SC25: Estimating AMD's Upcoming MI430X's FP64 and the Discovery Supercomputer (chipsandcheese.com)

At Supercomputing 2025, AMD and Eviden unveiled the Alice Recoque supercomputer, set to become the second Exascale system in Europe. This groundbreaking system will leverage AMD's upcoming Instinct MI430X accelerators, achieving over 1 Exaflop/s of sustained performance while consuming less than 15 Megawatts of power. Speculation around the MI430X suggests it could deliver approximately 211 Teraflops of FP64 Vector performance, boosted by 432 GB of HBM4 and an impressive memory bandwidth of 19.6 TB/s. This positions the MI430X as a formidable competitor in the HPC landscape, notably surpassing AMD's previous accelerators in both performance and memory efficiency, and promising superior capabilities for memory bandwidth-intensive tasks. Simultaneously, the Discovery supercomputer, slated for delivery in 2028 at Oak Ridge National Laboratory, will replace Frontier and is expected to significantly enhance computational throughput, potentially achieving a performance increase of 3 to 5 times compared to Frontier. It will utilize HPE's new GX5000 platform alongside AMD's Venice CPUs and MI430X accelerators. Although exact configurations and HPL performance targets remain to be fully detailed, preliminary estimates suggest Discovery could reach between 3 and 8.5 Exaflops of HPL Rpeak, setting the stage for substantial advancements in scientific research and machine learning applications in the coming years.
