The Intel Core i5-10600K is currently retailing for $289.99 and $299.99 respectively on Amazon and Newegg which is well above Intel's suggested MSRP of just $262. This has created a bizarre situation where it is currently cheaper to purchase the CPU from Silicon Lottery where it has been verified to overclock to a set amount. Silicon Lottery sells multiple binned variants of the chip ranging from 4.7 GHz - 5.1 GHz max all-core overclock. Silicon Lottery will sell you a chip for $299.99 which is guaranteed to overclock to 4.9 GHz on all 6 cores, and 5.0 GHz on up to 2 cores.
This guaranteed all core overclock provides a significant performance boost over the stock base frequency of 4.1 GHz, which equates to roughly 1% - 3% gaming performance boost which while not massive still equates to a few extra FPS. If considering one of these CPUs keep in mind the need for reasonable aftermarket cooling to ensure these chips stay cool such as the Noctua NH-U12S we used in our review .
