Right smack dab in the middle of the lineup is the Core i9-7900X, which has a base clock of 3.3GHz, Turbo Boost 2.0 clock of 4.3GHz and Turbo Boost Max 3.0 clock of 4.5GHz. However, extreme enthusiasts are not content with mere stock speeds, which is why we are happy to report that the Core i9-7900X has already been overclocked to insane speeds, and is shattering benchmark records along the way.
Elmor, the same person that chalked up a world record by overclocking the AMD Ryzen 7 1800X to 5.8GHz, managed to overclock the Core i9-7900X to an impressive 5.7GHz. This insane overclock was of course achieved using liquid nitrogen (LN2). Coming in a 5,755MHz, the 10-core HEDT processor managed to score 3181 points in Cinebench R15 (the previous record was 3137). Moving on to Cinebench R11.5, the processor was pushed just a tad further to 5,785MHz and earned a score 34.79 (previous was 33.86).
Elmor’s platform of choice was the ASUS Rampage V1 Apex X299 gaming motherboard, which was paired with G.SKILL Trident Z DDR4 memory. An ASUS GeForce GTX 1080 Ti Strix Gaming was tossed in the rig as well, although it had no part in the broken benchmark records.
The Intel Core i9-7900X has an MSRP of $999, 10 cores (20 threads), 13.75MB of L3 cache, quad-channel DDR4-2666 memory support and a TDP of 140W.
