AMD has introduced a refreshed model of RX480; the RX 580 which is here to compete with high-end Nvidia cards such as GTX 1080 Ti, GTX 1080 and GTX 1070. AMD RX 580 uses the company’s Polaris architecture with slight improvements and better clock speeds.
The AMD RX 580 packs either 4GB or 8GB GDDR5 RAM on a 256-bit interface with the same 2,304 stream processors and is again based on the Polaris architecture which uses 14nm FinFET manufacturing process. The RX 580 has a core clock speed of 1,257MHZ and a boost clock of 1,340MHz aiming a smooth 60fps at 1440p with highest graphic settings. Which is quite faster than its previous generation; the RX 480. Though the new RX 500 series graphic cards is not based on the all-new Vega architecture, the Polaris Architecture is equally powerful.
The RX 580 supports HEVC H.265 4K video decoding and comes with Freesync technology which basically allows monitors and graphic cards synchronize their refresh cycles to avoid frame drops. The Radeon Chill regulates power consumption depending on the intensity of the scenes in the game that you are playing.
Price and Availability: The Radeon RX 580 will be available immediately on board with partners like Sapphire, Asus, PowerColor, Gigabyte, and MSI. The 8GB variant is priced at $229 (approx Rs. 14,800) and $199 (approx Rs. 12,850) for 4GB card.
