Performance comparison: which is faster?
Core i7-10700KF (Intel, 2020) and Core i9-9900K (Intel, 2019) 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: i7-10700KF is about 1.4% faster
The sockets differ (LGA1200 / LGA1151), so switching requires a motherboard replacement. 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 | i7-10700KF | i9-9900K |
|---|---|---|
| Performance Score | 21,800 | 21,500 |
| Generation | 10th Gen | 9th Gen |
| Socket | LGA1200 | LGA1151 |
| Release Year | 2020 | 2019 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce RTX 4060 Ti | GeForce RTX 5060 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i7-10700KF |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i9-9900K (the lower model is often sufficient) |
i7-10700KF is about 1.4% higher by score (i7-10700KF: 21800 points / i9-9900K: 21500 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.
i7-10700KF is 10th Gen, while i9-9900K is 9th Gen.The sockets differ (LGA1200 / LGA1151), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 4060 Ti pairs well with i7-10700KF and GeForce RTX 5060 pairs well with i9-9900K. If either GPU is too strong or too weak, one part holds the other back.
