AMD Launches EPYC 8005 "Sorano" Server CPUs: 84 Zen 5 Cores at 225 Watts Targets Telco, Edge and Cloud Storage

Advanced Micro Devices (AMD) officially launched its EPYC 8005 series server processors on May 19, 2026, bringing the Zen 5 architecture to its single-socket edge and telco server lineup. The series, codenamed "Sorano," succeeds the EPYC 8004 "Siena" generation and extends full Zen 5 cores - rather than the compact Zen 5c variant used in the flagship EPYC 9005 series - to the edge and telco market segment.

Product Specifications

The EPYC 8005 series spans eight SKUs ranging from 8 to 84 cores within a 70 to 225 watt thermal design power (TDP) envelope, all in a single-socket configuration. The top-of-stack processor, the EPYC 8635P, carries 84 Zen 5 cores and 168 threads, a 4.5 GHz boost clock, 1.6 GHz base clock, 384 MB of L3 cache, and a 225-watt default TDP. List price for the EPYC 8635P is $5,799 at 1,000-unit quantities according to ServeTheHome. The full SKU lineup includes the 64-core EPYC 8535P, 48-core EPYC 8435P, 32-core EPYC 8325P, 24-core EPYC 8225P, 16-core EPYC 8125P, and 8-core EPYC 8025P.

All SKUs support 6 channels of DDR5-6400 ECC memory up to 3 TB total, 96 lanes of PCIe Gen 5, and the x86 instruction set including AVX-512.

Performance vs. Previous Generation

AMD states that compared to its 64-core predecessor, the EPYC 8534P, the new 84-core EPYC 8635P achieves 40% higher SPECrate 2017 integer performance and 9.5% higher performance per watt, based on published scores from SPEC.org. The EPYC 8534P scored 477 on SPECrate 2017 integer base; the EPYC 8635P scored 667, representing a 39.8% increase. Both results are published on SPEC.org and were measured on single-processor reference systems running Ubuntu 26.04 and GCC 15.2.0.

Performance vs. Intel

Within the same TDP class, AMD states the 84-core EPYC 8635P (225W, $5,799) delivers 91% higher SPECrate 2017 integer performance than the 40-core Intel Xeon 6716P-B (235W, $3,584), based on published SPEC.org scores dated May 11, 2026. The Xeon 6716P-B scored 349; the EPYC 8635P scored 667. AMD further states that on a combined performance-per-watt-per-dollar basis, a single-socket server built with the EPYC 8635P delivers 48% better integer performance per CPU watt per CPU dollar than a single-socket server built with the 72-core Intel Xeon 6776P-B.

On energy efficiency as measured by SPECpower_ssj 2008, AMD states the EPYC 8635P achieves 24,408 overall ssj_ops per watt, compared to 21,433 for the Intel Xeon 6776P-B and 13,218 for the NVIDIA Grace CPU Superchip, at maximum TDPs of 225W, 325W, and 500W respectively.

Cloud Storage

In Phoronix Test Suite testing conducted as of May 19, 2026, single-socket servers with the EPYC 8635P delivered approximately 1.23 times the CephFS RADOS throughput of systems based on the EPYC 8534P, across nine benchmark tests covering write, read, and random read throughput, IOPS, and latency. The test systems ran Ubuntu 26.04 with GCC 15.2.0 and identical storage and networking configurations.

vRAN and Telco

AMD has added Low-Density Parity Check (LDPC) decoding optimizations in the EPYC 8005 series targeting Layer 1 processing in 5G vRAN deployments, designed to reduce latency and accelerate forward-error-correction processing while preserving deterministic vRAN behavior.

In tests conducted by Samsung, a multi-cell vRAN deployment on a single server equipped with an 84-core AMD EPYC 8635P achieved support for 54 cell networks with 9.5 Gb/s downlink and 2.0 Gb/s uplink throughput. Michael Kim, Vice President and Head of vRAN Software R&D Group Networks Business at Samsung Electronics, stated: "By combining AMD's processing technology with Samsung's commercially proven vRAN software, we are accelerating the industry's transition to AI-ready, cloud-native networks."

The EPYC 8005 series supports NEBS-compliant OEM designs enabling deployment in outdoor and environmentally challenging telco and edge locations.

Retail Edge AI

WobotAI, which delivers video AI agents for in-store retail intelligence, confirmed deployment on servers running AMD EPYC 8005 Server CPUs. Will Kelso, President of WobotAI, stated: "With AMD EPYC 8005 Server CPUs, our platform runs entirely at the edge - delivering high performance in a small footprint. That means less reliance on GPUs and the cloud."
