AMD’s upcoming RX 500 series of graphics cards is not going to challenge NVIDIA’s new GTX 1080 Ti, but it will replace the current-generation RX 400 series for mainstream gaming segment. AMD’s RX 500 series set to release on April 18th.
While the RX 500 series to use same Polaris architecture but AMD has made adjustments to improve performance and efficiency by taking advantage of manufacturing maturing and process improvements. The original Polaris 11 and Polaris 10 chips were manufactured using the Low Power Early (LPE) process, which looks to balance availability, yields, and time-to-market with performance and power. New reports peg the new dies to carry the Polaris 21 and Polaris 20 monikers and will feature higher clocks on account of the new Low Power Performance (LPP) process.
As to the higher clocks, these apparently are only responsible for bridging the gap between the RX 480’s reference and custom boards. The RX 580 will reportedly carry a 1340 MHz clock (74 MHz more than the reference RX 480), with the RX 570 taking a much less significant 38 MHz increase over its RX 470 counterpart. The Radeon RX 560 will come with a clock speed of 1287 MHz.
It will be integrating to see how AMD will deliver higher performance comparing to their previous-generation, using the same architecture. Though it is little disputing that AMD is not bringing Vega powered card for the mainstream market.
