Sorry to break it down for you, but on AMD cards, higher ASIC Quality equals higher leakage current, which equals higher power draw and higher temperatures. The Stilt, famous AMD overclocker, posted about this on the Finnish tech site Muropaketti a couple of days ago. I'll find that post again and translate it for you guys if you'll just give me a moment! Google translate doesn't do a very good job with Finnish, so here goes (original post here)
"On AMD, ASIC Quality stands for the leakage current value (SIDD).
A larger static leakage current = lower operating voltage, better scalability with voltage, a steeper power draw scaling with voltage, lower maximum voltage, higher temperature and higher power requirement.
ASICs with high leakage current have a lower efficiency, because power phase efficiency drops when the current increases even if the performance would stay the same. Similarly, higher currents result in higher power delivery losses in the components between the GPU and the VRM power phase. The chip itself also runs hotter due larger and more frequently appearing hotspots."
He sums it up in the end: "Unless you are planning on using extreme cooling, a lower ASIC Quality is always preferable."

Nije li ASIC score na AMD-ovim, što niži to bolji?
