First, let's see how faster the Zotac GeForce GTX 780 Ti AMP! Edition (1006/1027/7200 MHz) is in comparison with the reference Nvidia GeForce GTX 780 Ti (876/928/7000 MHz):
The Zotac is an average 7% faster than the reference card across all of our tests. The maximum advantage can be observed in Total War: Rome II and Batman: Arkham Origins. The gap is the narrowest in the lower-quality mode of GRID 2, Company of Heroes 2 and Hitman: Absolution.
In the next pair of our summary charts we compare the Zotac GeForce GTX 780 Ti AMP! Edition and the EVGA GeForce GTX 780 Superclocked (at 1032/1085/7348 MHz):
Despite the impressive overclocking potential of the original card from EVGA, the Zotac GeForce GTX 780 Ti AMP! Edition is ahead at its default clock rates in most of the tests, enjoying an average advantage of 6-8%.
We guess these two pairs of diagrams are enough considering that we've tested the rest of the cards a number of times in our earlier reviews.
We measured the power consumption of computer systems with different graphics cards using a multifunctional panel Zalman ZM-MFC3 which can report how much power a computer (the monitor not included) draws from a wall socket. There were two test modes: 2D (editing documents in Microsoft Word and web surfing) and 3D (the intro scene of the Swamp level from Crysis 3 running four times in a loop at 2560x1440 with maximum visual quality settings but without MSAA). Here are the results:
As we can see, these configurations are comparable in terms of their power draw. The gap between the most economical and the most voracious system is only 41 watts, which is negligible for computers of that class. As expected, the configuration with Zotac GeForce GTX 780 Ti AMP! Edition has the highest power draw, up to 570 watts at peak loads, which is 41 watts higher than the configuration with reference GTX 780 Ti needs.
We can also add that each of the tested configurations can be powered by a 600W PSU.
The Zotac GeForce GTX 780 Ti AMP! Edition is just the first in our series of reviews of original GK110-based graphics cards, yet we already recommend it to every gamer who wants high performance whatever the cost. This graphics card is pre-overclocked and also has additional GPU overclocking potential. Its Zotac Triple Silencer cooler is more efficient and quieter than the reference card’s. Although not exactly silent, it will satisfy the majority of users in terms of noisiness, too. We guess the noise level, which is average, is in fact the only imperfection in this otherwise excellent product.
But if you don’t like it for some reason, you may want to wait for our next GeForce GTX 780 Ti review!
