Reading guide

Read the performance results

The 37,324 CPU Mark is a broad overall-performance measure, while the 2,700 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 185 W TDP helps size the cooling class, but it is not the same as peak wall-power consumption.

FAQ
