In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7870 PCS+ Vortex II Edition are massively better than the AMD Radeon HD 5750 512MB.

The HD 7870 has a 450 MHz higher core clock speed and 44 more Texture Mapping Units than the HD 5750. This results in the HD 7870 providing 66.8 GTexel/s better texturing performance. 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 450 MHz higher core clock speed and 16 more Render Output Units than the HD 5750. This results in the HD 7870 providing 25.6 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 HD 7870 was released over a year more recently than the HD 5750, and so the HD 7870 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 5750.

The HD 7870 has 1536 MB more video memory than the HD 5750, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7870 also has superior memory performance overall.

The HD 7870 has 86.4 GB/sec greater memory bandwidth than the HD 5750, which means that the memory performance of the HD 7870 is much better than the HD 5750.

The Radeon HD 7870 PCS+ Vortex II Edition has 1280 Shader Processing Units and the Radeon HD 5750 512MB has 720. However, the actual shader performance of the HD 7870 is 1251 and the actual shader performance of the HD 5750 is 328. The HD 7870 having 923 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7870 delivers a massively smoother and more efficient experience when processing graphical data than the HD 5750.

The HD 7870 transistor size technology is 12 nm (nanometers) smaller than the HD 5750. This means that the HD 7870 is expected to run slightly cooler and achieve higher clock frequencies than the HD 5750.

The Radeon HD 5750 512MB requires 86 Watts to run but there is no entry for the HD 7870. We would recommend a PSU with at least 500 Watts for the HD 7870 and a PSU with at least 450 Watts for the HD 5750. The HD 7870 has been recommended a PSU with 50 Watts more than the HD 5750. The difference is significant enough that the HD 7870 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 5750.

GPU Mini Review

Mini ReviewRadeon 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.
The Evergreen series is a family of GPUs developed by AMD graphics products division. The existence was spotted on a presentation slide from AMD Technology Analyst Day July 2007 as 'R8xx'. ATI held a press event in the USS Hornet museum on September 10, 2009 and announced ATI Eyefinity multi-display technology and specifications of the Radeon HD 5800 series' variants. The first variants of the Radeon HD 5800 series were launched September 23, 2009, with the HD 5700 series launching October 12 and HD 5970 launching on November 18 The HD 5670, was launched on January 14, 2010, and the HD 5500 and 5400 series were launched in February of 2010, completing what has appeared to be most of ATI's Evergreen GPU lineup.
Demand so greatly outweighed supply that more than two months after launch, many online retailers were still having trouble keeping the 5800 and 5900 series in stock.
