Intel’s K-series desktop CPUs always get the most attention from enthusiasts because they represent the best performance that new Intel processors are capable of when money, heat, and power are no object. But more people will end up using the cheaper, non-overclockable versions of these processors, whether it’s in an office desktop PC, a budget gaming desktop, or a price-conscious home video editing workstation.

Today, we’re taking a look at the Core i7-12700, a 12-core, 20-thread CPU that retails for around $340 (or $315 without integrated graphics). That’s anywhere from $75 to $100 cheaper than the overclockable Core i7-12700K, plus whatever money you save by buying a cheaper H670 or B660 motherboard rather than a pricey Z690 model.

We came away impressed with the i7-12700's performance but mixed on its power efficiency, as was the case when we reviewed some K-series CPUs last year. The good news is that home PC builders can usually decide for themselves whether they want to maximize performance or prioritize power efficiency and heat output. Using Intel's recommended power settings, the i7-12700 can actually be quite well-behaved. Just know that most motherboard makers' default power settings prioritize performance even if it makes your desktop hotter and more power-hungry.
