Still, the non-synthetic GPU-related tests (gaming, OpenCL) shows little difference between A10-7800 & A8-7600. In most cases it falls within 10% and NEVER reaches theoretical 25% - even 20.
I agree with gadgety - the REAL sweet spot is A8-7600. In all test I could found, it shows 90%+ performance of A10-7800 - I mean GPU tests, no mention to CPU. So the ridiculous cost of A10-7800 just has no sense.
