![]() The predecessor “Aldebaran” GPUs already have some impressive HPC design wins for AMD, notably in the “Frontier” exascale system at Oak Ridge National Laboratory, with four of these dual-chip GPUs attached to a custom “Trento” Epyc CPU to create a more loosely coupled hybrid compute engine. But quite a number of people keep asking us if the MI300 series can be competitive with the Nvidia “Hopper” H100 GPU accelerators and, perhaps more importantly, competitive with the combination of the 72-core “Grace” Arm CPU lashed tightly to the Hopper H100 GPU to create a combined Grace-Hopper hybrid CPU-GPU complex that will go toe-to-toe with the MI300A that is going to be deployed in El Capitan and, we think, other hybrid CPU-GPU machine running HPC and AI workloads side by side.Īnd considering the intense demand for GPU compute, driven by an explosion in AI training for generative AI applications based on large language models, and AMD’s desire to have more of a play in AI training with its GPUs, we think the demand will outstrip the Nvidia supply, which means despite the massive advantage that the Nvidia AI software stack has over AMD that the latter’s GPUs are going to get some AI supply wins. Yes, this is perhaps folly, considering that AMD will likely talk a bit more about the MI300 series of GPUs at ISC 2023 and beyond, and we will eventually know precisely how this compute engine is architected. So, just for fun, we pulled out the trust Excel spreadsheet and tried to estimate what the feeds and speeds of the MI300 and the MI300A GPUs, the latter of which will be at the heart of the El Capitan system might be. ![]() UPDATED Like many HPC and AI system builders, we are impatient to see what the “Antares” Instinct MI300A hybrid CPU-GPU system on chip from AMD might look like in terms of performance and price.Īnd with the ISC 2023 supercomputing conference coming up in a few weeks, and Bronis de Supinski, chief technology officer at Lawrence Livermore National Laboratory, is giving a talk at the event about the future “El Capitan” exascale system that will be the flagship machine for the MI300A variant of the Antares GPUs, it is on our minds.
