Intel Core i7-4790K vs Intel Core i5-4690K

The Intel Core i7-4790K and the Intel Core i5-4690K are both "Devils Canyon S" architecture desktop processors introduced by Intel in mid-2014.

Both are manufactured using a 22 nm process and support PCIe 3.0 as well as a maximum memory bandwidth of 26 GB/s. The Intel Core i7-4790K is aimed at enthusiasts and professional users who require high performance for demanding tasks such as content creation and gaming. It features 4 cores and 8 threads thanks to Intel Hyper-Threading technology and has an 8 MB Level 3 cache.

The integrated graphics unit is the Intel HD Graphics 4600. In performance tests, the Intel Core i7-4790K shows significantly higher multi-core performance compared to the Intel Core i5-4690K, while single-core performance is very comparable. The Intel Core i5-4690K targets more budget-conscious gamers and general users looking for reliable performance for everyday use and games.

It offers 4 cores and 4 threads but lacks Hyper-Threading. Its Level 3 cache is slightly smaller at 6 MB. It also integrates the Intel HD Graphics 4600. For gaming scenarios, the Intel Core i7-4790K offers a marginal advantage due to its slightly higher clock speeds and larger Level 3 cache, but the Intel Core i5-4690K remains very powerful.

Both "K" models have a similar Thermal Design Power (TDP) of around 88 watts and are unlocked for overclocking. The Intel Core i5-4690K offers better value for money for pure gaming or everyday applications, while the Intel Core i7-4790K is superior for multi-threaded applications.
