You really don’t need the latest silicon monster to have fun with overclocking. Luumi, a well-known HWBot overclocker, has just proven that an “ancient” Intel Core i5-4670K can still write history.

Using this Haswell-era quad-core, a bit of DDR3, and a lot of liquid nitrogen (LN2), Luumi set a new HWBot Cinebench R11.5 record for the Core i5-4670K category with a 10.8 cb multicore score.
The record-breaking setup
The heart of the system is an unlocked Core i5-4670K:
- 4C/4T, stock 3.4 / 3.8 GHz
- 22 nm process, 84 W TDP
- 6 MB cache, HD 4600 graphics
Back in the Haswell days you had to buy a Core i7 to get 4C/8T, so the 4670K was the classic “budget overclocker’s chip.”
Luumi mounted the CPU on an ASRock Z97 OC Formula motherboard, paired with 4 GB of XPG DDR3 RAM and powered by a Corsair AXi 1600 PSU. For the Cinebench R11.5 run, the CPU was cooled with LN2, and the validation files show an eye‑watering 6,301.00 MHz core clock.
To be clear, this isn’t the all-time global R11.5 record for every quad-core CPU; it’s the best result specifically for the Core i5-4670K on HWBot. Still, seeing retro hardware take headlines again after 12 years is refreshing—especially when, as one community member noted, the front page isn’t dominated by an X3D CPU or RTX 5090.
Old benchmarks on new systems
Out of curiosity, the author ran Cinebench R11.5 on a modern 12C/24T laptop. Even in a cool/quiet profile, it scored about 4× higher than Luumi’s record-breaking Haswell desktop—no surprise given the generational gap.
What’s interesting is that this old benchmark still runs fine on Windows 11, while some classic 3DMark DX10‑era tests no longer behave well enough for valid HWBot submissions. For the record attempt, Luumi stuck with Windows 7 64-bit Pro, a tried-and-true environment for legacy benchmarking.
