Antitux hits 6528 MHz with Core i9-12900KF, claims y-cruncher - Pi-1b world record

An American overclocker, known as antitux, managed to secure first place in the y-cruncher - Pi-1b discipline with an Intel Core i9-12900KF processor.

During the benchmark, the 8-core chip hit 6528MHz, cooled by liquid nitrogen. The enthusiast paired the heavily overclocked CPU with DDR5 RAM, pushing it to a significant 6827MHz with CL30.0 40-40-28 timings, although not a record. Notably, all Gracemont E-cores of the Alder Lake architecture were deactivated.

It's also worth noting that disabling

the E-cores

, when paired with a compatible motherboard, enables AVX512 instructions on the larger Golden Cove P-cores. This significantly boosts their overall performance. The benchmark setup also included Intel's top-tier CPU alongside a robust GIGABYTE Z690 Aorus Tachyon motherboard (which, incidentally, supported AVX512 activation) and an NVIDIA GeForce GTX 1050 Ti 'placeholder' graphics card.
