AMD Epyc 4465P, 12C/24T, 3.40-5.40GHz, tray

EPYC 4005 does what it set out to do. It keeps AM5 simple for system builders and hosters, then adds useful headroom with Zen 5, validated DDR5-5600, AVX-512, and broader SKU coverage. The family slots cleanly between Ryzen on AM5 and the larger SP5 and SP6 platforms, giving service providers an enterprise solution without the cost of the big sockets. The SKU map covers common deployment models. The EPYC 4545P brings a 16-core at 65W for dense hosting and clean Windows Server licensing. The EPYC 4565P remains the standard 170W workhorse, whereas the EPYC 4585PX adds 3D V-Cache for latency-sensitive services that lean on a larger last-level cache. Memory validation to 192GB on four UDIMMs and steady I/O with up to 28 lanes of PCIe Gen5 round out the platform. Our data shows where that matters. The 16-core 4585PX pulls clear wins in compute- and cache-sensitive work. y-cruncher completes 4.5 to 10.2 percent faster across 1B to 10B, while the BBP runs cut time by up to 38.6 percent. Blender benefits as well, with solid gains across Monster, Junkshop, and Classroom. In the Phoronix suite, 4585PX trims Linux kernel build time by 16.8 percent, serves 36.9 percent more Apache requests per second, and posts a 78.6 percent uplift in OpenSSL verify. STREAM and 7-Zip tilt modestly toward the prior 4564P in our configuration. EPYC 4005 is a measured but meaningful update from AMD. It preserves the economics and simplicity that made 4004 easy to adopt, then improves practical performance and flexibility across a wide swath of hosted and edge use cases. If you are building single-socket AM5 servers at scale, this is the right default for new deployments and a sensible upgrade when cache or efficiency is on the table. Especially when paired with the MSI S1012-02 server that has the internal liquid loop.
