Intel Core i7-12700K
Eight Golden Cove P-cores at 5.0 GHz plus a four-core E-core cluster, with 25 MB of L3 — Alder Lake's mainstream flagship below the i9. It is the point where LGA1700 stops being a budget platform and starts demanding a serious cooler and a decent VRM.
Pros
- 12 cores / 20 threads and 25 MB L3 handle gaming and heavy content work on one machine
- 5.0 GHz peak boost put it at the front of the single-thread charts at launch
- UHD Graphics 770 iGPU provides display-out and QuickSync encode alongside a discrete GPU
- Unlocked multiplier plus unlocked memory on Z-series boards
- Not affected by the Raptor Lake Vmin-shift degradation issue that hit 13th/14th gen i7/i9 parts
Cons
- 190 W maximum turbo power needs a large air cooler or a 240 mm AIO, and none is included
- No bundled cooler and a real jump in board cost over a B660-plus-i5 build
- Only marginally faster than an i5-12600KF in games despite costing far more
- E-core scheduling still misbehaves on Windows 10 and some older software
