AMD's upcoming MI250X GPU was detailed at Hot Chips 34, where we get the GPU block diagram that gives us all the good stuff in terms of specifications and details.

By using 1,024 AMD Instinct MI250X accelerators paired with AMD EPYC CPUs in Frontier, the simulation time was slashed to 1.5 hours. This is more than 25 times faster, ...

For traditional HPC workloads, AMD’s MI250X is still a powerhouse when it comes to double precision floating point grunt. Toss some AI models its way, and AMD’s decision to prioritize HPC becomes ...

Frontier — once the fastest box on the planet before being nudged aside by El Capitan — runs on 9,408 EPYC processors and 37,632 MI250X GPUs. El Capitan, meanwhile, flexes 44,544 of AMD’s ...

Inside, there were 3000 x AMD Instinct MI250X AI GPU accelerators, and while they're older models -- AMD has announced its new Instinct MI300X AI GPUs -- the records speak for themselves.

The MI250X will pack two CDNA 2 GPUs with 220 CUs (110 per GPU), 880 2nd gen Matrix Cores (440 per GPU), and a total of 128GB of HBM2E at 3.2 TB/s.

Notably, the world's fastest supercomputer, Frontier, runs on 3rd-Gen AMD EPYC™ CPUs and Instinct MI250X accelerators, pointing to its leading position in data center end-market.

The MI250X includes two graphics cards based on a six-nanometer process, as well as 128 gigabytes of onboard RAM for storing AI models’ data.

The MI250X is AMD's most powerful GPU/accelerator, and it only sells it to select partners. It has 220 CUs containing 14,080 cores clocked at 1700 MHz in a 500 W package.

The AMD Instinct™ MI250 (500W) / MI250X (560W) OAM accelerators (128 GB HBM2e) designed with AMD CDNA™ 2 6nm FinFet process technology resulted in 128 GB HBM3 memory capacity and 3.277 TFLOPS ...

The researchers needed 14TB RAM minimum to achieve these results, according to their paper, but each MI250X GPU only had 64GB VRAM, meaning the researchers had to group up several GPUs together.
