AMD Instinct MI300 computing card may have Exascale APU mode
AMD will use AM5 (LGA 1718) and SP5 (LGA 6096) sockets in the next-generation desktop platform and server platform, respectively. Although there is still a long time before the release of the new Zen 4 architecture processor, there are basically no doubts, and even some CPU cooler manufacturers have already completed supporting products. However, Twitter user @ExecuFix recently discovered that AMD also has a new server socket called “SH5” with a CPUID of 0xA80F00 and a code name of “MI300”.
Such a name makes it easy to think of Instinct MI series products, which is AMD’s computing card product line.
It is understood that AMD’s computing card based on the CDNA 2 architecture GPU (code-named Aldebaran) is the Instinct MI200 and will not be launched until the end of this year, and the Instinct MI300 computing card should be a product of the CDNA 3 architecture, at least one year later on this basis. Previous news indicated that its GPU will still use MCM packaging technology, and the integrated computing module will be increased from two to four.
ExecutableFix pointed out that products that use SH5 sockets are likely to also include Zen 4 architecture CPUs. If you bring the time back to about two years ago, Twitter user @KOMACHI_ENSAKA once discovered the BIG APU mode of “MI200”. VideoCardz reported that AMD previously published a paper entitled “Design and Analysis of an APU for Exascale Computing”, which discussed a high-performance chip design, which would include CPU chips, GPU chips, and HBM memory stacks.
This may mean that the so-called “MI300” is not only no longer limited to the form of a PCIe expansion card but may also package the CPU module with the GPU module and memory. For example, when building a supercomputer, each node no longer installs CPU, GPU, or even memory separately, and directly replaces it with the “MI300” of the SH5 socket.
