Performance comparison: which is faster?
Core i5-11400 (Intel, 2021) and Core i7-9700 (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: nearly equal
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 | i5-11400 | i7-9700 |
|---|---|---|
| Performance Score | 15,500 | 15,500 |
| Generation | 11th Gen | 9th Gen |
| Socket | LGA1200 | LGA1151 |
| Release Year | 2021 | 2019 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Radeon RX 7700 XT | Radeon RX 7700 XT |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i5-11400 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i5-11400 (the lower model is often sufficient) |
Their scores are nearly identical (i5-11400: 15500 points / i7-9700: 15500 points). Choose the less expensive option or the one that fits your current motherboard.
i5-11400 is 11th Gen, while i7-9700 is 9th Gen.The sockets differ (LGA1200 / LGA1151), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 7700 XT pairs well with i5-11400 and Radeon RX 7700 XT pairs well with i7-9700. If either GPU is too strong or too weak, one part holds the other back.
