Performance comparison: which is faster?
Core i9-11900 (Intel, 2021) and Core i9-10900 (Intel, 2020) 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 2% faster
Both use the same LGA1200 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 | i9-11900 | i9-10900 |
|---|---|---|
| Performance Score | 25,500 | 25,000 |
| Generation | 11th Gen | 10th Gen |
| Socket | LGA1200 | LGA1200 |
| Release Year | 2021 | 2020 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce RTX 5060 Ti | Radeon RX 7800 XT |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i9-11900 |
| Upgrade while reusing the current motherboard | Either works (same LGA1200 socket) |
| Prioritize value and adequate performance | i9-10900 (the lower model is often sufficient) |
i9-11900 is about 2% higher by score (i9-11900: 25500 points / i9-10900: 25000 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 i9-10900 is 10th Gen.Both use the same LGA1200 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 i9-11900 and Radeon RX 7800 XT pairs well with i9-10900. If either GPU is too strong or too weak, one part holds the other back.
