was learned that AMD continued to work on the project, at least on the basis of the company’s patents.

Ultimately, the concept demonstrated seven years ago will be implemented in the next generation of Instinct accelerators. They’ll likely launch at the end of this year or early next year, as the documentation states that the first chips will leave the lab in the third quarter. Source
