Intel Core i7-12700K Alder Lake CPU (2021)
Product Gallery
Product Overview
Intel Core i7-12700K is a premium desktop microprocessor based on Intel's 12th-gen Core Alder Lake architecture. Like the i5-12600K and i9-12900K unveiled at the same time, the i7-12700K features a new "hybrid" design, in this case with 8 performance cores and 4 efficiency cores.
With this hybrid design, Intel is able to offer a significant performance boost over the 11th-gen chips (notably the i7-11700K). At the same time, the move to the Intel 7 (10nm) process affords the i7-12700K more leeway in turbo performance: the CPU is able to stay at boost clock significantly longer than before, though it still consumes a lot of electricity while doing so.
The inclusion of efficiency cores, meanwhile, allows Intel to do away with "TDP down" mode: in situations where this were called for, the CPU simply runs the efficiency cores instead.
Other notable highlights include support for PCIe 5 and DDR5 memory, though compatible components remain rare and expensive.
Those who intend on installing their own discrete graphics card can opt for the i7-12700KF, which drops the integrated UHD 770 graphics but is otherwise identical.

Reviewer score 71%The Core i7-12700K is faster than its 11th Generation predecessor, but the degree to which performance has increased is rather impressive. It’s not quite as powerful as the Core i9-12900K for CPU-intensive tasks, and its performance gains aren’t substantial enough purely for gaming to recommend it. The Core i5-12600K might be a better option for a pure gaming build.

Pros
- Improved single-threaded performance
- New E-Cores
Cons
- Higher price than Core i9-12700K
- No integrated graphics

Reviewer score 77%The standard Core i7-12700K comes with the UHD Graphics 770 with 32 EUs that run at a 300 / 1500 MHz base/boost. You will lose Quick Sync capabilities and the iGPU fallback that you can use for troubleshooting in the event of an issue with a discrete graphics card. Intel's Alder Lake drops into Socket 1700 motherboards with the Z690 chipset.
