Performance comparison: which is faster?
Core i3-12100 (Intel, 2022) and Core i5-9600K (Intel, 2019) 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 / LGA1151), 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 | i3-12100 | i5-9600K |
|---|---|---|
| Performance Score | 13,500 | 13,500 |
| Generation | 12th Gen | 9th Gen |
| Socket | LGA1700 | LGA1151 |
| Release Year | 2022 | 2019 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Radeon RX 6800 | GeForce RTX 4060 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i3-12100 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i3-12100 (the lower model is often sufficient) |
Their scores are nearly identical (i3-12100: 13500 points / i5-9600K: 13500 points). Choose the less expensive option or the one that fits your current motherboard.
i3-12100 is 12th Gen, while i5-9600K is 9th Gen.The sockets differ (LGA1700 / LGA1151), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 6800 pairs well with i3-12100 and GeForce RTX 4060 pairs well with i5-9600K. If either GPU is too strong or too weak, one part holds the other back.
