Performance comparison: which is faster?
Core i3-2100 (Intel, 2011) and Core i3-560 (Intel, 2010) 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: i3-2100 is about 7.1% faster
The sockets differ (LGA1155 / LGA1156), 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 | i3-2100 | i3-560 |
|---|---|---|
| Performance Score | 3,000 | 2,800 |
| Generation | 2nd Gen | 1st Gen |
| Socket | LGA1155 | LGA1156 |
| Release Year | 2011 | 2010 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce GTX 1030 | GeForce GTX 1030 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i3-2100 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i3-560 (the lower model is often sufficient) |
i3-2100 is about 7.1% higher by score (i3-2100: 3000 points / i3-560: 2800 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.
i3-2100 is 2nd Gen, while i3-560 is 1st Gen.The sockets differ (LGA1155 / LGA1156), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, GeForce GTX 1030 pairs well with i3-2100 and GeForce GTX 1030 pairs well with i3-560. If either GPU is too strong or too weak, one part holds the other back.
