You don’t need the latest and greatest PC hardware to have fun or even break overclocking world records. OC expert Luumi has demonstrated this very capably by achieving a new HWBot world record using an ancient Intel Core i5 4670K, a modest amount of DDR3, and (inevitably) a flask or two of LN2. Overclocker Luumi recently knocked the four-cores Intel Core i5 4670K Cinebench R11.5 record holder off their perch after 12 years, achieving a multicore score of 10.8 cb.

The HWBot-crowned system is built around Haswell-era Intel silicon, the Core i5 4670K to be precise. This is an unlocked 4C/4T CPU with a stock base/boost of 3.4 / 3.8 GHz, 84W TDP, with a 6MB cache and HD 4600 graphics, built on Intel’s 22nm process. You had to buy an i7 chip back in this era to get 4C/8T.

Luumi’s system hosted the CPU on an ASRock Z97 OC Formula motherboard, which was fitted with 4GB of DDR3 RAM from XPG, and fed ample power via a Corsair AXi 1600. To achieve the Cinebench R11.5 benchmark record liquid nitrogen was used to cool the 4670K, and the validation files show the CPU ran at a blistering 6,301.00 MHz.

5 score for any / all quad-core processors. It's just in the Core i5 4670K category. Nevertheless, it is great to see retro hardware achievements like this, 12 years later. As one other HWBot community member commented, it is brilliant to see an OC result on the HWBot homepage that involves neither an X3D CPU or RTX 5090 GPU .
