In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3850 are significantly better than the Nvidia GeForce 8600 GT 512MB GDDR3.

The Radeon HD 3850 has a 128 MHz higher core clock speed and the same number of Texture Mapping Units as the 8600 GT. This results in the Radeon HD 3850 providing 2.1 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 Radeon HD 3850 has a 128 MHz higher core clock speed and 8 more Render Output Units than the 8600 GT. This results in the Radeon HD 3850 providing 6.4 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 Radeon 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 8600 GT has 256 MB more video memory than the Radeon HD 3850, so is likely to be slightly better at displaying game textures at higher resolutions. However, overall, the Radeon HD 3850 has superior memory performance.

The Radeon HD 3850 has 30.7 GB/sec greater memory bandwidth than the 8600 GT, which means that the memory performance of the Radeon HD 3850 is noticeably better than the 8600 GT.

The GeForce 8600 GT 512MB GDDR3 has 32 Shader Processing Units and the Radeon HD 3850 has 320. However, the actual shader performance of the 8600 GT is 43 and the actual shader performance of the Radeon HD 3850 is 214. The Radeon HD 3850 having 171 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 3850 delivers a noticeably smoother and more efficient experience when processing graphical data than the 8600 GT.

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

The GeForce 8600 GT 512MB GDDR3 requires 46 Watts to run and the Radeon HD 3850 requires 75 Watts. We would recommend a PSU with at least 350 Watts for the 8600 GT and a PSU with at least 450 Watts for the Radeon HD 3850. The Radeon HD 3850 requires 29 Watts more than the 8600 GT to run. The difference is not significant enough for the Radeon HD 3850 to have a noticeably larger impact on your yearly electricity bills than the 8600 GT.

GPU Mini Review

Mini ReviewGeForce 8600 GT 512MB GDDR3 is one of the many variants of the fast-middle-class GeForce 8600 GT.
On this version, the GPU is equipped with 512MB of standard GDDR3. The architecture allows the use of 512MB, since the GPU's processing power is strong enough and the memory controller is up for the task of processing 512MB. Therefore, the performance is superior to the 256MB version and any other version of DDR2, including 1GB.
However, and due to its architecture limitations, modern demanding games will require reduced settings, even if they don't require more than 512MB of video ram. Very Demanding games like Metro 2033 are only playable at the lowest settings.
Radeon HD 3850 is a high-end GPU based on the 55nm, second unified shader architecture, R600.
It's based on the RV670 PRO Core and offers 320 Shader Processing Units, 16 TMUs and 16 ROPs a 256-bit memory interface of standard GDDR3. The central unit runs at 668MHz and the memory clock runs at up to 830MHz.
It offers much better performance when compared to Radeon HD 3650, thanks to the extra Shaders and does not consume much more power.
Today's modern games should run fluently at medium settings but with modest resolutions only. DirectX 11 games aren't supported.
