Review on Intel Core i7-4790K CPU (8M Cache, up to 4.40 GHz) - BX80646I74790K by Micha Kumicki ᠌

Bought at the beginning of December 2022. Made a system upgrade after an old i5-750 (2.66 GHz) I took my mother Gigabyte Z97X-SLI, bought a second GTX 670 - plugged it into SLI (which is an order of magnitude cheaper than upgrading a video card). Power supply 750 W. coped with a bang. I deliberately overpaid and took it with the K index, hoping for normal overclocking (with the Icehammer IH-4500 cooler). But that was not the case. Without overheating and leaving the system in reboot, I achieved stable operation only at 4.5 GHz (with a voltage of 2.66 V, above 3 V. already wild overheating at 100 degrees). Although, as Gigabyte mocks, there is a 5 GHz profile in the overclocking utility. But without replacing the thermal interface under the processor cover, such a frequency cannot be achieved 100%. When the cores are heated to 98 degrees, the cooler remains slightly warm, although it is installed correctly and on normal thermal paste. To justify Intel, it is worth noting that the percentage is overclocked by 500 Mhz from the factory (compared to 4790) and by default it accelerates up to 4.4 GHz, which is more than enough for any task. In games, the video system becomes a bottleneck, even with a top-end video card. For comparison, the stability test of the WinRAR system with multithreading enabled with an old i5-750 (2.8 GHz) and a subject (4.4 GHz): 2947-i5 750 9561 - i7 4790K The difference is impressive
