In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3800 series are significantly better than the Nvidia GeForce GT 330.

The HD 3800 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The GeForce GT 330 was released over a year more recently than the HD 3800, and so the GeForce GT 330 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 3800.

The HD 3800 has 256 MB more video memory than the GeForce GT 330, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the HD 3800 also has superior memory performance overall.

The GeForce GT 330 has 16.3 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the GeForce GT 330 is slightly better than the HD 3800.

The GeForce GT 330 has 112 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the GeForce GT 330 is 140 and the actual shader performance of the HD 3800 is 0. The GeForce GT 330 having 140 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 330 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

The GeForce GT 330 requires 75 Watts to run but there is no entry for the Radeon HD 3800 series. We would recommend a PSU with at least 300 Watts for 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.
Radeon HD 3800 Series is not a GPU but instead a combination between Radeon HD 3830, Radeon HD 3850 and Radeon HD 3870 whose rank is a balance between the three and that exists for System Requirements purposes only.
