Performance comparison: which is faster?
Core i5-12600K (Intel, 2022) and Core i9-11900K (Intel, 2021) 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 (LGA1700 / LGA1200), 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 | i5-12600K | i9-11900K |
|---|---|---|
| Performance Score | 28,000 | 28,000 |
| Generation | 12th Gen | 11th Gen |
| Socket | LGA1700 | LGA1200 |
| Release Year | 2022 | 2021 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce RTX 5060 Ti | Radeon RX 7800 XT |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i5-12600K |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i5-12600K (the lower model is often sufficient) |
Their scores are nearly identical (i5-12600K: 28000 points / i9-11900K: 28000 points). Choose the less expensive option or the one that fits your current motherboard.
i5-12600K is 12th Gen, while i9-11900K is 11th Gen.The sockets differ (LGA1700 / LGA1200), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 5060 Ti pairs well with i5-12600K and Radeon RX 7800 XT pairs well with i9-11900K. If either GPU is too strong or too weak, one part holds the other back.
