Radeon HD 7700’s Specifications Surface

Following the successful launch of the Radeon HD 7970 and 7950, AMD has released some specifications of the new mid-range GPU solution that will be available to everyone sometime later this month. While performance wise these cards aren’t too impressive, they still are a sight to behold featuring new technology.

These cards use a better form of Graphics CoreNext stream processors, that are configured in a certain way to improve performance over last year cards slightly, while keeping the TDP (Total Draw Power) relatively low. I’m looking forward to these new AMD cards, even though they aren’t exactly groundbreaking.

These cards will be priced below $200, and expecting them to be workhorses is fool hardy. But, for those of you who are looking to upgrade you’re GPU, and your not playing PC games at 1920 x 1080 then these may be an option for you.  But, if you can wait at least another three months, you can see what NVidia has to offer.

The specifications for the cards are listed below along with the source.
