In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 5670 1GB DDR3 Sapphire Edition are noticeably better than the AMD Radeon HD 3800 series.

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

The HD 5670 was released over a year more recently than the HD 3800, and so the HD 5670 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 5670 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 HD 5670 also has superior memory performance overall.

The HD 5670 has 25.6 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the HD 5670 is slightly better than the HD 3800.

The Radeon HD 5670 1GB DDR3 Sapphire Edition has 400 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the HD 5670 is 202 and the actual shader performance of the HD 3800 is 0. The HD 5670 having 202 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 5670 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

The HD 5670 transistor size technology is 15 nm (nanometers) smaller than the HD 3800. This means that the HD 5670 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3800.

The Radeon HD 5670 1GB DDR3 Sapphire Edition requires 64 Watts to run but there is no entry for the Radeon HD 3800 series. We would recommend a PSU with at least 400 Watts for the HD 5670.

GPU Mini Review

Mini ReviewRadeon HD 5670 1GB DDR3 Sapphire Edition is a special edition of the fast-middle-class Radeon HD 5670 which is part of the Radeon HD 5000 Series released by AMD in 2009/2008.
We did not identify any OC or relevant features and so the performance should be exactly like the standard Radeon HD 5670 equipped with DDR3.
Therefore, modern demanding games like Skyrim V can be played smoothly at high settings but not paired with image improving techniques, such as AA and Tesselation.
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.
