In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3800 series are significantly better than the Nvidia GeForce GT 320.

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 320 was released over a year more recently than the HD 3800, and so the GeForce GT 320 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 GeForce GT 320 has 512 MB more video memory than the HD 3800, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GT 320 also has superior memory performance overall.

The GeForce GT 320 has 25.3 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the GeForce GT 320 is slightly better than the HD 3800.

The GeForce GT 320 has 72 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the GeForce GT 320 is 89 and the actual shader performance of the HD 3800 is 0. The GeForce GT 320 having 89 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 320 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

The GeForce GT 320 transistor size technology is 15 nm (nanometers) smaller than the HD 3800. This means that the GeForce GT 320 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3800.

The GeForce GT 320 requires 43 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 320.

GPU Mini Review

Mini ReviewGeForce GT 320 is an entry-level GFX based on the 2009, 40nm, second-generation unified architecture.
It's based on the GT215 Core and offers 72 Shader Processing Units, 24 TMUs and 8 ROPs, on a 128-bit memory interface of standard GDDR3. The central unit runs at 540MHz and the memory clock operates at up to 790MHz.
Its performance lies around GeForce GT 230.
Today's modern demanding games will have to be played at low (most) or medium (some) 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.
