In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270X Crossfire are noticeably better than the Nvidia GeForce GTX 770.

The GeForce GTX 770 has a 46 MHz higher core clock speed than the R9 270X, but the R9 270X has 32 more Texture Mapping Units than the GeForce GTX 770. As a result, the R9 270X exhibits a 26.1 GTexel/s better Texture Fill Rate than the GeForce GTX 770. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GTX 770 has a 46 MHz higher core clock speed than the R9 270X, but the R9 270X has 32 more Render Output Units than the GeForce GTX 770. As a result, the R9 270X exhibits a 30.5 GPixel/s better Pixel Fill Rate than the GeForce GTX 770. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 270X was released less than a year after the GeForce GTX 770, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The R9 270X has 2048 MB more video memory than the GeForce GTX 770, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 270X also has superior memory performance overall.

The R9 270X has 134.1 GB/sec greater memory bandwidth than the GeForce GTX 770, which means that the memory performance of the R9 270X is massively better than the GeForce GTX 770.

The Radeon R9 270X Crossfire has 2560 Shader Processing Units and the GeForce GTX 770 has 1536. However, the actual shader performance of the R9 270X is 2285 and the actual shader performance of the GeForce GTX 770 is 1667. The R9 270X having 618 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 270X delivers a massively smoother and more efficient experience when processing graphical data than the GeForce GTX 770.

The Radeon R9 270X Crossfire requires 360 Watts to run and the GeForce GTX 770 requires 230 Watts. We would recommend a PSU with at least 750 Watts for the R9 270X and a PSU with at least 550 Watts for the GeForce GTX 770. The R9 270X requires 130 Watts more than the GeForce GTX 770 to run. The difference is significant enough that the R9 270X may have an adverse affect on your yearly electricity bills in comparison to the GeForce GTX 770.

GPU Mini Review

Mini ReviewRadeon R9 270X Crossfire is a solution of two Radeon R9 270X put together using AMD'S Crossfire technology.
Check the page of Radeon R9 270X 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 to x% better than a single Radeon R9 270X 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 R9 270X. Expect this combination to draw up to 360 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
