AMD® EPYC™ 9825

The AMD EPYC 9825 is a server processor with 144 cores and 288 threads, built on the Zen 5 architecture (3 nm process). It launched in Oct 2024. Clocks run from 2.2 GHz base to 3.7 GHz boost. A 384-MB L3 cache backs the cores (3.7 MB per core). It supports DDR5 memory. The chip drops into the SP5 socket and exposes PCIe 5.0. Rated TDP is 390 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD EPYC 9825 has 144 physical cores and runs 288 logical threads. It runs 2 threads per core. It runs at a base clock of 2.20 GHz and boosts up to 3.70 GHz.

The AMD EPYC 9825 is a server processor, belongs to the AMD EPYC family, uses the Zen 5 architecture and is manufactured on a 3 nm process. It launched in Oct 2024.

The AMD EPYC 9825 has 144 MB of L2 cache and 384 MB of L3 cache. That adds up to about 528.0 MB of cache, or 3.67 MB per core. Each core has 1 MB of private L2 cache. Feex has no recorded L1 cache size for this processor.

The AMD EPYC 9825 has a 2-level cache hierarchy: L2 at 144 MB and L3 at 384 MB. L3 is the largest level and makes up about 73% of the cache listed here.

The AMD EPYC 9825 supports DDR5 memory, uses 12 memory channels, runs memory at up to 6,400 MT/s and delivers up to 614.4 GB/s of memory bandwidth. It does not support DDR4 and LPDDR memory.

The AMD EPYC 9825 does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD EPYC 9825 uses the SP5 socket and supports PCI Express 5.0.

The AMD EPYC 9825 has a rated TDP of 390 W.
