A summary based on specifications and results.
Intel Xeon 638 is a Server processor with 16 cores and 32 threads. It runs at 3.2 GHz and boosts up to 4.8 GHz. It records a PassMark CPU Mark of 56243 and a single-thread rating of 3842. Its stated TDP is 180 W.
Specification context
The Intel Xeon 638 is a Server released in 2026. Recorded specifications include 16 cores and 32 threads, up to 4.80 GHz turbo, a 180 W reference TDP, a 56,243 CPU Mark. Use these figures to understand its position, then compare the results with your software and the complete platform.
The 56,243 CPU Mark is a broad overall-performance measure, while the 3,842 single-thread result adds context for less-parallel work. Compare the nearby alternatives on this page and do not treat one score as a verdict for every application.
It uses socket LGA4710. A matching socket is only the first check; confirm the official motherboard CPU-support list, BIOS revision and board power limits.
Recorded memory support: DDR5. The 180 W TDP helps size the cooling class, but it is not the same as peak wall-power consumption.
FAQ
The main recorded details are 16 cores and 32 threads, up to 4.80 GHz turbo, a 180 W reference TDP, a 56,243 CPU Mark. The tables on this page show socket, memory, cache and graphics data when available.
The product name or CPU Mark alone cannot answer that. Check single-thread performance, core count, the target graphics card, gaming resolution and results from the games you play.
Start with LGA4710 motherboards, then confirm the official CPU-support list and required BIOS revision for the exact board before buying.
The recorded reference TDP is 180 W. Real consumption can be lower or higher depending on power limits, motherboard, workload and cooling.
This guidance interprets recorded specifications and results; it does not claim hands-on device testing. Results can vary with motherboard, power, memory and cooling.
