Overclocker Luumi set a new Cinebench R11.5 record for the Intel Core i5-4670K by achieving a score of 10.8 cb. The 2013 Haswell processor was pushed to 6,301 MHz using liquid nitrogen cooling, exceeding the previous record of 10.76 cb held by Strat at 6,249 MHz. This marks the first time the i5-4670K category has seen a new benchmark in over 12 years.
The overclocking setup included an ASRock Z97 OC Formula motherboard, 4 GB of XPG DDR3 memory running at 2,708 MT/s, and a Corsair AXi 1600 power supply. The test was conducted on Windows 7, as HWBot's R11.5 rules apparently restrict pre-Skylake Intel chips on newer Windows versions without BenchMate. Luumi's achievement highlights extreme clocking of 13-year-old silicon, with the chip's base clock of 3.4 GHz and boost clock of 3.8 GHz significantly exceeded.
Luumi's record surpasses other i5-4670K submissions, with Moose83 holding third place at 10.74 cb. While the achievement is notable for its category, modern 12-core laptops reportedly score around four times higher in R11.5 when running in quiet mode. The overclocking community continues to explore limits of older hardware, with the i7-4770K previously reaching 7 GHz in 2013. This record remains specific to the i5-4670K category, not an overall Cinebench R11.5 world record.
