A full-fledged high-end APU from AMD has been in the news for years, now it may arrive: in the form of a modification of the Instinct MI300. The newly introduced version of the Instinct Mi200, which is clearly intended as an accelerator for supercomputers, could therefore open up an entirely new product class.

Talking for years…

The concept of “mega-APU” first appeared in 2015, then it was an exascale vision with 32 cores, GPU and stacked DRAM. Basically, the rumors were just that, as developments continued in this direction for years to come, although they have now been supplemented and expanded with suitably new possibilities: first and foremost chiplet technology in AMD and perhaps even in the future. Stacking. particularly noteworthy 2017 Presentation by AMD Research with title “Design and Analysis of APUs for Exascale Computing”,

… and now maybe finished?

And this is where the Instinct MI300 will evolve as the final product, according to the latest rumours. It is no longer a pure graphics accelerator based only on cDNA3, as an offshoot of RDNA3 developed in parallel for the professional sector with a faster HBM, but will also bring its own CPU cores and thus a will become of of APU.

Recently many rumors have surfaced in this direction. it was Instinct MI300 . many types of Brought into the game, so the version in the form of an APU will probably stand out and complement the portfolio with pure classic GPU solutions.

The tapeout should be completed in these months (slight delays being discussed as is currently everywhere), and the finished silicon should be working in the laboratory before the end of this year. It usually takes a good year for products to become available, provided all testing goes according to plan.

Such a specialized solution is unlikely to be available to everyone, an additional base should probably provide accommodation. “SH5” appeared here last autumn, assigned to Zen 4, but also to MI300, but it was not yet possible to classify it. However, now gradually a picture can emerge from this. As always, such rumors should be treated with caution.
