In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 330 are noticeably better than the Nvidia GeForce 6800 Ultra.

The GeForce GT 330 was released over three years more recently than the GeForce 6800 Ultra, and so the GeForce GT 330 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 6800 Ultra when running the latest games.

The GeForce GT 330 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 18.9 GB/sec greater memory bandwidth than the GeForce GT 330, which means that the memory performance of the GeForce 6800 Ultra is slightly better than the GeForce GT 330.

The GeForce GT 330 has 112 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the GeForce GT 330 is 140 and the actual shader performance of the GeForce 6800 Ultra is 9. The GeForce GT 330 having 131 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 330 delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6800 Ultra.

The GeForce GT 330 requires 75 Watts to run and the GeForce 6800 Ultra requires 124 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 330. The GeForce 6800 Ultra requires 49 Watts more than the GeForce GT 330 to run. The difference is significant enough that the GeForce 6800 Ultra may have a slight adverse affect on your yearly electricity bills in comparison to the GeForce GT 330.

GPU Mini Review

Mini ReviewGeForce GT 330 is a middle-class GFX based on the 2009, 65nm, first-generation unified architecture.
It's based on the G92b Core and offers 112 Shader Processing Units, 56 TMUs and 16 ROPs, on a 128-bit memory interface of standard DDR2. The central unit runs at 500MHz and the memory clock operates at up to 510MHz.
The number of Shaders cannot be compared to GeForce GT 340 due to being based on a different architecture. It's therefore an underclocked GeForce 8800/9800 GT, equipped with a 128-bit bus and that should perform like GeForce 9600 GSO.
Today's modern demanding games will have to be played at medium settings to achieve fluent frame rates. 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.
