Today AMD launched a new generation of Radeon GPUs for graphics cards, called the Radeon RX 500 series. The new Radeon RX 580, RX 570, RX 560 and RX 550 are based on a revision of the Polaris architecture which powered last year's Radeon RX 400 series.The new Radeon RX 500 series is aimed at gamers who want to upgrade from graphics cards that are at least two years old and do not support VR or the latest game development standards such as DirectX 12 and Vulkan. AMD promises that the new products' higher clock speeds, reduced latency and improved software will help gamers play current-day titles such as Battlefield 1, COD: Infinite Warfare and Resident Evil: Biohazard without compromising on resolution or image quality.
Radeon RX 580 is the most powerful GPU of the lot, superseding the RX 480. It is aimed at gamers who want a smooth 60fps at 1440p with the settings turned up high. It has 36 "compute unit" processing clusters and base/boost clock speeds of 1257/1340MHz respectively. All Radeon RX 580 graphics cards will have either 4GB or 8GB of GDDR5 RAM on a 256-bit interface, similar to Radeon RX 480 cards. AMD claims that users can expect 57 percent better performance compared to that of a Radeon R9 370. AMD's recommended prices are $229 (approximately Rs. 14,800) for 8GB cards and $199 (approximately Rs. 12,850) for 4GB cards.the Radeon RX 560 replaces the RX 460. It will target budget-conscious users who will play e-sports games at 1080p and who won't expect to run the latest AAA titles at full settings. Buyers will get a modest 16 compute units and base/boost speeds of 1175/1275MHz respectively. Cards will have 4GB of GDDR5 RAM on a narrower 128-bit bus. Performance is said to exceed that of a two-year-old Radeon R7 360 by up to 57 percent. Prices will start at $99
GPUs support HEVC H.265 4K video decoding. AMD also touts its Freesync technology which allows monitors and graphics cards to synchronise their refresh cycles to avoid frame tearing, and Radeon Chill, which can regulate power consumption depending on the intensity of different scenes in a game.
