Reading guide

Read the performance results

The 90,925 CPU Mark is a broad overall-performance measure, while the 3,451 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.

Platform and compatibility

It uses socket LGA4677. A matching socket is only the first check; confirm the official motherboard CPU-support list, BIOS revision and board power limits.

Memory and power

Recorded memory support: DDR5-4800. The 350 W TDP helps size the cooling class, but it is not the same as peak wall-power consumption.

FAQ

Common processor questions

What are the key Intel Xeon w9-3495X specifications?

The main recorded details are 56 cores and 112 threads, up to 4.80 GHz turbo, a 350 W reference TDP, a 90,925 CPU Mark. The tables on this page show socket, memory, cache and graphics data when available.
