Performance comparison: which is faster?
Core i7-13700K (Intel, 2023) and Core i9-12900K (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: i7-13700K is about 9.5% 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 | i7-13700K | i9-12900K |
|---|---|---|
| Performance Score | 46,000 | 42,000 |
| Generation | 13th Gen | 12th Gen |
| Socket | LGA1700 | LGA1700 |
| Release Year | 2023 | 2022 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce RTX 5070 | GeForce RTX 3090 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i7-13700K |
| Upgrade while reusing the current motherboard | Either works (same LGA1700 socket) |
| Prioritize value and adequate performance | i9-12900K (the lower model is often sufficient) |
i7-13700K is about 9.5% higher by score (i7-13700K: 46000 points / i9-12900K: 42000 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.
i7-13700K is 13th Gen, while i9-12900K is 12th 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 5070 pairs well with i7-13700K and GeForce RTX 3090 pairs well with i9-12900K. If either GPU is too strong or too weak, one part holds the other back.
