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

The HD 7870 has a 224 MHz higher core clock speed than the RX 470, but the RX 470 has 48 more Texture Mapping Units than the HD 7870. As a result, the RX 470 exhibits a 26.5 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 224 MHz higher core clock speed than the RX 470 and the same number of Render Output Units. This results in the HD 7870 providing 7.2 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 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 64 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 Limited Edition 4GB has 2048 Shader Processing Units and the Radeon HD 7870 PCS+ Vortex II Edition has 1280. However, the actual shader performance of the RX 470 is 2621 and the actual shader performance of the HD 7870 is 1251. The RX 470 having 1370 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 Limited Edition 4GB requires 120 Watts to run but there is no entry for the Radeon HD 7870 PCS+ Vortex II Edition. We would recommend a PSU with at least 450 Watts for the RX 470 and a PSU with at least 500 Watts for the HD 7870. The HD 7870 has been recommended a PSU with 50 Watts more than the RX 470. The difference is significant enough that the HD 7870 may have a slight adverse affect on your yearly electricity bills in comparison to the RX 470.

GPU Mini Review

Mini ReviewOverview
The AMD Radeon RX 470 XFX RS Black Limited Edition 4GB graphics card is a 2016 released performance graphics card based on the third revision of the Graphics Core Next (GCN) architecture and is the best choice of the 4GB RX 470 cards. This card competes against Nvidia's outgoing, but very popular, GTX 970 and the incoming GTX 1050 Ti, when that releases.

Architecture
It is powered by the Ellesmere PRO GPU, which has 2048 shader processing units, 128 TMUs and 32 ROPs.

GPU
The central unit runs at 926MHz and goes up to 1280MHz, when boost mode is triggered, the highest of any RX 470.

Memory
The GPU accesses a 4GB frame buffer of GDDR5, through a 256-bit memory interface, while the memory clock Operates at a boosted 1750MHz, the highest the RX 470s 4GB cards go up to.

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

Performance
The AMD RX 470 has been built as a Mid/High performance graphics card for 2016 and so the Radeon RX 470 XFX RS Black Limited Edition 4GB will really show the best the RX 470 can do. It will run most triple AAA titles released during 2016 on medium to high graphics at 1080p screen resolution. With adjustments and lowering anti aliasing this card can confidently maintain 60+ frames per seconds on high graphic settings at 1080p. Moving to 1440p screen resolution and the graphics card may need to be adjusted down to medium in order to maintain 50-60+ fps.

System Suggestions
The RX 470 is best suited for resolutions up to and including 1920x1080. We recommend a mid range processor and at least 8GB of system memory for optimal performance.
Radeon HD 7870 PCS+ Vortex II Edition is a special edition of Radeon HD 7870.
This is one of today's most powerful editions of the reference as it features increases in both the core and memory clocks that went from 1000MHz to 1150MHz and from 1200MHz to 1250MHz.
Benchmarks indicate the performance boost is quite extreme and around 8% when compared to the reference Radeon HD 7870.
