Performance comparison: which is faster?
Core i7-2700K (Intel, 2011) and Core i7-980X (Intel, 2010) 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 (LGA1155 / LGA1156), 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 | i7-2700K | i7-980X |
|---|---|---|
| Performance Score | 8,500 | 8,500 |
| Generation | 2nd Gen | 1st Gen |
| Socket | LGA1155 | LGA1156 |
| Release Year | 2011 | 2010 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Radeon RX 5500 XT | GeForce GTX 980 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i7-2700K |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i7-2700K (the lower model is often sufficient) |
Their scores are nearly identical (i7-2700K: 8500 points / i7-980X: 8500 points). Choose the less expensive option or the one that fits your current motherboard.
i7-2700K is 2nd Gen, while i7-980X is 1st Gen.The sockets differ (LGA1155 / LGA1156), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 5500 XT pairs well with i7-2700K and GeForce GTX 980 pairs well with i7-980X. If either GPU is too strong or too weak, one part holds the other back.
