Intel Core i5-8600 vs Intel Core i5-8400

The Intel Core i5-8400 and Intel Core i5-8600 are Intel's 8th generation desktop processors, both released in the fourth quarter of 2017.

They are based on the 14 nm Coffee Lake S architecture with 6 cores, 6 threads, 9 MB Level 3 Cache, PCIe 3.0, and a maximum memory bandwidth of 43 GB/s. An Intel UHD Graphics 630 is also integrated. The Intel Core i5-8600 offers slightly better single-core performance than the Intel Core i5-8400 due to higher clock frequencies.

In multi-core applications, the Intel Core i5-8600 is over 10 percent more powerful. Both are well-suited for gaming, with the Intel Core i5-8600 having a slight advantage thanks to higher clock speeds. The integrated graphics are insufficient for demanding gaming. Both CPUs have a Thermal Design Power (TDP) of 65 watts; power consumption and cooling requirements are moderate.

The Intel Core i5-8600 might consume slightly more power under full load. As older models, both are primarily available on the used market and offer good value for money there. The Intel Core i5-8400 is a cost-effective choice for everyday tasks. The Intel Core i5-8600 delivers noticeably better performance in more demanding applications and gaming due to higher clock speeds, making it the better option for performance-oriented users with a small price difference.
