The Intel Core i5-4670K benchmark record that has held firm for nearly 12 years is finally fallen. And it took liquid nitrogen and a 13-year-old Haswell chip that pushed 66% higher than the official boost clock. It's a big lesson on the potential of the old silicon when it's taken out of the factory.

Finnish overclocker Luumi achieves 10.80 points on legacy Haswell chip
It's a real reminder on the potential of hardware, especially for the people who still hold dear legacy hardware. It is a demonstration that even old CPUs can still make significant improvements in performance with the right cooling and tuning techniques.
Specifications
- CPU Model: Intel Core i5-4670K
- Overclocked Frequency: 6,301MHz
- Cinebench R11.5 Score: 10.80 points
- Motherboard: ASRock Z97 OC Formula
- Memory: 4GB XPG DDR3 at 2,708 MT/s
Finnish overclocker Luumi was able to achieve 10.80 points on the Intel Core i5-4670K with a specialized test bench in Cinebench R11.5. The clock on the CPU was bumped to 6,301MHz thanks to some liquid nitrogen to keep things stable at those crazy frequencies. That overtakes the old 10.76-point record by Strat from October 2014 and is a big step for retro computing benchmarks. The extra clockspeeds achieved demonstrate the fine-tuning of competitive overclocking.
To do it, he used an ASRock Z97 OC Formula motherboard and some 4GB XPG DDR3 RAM at 2,708 MT/s. That's all powered by a Corsair AXi 1600W PSU to supply the juice for the high-frequency operation. All this is running Windows 7 Professional 64-bit which was the norm back when the chip first came out. The hardware choices, including the ASRock Z97 OC Formula motherboard and XPG DDR3 memory, were carefully chosen for high-frequency performance.
Luumi was also able to get 1,009 points in Cinebench R15 running at the same clockspeed. It's a consistent showing across different versions of the benchmark. "Just finding another 50MHz of stable frequency on a 13-year-old chip is as epic as it sounds," it was reported. That little bit of frequency overage pushed it just past the decade-old record and landed the top spot on HWBot. The benchmark record is a reminder of how fine-tuning can improve the performance of legacy hardware.
