AMD Launches EPYC 8005 Series Server CPUs with Up to 84 Zen 5 Cores

AMD has formally launched the EPYC 8005 series, codenamed “Sorano” after its announcement at MWC 2026 back in February, and now the full details are in. The new lineup succeeds the EPYC 8004 “Siena” family and sits between the high-end EPYC 9005 and the entry-level EPYC 4005, targeting single-socket low-power platforms with eight to 84 Zen 5 cores across a 95 W to 225 W TDP range. The flagship is the EPYC 8635P featuring 84 cores, 168 threads, 384 MB of L3 cache, and a 225 W TDP with a 1.6 GHz base clock. Compared to its 64-core EPYC 8004 predecessor, AMD claims 40% higher integer performance and 9.5% better performance per watt. Against Intel’s 40-core Xeon 6716P-B at 235 W, it offers 2.1 times the core count (84 vs 40), a 10 W lower TDP (225 W vs 235 W), and 91% higher integer performance. AMD also claims 48% better integer performance per CPU watt per dollar versus Intel 72-core Xeon 6776P-B in a single-socket configuration.

The full lineup spans seven SKUs, from the 8-core EPYC 8025P at 95 W up to the 84-core 8635P at 225 W. All models are single-socket only and support six channels of DDR5-6400 ECC memory with up to 3 TB total capacity, 96 lanes of PCIe Gen 5, and full AVX-512 support. AMD is positioning the 8005 series around dense edge deployments and software-defined storage workloads. In those scenarios, core density, I/O bandwidth and power efficiency matter more than raw single-threaded performance.

According to ServeTheHome, 1K unit list pricing starts at $529 for the eight-core EPYC 8025P and $729 for the 16-core EPYC 8125P. The 64-core EPYC 8535P is listed at $5,499, while the 84-core flagship EPYC 8635P comes in at $5,799.
