In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7660D 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 Radeon HD 7660D was released over three years more recently than the HD 3800, and so the Radeon HD 7660D 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 3800 has 512 MB video memory, but the Radeon HD 7660D does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon HD 7660D has 380 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the Radeon HD 7660D is 198 and the actual shader performance of the HD 3800 is 0. The Radeon HD 7660D having 198 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 7660D delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

GPU Mini Review

Mini ReviewRadeon HD 7660D is an embedded GPU on the high-end Trinity CPUs A10-5700 and A10-5800K.
Since the GPU doesn't have dedicated memory, the bandwidth will depend on the system ram speed which can be up to 1866MHz (the max speed supported by the CPU). Therefore, the max memory speed is 933MHz.
Its core-clock is clocked at 760MHz, if embedded on A10-5700 and 800MHz, if embedded on A10-5800K, and comes with 384 Shader Processing Units.
Radeon 7660D's performance depends a lot on driver support and embedded CPU and varies from game to game in a way games in the same category (demanding, very demanding, etc) can be unplayable at the lowest settings or might run at medium/high settings.
Please note this GPU's rank is a weighted average between the two available versions.
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.
