This game's engine favors AMD GPUs, which explains the triumph of the two Radeons. It is only with enabled antialiasing that we see a difference between the GTX 780 Ti cards from Zotac and Nvidia, but it's small.
This game shows us typical standings for today’s test session:
The Zotac is 6 to 9% ahead of the reference GeForce GTX 780 Ti, which is also outperformed by the well-overclocked EVGA GeForce GTX 780 Superclocked.
Tomb Raider (2013)
The Zotac GeForce GTX 780 Ti AMP! Edition enjoys the same advantage over the reference card as in the previous game.
The increased clock rates of the Zotac GeForce GTX 780 Ti AMP! Edition don’t solve the problem of low bottom speed in this game, which plagues every Nvidia-based card. Otherwise, we have the same picture as in most of the previous tests.
Metro: Last Light
Here are the results with the Advanced PhysX technology turned on:
The Zotac GeForce GTX 780 Ti AMP! Edition is 7-8% ahead of the reference GeForce GTX 780 Ti and twice as fast as the AMD Radeon R9 290X. The overclocked GTX 780 from EVGA is very close to the GTX 780 Ti here.
We’ve got a different picture with the Advanced PhysX option turned off:
The AMD-based graphics cards perform better now, but the standings of the three GeForce GTX cards haven’t changed.
