Performance comparison: which is faster?
Core i9-12900KS (Intel, 2022) and Core i7-13700 (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: i9-12900KS is about 7.1% 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 | i9-12900KS | i7-13700 |
|---|---|---|
| Performance Score | 45,000 | 42,000 |
| Generation | 12th Gen | 13th Gen |
| Socket | LGA1700 | LGA1700 |
| Release Year | 2022 | 2023 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce RTX 3080 Ti | Radeon RX 6950 XT |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i9-12900KS |
| Upgrade while reusing the current motherboard | Either works (same LGA1700 socket) |
| Prioritize value and adequate performance | i7-13700 (the lower model is often sufficient) |
i9-12900KS is about 7.1% higher by score (i9-12900KS: 45000 points / i7-13700: 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.
i9-12900KS is 12th Gen, while i7-13700 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 3080 Ti pairs well with i9-12900KS and Radeon RX 6950 XT pairs well with i7-13700. If either GPU is too strong or too weak, one part holds the other back.
