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.

What to say but, it has been expected. They need to clean up wasted chips from their inventory and what's better way than to sell them as some GT product based on old chip cause when they actually release it will overlap for quite some time with their Cypress family (dx11 chips).

And for that premium price it's better to buy RV740 based card if TSMC ever mass produce these chips no matter how good news on their old farth 40nm process are. It costs less and consumes more than twice less.

RV790 based graphics that will consume less energy? You must be joking, RV790 at same speeds as RV770 consumes up to 20% more energy. And it will be a real surprise to see some budget mainstream card (129USD) that consumes 120W+ when it came up with some poor cooler like most of hd4850 did (even when they cost over 219USD). What the hell, we dont even see RV740 based cards that are cheaper to produce than this hyper hd4860 (chip, PSU, PCB) with their original-just for showcasing cooler but with some noisy 80mm slim fans attached on chunk of extruded aluminum that suppose to be a cooler.
