Hey guys,
I got my new laptop today and it says that I have 2 graphic cards Radeon HD 7640G + 7670M 1GB.
Are dual graphic cards better then one or...? What is it good for?
It's not two graphics cards. The 7640g is the Integrated Graphics Processor (IGP) of a Amd Trinity chip, in your case the A8-4500m. The 7670m is a dedicated card with GDDR3 memory. In theory they can run in hybrid crossfire (dual graphics) and you will get a speed boost. To put it more plainly, notebookcheck has the 7660g+7670m (A10-4600m processor and dedicated 7670m) rated at only 1% below a GT 650m, however, that's if the application (game usually) supports the dual graphics. Currently there are not enough titles that properly support it so you usually have to make a profile under catalyst to specify the use of the 7670m. Over the next year though, as drivers mature for trinity dual graphics, and more games begin to take advantage of it, then it should become a hot topic for low budget gamers.
