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 4550.

The HD 7750 has a 200 MHz higher core clock speed and 24 more Texture Mapping Units than the Radeon HD 4550. This results in the HD 7750 providing 20.8 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 7750 has a 200 MHz higher core clock speed and 12 more Render Output Units than the Radeon HD 4550. This results in the HD 7750 providing 10.4 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 HD 7750 was released over three years more recently than the Radeon HD 4550, and so the HD 7750 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon HD 4550 when running the latest games.

The HD 7750 has 768 MB more video memory than the Radeon HD 4550, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7750 also has superior memory performance overall.

The HD 7750 has 12.8 GB/sec greater memory bandwidth than the Radeon HD 4550, which means that the memory performance of the HD 7750 is slightly better than the Radeon HD 4550.

The Radeon HD 7750 VTX3D 1GB DDR3 Edition has 512 Shader Processing Units and the Radeon HD 4550 has 80. However, the actual shader performance of the HD 7750 is 348 and the actual shader performance of the Radeon HD 4550 is 34. The HD 7750 having 314 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 Radeon HD 4550.

The HD 7750 transistor size technology is 27 nm (nanometers) smaller than the Radeon HD 4550. This means that the HD 7750 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 4550.

The Radeon HD 4550 requires 25 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 300 Watts for the Radeon HD 4550. The HD 7750 has been recommended a PSU with 100 Watts more than the Radeon HD 4550. The difference is significant enough that the HD 7750 may have an adverse affect on your yearly electricity bills in comparison to the Radeon HD 4550.

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 Radeon R700 is the engineering codename for a graphics processing unit series released by AMD Graphics Product Group, sold under the ATI brand. The foundation chip, codenamed RV770, was announced and demonstrated on June 16, 2008 as part of the FireStream 9250 and Cinema 2.0 initiative launch media event, with official release of the HD4800 series on June 25, 2008. Other variants include enthusiast-oriented RV790, mainstream product RV730, RV740 and entry-level RV710.
