Performance comparison: which is faster?
AMD FX-4100 (AMD, 2012) and AMD Phenom II X4 965 (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: nearly equal
The sockets differ (AM3+ / AM3), 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 | FX-4100 | Phenom II X4 965 |
|---|---|---|
| Performance Score | 4,200 | 4,200 |
| Generation | FX | Phenom II |
| Socket | AM3+ | AM3 |
| Release Year | 2012 | 2010 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce GTX 1050 | GeForce GTX 1050 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | FX-4100 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | FX-4100 (the lower model is often sufficient) |
Their scores are nearly identical (FX-4100: 4200 points / Phenom II X4 965: 4200 points). Choose the less expensive option or the one that fits your current motherboard.
FX-4100 is FX, while Phenom II X4 965 is Phenom II.The sockets differ (AM3+ / AM3), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, GeForce GTX 1050 pairs well with FX-4100 and GeForce GTX 1050 pairs well with Phenom II X4 965. If either GPU is too strong or too weak, one part holds the other back.
