Performance comparison: which is faster?
Core i3-8350K (Intel, 2018) and Core i7-2700K (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: nearly equal
The sockets differ (LGA1151 / 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 | i3-8350K | i7-2700K |
|---|---|---|
| Performance Score | 8,500 | 8,500 |
| Generation | 8th Gen | 2nd Gen |
| Socket | LGA1151 | LGA1155 |
| Release Year | 2018 | 2011 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Radeon RX 5500 XT | Radeon RX 5500 XT |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i3-8350K |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i3-8350K (the lower model is often sufficient) |
Their scores are nearly identical (i3-8350K: 8500 points / i7-2700K: 8500 points). Choose the less expensive option or the one that fits your current motherboard.
i3-8350K is 8th Gen, while i7-2700K is 2nd Gen.The sockets differ (LGA1151 / LGA1155), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 5500 XT pairs well with i3-8350K and Radeon RX 5500 XT pairs well with i7-2700K. If either GPU is too strong or too weak, one part holds the other back.
