Performance comparison: which is faster?
Core i7-7700 (Intel, 2017) and Core i3-7100 (Intel, 2017) 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: i7-7700 is about 109.1% faster
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 | i7-7700 | i3-7100 |
|---|---|---|
| Performance Score | 11,500 | 5,500 |
| Generation | 7th Gen | 7th Gen |
| Socket | LGA1151 | LGA1151 |
| Release Year | 2017 | 2017 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce RTX 2080 SUPER | Radeon RX 470 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i7-7700 |
| Upgrade while reusing the current motherboard | Either works (same LGA1151 socket) |
| Prioritize value and adequate performance | i3-7100 (the lower model is often sufficient) |
i7-7700 is about 109.1% higher by score (i7-7700: 11500 points / i3-7100: 5500 points). For gaming, the GPU tier usually matters more than a few percent of CPU difference. For CPU-heavy work such as video editing and streaming, choose the faster CPU.
Both are 7th Gen-generation CPUs.Both use the same LGA1151 socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 2080 SUPER pairs well with i7-7700 and Radeon RX 470 pairs well with i3-7100. If either GPU is too strong or too weak, one part holds the other back.
