Game Radeon R9 270X Sapphire Dual-X 4GB OC Edition Radeon HD 5750 1024MB

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270X Sapphire Dual-X 4GB OC Edition are massively better than the AMD Radeon HD 5750 1024MB.

The R9 270X has a 320 MHz higher core clock speed and 44 more Texture Mapping Units than the HD 5750. This results in the R9 270X providing 56.4 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 R9 270X has a 320 MHz higher core clock speed and 16 more Render Output Units than the HD 5750. This results in the R9 270X providing 21.4 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 R9 270X was released over three years more recently than the HD 5750, and so the R9 270X is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 5750 when running the latest games.

The R9 270X has 3072 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 R9 270X also has superior memory performance overall.

The R9 270X has 105.6 GB/sec greater memory bandwidth than the HD 5750, which means that the memory performance of the R9 270X is massively better than the HD 5750.

The Radeon R9 270X Sapphire Dual-X 4GB OC Edition has 1280 Shader Processing Units and the Radeon HD 5750 1024MB has 720. However, the actual shader performance of the R9 270X is 1164 and the actual shader performance of the HD 5750 is 328. The R9 270X having 836 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 270X delivers a massively smoother and more efficient experience when processing graphical data than the HD 5750.

The R9 270X transistor size technology is 12 nm (nanometers) smaller than the HD 5750. This means that the R9 270X is expected to run slightly cooler and achieve higher clock frequencies than the HD 5750.

The Radeon R9 270X Sapphire Dual-X 4GB OC Edition requires 180 Watts to run and the Radeon HD 5750 1024MB requires 86 Watts. We would recommend a PSU with at least 500 Watts for the R9 270X and a PSU with at least 450 Watts for the HD 5750. The R9 270X requires 94 Watts more than the HD 5750 to run. The difference is significant enough that the R9 270X may have an adverse affect on your yearly electricity bills in comparison to the HD 5750.

GPU Mini Review

Mini ReviewRadeon R9 270X Sapphire Dual-X 4GB OC Edition is a special edition of the high-end Radeon R9 270X.
This edition comes with a custom cooling system called "Vapor-X", which reduces the card's temperature under load, significantly and comes overclocked out of the box in the central unit that was increased from 1000MHz to 1020MHz, while the Boost clock is now of 1070MHz.
Furthermore, the card has twice as much memory when compared to the reference card. However, this card will not benefit from extra memory and thus such feature ends up being useless.
Expect little or no performance boost over the standard edition and exactly the same performance as "Radeon R9 270X Sapphire Dual-X 2GB OC Edition"
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.
