Notes

To illustrate the performance differential between the A10-7800's two configurable TDPs, the chip has been benchmarked with the latest available AMD Catalyst driver (14.7 beta) in both the 65W and 45W modes. Benchmark performance at 65W should be just shy of the range-topping A10-7850K and, keeping an eye on both sides of the fence, the nearest Intel competitors in our line-up are the Core i3-4330 (£90) and the Core i5-4440 (£130).

Readers should note that due to unforeseen circumstances we've had to change the motherboard on our AMD FM2+ test platform to the previously-reviewed Gigabyte G1.Sniper A88X. The impact on performance benchmarks should be negligible, though power consumption may be a tad higher on this larger ATX board.
