"Of the compute blades, the most notable is the Nvidia-based GX440n Accelerated Blade, which will feature 4 Vera CPUs and 8 Rubin GPUs for "mixed-precision computing," which we take to mean AI as well as more traditional HPC workloads. Each Vera CPU comprises 88 custom-designed Arm cores, while Rubin is the successor to Nvidia's current Blackwell GPUs, scheduled for release in 2026. Each Cray rack can be configured with a maximum of 24 of these blades for up to 192 Rubin GPUs per rack, HPE said."
"The remaining two blades will be based on AMD's sixth-gen Epyc processors, codenamed Venice, which are also expected to launch in 2026 and understood to feature up to an impressive 256 CPU cores each. The GX350a Accelerated Blade is similarly aimed at mixed-precision computing, with one Venice CPU and 4 of AMD's Instinct MI430X series GPUs. Up to 28 of those blades can be configured per rack, for a total of 112 MI430X accelerators. For customers wanting to build a CPU-only cluster, the GX250 Compute Blade fits eight of those AMD Venice chips, and up to 40 of those blades will fit in each rack, enabling up to 81,920 CPU cores."
HPE's Cray GX5000 is the next iteration of the company's HPC architecture offering liquid-cooled compute racks and new management tools. Three compute blades will be offered initially: the Nvidia-based GX440n with four Vera CPUs and eight Rubin GPUs for mixed-precision workloads; the AMD-based GX350a with one Venice Epyc and four Instinct MI430X accelerators; and the GX250 CPU-only blade with eight Venice Epyc chips. Vera CPUs have 88 custom Arm cores each; Venice Epyc is expected to offer up to 256 cores. Racks support mixed-node configurations. Storage K3000 ships early 2026; compute nodes target early 2027 availability.
