In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 3-way Crossfire are massively better than the AMD Radeon R7 250 v2 MSI OC 2GB + Radeon R7 7870K Dual.

The R7 250 has a 250 MHz higher core clock speed than the HD 7950, but the HD 7950 has 280 more Texture Mapping Units than the R7 250. As a result, the HD 7950 exhibits a 210 GTexel/s better Texture Fill Rate than the R7 250. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R7 250 has a 250 MHz higher core clock speed than the HD 7950, but the HD 7950 has 80 more Render Output Units than the R7 250. As a result, the HD 7950 exhibits a 60 GPixel/s better Pixel Fill Rate than the R7 250. 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 three years more recently than the HD 7950, and so the R7 250 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 7950 when running the latest games.

The HD 7950 has 6144 MB more video memory than the R7 250, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7950 also has superior memory performance overall.

The HD 7950 has 662.4 GB/sec greater memory bandwidth than the R7 250, which means that the memory performance of the HD 7950 is massively better than the R7 250.

The Radeon HD 7950 3-way Crossfire has 5376 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 7950 is 3656 and the actual shader performance of the R7 250 is 838. The HD 7950 having 2818 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7950 delivers a massively smoother and more efficient experience when processing graphical data than the R7 250.

The Radeon HD 7950 3-way Crossfire requires 540 Watts to run and the Radeon R7 250 v2 MSI OC 2GB + Radeon R7 7870K Dual requires 150 Watts. 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 7950. The HD 7950 requires 390 Watts more than the R7 250 to run. The difference is significant enough that the HD 7950 may have an adverse affect on your yearly electricity bills in comparison to the R7 250.

GPU Mini Review

Mini ReviewRadeon HD 7950 3-way Crossfire is a solution of three Radeon HD 7950 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 7950 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 somewhat superior to a single Radeon HD 7990 performing by itself it might be worse (depending on whether or not the 3D game supports crossfire or in the graphics driver) than a single Radeon HD 7950. Expect this combination to draw up to 540 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
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.
