Performance comparison: which is faster?
AMD A10-7850K (AMD, 2014) and AMD A8-7670K (AMD, 2015) 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: A10-7850K is about 15.6% faster
Both use the same FM2+ 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 | A10-7850K | A8-7670K |
|---|---|---|
| Performance Score | 5,200 | 4,500 |
| Generation | A-Series | A-Series |
| Socket | FM2+ | FM2+ |
| Release Year | 2014 | 2015 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Radeon RX 6500 XT | Radeon RX 6400 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | A10-7850K |
| Upgrade while reusing the current motherboard | Either works (same FM2+ socket) |
| Prioritize value and adequate performance | A8-7670K (the lower model is often sufficient) |
A10-7850K is about 15.6% higher by score (A10-7850K: 5200 points / A8-7670K: 4500 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 A-Series-generation CPUs.Both use the same FM2+ socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 6500 XT pairs well with A10-7850K and Radeon RX 6400 pairs well with A8-7670K. If either GPU is too strong or too weak, one part holds the other back.
