Performance comparison: which is faster?
Core i9-12900 (Intel, 2022) and Core i5-13600KF (Intel, 2023) 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: i9-12900 is about 1.3% 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 | i9-12900 | i5-13600KF |
|---|---|---|
| Performance Score | 38,000 | 37,500 |
| Generation | 12th Gen | 13th Gen |
| Socket | LGA1700 | LGA1700 |
| Release Year | 2022 | 2023 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce RTX 5060 Ti | GeForce RTX 3090 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i9-12900 |
| Upgrade while reusing the current motherboard | Either works (same LGA1700 socket) |
| Prioritize value and adequate performance | i5-13600KF (the lower model is often sufficient) |
i9-12900 is about 1.3% higher by score (i9-12900: 38000 points / i5-13600KF: 37500 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.
i9-12900 is 12th Gen, while i5-13600KF is 13th Gen.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 i9-12900 and GeForce RTX 3090 pairs well with i5-13600KF. If either GPU is too strong or too weak, one part holds the other back.
