Performance comparison: which is faster?
Core i5-8500 (Intel, 2018) and Core i7-4790 (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: i5-8500 is about 2.9% faster
The sockets differ (LGA1151 / 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 | i5-8500 | i7-4790 |
|---|---|---|
| Performance Score | 10,800 | 10,500 |
| Generation | 8th Gen | 4th Gen |
| Socket | LGA1151 | LGA1150 |
| Release Year | 2018 | 2014 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce RTX 2080 SUPER | GeForce RTX 2060 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i5-8500 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i7-4790 (the lower model is often sufficient) |
i5-8500 is about 2.9% higher by score (i5-8500: 10800 points / i7-4790: 10500 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.
i5-8500 is 8th Gen, while i7-4790 is 4th Gen.The sockets differ (LGA1151 / LGA1150), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 2080 SUPER pairs well with i5-8500 and GeForce RTX 2060 pairs well with i7-4790. If either GPU is too strong or too weak, one part holds the other back.
