Performance comparison: which is faster?
Core i5-4590 (Intel, 2014) and Core i5-2500K (Intel, 2011) 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: i5-4590 is about 4.8% faster
The sockets differ (LGA1150 / LGA1155), 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 | i5-4590 | i5-2500K |
|---|---|---|
| Performance Score | 6,500 | 6,200 |
| Generation | 4th Gen | 2nd Gen |
| Socket | LGA1150 | LGA1155 |
| Release Year | 2014 | 2011 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce GTX 1650 | GeForce GTX 1650 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i5-4590 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i5-2500K (the lower model is often sufficient) |
i5-4590 is about 4.8% higher by score (i5-4590: 6500 points / i5-2500K: 6200 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.
i5-4590 is 4th Gen, while i5-2500K is 2nd Gen.The sockets differ (LGA1150 / LGA1155), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, GeForce GTX 1650 pairs well with i5-4590 and GeForce GTX 1650 pairs well with i5-2500K. If either GPU is too strong or too weak, one part holds the other back.
