In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7750 VTX3D 1GB DDR3 Edition are massively better than the AMD Radeon HD 5450 1024MB.

The HD 7750 has a 150 MHz higher core clock speed and 24 more Texture Mapping Units than the HD 5450. This results in the HD 7750 providing 20.4 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 HD 7750 has a 150 MHz higher core clock speed and 12 more Render Output Units than the HD 5450. This results in the HD 7750 providing 10.2 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 HD 7750 was released over a year more recently than the HD 5450, and so the HD 7750 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 5450.

The Radeon HD 7750 VTX3D 1GB DDR3 Edition and the Radeon HD 5450 1024MB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 7750 has 19.2 GB/sec greater memory bandwidth than the HD 5450, which means that the memory performance of the HD 7750 is slightly better than the HD 5450.

The Radeon HD 7750 VTX3D 1GB DDR3 Edition has 512 Shader Processing Units and the Radeon HD 5450 1024MB has 80. However, the actual shader performance of the HD 7750 is 348 and the actual shader performance of the HD 5450 is 52. The HD 7750 having 296 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7750 delivers a significantly smoother and more efficient experience when processing graphical data than the HD 5450.

The HD 7750 transistor size technology is 12 nm (nanometers) smaller than the HD 5450. This means that the HD 7750 is expected to run slightly cooler and achieve higher clock frequencies than the HD 5450.

The Radeon HD 5450 1024MB requires 19 Watts to run but there is no entry for the HD 7750. We would recommend a PSU with at least 400 Watts for the HD 7750 and a PSU with at least 400 Watts for the HD 5450. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon HD 7750 VTX3D 1GB DDR3 Edition is a special edition of the fast-middle-class Radeon HD 7750 1GB DDR3.
This version has no new features (when compared to the DDR3 version) and so it performs exactly like it.
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.
