Description
The AMD EPYC™ 9845 is a high-density server processor from the AMD EPYC 9005 Series, engineered for demanding AI-enabled, business-critical, cloud, and data center workloads. With 160 CPU cores and 320 threads, it provides exceptional compute density for organizations running highly parallelized and virtualized environments.
Operating at a 2.1 GHz base clock, with all-core boost speeds up to 3.25 GHz and a maximum boost clock of up to 3.7 GHz, the EPYC 9845 balances performance and efficiency across intensive workloads. It features 320 MB of L3 cache, a 390W default TDP, and configurable TDP from 320W to 400W.
Built for the SP5 platform and supporting both 1P and 2P server configurations, the EPYC 9845 offers 128 lanes of PCIe® 5.0 connectivity and a 12-channel DDR5 memory architecture supporting speeds up to 6400 MT/s and up to 614 GB/s of memory bandwidth per socket.
AMD Infinity Guard and AMD Infinity Architecture further support modern enterprise infrastructure requirements. The processor is suited for workloads including analytics, application development and testing, HPC, virtualization, networking/NFV, media streaming, security, VDI, web serving, and high-density virtual machine environments.
