ATI, graphics business unit of Advanced Micro Devices, on Tuesday unveiled the industry’s first mainstream graphics processing units (GPUs) that support DirectX 11 application programming interface. The new chips offer higher performance compared to predecessors and their improved functionality is more than likely to make them popular among mass buyers.


The new ATI Radeon HD 5700-series (which currently consists of models 5750 and 5770) is based on the code-named Juniper graphics processor that is made using 40nm process technology and consists of 1.04 billion of transistors. Both chips feature 128-bit memory bus and can boast with support of DirectX 11, OpenGL 3.2, hardware-accelerated HD video decoding and post-processing, ATI Eyefinity technology that allows to plug up to five standard-resolution displays to a single graphics card (provided that there is enough connectors) or up to three monitors with 2560x1600 resolution as well as ATI’s latest technologies that trim power consumption and so on.

ATI Radeon HD 5770 operates at 850MHz, features 800 stream processing units, 40 texture units, 16 render back ends and uses 4.8GHz GDDR5 memory. ATI Radeon HD 5770 functions at 700MHz, features 720 stream processing units, 36 texture units, 16 render back ends and utilizes 4.6GHz GDDR5 memory.

At present AMD’s Radeon HD 5700-series is the only family of DX11 chips for the mainstream market. Even though there are no video games that rely on the new API, customers, who buy mainstream graphics boards usually keep them for about 1.5 years, therefore, for them, DirectX 11 is an important future-proof feature.

Add-in card manufacturers will sell ATI Radeon HD 5770 for about $159, whereas different versions of the model HD 5750 will be available from $109 to $129. Select graphics cards will come bundled with a special coupon, which will allow its owners to get Dirt 2 game for free.
