332 el captin2/26/2024 ![]() Supinski said the chip comes with an Infinity Cache but didn't specify the capacity available. Supinksi often referred to the MI300 as the "MI300A," but we aren't sure if that is a custom model for El Capitan or a more formal product number. Supinksi also showed a picture of AMD's Austin lab, where they have working MI300 silicon, thus showing that the chips are real and already under testing - a key point to be made considering some of the recent missteps with Intel-powered systems. ![]() This blade, made by system vendor HPE, features four liquid-cooled Instinct MI300 cards in a slim 1U chassis. The National Nuclear Security Administration (NNSA) will use El Capitan to further military uses of nuclear tech.Īs you can see in the first image in the above album, Supinski showed a single blade for the El Capitan system. de Supinski, the CTO for the Lawrence Livermore National Laboratory (LLNL), spoke about integrating the Instinct MI300 APUs into the El Capitan supercomputer. AMD Instinct MI300 in El CapitanĪt ISC 2023, Bronis R. We also threw in a few pictures of the Instinct MI300 silicon we saw firsthand, but below we see how the MI300 looks inside an actual blade that will be installed in El Capitan. The MI300 topology map also indicates that each chip has three connections, just as we saw with MI250. Papermaster's slides also refer to the active interposers that form the base dies as the 'fourth-gen infinity fabric base die."Īs you can see in the remainder of these slides, the MI300 has placed AMD on a clear path to exceeding its 30X25 efficiency goals while also outstripping the industry power trend. That's a potential pain point with the MI250 topology. This type of connection allows all of the processors to speak to each other directly without another CPU or GPU serving as an intermediary to relay data to the other elements, thus reducing latency and variability. However, the same overall topology remains, sans the standalone CPU, enabling a fully-connected all-to-all topology with four elements. ![]() In contrast, the Instinct MI300 contains a built-in 24-core fourth-gen EPYC Genoa processor inside the package, thus removing a standalone CPU from the equation. Papermaster's ITF World keynote focused on AMD's "30x25" goal of increasing power efficiency by 30x by 2025, and how computing is now being gated by power efficiency as Moore’s Law slows. Key to that initiative is the Instinct MI300, and much of its gains come from the simplified system topology you see above.Īs you can see in the first slide, an Instinct MI250-powered node has separate CPUs and GPUs, with a single EPYC CPU in the middle to coordinate the workloads. Overall the chip weighs in with 146 billion transistors, making it the largest chip AMD has pressed into production. The nine compute dies, a mix of 5nm CPUs and GPUs, are 3D-stacked atop four 6nm base dies that are active interposers that handle memory and I/O traffic, among other functions. We'll also cover some of the other new developments around the El Capitan deployment.Īs a reminder, the Instinct MI300 is a data center APU that blends a total of 13 chiplets, many of them 3D-stacked, to create a single chip package with twenty-four Zen 4 CPU cores fused with a CDNA 3 graphics engine and eight stacks of HBM3 memory totaling 128GB. AMD's powerful Instinct MI300 will power the machine, and new details include a topology map of a MI300 installation, pictures of AMD's Austin MI300 lab, and a picture of the new blades that will be employed in the El Capitan supercomputer. The El Capitan supercomputer is poised to be the fastest in the world when it powers on in late 2023, taking the leadership position from the AMD-powered Frontier. We also found other details in a keynote from AMD's CTO Mark Papermaster at ITF World 2023, a conference hosted by research giant imec (you can read our interview with Papermaster here). Now we've gathered some new details from an International Super Computing (ISC) 2023 presentation that outlines the coming two-exaflop El Capitan supercomputer that will be powered by the Instinct MI300. AMD's Instinct MI300 is shaping up to be an incredible chip with CPU and GPU cores and a hefty slab of high-speed memory brought together on the same processor, but details have remained slight.
