In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7770 Vapor-X GHz OC Edition are very slightly better than the AMD Radeon R7 250 v2 MSI OC 2GB + Radeon R7 7870K Dual.

The HD 7770 has a 50 MHz higher core clock speed than the R7 250, but the R7 250 has 16 more Texture Mapping Units than the HD 7770. As a result, the R7 250 exhibits a 14.8 GTexel/s better Texture Fill Rate than the HD 7770. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7770 has a 50 MHz higher core clock speed than the R7 250 and the same number of Render Output Units. This results in the HD 7770 providing 0.8 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 R7 250 was released over a year more recently than the HD 7770, and so the R7 250 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 R7 250 has 2048 MB more video memory than the HD 7770, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the HD 7770 has superior memory performance.

The HD 7770 has 25.6 GB/sec greater memory bandwidth than the R7 250, which means that the memory performance of the HD 7770 is slightly better than the R7 250.

The Radeon HD 7770 Vapor-X GHz OC Edition has 640 Shader Processing Units and the Radeon R7 250 v2 MSI OC 2GB + Radeon R7 7870K Dual has 896. However, the actual shader performance of the HD 7770 is 598 and the actual shader performance of the R7 250 is 838. The R7 250 having 240 better shader performance is not particularly notable, as altogether the HD 7770 performs better when taking into account other relevant data.

The Radeon R7 250 v2 MSI OC 2GB + Radeon R7 7870K Dual requires 150 Watts to run but there is no entry for the HD 7770. We would recommend a PSU with at least 400 Watts for the R7 250, but we do not have a recommended PSU wattage for the HD 7770.

GPU Mini Review

Mini ReviewRadeon HD 7770 Vapor-X GHz OC Edition is a special edition of the fast-middle-class Radeon HD 7770. See the standard version for more information about it.
The differences include increased memory and core clocks, from 1125MHz to 1300MHz and from 1000MHz to 1100MHz, respectively. A new quiet and efficient cooling system, called Vapor-X, is also available.
Benchmarks indicate a 8% performance boost when compared to the standard Radeon HD 7770.
Benchmarks indicate that the most demanding games (e.g. Metro 2033) still require reduced settings to be played smoothly.
Radeon R7 250 v2 MSI OC 2GB + Radeon R7 7870K Dual is a Solution of one Dedicated Radeon R7 250 v2 MSI OC 2GB Edition and one Integrated Radeon R7 7870K Dual put together using AMD's Asymmetric Crossfire Technology.

Architecture & Other Relevant Data
For more information about the Architecture and Other Relevant Data, please refer to the Pages of [Radeon R7 250 v2 MSI OC 2GB Edition](http://www.game-debate.com/hardware/index.php?gid=2420&graphics=Radeon%20R7%20250%20v2%20MSI%20OC%202GB%20Edition) and [Radeon R7 7870K](http://www.game-debate.com/hardware/index.php?gid=3000&graphics=Radeon%20R7%207870K).

Just like Crossfire, Asymmetric Crossfire can lead to Micro Stuttering.
Furthermore, Performance relies heavily on Driver Support, whereas it can lead to an enormous Performance Boost over each Graphics Card Operating Alone or to a Performance Decrease in which it is best to disable the Asymmetric Crossfire. Overall, Expect Performance Similar to Radeon R7 250X.

System Suggestions
Radeon R7 250 v2 MSI OC 2GB + Radeon R7 7870K Dual is best suited for resolutions up to and including 1600x900. We Recommend 8GB of RAM for Optimal Performance.
