In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3650 are very slightly better than the Nvidia GeForce 6800 Ultra.

The Radeon HD 3650 was released over a year more recently than the GeForce 6800 Ultra, and so the Radeon HD 3650 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 6800 Ultra.

The Radeon HD 3650 and the GeForce 6800 Ultra have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce 6800 Ultra has 9.6 GB/sec greater memory bandwidth than the Radeon HD 3650, which means that the memory performance of the GeForce 6800 Ultra is marginally better than the Radeon HD 3650.

The Radeon HD 3650 has 120 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the Radeon HD 3650 is 87 and the actual shader performance of the GeForce 6800 Ultra is 9. The Radeon HD 3650 having 78 better shader performance is not particularly notable, as altogether the GeForce 6800 Ultra performs better when taking into account other relevant data.

The Radeon HD 3650 requires 65 Watts to run and the GeForce 6800 Ultra requires 124 Watts. We would recommend a PSU with at least 400 Watts for the Radeon HD 3650. The GeForce 6800 Ultra requires 59 Watts more than the Radeon HD 3650 to run. The difference is significant enough that the GeForce 6800 Ultra may have an adverse affect on your yearly electricity bills in comparison to the Radeon HD 3650.

GPU Mini Review

Mini ReviewRadeon HD 3650 is a fast-middle-class GPU based on the 55nm, second unified shader architecture, R600.
It's based on the RV635 PRO Core and offers 120 Shader Processing Units, 8 TMUs and 4 ROPs a 128-bit memory interface of standard GDDR3. The central unit runs at 725MHz and the memory clock runs at up to 800MHz.
Its performance is relatively below the average and so today's modern games will have to be played at modest resolutions from low to medium settings. DirectX 11 games aren't supported.
The groundbreaking new NVIDIA GeForce 6800 graphics processing units (GPUs) and their revolutionary technologies power worlds where reality and fantasy meet; worlds in which new standards are set for visual realism and quality, performance, and video functionality. The GeForce 6800 GPUs deliver powerful, elegant graphics to drench your senses, immersing you in unparalleled worlds of visual effects for the ultimate PC experience.
