Asus says its team of extreme overclockers has officially broken the CPU frequency world record by overclocking the Intel Core i9-13900K to over 9GHz. The company presented results recorded on an open bench system powered by an Asus ROG Maximus Z790 Apex motherboard. on Twitter.
The CPU reached a maximum clock speed of 9.009GHz and was stable enough to run Pifast in 6.85 seconds and SuperPi 32M in 3:3777ms.
Asus’ team disabled all E-cores on the Core i9-13900K and disabled hyperthreading, limiting the CPU to only 8 P-cores and 8 threads. The team used an unusual combination of liquid nitrogen (LN2) and liquid helium for cooling. According to his SkatterBencher, one of Asus’ overclockers, the Core i9-13900K is one of the “best performing” CPUs he’s seen under liquid helium. 250 degrees Celsius, not much variation.
This record is very impressive. The 9GHz barrier has been elusive for decades, even with the best CPUs and even the most experienced extreme overclockers.The first CPUs to approach 9GHz were AMD’s FX series processors. Overclockers have exceeded 8GHz over the years. AMD’s FX lineup may have been one of the worst CPU designs ever, but it was one of the most capable platforms when it came to frequency scaling with LN2 cooling.
Many FX series processors are still inducted into the HWBot Hall of Fame today. For example, Stilt’s 8.722GHz FX-8370 result was the second highest clocked CPU ever, surpassing Asus’ record today.
The improvements Intel has made to the Raptor Lake process node are definitely why we’re looking at new world records. Raptor Lake is Intel’s highest clocking CPU architecture ever, with a boost clock that allows him to hit 5.8GHz out of the box for the Core i9-13900K. 6GHz (no manual tuning).
That’s over 9000!!!! ASUS Overclocker broke the 9 GHz barrier and smashed the previous CPU frequency record. This makes the ROG Maximus Z790 Apex the record-breaking champion of the Z790, with 14 world records and a GFP score of 29. 🏆 @intel @IntelGaming pic.twitter.com/hVs4uJTqdbDecember 21, 2022
