Performance comparison: which is faster?
Core i9-11900 (Intel, 2021) and Core i5-14400F (Intel, 2024) 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: i9-11900 is about 4.1% faster
The sockets differ (LGA1200 / LGA1700), 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 | i9-11900 | i5-14400F |
|---|---|---|
| Performance Score | 25,500 | 24,500 |
| Generation | 11th Gen | 14th Gen |
| Socket | LGA1200 | LGA1700 |
| Release Year | 2021 | 2024 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce RTX 5060 Ti | GeForce RTX 5060 Ti |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i9-11900 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i5-14400F (the lower model is often sufficient) |
i9-11900 is about 4.1% higher by score (i9-11900: 25500 points / i5-14400F: 24500 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.
i9-11900 is 11th Gen, while i5-14400F is 14th Gen.The sockets differ (LGA1200 / LGA1700), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 5060 Ti pairs well with i9-11900 and GeForce RTX 5060 Ti pairs well with i5-14400F. If either GPU is too strong or too weak, one part holds the other back.
