Performance comparison: which is faster?
Core i5-2500 (Intel, 2011) and Core i5-3450 (Intel, 2012) 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: i5-2500 is about 5.5% faster
Both use the same LGA1155 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 | i5-2500 | i5-3450 |
|---|---|---|
| Performance Score | 5,800 | 5,500 |
| Generation | 2nd Gen | 3rd Gen |
| Socket | LGA1155 | LGA1155 |
| Release Year | 2011 | 2012 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Radeon RX 570 | Radeon RX 470 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i5-2500 |
| Upgrade while reusing the current motherboard | Either works (same LGA1155 socket) |
| Prioritize value and adequate performance | i5-3450 (the lower model is often sufficient) |
i5-2500 is about 5.5% higher by score (i5-2500: 5800 points / i5-3450: 5500 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.
i5-2500 is 2nd Gen, while i5-3450 is 3rd Gen.Both use the same LGA1155 socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 570 pairs well with i5-2500 and Radeon RX 470 pairs well with i5-3450. If either GPU is too strong or too weak, one part holds the other back.
