In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 390X Sapphire Nitro w/ Back Plate 8GB Edition are significantly better than the AMD Radeon RX 460 4GB.

The RX 460 has a 30 MHz higher core clock speed than the R9 390X, but the R9 390X has 120 more Texture Mapping Units than the RX 460. As a result, the R9 390X exhibits a 125.6 GTexel/s better Texture Fill Rate than the RX 460. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RX 460 has a 30 MHz higher core clock speed than the R9 390X, but the R9 390X has 48 more Render Output Units than the RX 460. As a result, the R9 390X exhibits a 50.4 GPixel/s better Pixel Fill Rate than the RX 460. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX 460 was released over a year more recently than the R9 390X, and so the RX 460 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the R9 390X.

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 4096 MB more video memory than the RX 460, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 390X also has superior memory performance overall.

The R9 390X has 384 GB/sec greater memory bandwidth than the RX 460, which means that the memory performance of the R9 390X is massively better than the RX 460.

The Radeon RX 460 4GB has 896 Shader Processing Units and the Radeon R9 390X Sapphire Nitro w/ Back Plate 8GB Edition has 2816. However, the actual shader performance of the RX 460 is 1075 and the actual shader performance of the R9 390X is 2537. The R9 390X having 1462 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 390X delivers a massively smoother and more efficient experience when processing graphical data than the RX 460.

The RX 460 transistor size technology is 14 nm (nanometers) smaller than the R9 390X. This means that the RX 460 is expected to run slightly cooler and achieve higher clock frequencies than the R9 390X.

The Radeon RX 460 4GB requires 75 Watts to run and the Radeon R9 390X Sapphire Nitro w/ Back Plate 8GB Edition requires 375 Watts. We would recommend a PSU with at least 350 Watts for the RX 460 and a PSU with at least 750 Watts for the R9 390X. The R9 390X requires 300 Watts more than the RX 460 to run. The difference is significant enough that the R9 390X may have an adverse affect on your yearly electricity bills in comparison to the RX 460.

GPU Mini Review

Mini ReviewOverview
Radeon RX 460 4GB is an Middle-Class Graphics Card based on the 4th Generation of the Graphics Core Next (GCN) Architecture.

GPU
It equips a GPU Codenamed Baffin XT which has 14 Compute Units activated and thus 896 Shader Processing Units, 56 TMUs and 16 ROPs.

Memory
The GPU accesses a 4GB frame buffer of Fast GDDR5, through a 128-bit memory interface, while the Memory Clock Operates at 1750MHz.

Power Consumption
With a rated board TDP of 75W, it requires at least a 350W PSU and relies entirely on the PCI Slot for Power, meaning no Extra Connectors are required.

Performance
This graphics card was designed and marketed towards the competitive MOBO gamers. A light weight, small form factor GPU solution that offers mobility, so that gamers travelling to events can bring a smaller cheaper gaming rig. The Radeon RX 460 4GB can play most modern games at medium graphics selection on a 1600p screen res and expect around 45+FPS

System Suggestions
Radeon RX 460 4GB is best suited for resolutions up to and including 1600x900. We recommend a Performance Processor and 8GB of RAM for Optimal Performance.
Overview
Radeon R9 390X Sapphire Nitro w/ Back Plate 8GB Edition is a Special Edition of AMD's High-End Radeon R9 390X, created by Sapphire.

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

Overclock: Memory Clock
None.

Frame Buffer
Untouched.

Cooling Solution
Tri-X cooler Features dual ball bearings in each of the three fans for higher reliability and enhanced Intelligent Fan Control (IFC-II) which turns off the fans for silent operation under light load.
