In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6690D2 are noticeably better than the AMD Radeon HD 3800 series.

Neither GPUs' core clock speed has been set, and so any comparison between Texture and Pixel Fill Rates is not currently possible. The has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The HD 3800 was released over three years more recently than the Radeon HD 6690D2, and so the HD 3800 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon HD 6690D2 when running the latest games.

The HD 3800 has 512 MB video memory, but the Radeon HD 6690D2 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon HD 6690D2 has 0 Shader Processing Units and the Radeon HD 3800 series has 320. The two GPUs are based on different architectures, but deliver an equivalent shader performance. To compare, we must continue to look at the memory bandwidth, Texture and Pixel Rates. In this case, we sadly do not have enough data in this area to complete the comparison.

GPU Mini Review

Mini ReviewRadeon HD 6690D2 is a combination of a Radeon 6550D (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 the performance should be around 7% better than a Radeon HD 6670 performing by itself but in some cases it might be worse.
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.
