In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 5550 512MB are marginally better than the AMD Radeon HD 3800 series.

The HD 3800 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The HD 5550 was released over a year more recently than the HD 3800, and so the HD 5550 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 3800.

The Radeon HD 5550 512MB and the Radeon HD 3800 series have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 5550 has 64 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the HD 5550 is much better than the HD 3800.

Both the Radeon HD 5550 512MB and the Radeon HD 3800 series have 320 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the HD 5550 is 114 and by the HD 3800 is 0. Knowing that the shader performance of the HD 5550 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The HD 5550 transistor size technology is 15 nm (nanometers) smaller than the HD 3800. This means that the HD 5550 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3800. While they exhibit similar graphical performance, the HD 5550 should consume less power than the HD 3800.

The Radeon HD 5550 512MB requires 39 Watts to run but there is no entry for the Radeon HD 3800 series. We would recommend a PSU with at least 400 Watts for the HD 5550.

GPU Mini Review

Mini ReviewThe 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.
Radeon HD 3800 Series is not a GPU but instead a combination between Radeon HD 3830, Radeon HD 3850 and Radeon HD 3870 whose rank is a balance between the three and that exists for System Requirements purposes only.
