bro ASIC is basically tells about the Chip's or silicon's overall performance regarding HEating and speed comparing to same model. like we can compare 280x vs other 280x on the basis of ASIC quality. Every cards performance varies to each other. in the same Model some card perform good some below optimal.
Your GPUs ASIC Quality Suggest:
LOW Voltage leakage: so you will need More Voltages for overclocking
More Power Consumption: high voltages will increases the power consumption
More HEat Generation: high voltage generate more HEAt
High Temperatures: More HEat raises the temperatures
But you cannot say it is Perfect Link that reflect you chip,. because sometimes GPU perform way better or different from mentioned characteristics. but it is true on most of the cases. atleast i experienced similar. you ASIC Quality definitely lower, but its a luck of a draw. difference would be max 2-5 fps. not more than that. sometimes it wont be any.
For example: My Sapphire 7950 at 54% was scoring lower to MSI 7950 @60% clock to clock (same clocks and settings). this is what i experienced.
NVIDIA GPUs are mostly above 70% due to efficient built. but AMD usually 50-65% which suggest high power draw but great for overclocking.
