In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 480 PowerColor Red Devil 8GB are noticeably better than the AMD Radeon HD 7950 Boost Edition Crossfire.

The RX 480 has a 270 MHz higher core clock speed than the HD 7950, but the HD 7950 has 80 more Texture Mapping Units than the RX 480. As a result, the HD 7950 exhibits a 29.1 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 270 MHz higher core clock speed than the HD 7950, but the HD 7950 has 32 more Render Output Units than the RX 480. As a result, the HD 7950 exhibits a 18.6 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 over three years more recently than the HD 7950, and so the RX 480 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 7950 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 RX 480 has 2048 MB more video memory than the HD 7950, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The HD 7950 has 224 GB/sec greater memory bandwidth than the RX 480, which means that the memory performance of the HD 7950 is massively better than the RX 480.

The Radeon RX 480 PowerColor Red Devil 8GB has 2304 Shader Processing Units and the Radeon HD 7950 Boost Edition Crossfire has 3584. However, the actual shader performance of the RX 480 is 3064 and the actual shader performance of the HD 7950 is 2818. The RX 480 having 246 better shader performance is not particularly notable, as altogether the HD 7950 performs better when taking into account other relevant data.

The RX 480 transistor size technology is 14 nm (nanometers) smaller than the HD 7950. This means that the RX 480 is expected to run slightly cooler and achieve higher clock frequencies than the HD 7950.

The Radeon RX 480 PowerColor Red Devil 8GB requires 150 Watts to run but there is no entry for the Radeon HD 7950 Boost Edition Crossfire. We would recommend a PSU with at least 500 Watts for the RX 480.

GPU Mini Review

Mini ReviewOverview
The Radeon RX 480 Red Devil 8GB by PowerColor is a Performance Graphics Card based on the Third Revision of the Graphics Core Next (GCN) Architecture. It is their top model of the RX 480 series featuring a massive boost to it's clock speed and a massive 3 fan non-stock cooling system. It is one of the best RX 480s available at the moment with a lot of overclocking potential.

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.

GPU
The Central Unit runs at 1120MHz and goes up to 1330MHz, in Turbo Mode.

Memory
The GPU accesses a 8GB frame buffer of Fast GDDR5, through a 256-bit memory interface, while the Memory Clock Operates at 2000MHz.

Power Consumption
With a rated board TDP of 150W, it requires at least a 500W PSU with one available 8-pin connector.

Performance
Benchmarks Indicate Radeon RX 480 8GB can be almost 10% Faster than GeForce GTX 970 at 4K. However, Radeon R9 390X is still slightly faster, overall.
At 1920x1080, the default rank for all GD Graphics Card, expect its performance to be between Radeonn R9 290 and Radeon R9 290X.

System Suggestions
Radeon RX 480 8GB is best suited for resolutions up to and including 2560x1440. We recommend a High-End Processor and 8GB of RAM for Optimal Performance.
