Intel Core i5-12600K
A 10-core, 16-thread hybrid chip — 6 Golden Cove performance cores and 4 Gracemont efficiency cores — that cost roughly half the i9-12900K while staying close to it in games. It opened Intel's 12th Gen mid-range line on the new LGA1700 socket with DDR5 and PCIe 5.0 support, though the platform has since moved through two further Core generations.
Pros
- 6 P-cores plus 4 E-cores matched or beat 8-core, previous-generation chips in games at a mid-range price
- Unlocked multiplier with independent P-core and E-core ratio control for tuning
- Supports either DDR4-3200 or DDR5-4800 boards, letting buyers pick the cheaper platform
- Integrated UHD Graphics 770 removes the need for a discrete GPU for basic use
- 150 W maximum turbo power is easier to cool than the flagship i9 of the same generation
Cons
- No cooler included in the box, unlike the locked, lower-tier i5-12400
- E-cores lack Hyper-Threading and AVX-512, and early Windows 10 systems scheduled threads onto them poorly
- LGA1700 has since moved through two further Core generations, so a used board has no CPU upgrade path beyond 14th Gen
- 20 MB of L3 cache is 10 MB less than the i9-12900K, narrowing headroom in heavily multi-threaded work
