In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 Ti 6GB are noticeably better than the AMD Radeon R9 390X Gigabyte G1 Gaming 8GB Edition.

The R9 390X has a 60 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 980 Ti. This results in the R9 390X providing 10.6 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 R9 390X has a 60 MHz higher core clock speed than the GTX 980 Ti, but the GTX 980 Ti has 32 more Render Output Units than the R9 390X. As a result, the GTX 980 Ti exhibits a 28.2 GPixel/s better Pixel Fill Rate than the R9 390X. 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 Ti, 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 R9 390X has 2048 MB more video memory than the GTX 980 Ti, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The R9 390X has 47.4 GB/sec greater memory bandwidth than the GTX 980 Ti, which means that the memory performance of the R9 390X is noticeably better than the GTX 980 Ti.

Both the Radeon R9 390X Gigabyte G1 Gaming 8GB Edition and the GeForce GTX 980 Ti 6GB have 2816 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GTX 980 Ti is 4091 and by the R9 390X is 4091. Knowing that the shader performance of the GTX 980 Ti is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Radeon R9 390X Gigabyte G1 Gaming 8GB Edition requires 300 Watts to run and the GeForce GTX 980 Ti 6GB requires 250 Watts. We would recommend a PSU with at least 600 Watts for the R9 390X and a PSU with at least 600 Watts for the GTX 980 Ti. The R9 390X requires 50 Watts more than the GTX 980 Ti to run. The difference is significant enough that the R9 390X may have a slight adverse affect on your yearly electricity bills in comparison to the GTX 980 Ti.

GPU Mini Review

Mini ReviewOverview
Radeon R9 390X Gigabyte G1 Gaming 8GB Edition is a Special Edition of AMD's High-End Radeon R9 390X, created by Gigabyte.

Overclock: Central Unit
The Central Unit is now of 1060MHz, instead of 1050MHz.

Overclock: Memory Clock
None.

Frame Buffer
Untouched.

Cooling Solution
WINDFORCE 2X Cooling System: The airflow is spilt through the triangle design at the fan edge, and is guided smoothly through the fan by special 3D stripe curve design. At the same time, it effectively enhanced the cooling capacity while reducing air turbulence.

Performance
Benchmarks Indicate no Performance Boost over the Reference Radeon R9 390X 8GB.
Overview
GeForce GTX 980 Ti 6GB is an Enthusiast Graphics Card based on the second revision of the Maxwell architecture.

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.
The Second Revision of Maxwell also adds VXGI (Voxel Global Illumination) which makes scenes significantly more lifelike and believable as light interacts more realistically in the game environment and the MFAA technology which provides the same effect as MSAA but at a much lower performance cost.

GPU
It equips a GPU codenamed GM200-310-A1 which has 22 SM activated and thus 2816 Shader Processing Units, 176 TMUs and 96 ROPs. The central unit runs at 1000MHz and goes up to 1076MHz, in Turbo Mode.

Memory
The GPU accesses a 6GB frame buffer of fast GDDR5, through a 384-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1753MHz.

Power Consumption
With a rated board TDP of 250W, it requires at least a 600W PSU with one available 6-pin and one available 8-pin connectors.

Performance
Benchmarks Indicate its performance is slightly above AMD's Dual Radeon R9 295X2 at 1920x1080 but at any resolution above that, the latter proves to be faster.
As expected, $999 GeForce GTX Titan X is also slightly faster but GeForce GTX 980 is beaten in around 20%.
Even so, GeForce GTX 980 Ti 6GB is not a competitive product because a solution of two GeForce GTX 970 in SLI is still much faster and doesn't come at a much higher cost ($658 against $649).

System Suggestions
GeForce GTX 980 Ti 6GB is best suited for resolutions up to and including 2560x1600. We recommend a Very Strong Processor and 16GB of RAM for Optimal Performance.
