When AMD launched the Polaris-based Radeon RX 480 in June 2016, the focus was firmly on the mainstream market, looking to offer superior value over raw performance. At the same time, AMD also sought to improve power efficiency by leveraging both microarchitectural changes and their first generation of FinFET GPUs. Ultimately, this straightforward approach was somewhat derailed by the recent cryptocurrency mining craze, but Polaris has carried on, appearing in consoles (Xbox One X and PS4 Pro) as well as an early 2017 refresh in the form of the Radeon RX 500 series. Launching today is the latest entry with new top offering in the RX 500 series: the AMD Radeon RX 590.
