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 X1800 Series 256MB.

The HD 7750 was released over three years more recently than the X1800 Series, 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 X1800 Series when running the latest games.

The HD 7750 has 768 MB more video memory than the X1800 Series, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The X1800 Series has 19.2 GB/sec greater memory bandwidth than the HD 7750, which means that the memory performance of the X1800 Series is slightly better than the HD 7750.

The Radeon HD 7750 VTX3D 1GB DDR3 Edition has 512 Shader Processing Units and the Radeon X1800 Series 256MB has 16. However, the actual shader performance of the HD 7750 is 348 and the actual shader performance of the X1800 Series is 5. The HD 7750 having 343 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7750 delivers a noticeably smoother and more efficient experience when processing graphical data than the X1800 Series.

We would recommend a PSU with at least 400 Watts for the HD 7750 and a PSU with at least 450 Watts for the X1800 Series. The X1800 Series has been recommended a PSU with 50 Watts more than the HD 7750. The difference is significant enough that the X1800 Series may have a slight adverse affect on your yearly electricity bills in comparison to the HD 7750.

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.
Radeon X1800 Series 256MB is not a GPU but instead a combination between Radeon X1800 GTO, Radeon X1800 XL and Radeon X1800 XT whose rank is a balance between the three and that exists for System Requirements purposes only.
