The standalone Aliens vs. Predator benchmark uses DX11 features such as hardware tessellation and advanced shadow sampling to draw and animate everyone's favourite xenomorph.
Average framerate
GeForce GTX 680 is given a good spanking by the pair of Radeons in Aliens vs. Predator.
Per-second framerate
Zooming into the per-second framerate results shows near-identical performance by the two pre-overclocked GTX 680s; the Classified's line obscures the Gigabyte's. Go back to the first graph and the average framerate similarity comes as no surprise.
Per-frame performance
We can also examine the per-frame performance and then determine just how quickly these three graphics cards spit them out. The premise is to have the GPUs render as many frames as possible in the least amount of time. Frames that take longer than 33ms (or an equivalent 30fps) are noticeable, especially if bunched-up together. Ideally, you want sub-20ms frames (50fps) to be a high proportion of total frames.
But the EVGA is better at knocking out a larger percentage of sub-33ms frames. According to our calculations, it manages to meet this standard in one-quarter of total frames, compared with one-fifth for the Gigabyte. Is this evidence of the larger framebuffer coming into play? Probably not, because looking at the memory-usage logs from Afterburner the game uses no more than 1,699MB of video memory.
