AMD has a new range of graphics cards in the form the RX 580, RX 570, RX 560, and RX 550.

All, bar the new RX 550, are slightly tweaked versions of the 400-series that debuted with RX 480 in June and feature the company’s 14nm Polaris architecture.
The RX 580 and RX 570 launch today at an MSRP of £185 and £165 for a 4GB version (8GB will also be available).

The 2GB RX 560 launches in early May for £99, while the 2GB RX 550 launches on April 20 for a wallet-friendly £80.

While some might call the 500-series a rebrand, AMD says an improved 14nm FinFET manufacturing process has helped it push up clock speeds.

The reference design RX 580, which features the same core specs as the RX 480 including 36 compute cores and a 256-bit memory interface, is clocked at 1257MHz and boosts to 1340MHz.

That’s just over 100MHz higher than the RX 480.
