After our recent feature comparing Intel's 8th-gen Core series against AMD's Ryzen processors, many of you have been asking us to get some older chips into the mix, with particular interest in seeing how Haswell-era processors hold up against Intel's latest offerings. That sounded like a good idea to us and we were also curious to see how well the Core i7-4770K has aged -- we first tested this CPU in June 2013. This article should also give 4790K owners a good idea of the gains they can expect when upgrading to a new Core i7-8700K . For a quick refresher, the 4770K and 4790K are both based on the Haswell architecture, with the former arriving in mid-2013 and the latter coming a year later with overclocked parts and a new range of chipsets. The 4790K is clocked 500MHz higher than the 4770K (4GHz versus 3.5GHz) and we can simulate that by overclocking the 4770K. Today's benchmark results should also be useful for Core i5 Haswell owne...
