In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6670 v2 Gigabyte 1GB 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 6670 was released over three years more recently than the HD 3800, and so the HD 6670 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 3800 when running the latest games.

The HD 6670 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 6670 also has superior memory performance overall.

The HD 6670 has 25.6 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the HD 6670 is slightly better than the HD 3800.

The Radeon HD 6670 v2 Gigabyte 1GB Edition has 480 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the HD 6670 is 192 and the actual shader performance of the HD 3800 is 0. The HD 6670 having 192 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 6670 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

The HD 6670 transistor size technology is 15 nm (nanometers) smaller than the HD 3800. This means that the HD 6670 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3800.

The Radeon HD 6670 v2 Gigabyte 1GB Edition requires 66 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 6670.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6670 v2 Gigabyte 1GB Edition is a special edition of AMD's fast-middle-class Radeon HD 6670 v2, created by Gigabyte.

Overclock Out of The Box
The Clock Frequencies of both Central Unit and Operating Memory Clock Remain the Same.

Cooling Solution
The Cooling System has Gigabyte's custom-designed 10cm cooler.

Performance
Without Overclocking Out of The Box, Radeon HD 6670 v2 Gigabyte 1GB Edition is as fast as the reference Radeon HD 6670 v2.
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.
