Performance comparison: which is faster?
Core i5-12600KF (Intel, 2022) and Core i5-12400 (Intel, 2022) are compared here. Compare not only scores, but also whether the motherboard can be reused and which GPU class is balanced with each CPU.
Overall performance: i5-12600KF is about 41% faster
Both use the same LGA1700 socket, so they can be installed on the same motherboard. For games, performance balance with the GPU (guideline CPU:GPU = 0.9:1) matters more than CPU speed alone.
Relative performance score (higher is faster). Actual speed varies by workload, cooling, and memory configuration.
| Item | i5-12600KF | i5-12400 |
|---|---|---|
| Performance Score | 27,500 | 19,500 |
| Generation | 12th Gen | 12th Gen |
| Socket | LGA1700 | LGA1700 |
| Release Year | 2022 | 2022 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce RTX 5060 Ti | GeForce RTX 5060 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i5-12600KF |
| Upgrade while reusing the current motherboard | Either works (same LGA1700 socket) |
| Prioritize value and adequate performance | i5-12400 (the lower model is often sufficient) |
i5-12600KF is about 41% higher by score (i5-12600KF: 27500 points / i5-12400: 19500 points). For gaming, the GPU tier usually matters more than a few percent of CPU difference. For CPU-heavy work such as video editing and streaming, choose the faster CPU.
Both are 12th Gen-generation CPUs.Both use the same LGA1700 socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 5060 Ti pairs well with i5-12600KF and GeForce RTX 5060 pairs well with i5-12400. If either GPU is too strong or too weak, one part holds the other back.
