In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7770 Crossfire are significantly better than the AMD Radeon R7 260X v2 PowerColor OC 1GB Edition.

The R7 260X has a 30 MHz higher core clock speed than the HD 7770, but the HD 7770 has 24 more Texture Mapping Units than the R7 260X. As a result, the HD 7770 exhibits a 22.3 GTexel/s better Texture Fill Rate than the R7 260X. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R7 260X has a 30 MHz higher core clock speed than the HD 7770, but the HD 7770 has 16 more Render Output Units than the R7 260X. As a result, the HD 7770 exhibits a 15.5 GPixel/s better Pixel Fill Rate than the R7 260X. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R7 260X was released over a year more recently than the HD 7770, and so the R7 260X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7770.

The HD 7770 has 1024 MB more video memory than the R7 260X, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7770 also has superior memory performance overall.

The HD 7770 has 48 GB/sec greater memory bandwidth than the R7 260X, which means that the memory performance of the HD 7770 is noticeably better than the R7 260X.

The Radeon R7 260X v2 PowerColor OC 1GB Edition has 896 Shader Processing Units and the Radeon HD 7770 Crossfire has 1280. However, the actual shader performance of the R7 260X is 784 and the actual shader performance of the HD 7770 is 1088. The HD 7770 having 304 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7770 delivers a significantly smoother and more efficient experience when processing graphical data than the R7 260X.

The Radeon R7 260X v2 PowerColor OC 1GB Edition requires 105 Watts to run and the Radeon HD 7770 Crossfire requires 160 Watts. We would recommend a PSU with at least 500 Watts for the R7 260X and a PSU with at least 600 Watts for the HD 7770. The HD 7770 requires 55 Watts more than the R7 260X to run. The difference is significant enough that the HD 7770 may have an adverse affect on your yearly electricity bills in comparison to the R7 260X.

Performance
Benchmarks Indicate a 1% Performance Boost over the Reference Radeon R7 260X v2.
Radeon HD 7770 Crossfire is a solution of two Radeon HD 7770 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 7770 to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up around 55% better a single Radeon HD 7770 performing by itself but at times (depending whether or not the 3D game supports crossfire or in the graphics driver) it performed worse than a single Radeon HD 7770. Expect this combination to draw up to 160 Watt though the average power consumption should be slightly lower.
Most demanding games will run at the highest settings.
