AMD Radeon RX 580 And RX 570 Mainstream GPU Reviews: High Performance Polaris

In preparation for the impending launch of AMD's next-generation Vega GPU architecture, which will eventually reside at the top of the company's graphics product stack, AMD is refreshing its mainstream graphics card line-up with some more-powerful Polaris-based offerings. In time, the new Radeon RX 580, RX 570, RX 560, and RX 550 cards launching today will supplant all of the current-generation Radeon RX 400-series cards, though these new cards are not radically different from their predecessors. Their clocks, shader counts, and memory configurations have been tweaked, but they’re still based on the same Polaris architecture and offer similar feature sets.
