Overclocker Luumi has claimed the top spot in HWBot's Cinebench R11.5 rankings for the Intel Core i5-4670K, ending a record that had stood for approximately 12 years. Running the 2013 Haswell quad-core at 6,301 MHz under liquid nitrogen, Luumi achieved a score of 10.8 cb, just edging out Strat's previous mark of 10.76 cb at 6,249 MHz. This result is roughly 66% above the chip's 3.8 GHz boost clock.
The leaderboard is tight, with Moose83 taking third place at 10.74 cb out of 187 total submissions. While this is a category record for the i5-4670K, it is not the overall Cinebench R11.5 world record. Luumi, known for extreme overclocking, previously set an 8-core world record on an EVGA Z390 Dark in 2018.
The build used a period-correct ASRock Z97 OC Formula motherboard, 4 GB of XPG DDR3 at 2,708 MT/s, and a Corsair AXi 1600 power supply, running on Windows 7 due to HWBot rules. Haswell chips are noted for high clocks; the Core i7-4770K was overclocked to 7 GHz at launch. A modern 12-core laptop scores roughly four times higher in R11.5, highlighting the achievement as maximizing the potential of 13-year-old silicon.
