In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 5850 Crossfire are very slightly better than the AMD Radeon HD 7870 DirectCU II 2GB Edition.

The HD 7870 has a 160 MHz higher core clock speed than the HD 5850, but the HD 5850 has 64 more Texture Mapping Units than the HD 7870. As a result, the HD 5850 exhibits a 41.6 GTexel/s better Texture Fill Rate than the HD 7870. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7870 has a 160 MHz higher core clock speed than the HD 5850, but the HD 5850 has 32 more Render Output Units than the HD 7870. As a result, the HD 5850 exhibits a 22.1 GPixel/s better Pixel Fill Rate than the HD 7870. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7870 was released over a year more recently than the HD 5850, and so the HD 7870 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 5850.

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 Radeon HD 5850 Crossfire and the Radeon HD 7870 DirectCU II 2GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 5850 has 101.1 GB/sec greater memory bandwidth than the HD 7870, which means that the memory performance of the HD 5850 is massively better than the HD 7870.

The Radeon HD 5850 Crossfire has 2880 Shader Processing Units and the Radeon HD 7870 DirectCU II 2GB Edition has 1280. However, the actual shader performance of the HD 5850 is 1591 and the actual shader performance of the HD 7870 is 1099. The HD 5850 having 492 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 5850 delivers a massively smoother and more efficient experience when processing graphical data than the HD 7870.

The HD 7870 transistor size technology is 12 nm (nanometers) smaller than the HD 5850. This means that the HD 7870 is expected to run slightly cooler and achieve higher clock frequencies than the HD 5850.

The Radeon HD 5850 Crossfire requires 300 Watts to run but there is no entry for the Radeon HD 7870 DirectCU II 2GB Edition. We would recommend a PSU with at least 600 Watts for the HD 5850.

GPU Mini Review

Mini ReviewRadeon HD 5850 Crossfire is a solution of two Radeon HD 5850 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 5850 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, up to 60% better than a single Radeon HD 5850 performing by itself but it might be worse (depending on whether or not the 3D game supports crossfire or in the graphics driver) than a single Radeon HD 5850. Expect this combination to draw up to 302 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
Radeon HD 7870 DirectCU II 2GB Edition is a special edition of the powerful Radeon HD 7870. See the standard version for more information about it.
The new features include the DirectCU II cooling solution which is 20% more effective than the reference cooler, according to Asus and a small increase in the core-clock to 1010MHz as well as in the memory clock to 1210MHz.
Benchmarks indicate almost no performance boost when compared to the standard Radeon HD 7870 and so its performance is on level with the it as the boost is beneath 1%.
All games, including demanding one's, will run on the highest settings.
