Intel Core i7-4790K vs Intel Core i5-8500

The Intel Core i7-4790K (Devils Canyon S), introduced mid-2014 for enthusiasts, is manufactured using the 22 nm process.

It offers 4 cores, 8 threads, 8 MB Level 3 Cache, and a maximum memory bandwidth of 26 GB/s. The integrated graphics unit is the Intel HD Graphics 4600. The Intel Core i5-8500 (Coffee Lake S), released in early 2018 for the mainstream market, is produced using the finer 14 nm process.

It features 6 cores, 6 threads, 9 MB Level 3 Cache, and a maximum memory bandwidth of 43 GB/s. The integrated graphics solution is the Intel UHD Graphics 630. Both CPUs utilize PCIe 3.0. In single-core performance, both processors are comparable in benchmarks. However, in multi-core applications, the Intel Core i5-8500 shows noticeably higher performance, due to its superior core count.

For gaming, the Intel Core i5-8500 generally offers better performance in modern titles, thanks to additional cores and higher memory bandwidth. The Intel Core i7-4790K can compete in specific scenarios through overclocking. The power consumption of the Intel Core i5-8500 at 65W TDP is more efficient than the 88W of the Intel Core i7-4790K.

The price-performance ratio of both older processors is now determined by the used market. The Intel Core i7-4790K was a top-tier model of its time, while the Intel Core i5-8500 was an efficient mid-range option. For most modern applications and games, the Intel Core i5-8500 is the more sensible choice due to more cores and higher efficiency.

The Intel Core i7-4790K is suitable for users who explicitly want to utilize overclocking or for older workloads with a strong single-thread focus.
