AMD has introduced the EPYC 8005 'Sorano' server processor lineup. The new chips succeed the previous EPYC 8004 'Siena' series and target edge infrastructure, telecommunications, virtual radio access networks, and dense cloud storage workloads.
New server processors feature full Zen 5 cores and six-channel DDR5 support
The flagship model in the lineup carries the designation EPYC 8635P. It features up to 84 cores with 168 threads and a maximum boost clock of 4.5 GHz. The entire series uses full Zen 5 cores rather than the smaller Zen 5c design. This architectural choice increases per-core L3 cache capacity across all models.
The processors support six-channel DDR5-6400 ECC memory with a maximum capacity of 3 TB per socket. Each chip provides 96 PCIe Gen 5 lanes for peripheral connectivity. AMD includes full AVX-512 instruction set support and adds hardware-level LDPC decoding optimizations specifically designed for 5G Layer 1 processing tasks.
AMD claims the flagship EPYC 8635P delivers 40% higher integer performance and improves performance per watt by 9.5% compared to the previous generation 64-core EPYC 8004 flagship. The company also states the chip offers a 91% advantage in integer performance while using 10W less power than Intel's 40-core Xeon 6716P-B. AMD reports a 48% better integer performance per watt per dollar ratio against the 72-core Xeon 6776P-B.
The vendor has not confirmed specific launch dates or pricing for the new EPYC 8005 series. External sources claim AMD captured a record 46.2% of server CPU revenue in Q1 2026, but this figure remains unverified within official statements.
