Intel Core i5-4670K Breaks Cinebench R11.5 World Record 12 Years After Launch
Old hardware is still finding ways to surprise the PC overclocking community. More than a decade after Intel’s Haswell processors first arrived, an overclocker has pushed the Core i5-4670K to a new milestone, breaking a long-standing Cinebench R11.5 world record that had remained unbeaten for 12 years.
The achievement comes from well-known overclocker Luumi, who managed to drive the 2013-era Intel Core i5-4670K to an impressive 6.3 GHz using liquid nitrogen cooling. That extreme setup helped the chip score 10.8 points in Cinebench R11.5, setting a new category record for this classic Haswell processor.
What makes this result especially interesting is that the Core i5-4670K is far from modern by today’s standards. Released in 2013 as part of Intel’s fourth-generation Core lineup, the processor features four cores and four threads, 6 MB of cache, a 3.4 GHz base clock, and a 3.8 GHz boost clock. Built on Intel’s 22nm process, it was once a favorite among PC enthusiasts thanks to its unlocked multiplier and strong overclocking potential.
Before Luumi’s record-breaking run, the top Cinebench R11.5 score for the Core i5-4670K stood at 10.76 points, achieved at around 6.2 GHz. Several other overclockers had also pushed the processor beyond 10.5 points, but none had managed to cross the 10.8-point mark until now.
The Core i5-4670K has seen even higher clock speeds in the past, with frequency records exceeding 7.0 GHz as far back as 2013. However, raw frequency is only part of the story. Achieving a higher benchmark score requires stability, tuning, memory optimization, and the right combination of supporting hardware.
For this record attempt, Luumi used an ASRock Z97 OC Formula motherboard, a board designed with extreme overclocking in mind. The system also included 4 GB of XPG DDR3 memory running at 2,708 MT/s and a Corsair AX1600W power supply. Combined with liquid nitrogen cooling, the setup allowed the old Haswell chip to operate far beyond its original specifications.
While this is an exciting moment for overclocking fans, it is important to understand the context. This record applies to a specific benchmark category and processor class. It does not mean the Core i5-4670K is suddenly competitive with modern gaming CPUs or current workstation processors. In everyday use, especially in newer games and demanding applications, newer chips with more cores, more threads, and newer architectures will still offer much better performance.
Still, the result is a reminder of why classic PC hardware continues to attract attention. Overclockers often revisit older processors not because they are practical by today’s standards, but because they represent a challenge. Finding extra performance from a chip released over a decade ago requires deep technical knowledge, patience, and a willingness to experiment.
The Intel Core i5-4670K was already known as one of the standout enthusiast CPUs of its era. Now, 12 years later, it has added another achievement to its legacy with a fresh Cinebench R11.5 world record. For fans of extreme overclocking, this is proof that even aging hardware can still make headlines when placed in the right hands.
