Even though there are numerous graphics cards based on ATI RV770 graphics processing units available, Advanced Micro Devices has so far been reluctant to utilize more advanced ATI RV790 graphics chip to power non-ATI Radeon HD 4890 graphics cards. Nevertheless, according to unofficial information, the company will use the chip for its model 4860.
According to it168.com web-site, ATI, graphics business unit of AMD, is preparing ATI Radeon HD 4860 graphics card that will feature cut-down version of the RV790 chip (so-called RV790 GT) with 640 stream processing units clocked at 700MHz or 7500MHz as well as with 512MB 3000MHz GDDR5 memory. The board will still offer HDMI output and other advantages of the RV790, such as overclockability, but will consume less energy and will require less advanced power supply units.
ATI Radeon HD 4860 has all chances to offer performance very close to that of the model 4870 and easily exceed that of the model 4850.
Since the information comes from a China-based web-site, the Radeon HD 4860 may end up as a product aimed only at the local market. Nevertheless, potentially, the Radeon HD 4860 has all the chances to become a rather popular option in the $100 - $129 price-segment in Europe or the U.S. due to its indisputable advantages over the Radeon HD 4850 that currently retails for around $100. Currently it is expected that the Radeon HD 4860 will cost approximately $116 - $133 in local currency (799 – 899 Chinese Yuan).
ATI did not comment on the news-story.
