Legacy Hardware Record Broken
Overclocking expert Luumi has achieved a new HWBot world record using an older Intel Core i5 4670K processor, DDR3 memory, and liquid nitrogen cooling. The achievement knocked the previous four-core Intel Core i5 4670K Cinebench R11.5 record holder off the top spot after 12 years, securing a multicore score of 10.8 cb.
The HWBot-recognized system is built around Haswell-era Intel silicon, specifically the Core i5 4670K. This unlocked quad-core CPU features a stock base and boost frequency of 3.4 and 3.8 GHz, an 84W TDP, 6MB of cache, and Intel HD 4600 graphics, manufactured on a 22nm process.
Extreme Overclocking Setup
Luumi mounted the CPU on an ASRock Z97 OC Formula motherboard equipped with 4GB of XPG DDR3 RAM, powered by a Corsair AXi 1600 supply. Liquid nitrogen was used to cool the processor during the benchmark run, with validation files confirming a clock speed of 6,301.00 MHz.
While this is not an overall record for all quad-core processors, it sets a new benchmark within the specific Core i5 4670K category. The result highlights retro hardware achievements on competitive overclocking leaderboards without requiring modern high-end components.
The older Cinebench R11.5 benchmark continues to function on modern hardware and Windows 11 environments.
While some legacy benchmarking applications from the DirectX 10 era and earlier encounter compatibility issues on modern operating systems, Luumi utilized Windows 7 64-bit Pro for the Haswell CPU testing session.
