AMD's EPYC 8005 "Sorano" family brings Zen 5 to the mainstream SP6 platform, replacing the Zen 4-based EPYC 8004 Siena. Unlike the previous generation, Sorano does not gate features behind specific SKUs: every chip, from the 8-core 8025P to the 84-core 8635P, gets the same 6-channel DDR5 memory support, 96 PCIe Gen5 lanes, and full-size Zen 5 cores. That uniformity simplifies purchasing decisions, leaving core count, clockspeed, and power consumption as the main differentiators.
Clockspeeds are broadly inverted with core counts. The 84-core 8635P tops out at 3.45 GHz all-core turbo, while the 24-core 8225P reaches 4.1 GHz and the 8-core 8025P goes higher still. The 16-core 8125P is an outlier, with a lower all-core turbo than the 24-core part. All SKUs share a 4.5 GHz single-core turbo, so lightly threaded workloads see consistent headroom.
Power efficiency improves as core counts rise, because the IOD's fixed power draw is amortized across more cores. The 8635P leads at 2.7W per core, while the 8-core 8025P consumes nearly 12W per core. The jump from 64 to 84 cores costs only 15W at default TDPs, making the top-end chip the clear throughput and efficiency winner for scale-out workloads.
