TUM APISAK discovered new entries of yet unannounced Radeon RX 590 graphics card. AMD Radeon RX 590: Polaris strikes back? What is Radeon RX 590? Well, no one really knows. Rumors about a 'new' Radeon card started appearing last week (actually they started appearing a few months ago, but it was hard to believe at the time -- still is). What is believed now, however, is that Radeon RX 590 would feature Polaris architecture, except on 12nm the fabrication node. This would improve performance and power efficiency, but it would certainly not provide a proper response to NVIDIA's Turing.
