In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1080 are marginally better than the AMD Radeon RX 490 8GB.

The GeForce GTX 1080 has a 557 MHz higher core clock speed than the RX 490, but the RX 490 has 96 more Texture Mapping Units than the GeForce GTX 1080. As a result, the RX 490 exhibits a 11.7 GTexel/s better Texture Fill Rate than the GeForce GTX 1080. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GTX 1080 has a 557 MHz higher core clock speed than the RX 490 and the same number of Render Output Units. This results in the GeForce GTX 1080 providing 35.6 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 RX 490 was released less than a year after the GeForce GTX 1080, 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 RX 490 8GB and the GeForce GTX 1080 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The RX 490 has 703.7 GB/sec greater memory bandwidth than the GeForce GTX 1080, which means that the memory performance of the RX 490 is massively better than the GeForce GTX 1080.

The Radeon RX 490 8GB has 4096 Shader Processing Units and the GeForce GTX 1080 has 2560. However, the actual shader performance of the RX 490 is 4301 and the actual shader performance of the GeForce GTX 1080 is 5989. The GeForce GTX 1080 having 1688 better shader performance is not particularly notable, as altogether the RX 490 performs better when taking into account other relevant data.

The RX 490 transistor size technology is 2 nm (nanometers) smaller than the GeForce GTX 1080. This means that the RX 490 is expected to run very slightly cooler and achieve higher clock frequencies than the GeForce GTX 1080.

The Radeon RX 490 8GB requires 225 Watts to run and the GeForce GTX 1080 requires 180 Watts. We would recommend a PSU with at least 550 Watts for the RX 490 and a PSU with at least 500 Watts for the GeForce GTX 1080. The RX 490 requires 45 Watts more than the GeForce GTX 1080 to run. The difference is significant enough that the RX 490 may have a slight adverse affect on your yearly electricity bills in comparison to the GeForce GTX 1080.

GPU Mini Review

Mini ReviewOverview
Radeon RX 490 8GB is an upcoming high-end performance Graphics Card based on the Third Revision of the Graphics Core Next (GCN) Architecture.

Architecture
N/A.

GPU
N/A.

Memory
The GPU accesses a 8GB frame buffer of Second Generation HBM, through a 8192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 500MHz.

Power Consumption
As a dual slot graphics card this should be in the region of 225W

Performance
The RX 490 will be capable of running 2016 released AAA games on High-Ultra graphics settings using a 1440p resolution. In some cases it will also be capable of running a number of modern games at 4K resolution with a reliable frame rate at High graphics settings

System Suggestions
Radeon RX 490 8GB is best suited for resolutions up to and including 2560x1440. We recommend a High-End Processor and 16GB of RAM for Optimal Performance.
Overview
GeForce GTX 1080 is a High-End Graphics Card based on the Pascal Architecture.

Architecture
