Benchmarks Real world tests of Radeon R7 250 vs HD 7770

Passmark Industry standard benchmark for overall graphics card performance

We don't use 3DMark to draw GPU performance conclusions but it does make for a great optimization target.

3DMark 11 Graphics Industry standard benchmark that tests DirectX 11 GPU performance

It’s not clear whether this is the same GPU as in 290X or not, and in lieu of specs AMD has given us a single benchmark: 3DMark Firemark, where it scores better than 6800.

3DMark Vantage Graphics Industry standard benchmark that tests DirectX 10 GPU performance

We'll turn to 3DMark Vantage first to stress ROP and texel rates.

BioShock Infinite 1920 x 1080 - Ultra preset + DX11 (DDOF)

Radeon R7 250
20.3 fps
Radeon HD 7770
24.7 fps
The performance results show that dual graphics does make the Kaveri APU run games at 1080P such as Bioshock Infinite and Tomb Raider which otherwise isn’t possible (atleast on high settings configuration) but that means users would have to spend $59 – $89 more on these graphics cards for a little performance upgrade and even that in a few titles since AMD CrossFire isn’t great on all gaming titles.

Crysis 3 1920 x 1080 - Very High preset + 16xAF + 2xSMAA

Radeon R7 250
10.6 fps
Radeon HD 7770
12.6 fps
We can look at an individual game, like Crysis 2, and see that the Nvidia card is a good 20 percent faster.
