Overclocking and Overclocked Performance
By default, the GPU already utilizes an impressive overclock, which curbs the amount of headroom via manual boosts. For example, the power limit is restricted to 106 percent and means it’s quite difficult to obtain large gains from the stock overclock. Despite this, I managed to increase the core clock by 70MHz to 1273MHz which boosted under load to 1512MHz. The memory overclocked to an effective rate of 7632MHz which is acceptable but some way off an 8000MHz+ overclock seen on some models. However, this shouldn’t really make a substantial difference in performance.

Once overclocked, the GPU fares superbly and records impressive numbers which really rivals other high-end GTX 980Ti solutions.
Rather surprisingly, there’s a noticeable deficit compared to the 1080P results suggesting the lower core clock really comes into play at higher resolutions.
During 4K testing, the gap is less pronounced, and there’s little to choose from different variants of the GTX 980Ti.
