In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 490X 8GB are massively better than the Nvidia GeForce GTX 960 Zotac v2 2GB Edition.

The GTX 960 has a 177 MHz higher core clock speed than the RX 490X, but the RX 490X has 320 more Texture Mapping Units than the GTX 960. As a result, the RX 490X exhibits a 308.7 GTexel/s better Texture Fill Rate than the GTX 960. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 960 has a 177 MHz higher core clock speed than the RX 490X, but the RX 490X has 96 more Render Output Units than the GTX 960. As a result, the RX 490X exhibits a 90.3 GPixel/s better Pixel Fill Rate than the GTX 960. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX 490X was released over a year more recently than the GTX 960, and so the RX 490X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 960.

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 RX 490X has 6144 MB more video memory than the GTX 960, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 960 has superior memory performance.

The GTX 960 has 112.2 GB/sec greater memory bandwidth than the RX 490X, which means that the memory performance of the GTX 960 is massively better than the RX 490X.

The Radeon RX 490X 8GB has 6144 Shader Processing Units and the GeForce GTX 960 Zotac v2 2GB Edition has 1024. However, the actual shader performance of the GTX 960 is 1714. The RX 490X having 4430 better shader performance and an altogether better performance when taking into account other relevant data means that the RX 490X delivers a massively smoother and more efficient experience when processing graphical data than the GTX 960.

The RX 490X transistor size technology is 14 nm (nanometers) smaller than the GTX 960. This means that the RX 490X is expected to run slightly cooler and achieve higher clock frequencies than the GTX 960.

The Radeon RX 490X 8GB requires 250 Watts to run and the GeForce GTX 960 Zotac v2 2GB Edition requires 120 Watts. We would recommend a PSU with at least 600 Watts for the RX 490X and a PSU with at least 400 Watts for the GTX 960. The RX 490X requires 130 Watts more than the GTX 960 to run. The difference is significant enough that the RX 490X may have an adverse affect on your yearly electricity bills in comparison to the GTX 960.

GPU Mini Review

Mini ReviewOverview
Radeon RX 490X 8GB is an Upcoming High-End Graphics Card based on the Third Revision of the Graphics Core Next (GCN) Architecture.



The GPU accesses a 8GB frame buffer of Second Generation HBM, through a 4096-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 500MHz.

Power Consumption


System Suggestions
Radeon RX 490X 8GB is best suited for resolutions up to and including 3840x2160. We recommend a High-End Processor and 16GB of RAM for Optimal Performance.
GeForce GTX 960 Zotac v2 2GB Edition is a Special Edition of NVIDIA's Performance GeForce GTX 960 2GB, created by Zotac.

Overclock: Central Unit
The Central Unit now runs at 1177MHz, instead of 1127MHz and goes up to 1240MHz, in Turbo Mode.

Overclock: Memory Clock
The Operating Memory Clock and the Frame Buffer remain the same.

Cooling Solution
The reference NVIDIA Single-Fan Cooling System has been replaced by Zotac's Dual Fan Cooling Solution. This means the card runs cooler under load.

Benchmarks indicate a 2% performance over the reference GeForce GTX 960 2GB.
