In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270X Crossfire are significantly better than the AMD Radeon R9 270 DirectCU II OC Edition.

The R9 270X has a 50 MHz higher core clock speed and 80 more Texture Mapping Units than the R9 270. This results in the R9 270X providing 84 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R9 270X has a 50 MHz higher core clock speed and 32 more Render Output Units than the R9 270. This results in the R9 270X providing 33.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 270 was released less than a year after the R9 270X, 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 R9 270, 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 179.2 GB/sec greater memory bandwidth than the R9 270, which means that the memory performance of the R9 270X is massively better than the R9 270.

The Radeon R9 270X Crossfire has 2560 Shader Processing Units and the Radeon R9 270 DirectCU II OC Edition has 1280. However, the actual shader performance of the R9 270X is 2285 and the actual shader performance of the R9 270 is 1061. The R9 270X having 1224 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 R9 270.

The Radeon R9 270X Crossfire requires 360 Watts to run and the Radeon R9 270 DirectCU II OC Edition requires 175 Watts. We would recommend a PSU with at least 750 Watts for the R9 270X. The R9 270X requires 185 Watts more than the R9 270 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 R9 270.

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.
Radeon R9 270 DirectCU II OC Edition is a special edition of the fast-middle-class Radeon R9 270.
This edition comes with a custom cooling system called "DirectCU II", which reduces the card's temperature under load, significantly and comes overclocked out of the box in the central unit that was increased from 925MHz to 950MHz, while the Boost clock is now of 975MHz.
Benchmarks indicate a 3% performance boost over the standard edition.
