Intel Core i5-2500k vs Intel Core i5-3350P

The Intel Core i5-2500k was introduced in 2011 as part of the Sandy Bridge S architecture for mainstream users and enthusiasts.

Manufactured using a 32 nm process, it offers four cores, four threads, 6 MB of Level 3 Cache, and Intel HD Graphics 3000. It utilizes PCIe 2.0 with 21 GB/s memory bandwidth. Its single-core and multi-core performance is comparable to its successor, with overclockability offering an advantage for higher gaming performance.

Energy efficiency is lower than with the newer generation. As an older model, it is available very affordably on the used market. The Intel Core i5-3350P was released in 2012, based on the Ivy Bridge S architecture, and targeted the mainstream market.

It is manufactured using a finer 22 nm process and also features four cores, four threads, and 6 MB of Level 3 Cache, but without an integrated graphics unit. With PCIe 3.0, it offers 26 GB/s memory bandwidth and slight advantages in connecting modern graphics cards. Its single-core and multi-core performance is very similar to its predecessor, and it is characterized by potentially better energy efficiency.

This older model is also available used at a low price. Summary and Recommendation: The Intel Core i5-2500k is ideal for overclocking or when integrated graphics are needed. The Intel Core i5-3350P is better suited for systems with a dedicated graphics card that benefit from PCIe 3.0 and higher energy efficiency.
