Overclockers surpassed the elusive 9GHz clock speed. Here’s how they did it

Asus has just announced that its team managed to break yet another world record, this time by overclocking the Intel Core i9-13900K to an extreme level.

The CPU was able to hit a whopping 9.009GHz, surpassing the previous 8.8GHz record. Intel shared a video that describes the whole process, which involved some quite innovative solutions.

Intel’s recent Raptor Lake CPU, the Core i9-13900K, is undoubtedly one of the best processors out right now. Most of us will use it for gaming, work, and anything in-between — but when such a beast falls into the hands of extreme overclocking enthusiasts, the results can be incredible. The CPU was paired with an Asus ROG Maximus Z790 motherboard, and to get to that 9GHz milestone, the team had to improvise and get creative.

First, the overclockers turned off all of the efficiency cores (E-cores) and disabled hyperthreading. This means that the CPU was running only eight performance (P) cores and eight threads. Overclocking at this level is often done with the help of liquid nitrogen, but that wasn’t enough to break past the 9GHz limit.  The team resorted to using a mix of liquid nitrogen (LN2) and liquid helium.

Liquid helium can be tricky, as it runs at around -269 degrees Celsius. That was necessary to keep the Core i9-13900K stable, and in the video shared by Intel, SkatterBencher remarks that the chip handled the pressure well. The team ran into other problems, though, such as the USB ports freezing and the motherboard running too cold. In the end, they had to cool the CPU while warming up the motherboard to hit the 9.009GHz record. The processor was able to run PiFast at that frequency for 6.85 seconds and SuperPi 32M for a total of 3 minutes and 3 seconds.

ASUS pushes Intel Core i9-13900K to 9.008 GHz, Setting a new World Record!

The 9GHz CPU frequency barrier has been elusive up until now. Many professional overclockers have tried to reach 9GHz, but so far, only Asus’ team seems to have achieved that milestone. Hitting extremely high clock speeds is not a first for the Core i9-13900K, though.

The CPU has also recently hit 8.8GHz, setting a new world record, but as we now know, the victory was short-lived. Fun fact: the recent Core i9-13900K win belongs to Elmor, who was also involved in today’s 9GHz success. Prior to that, the title of the highest CPU frequency belonged to the less-than-impressive AMD FX-8370 with a clock speed of 8.722GHz. While that lineup of processors had nothing on AMD’s Ryzen tech that came later, it seems to respond particularly well to liquid nitrogen and overclocking in general.

It’s impressive how long it took for AMD to lose the No. 1 spot for the highest clock speed. The 8.722GHz record was set all the way back in 2014, and up until October of this year, AMD reigned supreme. Finally, Raptor Lake swooped in and broke the record, and now with Asus’ efforts, both first and second place belong to the Intel Core i9-13900K.

Intel CPU gaming crashes are causing an uproar
Intel Core i9-13900K held between fingertips.

Some of Intel's best CPUs may be having stability issues in Unreal Engine 4 and 5 games. According to reports from frustrated users, CPUs like the Core i9-13900K or the Core i9-14900K run into shader compilation issues in certain games, resulting in crashes. The community found a fix that seems to work for most people, but it's more of a workaround than a real solution.

Reports about these problems have been flooding various Steam forums and Reddit communities for months afterSebastian Castellanos on X (formerly Twitter) brought them to light. It appears that people are experiencing these problems primarily in UE4/5 games. During the initial shader compilation stage, the game crashes to desktop. Affected titles include Hogwarts Legacy, Fortnite, Remnant 2, Nightingale, and more.

The iPhone 15’s chip challenges Intel’s fastest desktop CPU — but there’s a catch
Intel Core i9-13900K held between fingertips.

Who would have thought that some of the best CPUs would face competition not from a desktop or laptop CPU, but from a mobile system-on-a-chip (SoC)? Well, the latest Geekbench 6 scores prove that it's possible. Apple's new A17 Pro chip, announced during the September 2023 Apple event and found in the iPhone 15 Pro and Pro Max, challenges AMD and Intel -- but there's a catch.

Yes, it's real. The Geekbench 6 test gives the A17 Pro chip a score of 2,914 in single-core operations, and that's mighty impressive for something that will end up in a smartphone. However, the generational leap is not that impressive -- the last-gen A16 Bionic chip is only around 10% behind in terms of single-threaded performance. The A17 Pro was built based on TSMC's 3nm technology, while the A16 Bionic is a 5nm chip, also made by TSMC.

AMD Ryzen 9 7950X3D vs. Intel Core i9-13900K: only one choice for PC gamers
AMD's Ryzen 9 7950X3D inside of its packaging.

The AMD Ryzen 9 7950X3D and Intel Core i9-13900K are undoubtedly two of the best processors you can buy, but they aren't equal. We threw both of the CPUs on the test bench to answer the age-old question: is AMD or Intel better?

Based on our testing, the Ryzen 9 7950X3D wins this bout, mostly on the back of the excellent gaming performance AMD's 3D V-Cache technology brings. Intel's Core i9-13900K still holds up, particularly in productivity apps, but Team Red takes the win this time around.
