The latest addition to AMD's Radeon HD 4000 series (R700) family is the ATI Radeon HD 4770 graphics card, which was released in late April. We finally have our hands on this graphics card which uses the RV740 -- the first 40nm GPU -- and have proceeded to run our usual assortment of Linux-based tests. Along with the transition from a 55nm to 40nm process, the Radeon HD 4770 has been designed to bridge the current R700 solutions to their next-generation graphics processors that will be introduced later this year. The Sapphire Radeon HD 4770 may cost less than $100 USD, but it packs serious performance capabilities.
