Performance comparison: which is faster?
Core i3-9100 (Intel, 2019) and Core i5-6600 (Intel, 2016) 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
Both use the same LGA1151 socket, so they can be installed on the same motherboard. 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 | i3-9100 | i5-6600 |
|---|---|---|
| Performance Score | 7,800 | 7,800 |
| Generation | 9th Gen | 6th Gen |
| Socket | LGA1151 | LGA1151 |
| Release Year | 2019 | 2016 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce GTX 1650 SUPER | GeForce GTX 1650 SUPER |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i3-9100 |
| Upgrade while reusing the current motherboard | Either works (same LGA1151 socket) |
| Prioritize value and adequate performance | i3-9100 (the lower model is often sufficient) |
Their scores are nearly identical (i3-9100: 7800 points / i5-6600: 7800 points). Choose the less expensive option or the one that fits your current motherboard.
i3-9100 is 9th Gen, while i5-6600 is 6th Gen.Both use the same LGA1151 socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, GeForce GTX 1650 SUPER pairs well with i3-9100 and GeForce GTX 1650 SUPER pairs well with i5-6600. If either GPU is too strong or too weak, one part holds the other back.
