Performance comparison: which is faster?
AMD A10-7890K (AMD, 2016) and AMD Phenom II X6 1055T (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 (FM2+ / 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 | A10-7890K | Phenom II X6 1055T |
|---|---|---|
| Performance Score | 5,800 | 5,800 |
| Generation | A-Series | Phenom II |
| Socket | FM2+ | AM3 |
| Release Year | 2016 | 2010 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Radeon RX 570 | Radeon RX 570 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | A10-7890K |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | A10-7890K (the lower model is often sufficient) |
Their scores are nearly identical (A10-7890K: 5800 points / Phenom II X6 1055T: 5800 points). Choose the less expensive option or the one that fits your current motherboard.
A10-7890K is A-Series, while Phenom II X6 1055T is Phenom II.The sockets differ (FM2+ / AM3), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 570 pairs well with A10-7890K and Radeon RX 570 pairs well with Phenom II X6 1055T. If either GPU is too strong or too weak, one part holds the other back.
