In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3800 series are marginally better than the Nvidia GeForce 8600 GTS 512MB.

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

The HD 3800 was released less than a year after the 8600 GTS, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 3800 series and the GeForce 8600 GTS 512MB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The 8600 GTS has 32 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the 8600 GTS is noticeably better than the HD 3800.

The Radeon HD 3800 series has 320 Shader Processing Units and the GeForce 8600 GTS 512MB has 32. However, the actual shader performance of the HD 3800 is 0 and the actual shader performance of the 8600 GTS is 54. The 8600 GTS having 54 better shader performance and an altogether better performance when taking into account other relevant data means that the 8600 GTS delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

The HD 3800 transistor size technology is 25 nm (nanometers) smaller than the 8600 GTS. This means that the HD 3800 is expected to run slightly cooler and achieve higher clock frequencies than the 8600 GTS. While they exhibit similar graphical performance, the HD 3800 should consume less power than the 8600 GTS.

The GeForce 8600 GTS 512MB requires 75 Watts to run but there is no entry for the HD 3800. We would recommend a PSU with at least 350 Watts for the 8600 GTS, but we do not have a recommended PSU wattage for the HD 3800.

GPU Mini Review

Mini ReviewRadeon 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.GeForce 8600 GTS is a fast-middle-class GFX based on the 80nm variant of the first-shader unified architecture.
It's based on the G84 Core and offers 32 Shader Processing Units, 16 TMUs and 8 ROPs, on a 128-bit memory interface of GDDR3. The central unit runs at 675MHz and the memory clock operates 1000MHz. It will consume no more than 75 Watt.
It's therefore a further clocked GeForce 8600 GT and should be significantly faster.
This GPU is only suited for a 1024x768 (or less) resolution. Today's games will run at medium settings although extremely demanding games might not run at all. DirectX 11 based games aren't supported and its performance will decrease drastically, as the resolution increases.
