The Dell PowerEdge R9825 is the dual-socket flagship of the 18th Generation PowerEdge line: a 3U rack server with two 6th Gen AMD EPYC 9006 Series (SP7) processors, up to 256 cores each and 512 cores per system, at up to 600 W per socket on air cooling. With 32 DDR5 DIMMs (16 channels per CPU, up to 8000 MT/s RDIMM or 12800 MT/s MRDIMM), all-NVMe E3.S Gen6 front storage, up to eight PCIe Gen6 x16 slots and iDRAC10, it is built for agentic AI, HPC and enterprise workloads, and replaces racks of older dual-socket servers with one 3U system.
