Using EVGA’s PrecisionX
Before we get to the performance charts, let’s see how we equalized the GTX 770 2GB reference version and the EVGA 770 SC 4GB version clocks for identical performance. We used the EVGA tool, PrecisionX, to set the clockspeeds of each card to equalize performance.
Here are the specifications for the reference GTX 770: The reference GTX 770 is clocked at 1046MHz with a guaranteed Boost to 1085MHz. In the case of our own reference GTX 770, it boosts to 1136MHz with the Power and Temperature sliders maxed out. In the case of the EVGA card, it is clocked at 1111MHz or +65MHz higher than the reference GTX 770.
However, things are still not equal as the EVGA card will boost to 1162MHz. So we downclocked the EVGA card to 1046MHz base clock, and overclocked the reference version +26MHz so the boosts were identical at 1162MHz. Since our cards never throttled, the performance became effectively identical between the two cards with the amount of vRAM being the only potentially differentiating factor.
Let’s head to the performance charts to see how the now performance-equalized EVGA GTX 770 SC 4GB card compares with the reference GTX 770 2GB card when we attempt to stress the framebuffers with maximum settings, high AA, and super-widescreen resolutions.
