In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3850 X2 are noticeably better than the AMD Radeon HD 6670 v2 MSI 2GB Edition.

The HD 6670 has a 131 MHz higher core clock speed than the HD 3850, but the HD 3850 has 8 more Texture Mapping Units than the HD 6670. As a result, the HD 3850 exhibits a 2.2 GTexel/s better Texture Fill Rate than the HD 6670. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 6670 has a 131 MHz higher core clock speed than the HD 3850, but the HD 3850 has 24 more Render Output Units than the HD 6670. As a result, the HD 3850 exhibits a 15 GPixel/s better Pixel Fill Rate than the HD 6670. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 6670 was released over three years more recently than the HD 3850, 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 3850 when running the latest games.

The HD 6670 has 1024 MB more video memory than the HD 3850, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the HD 3850 has superior memory performance.

The HD 3850 has 84.7 GB/sec greater memory bandwidth than the HD 6670, which means that the memory performance of the HD 3850 is much better than the HD 6670.

The Radeon HD 6670 v2 MSI 2GB Edition has 480 Shader Processing Units and the Radeon HD 3850 X2 has 640. However, the actual shader performance of the HD 6670 is 192 and the actual shader performance of the HD 3850 is 428. The HD 3850 having 236 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 3850 delivers a significantly smoother and more efficient experience when processing graphical data than the HD 6670.

The HD 6670 transistor size technology is 15 nm (nanometers) smaller than the HD 3850. This means that the HD 6670 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3850.

The Radeon HD 6670 v2 MSI 2GB Edition requires 66 Watts to run and the Radeon HD 3850 X2 requires 140 Watts. We would recommend a PSU with at least 400 Watts for the HD 6670 and a PSU with at least 450 Watts for the HD 3850. The HD 3850 requires 74 Watts more than the HD 6670 to run. The difference is significant enough that the HD 3850 may have an adverse affect on your yearly electricity bills in comparison to the HD 6670.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6670 v2 MSI 2GB Edition is a special edition of AMD's fast-middle-class Radeon HD 6670 v2, created by MSI.

Overclock: Central Unit
The Central Unit runs at the same speed.

Overclock: Memory Clock
The Operating Memory Clock runs at 667MHz and the Frame Buffer was raised to 2GB. This is a gimmick and in no way benefits the GPU.

Cooling Solution
The Cooling System remains the same.

Performance
Without Overclocking Out of The Box, Radeon HD 6670 v2 MSI 2GB Edition is as fast as the reference Radeon HD 6670 v2.
Radeon HD 3850 X2 (not Crossfire) is a dual-graphics solution of two Radeon HD 3850.
This combination is expected to offer almost the same performance as Radeon HD 3850 Crossfired while consuming slightly less power. However, and just like Crossfire, its performance also relies a lot on proper driver support.
Today's modern demanding games will have to be played using the medium preset but with fluent frame rates. However, DirectX 11 games aren't supported.
