The Intel Core i5-4670K, a quad-core processor released in 2013, has achieved a new performance record in the Cinebench R11.5 benchmark. Overclocker Luumi secured the top spot on the HWBot leaderboard for this specific chip, surpassing a record that had remained unchallenged for approximately 12 years.
To reach this milestone, Luumi pushed the Haswell-based CPU to a frequency of 6,301 MHz, which represents a significant increase over the processor's original 3.8 GHz boost clock. The feat was accomplished using liquid nitrogen cooling to maintain stability at these extreme speeds. The resulting score of 10.8 cb narrowly edged out the previous record of 10.76 cb, which was held by an overclocker known as Strat.
The test setup utilized period-correct hardware, including an ASRock Z97 OC Formula motherboard, which was previously used to push the Core i7-4790K beyond 7 GHz in 2014. The system was equipped with 4 GB of XPG DDR3 memory running at 2,708 MT/s with 8-12-7-28 timings and powered by a Corsair AXi 1600 power supply. The benchmark was conducted on Windows 7, as HWBot rules for pre-Skylake Intel chips require this environment unless using BenchMate.
While this achievement highlights the overclocking potential of 22 nm Haswell silicon, it remains a category-specific record rather than an overall world record for Cinebench R11.5. The i5-4670K, which features four cores and four threads, continues to be a subject of experimentation for enthusiasts looking to extract maximum performance from older hardware, even if such gains offer limited practical benefits for modern gaming applications.
