The video card radeon HD 4890 with atomic suffix from sapphire production became the first prototypes, which reached the core frequency 1 GHz. Yesterday the video card sapphire radeon HD 4890 Atomic was presented officially.
Reaching the default frequencies 1000/4200 MHz was possible not only due to the cooling system vapor- X with vaporizing chamber technology, but also due to an increase in the core voltage from 1.3 v to 1.5 v..
This video card will be supplied in a special case. This card will cost additional $50 in comparison with the standard version radeon HD 4890.
This is not the last version radeon HD 4890 from Sapphire - new modifications will be released soon. Related Products :
