Performance comparison: which is faster?
AMD Athlon II X3 445 (AMD, 2010) and AMD Athlon II X2 250 (AMD, 2010) 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: Athlon II X3 445 is about 30% faster
Both use the same AM3 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 | Athlon II X3 445 | Athlon II X2 250 |
|---|---|---|
| Performance Score | 2,600 | 2,000 |
| Generation | Athlon II | Athlon II |
| Socket | AM3 | AM3 |
| Release Year | 2010 | 2010 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce GTX 650 Ti | GeForce GTX 650 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | Athlon II X3 445 |
| Upgrade while reusing the current motherboard | Either works (same AM3 socket) |
| Prioritize value and adequate performance | Athlon II X2 250 (the lower model is often sufficient) |
Athlon II X3 445 is about 30% higher by score (Athlon II X3 445: 2600 points / Athlon II X2 250: 2000 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 Athlon II-generation CPUs.Both use the same AM3 socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, GeForce GTX 650 Ti pairs well with Athlon II X3 445 and GeForce GTX 650 pairs well with Athlon II X2 250. If either GPU is too strong or too weak, one part holds the other back.
