Right after the official launch of the 9th gen CPU lineup, Intel hired professional overclockers to demonstrate the potential of the new Core i9-9900K processors. Using liquid nitrogen, the 8-core CPU was pushed to 6.9 GHz (7.1 GHz unstable), but performance gains do not look that impressive. The CPU can easily be pushed to 5.3 GHz using watercoolers, though.

The review embargo for Intel’s new gen 9 mainstream Core CPUs is still in place, but that does not really stop professional overclockers to play around with the new 8-core i9-9900K flagship, especially when hired by the people at Intel themselves. After all, these overclocked results help hype things up and divert attention from the misleading commissioned reviews issue.

Among the overclockers who tried their hand at the new i9-9900K chip was Splave, a respected figure in the modding community. He managed to push the CPU to 6.9 GHz on all eight cores using liquid nitrogen and Vcore voltages set to 1.7 V.  The liquid nitrogen helped bring down the temperature to -190C, and, at some point, Splave managed to reach 7.1 GHz on all cores, but not all tested samples were stable in this regard. Moreover, peak frequencies for single-core mode reached 7.4 GHz.

Now, if liquid cooling seems a bit too much for conventional users, Splave also overclocked the i9-9900K using a more affordable watercooler and managed to reach 5.3 GHz on all cores with the usual 1.4 V voltage. Splave talk to the Tom Hardware’s staff and mentioned he was impressed with the improved heat dissipation and overclocking potential facilitated by the new Solder TIM material.

Intel showcased some benchmark results for the 6.9 GHz i9-9900K, but the performance gains do not seem too over the top. Reviews for the 9th gen mainstream flagship should be released in a few days, so we will then see how well this chip can perform at 5.3 GHz.

I stepped into the wonderous IT&C world when I was around 7. I was instantly fascinated by computerized graphics, be them from games or 3D applications like 3D Max. I like to keep myself up to date with all the new technologies that get released at an ever increasing rate these days. I'm also an avid SciFi reader, an astrophysics aficionado and, as of late, a crypto geek.
