AMD kicked off Computex with a few pretty significant announcements: its new Instinct MI325X accelerators (pictured), which will be available in the fourth quarter of 2024; the upcoming Instinct MI350-series powered by the CDNA4 architecture that will launch next year; and the all-new CDNA 'Next'-based Instinct MI400-series products set to come out in 2026.

Perhaps the most significant announcement is that AMD's updated product roadmap commits to an annual release schedule, ensuring continuous increases in AI and HPC performance with enhanced instruction sets and higher memory capacity and bandwidth.

  • It's good to see AMD offering a refresh or a completely new AI accelerator each respective year.

    The MI325X AI accelerator appears more like a interim solution, since it is a beefed-up refresh of the current MI300X, composed of eight compute, four I/O, and eight memory chiplets stitched together.

    So AMD is now confident that its MI325X system could support 1 trillion parameter model ? But they are still focusing on FP16, which requires twice as much memory per parameter as FP8.

    MI300X does have hardware support for FP8, but AMD has generally focused on half-precision performance in its benchmarks. At least for inferencing/vLLM, the MI300X was stuck with FP16. And vLLM lacks proper support for FP8 data types.

    This isn't any apples-to-apples comparison though. But while it's great to have 288GB of capacity, I'm just worried the extra memory doesn't get overshadowed in a model that would run at FP8 vs Nvidia's H200.

    Because that would still require extra memory on the MI325X, twice to be precise. But it appears AMD might have overcome this limitation with this new accelerator .

    I hope so !

    Instead of dubbing the future architecture as "CDNA Next" AMD should refer it as CDNA 4++ , or just CDNA 5 for sake of clarity.
