AMD Intros $99 DirectX 11 Graphics Card

 

AMD's latest graphics cards provide the horsepower needed to play mainstream video games. The Radeon HD 5670 includes AMD's ATI Eyefinity technology, which supports up to three displays, providing at least one has a DisplayPort connector.

 

In addition to bringing the full DirectX 11, OpenCL, and DirectX Compute features found in all the other 5000 series ATI cards, the 5670 still includes support for "Eyefinity", ATI's multiple monitor solution. Clock speeds are 775 MHz for the graphics core, with 1 GHz GDDR5 memory on a 128-bit bus. That gives it a peak of 620 gigaflops of compute power and 64 GB/sec of memory bandwidth. Perhaps its best feature is power consumption (or lack thereof). ATI says the card shouldn't use more than 61 watts under full load. There are a lot of systems out there with weak power supplies meant for integrated graphics - they don't supply more than the required 75W to the PCIe bus and they don't have dedicated plugs for PCIe graphics cards. The low power draw of this card means it can easily go in these systems.

 

Performance should be pretty good for a card debuting at the $100 mark. A Radeon HD 4770 would cost roughly the same, and for that matter you can even find some Radeon HD 4850 cards just barely above the $100 mark. Either of these would be faster (the 4850 would be much faster), but both require far more power than the 5670 and neither one provides DirectX 11 support.

 

 

AMD has shiped more than 2 million DirectX 11 graphics cards, according to the vendor. Pricing for the Radeon HD 5670 starts at $99 for 512 MB of GDDR5 memory.
