Reading guide

Read the performance results

The 5,107 CPU Mark is a broad overall-performance measure, while the 1,603 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 LGA1155. 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: DDR3-1333. The 45 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 E3-1265L V2 @ 2.50GHz specifications?

The main recorded details are 4 cores and 8 threads, up to 3.50 GHz turbo, a 45 W reference TDP, a 5,107 CPU Mark. The tables on this page show socket, memory, cache and graphics data when available.
