Intel Core i9-14900KS is 62% hungrier than its predecessor

The 'S' stands for Supernova.

Intel Core i9-14900KS specs have been a mystery for quite a while now. Fortunately, we now know what’s under the hood thanks to a benchmark leak. It looks like the upcoming flagship chip surpasses the 14900K’s turbo clock by 200MHz, raising the bar to 6.2GHz. Nothing comes for free, however. The new chip demands an additional 25W to power it, resulting in a 150W TDP.

More importantly, with power limits unlocked, this beastly processor can potentially pull around 409W from the wall. That’s a massive 61.6% more than 14900K’s max-rated power draw. Sheesh! Fortunately, it’s only for a short duration. You’re not likely to get that much out of it consistently.

The juicy details come from OCCT benchmark, and the chip in question is a production unit. It’s not a mere engineering sample, but something you could pick off store shelves in the near future.

Nonetheless, the 14900KS mirrors the 14900K and boasts 24 cores and 32 threads, split between eight performance cores and 16 efficiency cores. Intel didn’t bother tinkering with the caches either, so expect the same combined L2+L3 cache pool of 68MB. It’s slightly disappointing, seeing as AMD released a cache-heavy last-gen gem in 2024.

Intel seeks to cement dominance by cranking up the power. A tale as old as time. In this specific setup, the testers amped up the power limit to the maximum of 4000W to ensure the CPU operates without any restrictions. The chip was benchmarked on an MSI MAG Z790 Tomahawk Wi-Fi motherboard mated to 32GB of DDR5 memory and a T-Force TM8FPZ002T M.2 NVMe SSD.

OCCT measured an eyewatering 409W power draw, with a max CPU temperature of 99.5°C during a short 11-second burst. Unfortunately, we can’t conclude much else due to this short-duration test. Besides, imagine the electric bill if you manage to use it at that power draw for a full gaming session.

Intel has yet to officially announce Core i9-14900KS or its release date. Based on its predecessors – the i9-12900KS and i9-13900KS – we could see a similar release window anywhere between now and April. Hmm, do you think it’s worthy of our best CPU list?
