Performance comparison: which is faster?
AMD FX-6300 (AMD, 2012) and AMD Phenom II X6 1090T (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: FX-6300 is about 4.8% faster
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-6300 | Phenom II X6 1090T |
|---|---|---|
| Performance Score | 6,500 | 6,200 |
| Generation | FX | Phenom II |
| Socket | AM3+ | AM3 |
| Release Year | 2012 | 2010 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce GTX 1650 | GeForce GTX 1650 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | FX-6300 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | Phenom II X6 1090T (the lower model is often sufficient) |
FX-6300 is about 4.8% higher by score (FX-6300: 6500 points / Phenom II X6 1090T: 6200 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.
FX-6300 is FX, while Phenom II X6 1090T is Phenom II.The sockets differ (AM3+ / AM3), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, GeForce GTX 1650 pairs well with FX-6300 and GeForce GTX 1650 pairs well with Phenom II X6 1090T. If either GPU is too strong or too weak, one part holds the other back.
