In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7660D + 6670 Dual are very slightly better than the AMD Radeon HD 6670 v2 MSI 2GB Edition.

The HD 7660D has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The HD 7660D was released over a year more recently than the HD 6670, and so the HD 7660D is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6670.

The HD 6670 has 2048 MB video memory, but the HD 7660D does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon HD 6670 v2 MSI 2GB Edition has 480 Shader Processing Units and the Radeon HD 7660D + 6670 Dual has 760. However, the actual shader performance of the HD 6670 is 192 and the actual shader performance of the HD 7660D 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 marginally smoother and more efficient experience when processing graphical data than the HD 7660D.

The Radeon HD 6670 v2 MSI 2GB Edition requires 66 Watts to run but there is no entry for the Radeon HD 7660D + 6670 Dual. We would recommend a PSU with at least 400 Watts for 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 7660D + 6670 Dual is a combination of a Radeon 7660D (integrated graphics) with a Radeon HD 6670 (dedicated).
This combination is called Asymmetric CrossFire and can also lead to Micro Stuttering.
We do not know much about this GPU at the moment but it appears to be 4% worse than a single Radeon HD 6670 performing by itself but in some cases it might be worse or better.
