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 250 Diamond 1GB Edition.

The GTX 980 has a 126 MHz higher core clock speed and 232 more Texture Mapping Units than the R7 250. This results in the GTX 980 providing 264.3 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 126 MHz higher core clock speed and 120 more Render Output Units than the R7 250. This results in the GTX 980 providing 136.1 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 250, 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 250, 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 375.2 GB/sec greater memory bandwidth than the R7 250, which means that the memory performance of the GTX 980 is massively better than the R7 250.

The Radeon R7 250 Diamond 1GB Edition has 384 Shader Processing Units and the GeForce GTX 980 4GB SLI has 4096. However, the actual shader performance of the R7 250 is 343 and the actual shader performance of the GTX 980 is 6724. The GTX 980 having 6381 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 250.

The Radeon R7 250 Diamond 1GB Edition requires 65 Watts to run and the GeForce GTX 980 4GB SLI requires 350 Watts. We would recommend a PSU with at least 400 Watts for the R7 250 and a PSU with at least 750 Watts for the GTX 980. The GTX 980 requires 285 Watts more than the R7 250 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 250.

GPU Mini Review

Mini ReviewOverview
Radeon R7 250 Diamond 1GB Edition is a special edition of AMD's fast-middle-class Radeon R7 250 1GB, created by Diamond MultiMedia.

Overclock Out of The Box
The Clock Frequencies of both Central Unit and Operating Memory Clock Remain the Same.

Cooling Solution
The Cooling System remains the same.

Performance
Without Overclocking Out of The Box, Radeon R7 250 Diamond 1GB Edition is as fast as the reference Radeon R7 250 1GB.
Overview
GeForce GTX 980 4GB SLI is a solution of two GeForce GTX 980 4GB put together using NVIDIA's SLI technology.

Architecture
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.

GPU
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.

Performance
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.
