FOLLOW UP: PowerColor Does Not Manufacture ATI Radeon HD 4770 – Company.
PowerColor, a popular graphics cards brand owned by Tul Corp., has quietly released ATI Radeon HD 4770 graphics card for rather outdated Accelerated Graphics Port bus. The new graphics board has his chances to become a demanded product by owners of old systems wishing to use them for modern video games and high-definition video playback.
ATI Radeon HD 4770, which is powered by ATI RV740 graphics processing units (GPUs), features 640 stream processors, 32 texture units, 16 render back ends and 128-bit GDDR3/GDDR4/GDDR5 memory controller. ATI, graphics business of Advanced Micro Devices, recommends its partners among graphics cards makers to clock the chip at 750MHz and install 512MB of GDDR5 memory at 3200MHz.
Accelerated Graphics Port bus is present on out-of-date systems that typically feature outdated microprocessors and other components. Nevertheless, many users of such systems want to playback high-definition GPU-accelerated video as well as, at least, try out modern video games. As a result, the demand for graphics cards with AGP interface that support DirectX 10.1 application programming interface, hardware acceleration of high-definition video playback and other modern functions still exists.
Since ATI Radeon HD 4770 chip does not feature native AGP support and PowerColor uses a special bridge chip to enable support of AGP interface, end-users have to ensure that the card is actually compatible with their mainboards and systems.
Powercolor 1A1-G000004992 ATI Radeon HD 4770 512MB GDDR5 AGP graphics card is available from various stores, including Amazon.com for $99.
