In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 250 1GB Crossfire are noticeably better than the AMD Radeon HD 6850 Sapphire 1GB Edition.

The R7 250 has a 225 MHz higher core clock speed and the same number of Texture Mapping Units as the HD 6850. This results in the R7 250 providing 10.8 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 R7 250 has a 225 MHz higher core clock speed than the HD 6850, but the HD 6850 has 16 more Render Output Units than the R7 250. As a result, the HD 6850 exhibits a 8.8 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 6850, 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 6850 when running the latest games.

The R7 250 has 1024 MB more video memory than the HD 6850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R7 250 also has superior memory performance overall.

The R7 250 has 19.2 GB/sec greater memory bandwidth than the HD 6850, which means that the memory performance of the R7 250 is slightly better than the HD 6850.

The Radeon R7 250 1GB Crossfire has 768 Shader Processing Units and the Radeon HD 6850 Sapphire 1GB Edition has 960. However, the actual shader performance of the R7 250 is 685 and the actual shader performance of the HD 6850 is 372. The R7 250 having 313 better shader performance and an altogether better performance when taking into account other relevant data means that the R7 250 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 6850.

The R7 250 transistor size technology is 12 nm (nanometers) smaller than the HD 6850. This means that the R7 250 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6850.

The Radeon R7 250 1GB Crossfire requires 130 Watts to run but there is no entry for the Radeon HD 6850 Sapphire 1GB Edition. We would recommend a PSU with at least 500 Watts for the R7 250 and a PSU with at least 500 Watts for the HD 6850. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewOverview
Radeon R7 250 1GB Crossfire is a solution of two Radeon R7 250 1GB put together using AMD's Crossfire Technology.

It consists of 2 GPUs Codenamed GCN 1.1 Oland XT which, together, offer 768 Shader Processing Units, 48 TMUs and 16 ROPs.

The central unit runs at 1000MHz and goes up to 1050MHz, in Turbo Mode.

Each GPU accesses a 1GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1125MHz.

Power Consumption
Power Consumption lies between 125W and 135W.

Radeon R7 250 1GB Crossfire Offers slightly more Performance than the Higher Positioned Radeon R7 260 but comes at a higher cost and relies highly in proper Driver Support..

System Suggestions
Radeon R7 250 1GB Crossfire is best suited for resolutions up to and including 1920x1080. We recommend a Performance Processor and 8GB of RAM for Optimal Performance.
Radeon HD 6850 Sapphire 1GB Edition is a special edition of the Radeon HD 6850. See the page of the standard edition for more information about it.
There are no new features that affect Radeon HD 6850 Sapphire 1GB Edition's gaming performance directly and so its performance is exactly like the one the standard Radeon HD 6850 delivers.
