Overclocker Luumi has taken down a Cinebench R11.5 record that had stood for 12 years, according to Tom's Hardware. The winning system was built around an Intel Core i5-4670K, a Haswell-era quad-core chip that normally runs at 3.4 GHz base and 3.8 GHz boost. With liquid nitrogen cooling, Luumi pushed the CPU to 6,301 MHz and scored 10.8 cb in the multicore test.
The rest of the setup was appropriately retro: an ASRock Z97 OC Formula motherboard, 4GB of XPG DDR3, a Corsair AXi 1600 power supply, and Windows 7 64-bit Pro. Tom's Hardware notes that the record is specific to the Core i5-4670K category on HWBot, not a general quad-core Cinebench record. Still, the result stands out in an overclocking scene often dominated by the latest X3D chips and RTX 5090 GPUs.
The article also points out that a modern 12-core laptop CPU can easily quadruple the old Haswell chip's score, even in a quiet power mode. But the achievement is less about raw performance and more about what dedicated overclockers can still squeeze from decade-old hardware with the right board, memory, and a flask or two of liquid nitrogen.
