With the AMD Radeon R9 285 , AMD’s aim is simple – to ensure its product is cheaper, easier to produce, and more power-efficient. To cut a long story short, with its new ‘Tonga’ design it wants to get rid of the inefficiencies from the old Tahiti chip that powers the 280. Indeed, it also intends to transcend its Nvidia rival. The AMD Radeon R9 285 is AMD’s new $249 midrange enthusiast card.
