In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 550X 4GB are marginally better than the AMD Radeon HD 7950 VTX3D 3GB Boost X-Edition.

The RX 550X has a 210 MHz higher core clock speed than the HD 7950, but the HD 7950 has 56 more Texture Mapping Units than the RX 550X. As a result, the HD 7950 exhibits a 37.6 GTexel/s better Texture Fill Rate than the RX 550X. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RX 550X has a 210 MHz higher core clock speed than the HD 7950, but the HD 7950 has 16 more Render Output Units than the RX 550X. As a result, the HD 7950 exhibits a 10.8 GPixel/s better Pixel Fill Rate than the RX 550X. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX 550X was released over three years more recently than the HD 7950, and so the RX 550X 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 550X has 1024 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 240 GB/sec greater memory bandwidth than the RX 550X, which means that the memory performance of the HD 7950 is massively better than the RX 550X.

The Radeon RX 550X 4GB has 896 Shader Processing Units and the Radeon HD 7950 VTX3D 3GB Boost X-Edition has 1792. However, the actual shader performance of the RX 550X is 1075 and the actual shader performance of the HD 7950 is 1417. The HD 7950 having 342 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 550X.

The RX 550X transistor size technology is 14 nm (nanometers) smaller than the HD 7950. This means that the RX 550X is expected to run slightly cooler and achieve higher clock frequencies than the HD 7950.

The Radeon RX 550X 4GB requires 75 Watts to run but there is no entry for the Radeon HD 7950 VTX3D 3GB Boost X-Edition. We would recommend a PSU with at least 350 Watts for the RX 550X and a PSU with at least 500 Watts for the HD 7950. The HD 7950 has been recommended a PSU with 150 Watts more than the RX 550X. The difference is significant enough that the HD 7950 may have an adverse affect on your yearly electricity bills in comparison to the RX 550X.

GPU Mini Review

Mini ReviewOverview
The new AMD Radeon RX 500X series are an OEM version of the current RX 500 series. Radeon RX 550X 4GB is an Middle-Class Graphics Card based on the 4th Generation of the Graphics Core Next (GCN) Architecture. The specs of the Radeon RX 500X series graphics cards are identical to the standard Radeon RX 500 series.

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 550X 4GB can play most modern games at medium graphics selection on a 1600p screen res and expect around 45+FPS. Performance is exactly the same as the Radeon RX 550.

System Suggestions
Radeon RX 550X 4GB is best suited for resolutions up to and including 1600x900. We recommend a Performance Processor and 8GB of RAM for Optimal Performance.
Radeon HD 7950 VTX3D 3GB Boost X-Edition is a special edition of the high-end Radeon HD 7950 Boost Edition.
This edition comes with a custom cooling solution and overclocking out of the box in the core-clock that was increase by 30MHz to 880MHz. Therefore, the Turbo Boost is now of 930MHz.
Expect a 1.5% performance boost when compared to the reference Radeon HD 7950 Boost Edition.
