In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 480 4GB are marginally better than the AMD Radeon R9 390X Sapphire Nitro w/ Back Plate 8GB Edition.

The RX 480 has a 60 MHz higher core clock speed than the R9 390X, but the R9 390X has 32 more Texture Mapping Units than the RX 480. As a result, the R9 390X exhibits a 25.3 GTexel/s better Texture Fill Rate than the RX 480. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RX 480 has a 60 MHz higher core clock speed than the R9 390X, but the R9 390X has 32 more Render Output Units than the RX 480. As a result, the R9 390X exhibits a 32 GPixel/s better Pixel Fill Rate than the RX 480. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX 480 was released less than a year after the R9 390X, 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 4096 MB more video memory than the RX 480, 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 160 GB/sec greater memory bandwidth than the RX 480, which means that the memory performance of the R9 390X is massively better than the RX 480.

The Radeon R9 390X Sapphire Nitro w/ Back Plate 8GB Edition has 2816 Shader Processing Units and the Radeon RX 480 4GB has 2304. However, the actual shader performance of the R9 390X is 2537 and the actual shader performance of the RX 480 is 2917. The RX 480 having 380 better shader performance is not particularly notable, as altogether the R9 390X performs better when taking into account other relevant data.

The RX 480 transistor size technology is 14 nm (nanometers) smaller than the R9 390X. This means that the RX 480 is expected to run slightly cooler and achieve higher clock frequencies than the R9 390X.

The Radeon R9 390X Sapphire Nitro w/ Back Plate 8GB Edition requires 375 Watts to run and the Radeon RX 480 4GB requires 120 Watts. We would recommend a PSU with at least 750 Watts for the R9 390X and a PSU with at least 450 Watts for the RX 480. The R9 390X requires 255 Watts more than the RX 480 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 480.

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.

Benchmarks Indicate no Significant Performance Boost over the Reference Radeon R9 390X 8GB.
Radeon RX 480 4GB is a Performance Graphics Card based on the Third Revision of the Graphics Core Next (GCN) Architecture.

It equips a GPU Codenamed Ellesmere XT which is a Forth Gen GCN GPU and has 36 SM activated and thus offers 2304 Shader Processing Units, 144 TMUs and 32 ROPs.

The Central Unit runs at 1120MHz and goes up to 1266MHz, in Turbo Mode.

The GPU accesses a 4GB frame buffer of Fast GDDR5, through a 256-bit memory interface, while the Memory Clock Operates at 1750MHz.

Power Consumption
With a rated board TDP of 120W, it requires at least a 450W PSU with one available 6-pin connector.

Benchmarks Indicate Radeon RX 480 4GB is, on average, as fast as GeForce GTX 970.

System Suggestions
Radeon RX 480 4GB is best suited for resolutions up to and including 1920x1080. We recommend a High-End Processor and 8GB of RAM for Optimal Performance.
