Cinebench world record that stood for 12 years gets toppled — OC expert scores 10.8cb in Cinebench R11.5 using an Intel Core i5 4670K at 6.3 GHz Overclocking enthusiasts are still having fun with Haswell CPUs and DDR3 in 2026. 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. Again, we’ll comment that this isn’t a world record Cinebench R11.5 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. You don’t need the latest, greatest, most expensive, nor unobtainuim components to get featured on the online home of competitive overclocking. Out of curiosity I decided to give ye olde Cinebench R11.5 a spin on the laptop I’m currently working on. With its 12C/24T CPU, it trounced the old-but-record-breaking Haswell desktop, of course. Even though the laptop is running in cool/quiet mode I achieved 4x the 4670K score. Mostly I was happy that this older version of Cinebench still works on modern hardware and Windows 11 without any fuss. Some apps which were popular benchmarking staples, like 3DMark tests from DX10 and earlier eras, have issues on modern computers making the results you can wheedle out of them invalid for HWBot rankings. Luumi used Windows 7 64-bit Pro for their Haswell CPU Cinebench R11.5 testing.

The title should've mentioned Haswell, IMO. Anyway, I still have a Haswell box, with a Refresh i3 in it. I never really used it for the intended purpose, but I have some ideas for it. Temps ran higher than I expected, so I bought a delidding tool last year to see what I could do about that. I had already lapped both the CPU and heatsink, so I was a bit surprised at how warm it still ran. Maybe I'll get around to the delid, this winter. Reply
