AMD Instinct MI300 will be the world's largest APU with integrated Zen 4 processor

AMD Instinct MI300 will be the world's largest APU with integrated Zen 4 processor

AMD first introduced the Instinct MI100 computing GPU based on CDNA architecture in 2020 as a competitor to Nvidia A100 to accelerate high performance computing (HPC) workloads.
Later, the CDNA 2-based Instinct MI200 and MI250X also appeared.
Now some information has emerged about the upcoming Instinct MI300 based on the CDNA 3 architecture.Advertisement The information comes from AdoredTV, which has obtained an internal slide detailing the Instinct MI300.
According to the leaked slide, the Instinct MI300 will actually be an APU with a Zen 4 architecture processor working together with a GPU and shared HBM memory.
 Insider @Komachi_Ensaka first tweeted about a big APU for the MI200 in December 2019, followed by a September 2021 tweet from @ExecuFix pointing to a new socket called SF5 supporting the MI300.
However, AMD has been considering the concept of a megaexascale APU with 32 CPU cores, a GPU and DRAM memory since 2015 and even published an article titled \"Design and Analysis of an APU for Exascale Computing\" in 2017. The recently leaked slide correlates well with the above information.
Zen 4 and CDNA 3-based APUs are expected to be completed by the end of May, with the first working sample in labs expected by the third quarter.
This would make it the largest exascale x86 APU for high-performance computing and data centers. While this information is likely true, it is unclear whether AMD will build all CDNA 3 gas pedals as APUs or produce GPUs and APUs separately.
