In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 4GB SLI are massively better than the AMD Radeon HD 4850x2.

The GTX 980 has a 501 MHz higher core clock speed and 216 more Texture Mapping Units than the Radeon HD 4850x2. This results in the GTX 980 providing 263.3 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 501 MHz higher core clock speed and 112 more Render Output Units than the Radeon HD 4850x2. This results in the GTX 980 providing 134.1 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 over three years more recently than the Radeon HD 4850x2, and so the GTX 980 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon HD 4850x2 when running the latest games.

The GTX 980 has 6144 MB more video memory than the Radeon HD 4850x2, 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 385.2 GB/sec greater memory bandwidth than the Radeon HD 4850x2, which means that the memory performance of the GTX 980 is massively better than the Radeon HD 4850x2.

The GeForce GTX 980 4GB SLI has 4096 Shader Processing Units and the Radeon HD 4850x2 has 1600. However, the actual shader performance of the GTX 980 is 6724 and the actual shader performance of the Radeon HD 4850x2 is 700. The GTX 980 having 6024 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 Radeon HD 4850x2.

The GTX 980 transistor size technology is 27 nm (nanometers) smaller than the Radeon HD 4850x2. This means that the GTX 980 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 4850x2.

The GeForce GTX 980 4GB SLI requires 350 Watts to run and the Radeon HD 4850x2 requires 250 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 Radeon HD 4850x2. The GTX 980 requires 100 Watts more than the Radeon HD 4850x2 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 Radeon HD 4850x2.

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.

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.
The Radeon R700 is the engineering codename for a graphics processing unit series released by AMD Graphics Product Group, sold under the ATI brand. The foundation chip, codenamed RV770, was announced and demonstrated on June 16, 2008 as part of the FireStream 9250 and Cinema 2.0 initiative launch media event, with official release of the HD4800 series on June 25, 2008. Other variants include enthusiast-oriented RV790, mainstream product RV730, RV740 and entry-level RV710.
