Performance comparison: which is faster?
Core i5-3570K (Intel, 2012) and Core i5-4590 (Intel, 2014) 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: i5-3570K is about 4.6% faster
The sockets differ (LGA1155 / LGA1150), 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 | i5-3570K | i5-4590 |
|---|---|---|
| Performance Score | 6,800 | 6,500 |
| Generation | 3rd Gen | 4th Gen |
| Socket | LGA1155 | LGA1150 |
| Release Year | 2012 | 2014 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Radeon RX 580 | GeForce GTX 1650 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i5-3570K |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i5-4590 (the lower model is often sufficient) |
i5-3570K is about 4.6% higher by score (i5-3570K: 6800 points / i5-4590: 6500 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.
i5-3570K is 3rd Gen, while i5-4590 is 4th Gen.The sockets differ (LGA1155 / LGA1150), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 580 pairs well with i5-3570K and GeForce GTX 1650 pairs well with i5-4590. If either GPU is too strong or too weak, one part holds the other back.
