To continuous streamlining of FinFET 14 nm production process, the latest Polaris GPUs that power SAPPHIRE NITRO+ Radeon RX 580 cards are even more energy-efficient. This allowed SAPPHIRE to crank up the clocks and reach up to 10% better performance compared to previous series. To add even more headroom for overclocking. Factory overclocked cores of the standard SAPPHIRE NITRO+ RX 580 run with a 1411 MHz boost clock. 4th generation Graphics Core Next GPUs of the Radeon RX 500 Series feature improved geometry engine, new display engine, increased caches and native asynchronous shaders. Equipped with 2304 GCN-based stream processors, the SAPPHIRE NITRO+ Radeon RX 580 is the card to run modern games in 1080p and beyond, as well as deliver premium VR experiences. Fuse protection In order to protect your card, the SAPPHIRE NITRO+ series cards have fuse protection built into the circuit of the external PCI-E power connector to keep the components safe. Precision fan control Standard industry fans may have up to 10% difference between their fan rotation cycles (RPM). With the new Fan IC Control on SAPPHIRE NITRO + graphics cards, this differential is reduced to 3%. This 70% improvement on accuracy ensures that cooling and noise performance of every NITRO + card is up to scratch. Robust VRM Cooling The SAPPHIRE NITRO+ cards are designed with robust VRM cooling and have a high thermal conductivity pad on the backplate to take away the heat efficiently and effectively.
