In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3850 AGP are significantly better than the Nvidia GeForce 8600 GT 256MB DDR3 Fatal1ty Edition.

The HD 3850 has a 28 MHz higher core clock speed and the same number of Texture Mapping Units as the 8600 GT. This results in the HD 3850 providing 0.5 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 3850 has a 28 MHz higher core clock speed and 8 more Render Output Units than the 8600 GT. This results in the HD 3850 providing 5.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 3850 was released less than a year after the 8600 GT, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 3850 has 256 MB more video memory than the 8600 GT, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the HD 3850 also has superior memory performance overall.

The HD 3850 has 25.9 GB/sec greater memory bandwidth than the 8600 GT, which means that the memory performance of the HD 3850 is slightly better than the 8600 GT.

The GeForce 8600 GT 256MB DDR3 Fatal1ty Edition has 32 Shader Processing Units and the Radeon HD 3850 AGP has 320. However, the actual shader performance of the 8600 GT is 51 and the actual shader performance of the HD 3850 is 214. The HD 3850 having 163 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 3850 delivers a noticeably smoother and more efficient experience when processing graphical data than the 8600 GT.

The HD 3850 transistor size technology is 25 nm (nanometers) smaller than the 8600 GT. This means that the HD 3850 is expected to run slightly cooler and achieve higher clock frequencies than the 8600 GT.

The Radeon HD 3850 AGP requires 75 Watts to run but there is no entry for the 8600 GT. We would recommend a PSU with at least 300 Watts for the 8600 GT and a PSU with at least 450 Watts for the HD 3850. The HD 3850 has been recommended a PSU with 150 Watts more than the 8600 GT. The difference is significant enough that the HD 3850 may have an adverse affect on your yearly electricity bills in comparison to the 8600 GT.

GPU Mini Review

Mini ReviewGeForce 8600 GT 256MB DDR3 Fatal1ty Edition is a special edition of the GeForce 8600 GT. See the standard page for more information about it.
The new features include increases in the core and memory clocks that went from 540MHz to 640MHz and from 700MHz to 850MHz, respectively.
Benchmarks indicate a 5% performance boost when compared to the standard edition.
Radeon HD 3850 AGP is a variant of the high-end Radeon HD 3850 based on the 55nm, second unified shader architecture, R600. Check its page to know more about its Core.
Compared to Radeon HD 3850, it features twice as much video memory and an AGP 8X Bus Interface. Benchmarks indicate the double sized frame buffer benefits this GPU largely and so its performance is up to 8% better than the reference Radeon HD 3850.
Today's modern games should run fluently at medium settings but with modest resolutions. DirectX 11 games aren't supported.
