In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 4GB SLI are significantly better than the AMD Radeon R9 390X HIS IceQ X OC 8GB Edition.

The GTX 980 has a 56 MHz higher core clock speed and 80 more Texture Mapping Units than the R9 390X. This results in the GTX 980 providing 100 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 56 MHz higher core clock speed and 64 more Render Output Units than the R9 390X. This results in the GTX 980 providing 75.6 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 R9 390X was released less than a year after the GTX 980, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The Radeon R9 390X HIS IceQ X OC 8GB Edition and the GeForce GTX 980 4GB SLI have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 980 has 64.8 GB/sec greater memory bandwidth than the R9 390X, which means that the memory performance of the GTX 980 is much better than the R9 390X.

The Radeon R9 390X HIS IceQ X OC 8GB Edition has 2816 Shader Processing Units and the GeForce GTX 980 4GB SLI has 4096. However, the actual shader performance of the R9 390X is 2561 and the actual shader performance of the GTX 980 is 6724. The GTX 980 having 4163 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 R9 390X.

The Radeon R9 390X HIS IceQ X OC 8GB Edition requires 300 Watts to run and the GeForce GTX 980 4GB SLI requires 350 Watts. We would recommend a PSU with at least 750 Watts for the R9 390X and a PSU with at least 750 Watts for the GTX 980. The GTX 980 requires 50 Watts more than the R9 390X to run. The difference is significant enough that the GTX 980 may have a slight adverse affect on your yearly electricity bills in comparison to the R9 390X.

GPU Mini Review

Mini ReviewOverview
Radeon R9 390X HIS IceQ X OC 8GB Edition is a Special Edition of AMD's High-End Radeon R9 390X, created by HIS.

Overclock: Central Unit
The Central Unit is now of 1070MHz, instead of 1050MHz.

Overclock: Memory Clock
None.

Frame Buffer
Untouched.

Cooling Solution
IceQ X is one of the quietest coolers, making the card quieter than the reference cooler.

Performance
Benchmarks Indicate a 1% Performance Boost over the Reference Radeon R9 390X 8GB.
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.
