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 X1650 GT.

The HD 7750 was released over three years more recently than the Radeon X1650 GT, 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 X1650 GT when running the latest games.

The HD 7750 has 896 MB more video memory than the Radeon X1650 GT, 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 X1650 GT, which means that the memory performance of the HD 7750 is slightly better than the Radeon X1650 GT.

The Radeon X1650 GT has 24 Shader Processing Units and the Radeon HD 7750 VTX3D 1GB DDR3 Edition has 512. However, the actual shader performance of the Radeon X1650 GT is 6 and the actual shader performance of the HD 7750 is 348. The HD 7750 having 342 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 X1650 GT.

We would recommend a PSU with at least 400 Watts for the HD 7750, but we do not have a recommended PSU wattage for the Radeon X1650 GT.

GPU Mini Review

Mini ReviewRadeon X1650 GT is a middle-class GPU based on the 80nm variant of the R500 architecture.
It's based on the RV560 Core and offers 12 Pixel Shaders, 8 TMUs and 8 ROPs, on a 128-bit of standard GDDR3. The central unit runs at 400MHz and the memory clock operates at up to 400MHz.
It's expected to perform better than Radeon X1600 GPUs but the limited frame buffer might become a bottleneck in some of today's modern games and so it's not suited for them.
Some of today's games might be playable at medium settings although the low preset will have to be used on most. As it's not based on a Shader-Unified architecture, both DirectX 10 & 11 games aren't supported.
Radeon 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.
