In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 480X 8GB are very slightly better than the AMD Radeon HD 7950 3-way Crossfire.

The RX 480X has a 450 MHz higher core clock speed than the HD 7950, but the HD 7950 has 208 more Texture Mapping Units than the RX 480X. As a result, the HD 7950 exhibits a 108.8 GTexel/s better Texture Fill Rate than the RX 480X. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RX 480X has a 450 MHz higher core clock speed but 32 fewer Render Output Units than the HD 7950. The lower ROP count doesn't matter, though, as altogether the RX 480X manages to provide 3.2 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 480X was released over three years more recently than the HD 7950, and so the RX 480X 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 HD 7950 has 1024 MB more video memory than the RX 480X, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7950 also has superior memory performance overall.

The HD 7950 has 720 GB/sec greater memory bandwidth than the RX 480X, which means that the memory performance of the HD 7950 is massively better than the RX 480X.

The Radeon RX 480X 8GB has 2048 Shader Processing Units and the Radeon HD 7950 3-way Crossfire has 5376. However, the actual shader performance of the RX 480X is 2560 and the actual shader performance of the HD 7950 is 3656. The HD 7950 having 1096 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7950 delivers a massively smoother and more efficient experience when processing graphical data than the RX 480X.

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

The Radeon RX 480X 8GB requires 150 Watts to run and the Radeon HD 7950 3-way Crossfire requires 540 Watts. We would recommend a PSU with at least 500 Watts for the RX 480X. The HD 7950 requires 390 Watts more than the RX 480X to run. The difference is significant enough that the HD 7950 may have an adverse affect on your yearly electricity bills in comparison to the RX 480X.

GPU Mini Review

Mini ReviewOverview
Radeon RX 480X 8GB is an Upcoming High-End Graphics Card based on the Third Revision of the Graphics Core Next (GCN) Architecture.

Architecture
N/A.

GPU
It equips a GPU Codenamed Ellesmere XT which has 32 SM activated and thus 2048 Shader Processing Units, 128 TMUs and 64 ROPs. The central unit runs at 1250MHz and goes up to 1350MHz, in Turbo Mode.

Memory
The GPU accesses a 8GB frame buffer of Second Gen GDDR5X, through a 256-bit memory interface, while the Memory Clock Operates at 1750MHz.

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

Performance
N/A.

System Suggestions
Radeon RX 480X 8GB is best suited for resolutions up to and including 2560x1600. We recommend a High-End Processor and 8GB of RAM for Optimal Performance.
Radeon HD 7950 3-way Crossfire is a solution of three Radeon HD 7950 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 7950 to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is somewhat superior to a single Radeon HD 7990 performing by itself it might be worse (depending on whether or not the 3D game supports crossfire or in the graphics driver) than a single Radeon HD 7950. Expect this combination to draw up to 540 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
