First of all, let’s see what benefits the GeForce GTX 770 provides in comparison with the GeForce GTX 680, both working at their default clock rates.
The new card is an average 9-11% faster than its predecessor. Considering the more attractive price, the GeForce GTX 770 is undoubtedly a success.
On the other hand, we have to disappoint prospective GeForce GTX 770 users a little. Their graphics card is going to be 14 to 27% slower than the GeForce GTX 780. The gap is especially large if you enable antialiasing.
You can’t expect to bridge the gap by means of overclocking because the GeForce GTX 770 still loses to the standard GeForce GTX 780 even if clocked at 1180/1220/7872 MHz.
The gap is now 6 to 19%, depending on the resolution and quality settings. The GeForce GTX 780 enjoys the largest advantage when antialiasing is turned on.
Now here is the competition between the GeForce GTX 770 and the Radeon HD 7970 GHz Edition at their default clock rates:
Although the GeForce GTX 770 is faster than the GeForce GTX 680, the AMD-based card is still superior in such games as Metro 2033: The Last Refuge, Sleeping Dogs, Hitman: Absolution, Tomb Raider (2013), GRID 2 and in the beta version of Company of Heroes 2. The GeForce GTX 770, in its turn, wins in Total War: SHOGUN 2 – Fall of the Samurai, Sniper Elite V2, Crysis 3 (at 1920?1080), BioShock Infinite (with antialiasing) and Metro: Last Light. Overall, the GeForce GTX 770 is an average 3% faster than the Radeon HD 7970 GHz Edition across all the tests.
