Benchmarks: Core Performance
The A10-7800's maximum core speed is limited to 3.9GHz, putting the chip just behind the 4.0GHz A10-7850K in the single-threaded PiFast benchmark. No surprises there, though already we're seeing the impact of the 45W configurable TDP - choose to run in the more efficient mode and the chip isn't able to maintain top speed, resulting in a slight dip in performance. There's not a great deal in it, and more to the point, Intel's single-threaded supremacy remains clear to see.
Putting all cores to work in the multi-threaded Cinebench test sees the A10-7800 slot in right where we'd expect it to be. Interestingly, performance drops by 12 per cent in this scenario when switching to the 45W TDP. In the optimised mode, the chip is aggressively limiting frequency, resulting in CPU core performance being on par with the 45W A8-7600.
Optimised, multi-threaded workloads are believed to be a sign of the future, and it's in these scenarios that AMD's architecture is strong. The 65W A10-7800 is almost a match for the 95W A10-7850K.
