Performance comparison: which is faster?
Ryzen 7 5800X (AMD, 2021) and Ryzen 7 8700G (AMD, 2024) 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 5800X is about 3.3% faster
The sockets differ (AM4 / AM5), 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 | Ryzen 7 5800X | Ryzen 7 8700G |
|---|---|---|
| Performance Score | 31,000 | 30,000 |
| Generation | Ryzen 5000 | Ryzen 8000 |
| Socket | AM4 | AM5 |
| Release Year | 2021 | 2024 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Radeon RX 7800 XT | Radeon RX 6950 XT |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | Ryzen 7 5800X |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | Ryzen 7 8700G (the lower model is often sufficient) |
Ryzen 7 5800X is about 3.3% higher by score (Ryzen 7 5800X: 31000 points / Ryzen 7 8700G: 30000 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 5800X is Ryzen 5000, while Ryzen 7 8700G is Ryzen 8000.The sockets differ (AM4 / AM5), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 7800 XT pairs well with Ryzen 7 5800X and Radeon RX 6950 XT pairs well with Ryzen 7 8700G. If either GPU is too strong or too weak, one part holds the other back.
