In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7850 XFX Core Edition are massively better than the AMD Radeon HD 7660D + 6670 Dual.

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 less than a year after the HD 7850, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 7850 has 1024 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 7660D + 6670 Dual has 760 Shader Processing Units and the Radeon HD 7850 XFX Core Edition has 1024. However, the actual shader performance of the HD 7660D is 0 and the actual shader performance of the HD 7850 is 749. The HD 7850 having 749 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7850 delivers a massively smoother and more efficient experience when processing graphical data than the HD 7660D.

We would recommend a PSU with at least 500 Watts for the HD 7850, but we do not have a recommended PSU wattage for the HD 7660D.

GPU Mini Review

Mini ReviewRadeon 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.
Radeon HD 7850 XFX Core Edition is a special edition of the powerful Radeon HD 7850. See the standard version for more information about it.
This edition features a special cooling system that allows twice as much heat dissipation when compared to the reference AMD cooling system but its performance is still the same, as there's no over-clocking out of the box.
