Performance comparison: which is faster?
Ryzen 7 1700X (AMD, 2017) and Ryzen 3 3100 (AMD, 2020) 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: Ryzen 7 1700X is about 11.5% faster
Both use the same AM4 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 | Ryzen 7 1700X | Ryzen 3 3100 |
|---|---|---|
| Performance Score | 14,500 | 13,000 |
| Generation | Ryzen 1000 | Ryzen 3000 |
| Socket | AM4 | AM4 |
| Release Year | 2017 | 2020 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Intel Arc B570 | GeForce RTX 5050 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | Ryzen 7 1700X |
| Upgrade while reusing the current motherboard | Either works (same AM4 socket) |
| Prioritize value and adequate performance | Ryzen 3 3100 (the lower model is often sufficient) |
Ryzen 7 1700X is about 11.5% higher by score (Ryzen 7 1700X: 14500 points / Ryzen 3 3100: 13000 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.
Ryzen 7 1700X is Ryzen 1000, while Ryzen 3 3100 is Ryzen 3000.Both use the same AM4 socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, Intel Arc B570 pairs well with Ryzen 7 1700X and GeForce RTX 5050 pairs well with Ryzen 3 3100. If either GPU is too strong or too weak, one part holds the other back.
