Intel - Core i9-14900K vs Intel - Core Ultra 5 245K

The Core i9-14900K is the clear pick on raw spec strength, leading by 9.2 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.

Pick the Core i9-14900K if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. The biggest gaps in its favor are cores, cinebench r23 (multi), l3 cache, among others.
