81920 Cores Per Rack with #AMD #EPYC Venice at #HPEDiscover 2026
While we are talking about 8000 cores being decently dense in an air-cooled rack today, these #HPE #Cray nodes are aiming to be roughly 10x as dense. Perhaps more exciting is that this looks like a working system. Specifically an #HPECray #GX250a Compute Blade with AMD EPYC Venice.There are small Samsung E1.S EDSSF SSDs on top of the CPU coldplates, and the network is #Slingshot400.
