Overclocking
GPU-Z loses the plot a little. We can say the card ran at 1,812MHz core (boosting to 2,040MHz) and 2,242MHz memory. That's enough to add another 10 per cent or so performance.
Even so, going by previous results, a seat-of-your-pants GTX 1070 Ti is barely a match for the stock GTX 1080. We mention this because said GPU has a very small price premium over this EVGA model, thus putting value-for-money into serious question.
