(Image credit: YouTube - TrashBench) The Core i7-6700K was once one of Intel’s best CPUs for gaming , but fast forward to 2026, and the decade-old chip is now hardly an optimal choice to pair with any modern GPU hardware, including some entry-level graphics cards. Despite this, YouTuber TrashBench put the 6700K to the test and challenged himself to see if he could overcome CPU bottlenecking with an RTX 3080 purely through overclocking. In his tests, the YouTuber pushed the Core i7-6700K to its absolute limit, exceeding safe voltage limits in an attempt to achieve his goal. Three overclocks were tested: a 4.7GHz overclock at 1.4v, a 5GHz overclock at 1.56v, and a 5.1GHz overclock at 1.65v. The YouTuber even attempted 5.2 GHz and 5.3 GHz overclocks with a vcore of 1.7 V, but sadly, neither attempt was successful. As for cooling, the 4.7GHz overclock was achieved with an air cooler, while the 5GHz and 5.1GHz overclocks were achieved using a custom loop submerged in an ice bath.…
