In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 4GB SLI are massively better than the AMD Radeon R7 250X Sapphire Vapor-X OC Edition.

The GTX 980 has a 26 MHz higher core clock speed and 216 more Texture Mapping Units than the R7 250X. This results in the GTX 980 providing 244.3 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 GTX 980 has a 26 MHz higher core clock speed and 112 more Render Output Units than the R7 250X. This results in the GTX 980 providing 126.5 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 GTX 980 was released less than a year after the R7 250X, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 980 has 7168 MB more video memory than the R7 250X, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 980 also has superior memory performance overall.

The GTX 980 has 365.6 GB/sec greater memory bandwidth than the R7 250X, which means that the memory performance of the GTX 980 is massively better than the R7 250X.

The GeForce GTX 980 4GB SLI has 4096 Shader Processing Units and the Radeon R7 250X Sapphire Vapor-X OC Edition has 640. However, the actual shader performance of the GTX 980 is 6724 and the actual shader performance of the R7 250X is 598. The GTX 980 having 6126 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 980 delivers a massively smoother and more efficient experience when processing graphical data than the R7 250X.

The GeForce GTX 980 4GB SLI requires 350 Watts to run and the Radeon R7 250X Sapphire Vapor-X OC Edition requires 80 Watts. We would recommend a PSU with at least 750 Watts for the GTX 980 and a PSU with at least 450 Watts for the R7 250X. The GTX 980 requires 270 Watts more than the R7 250X to run. The difference is significant enough that the GTX 980 may have an adverse affect on your yearly electricity bills in comparison to the R7 250X.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 980 4GB SLI is a solution of two GeForce GTX 980 4GB put together using NVIDIA's SLI technology.

The Second variant of the Maxwell Architecture, despite being also manufactured with a 28nm technology, has an extremely large L2 Cache and features a Third Generation Delta Color Compression which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.

It consists of 2 GPUs codenamed GM204-400-A1 which, together, offer 4096 Shader Processing Units, 256 TMUs and 128 ROPs, on a 512-bit memory interface of fast GDDR5. The central unit runs at 1126MHz and goes up to 1216MHz, in Turbo Mode, while the memory clock operates at 1753MHz.

Power Consumption
Power Consumption lies between 300W and 400W.

Gaming benchmarks prove that at 4K (3840x2160) GeForce GTX 980 4GB SLI is over 7% faster than AMD's Radeon R9 295X2.

System Suggestions
We recommend a very strong processor (Intel Core i7 Six Core/AMD FX Eight Core) and 16GB of RAM for a system with GeForce GTX 980 4GB SLI.
Radeon R7 250X Sapphire Vapor-X OC Edition is a special edition of the fast-middle-class Radeon R7 250X.
This edition comes with a custom cooling solution which will make the card even cooler and overclocked out of the box in the central unit which was increased from 950MHz to 1100MHz, while the operating memory clock is now of 1300MHz, instead of 1125MHz.
Benchmarks indicate a 10% performance boost when compared to the reference R7 250X.
