Performance comparison: which is faster?
Core i3-12100F (Intel, 2022) and Core i5-10400F (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: i3-12100F is about 3.9% faster
The sockets differ (LGA1700 / LGA1200), 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 | i3-12100F | i5-10400F |
|---|---|---|
| Performance Score | 13,300 | 12,800 |
| Generation | 12th Gen | 10th Gen |
| Socket | LGA1700 | LGA1200 |
| Release Year | 2022 | 2020 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Radeon RX 7700 XT | Radeon RX 6700 XT |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i3-12100F |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i5-10400F (the lower model is often sufficient) |
i3-12100F is about 3.9% higher by score (i3-12100F: 13300 points / i5-10400F: 12800 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.
i3-12100F is 12th Gen, while i5-10400F is 10th Gen.The sockets differ (LGA1700 / LGA1200), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 7700 XT pairs well with i3-12100F and Radeon RX 6700 XT pairs well with i5-10400F. If either GPU is too strong or too weak, one part holds the other back.
