Benchmarks Real world tests of Radeon HD 7870 vs 7770

Passmark Industry standard benchmark for overall graphics card performance

3DMark 11, as the name might probably suggest, makes use of the Microsoft DirectX 11 API and puts every feature of it to use, creating astonishingly realistic visuals.

3DMark Vantage (Texture Fill) Industry standard benchmark that tests DirectX performance

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

Crysis: Warhead (2013) 1920x1080 - Enthusiast Quality + 4xAA

Radeon HD 7870
44.2 fps
Radeon HD 7870 Radeon HD 7770 @ anandtech.com
Since Crysis 2 is a multi-platform game with major development focus on the console, the graphics on launch day were only DirectX 9.

Batman: Arkham City 1920x1200 - Extreme quality + FXAA-HIGH

Radeon HD 7870 Radeon HD 7770 @ anandtech.com
Batman: Arkham City uses the same Unreal Engine by Epic as Batman: Arkham Asylum, but it has, thanks to the engine's modularity, been overhauled and equipped with the latest technologies, including a graphics engine that takes advantage of DirectX 11.

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

Radeon HD 7870
25.8 fps
Radeon HD 7770
12.6 fps
We chose Crysis 2 as a standard test representing typical 3D gaming usage, because it offers the following: very high power draw; high repeatability; is a current game that is supported on all cards because of its DirectX 9 roots; drivers are actively tested and optimized for it; supports all multi-GPU configurations; test runs in a relatively short time and renders a non-static scene with variable complexity.

The HD 7870 is a very efficient design, so the jokerCard with its Tahiti processor doesn't do well.
