Intel Core i5-12400
Six Golden Cove P-cores, no E-cores, and a 65 W base power budget — the chip that reset expectations for what a cheap 1080p gaming CPU should do. Its defining trait is that six fast cores are all most games ask for, so it lands within a handful of percent of parts costing three times more.
Pros
- Six full P-cores with Hyper-Threading at up to 4.4 GHz — enough for essentially every mainstream game
- 18 MB L3 gives noticeably better frame-time consistency than the 4-core i3 parts
- 65 W base / 117 W peak means a modest tower cooler is plenty, and the box cooler works
- UHD Graphics 730 iGPU covers display-out, QuickSync encoding, and GPU-less troubleshooting
- Same PCIe 5.0 x16 and DDR5-or-DDR4 flexibility as the expensive LGA1700 chips
Cons
- No E-cores, so heavily threaded rendering and compile jobs fall well behind a 12600K
- Locked multiplier — only memory tuning on Z-series, and even that is wasted money here
- 2.5 GHz base means sustained all-core work sits at modest clocks
- Superseded by the i5-13400 and its four extra E-cores at a similar street price
