In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 470 XFX RS Black Edition 4GB are significantly better than the AMD Radeon HD 7870 DirectCU II 2GB Edition.

The HD 7870 has a 84 MHz higher core clock speed than the RX 470, but the RX 470 has 16 more Texture Mapping Units than the HD 7870. As a result, the RX 470 exhibits a 8.1 GTexel/s better Texture Fill Rate than the HD 7870. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7870 has a 84 MHz higher core clock speed than the RX 470, but the RX 470 has 16 more Render Output Units than the HD 7870. As a result, the RX 470 exhibits a 12.1 GPixel/s better Pixel Fill Rate than the HD 7870. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX 470 was released over three years more recently than the HD 7870, and so the RX 470 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 7870 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 470 has 2048 MB more video memory than the HD 7870, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the RX 470 also has superior memory performance overall.

The RX 470 has 69.1 GB/sec greater memory bandwidth than the HD 7870, which means that the memory performance of the RX 470 is much better than the HD 7870.

The Radeon RX 470 XFX RS Black Edition 4GB has 2048 Shader Processing Units and the Radeon HD 7870 DirectCU II 2GB Edition has 1280. However, the actual shader performance of the RX 470 is 2572 and the actual shader performance of the HD 7870 is 1099. The RX 470 having 1473 better shader performance and an altogether better performance when taking into account other relevant data means that the RX 470 delivers a massively smoother and more efficient experience when processing graphical data than the HD 7870.

The RX 470 transistor size technology is 14 nm (nanometers) smaller than the HD 7870. This means that the RX 470 is expected to run slightly cooler and achieve higher clock frequencies than the HD 7870.

The Radeon RX 470 XFX RS Black Edition 4GB requires 120 Watts to run but there is no entry for the Radeon HD 7870 DirectCU II 2GB Edition. We would recommend a PSU with at least 450 Watts for the RX 470.

GPU Mini Review

Mini ReviewOverview
Radeon RX 470 4GB XFX Black Edition is a dual fan, standard form factor performance graphics card, based on the fourth revision of the Graphics Core Next (GCN) Architecture.

Architecture
N/A.

GPU
It equips a GPU Codenamed Ellesmere PRO which has 2048 Shader Processing Units, 128 TMUs and 32 ROPs.

Memory
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.

Performance
The XFX RS Black Edition RX 470 should run most modern 2016 AAA games at 1080p on high graphics settings.

System Suggestions
Radeon RX 470 4GB is best suited for resolutions up to and including 1920x1080. We recommend a Performance Processor and 8GB of RAM for Optimal Performance.
Radeon HD 7870 DirectCU II 2GB Edition is a special edition of the powerful Radeon HD 7870. See the standard version for more information about it.
The new features include the DirectCU II cooling solution which is 20% more effective than the reference cooler, according to Asus and a small increase in the core-clock to 1010MHz as well as in the memory clock to 1210MHz.
Benchmarks indicate almost no performance boost when compared to the standard Radeon HD 7870 and so its performance is on level with the it as the boost is beneath 1%.
All games, including demanding one's, will run on the highest settings.
