After having had a look at 11 different GeForce GTX 980 Ti reference graphics cards we’ve gathered quite a few interesting results. The lowest ASIC value we measured was 56.4% and the highest was 80.2%. In our opinion the spread is huge and we were suprised this fact. The difference is a whopping 23.8% and things become especially worrying looking at the corresponding clock speeds. The card which had an ASIC quality of 56.4% had a maximum boost clock of 1139 MHz, whereas the 80.2% card ran at 1240MHz.
In the end we believe there are two really interesting facts, which can be extracted from these tests. First of all there is the fact, that vendors sell one and the same graphics but the clock speeds vary by up to 100MHz or even more. Therefore, depending on luck, you can end up with a graphics card which is almost 8.9% faster, then another one, which is supposed to be the very same card. Apart from that it is interesting to see that there is a linear dependency between ASIC quality and boost clock speed – which we actually measured using GPU-Z and 3DMark Firestrike.
