Luumi Sets New Cinebench Record With Intel Core i5
The overclocker pushed an Intel processor to 6,301MHz using liquid nitrogen to secure the top spot.
Updated on Oct. 19, 2026 in Computers
Overclocker Luumi has set a new record in the Cinebench R11.5 benchmark by achieving a score of 10.80 points. The performance was driven by an Intel Core i5-4670K processor operating at 6,301MHz.
Why it matters
This achievement highlights the extreme performance ceiling of older hardware when paired with specialized cooling techniques. It breaks a long-standing benchmark record held by another user since 2014.
The processor reached a frequency of 6,301MHz, which is a 66% overclock above the 3.8GHz boost clock. The test rig utilized an ASRock Z97 OC Formula motherboard, 4GB of XPG DDR3 memory, and Windows 7 Professional 64-bit.

Timeline
October 24, 2014: Previous record was established by Strat.
October 19, 2026: Luumi set the new benchmark record.
The Tech Race
This achievement demonstrates the continued relevance of the Haswell-era Intel architecture within niche performance enthusiast communities. It underscores the ongoing competition among overclockers to extract maximum efficiency from legacy hardware versus newer, more complex silicon.
While this extreme performance does not affect standard consumer workflows, it demonstrates the physical limits of aging silicon. Users with similar older systems can see the potential for hardware longevity through manual frequency tuning.
The takeaway
Pushing hardware to these extremes shows how much overhead manufacturers often include in their factory settings. Enthusiasts should note that such extreme cooling methods are required to bypass standard thermal protections safely.
