i9-12900K
- The i9-12900K has higher Level 2 Cache. Data/instructions which have to be processed can be loaded from the fast L2 and the CPU does not have to wait for the very slow DDR RAM
i9-14900K
- The i9-14900K has higher Level 3 Cache. This is useful when you have substantial multiprocessing workloads, many computationally intense simultaneous processes. More likely on a server, less on a personally used computer for interactive desktop workloads.
