AMD officially reveals their RX 5700 family of Navi graphics cards
AMD has announced two new graphics cards, the RX 5700 XT and the RX 5700, both of which utilise AMD’s new Navi graphics core which offers increased GPU IPC, to deliver up to 25% more performance per clock, and higher clock speed to deliver compelling performance levels at an affordable price.Â
The RX 5700 XT targets Nvidia’s RTX 2070 graphics card with a price tag of $449 while the RX 5700 targets the RTX 2060 for $379. With the RX 5700 XT, AMD estimates a -1% to +22% performance difference when compared the RTX 2070 at 1440p, while the RX 5700 offers a +2 to +21% performance differential at the same resolution.Â
Below are the specifications of AMD’s new RX 5700 series graphics cards when compared to AMD’s existing offerings. Please note that AMD’s Navi architecture offers a 25% IPC boost over AMD’s existing offerings, so raw TFLOPS VS TFLOPS comparisons are not useful for performance comparisons.Â

AMD’s new RX 5700 series cooler utilises a standard air blower cooler, similar to Radeon’s older reference designs. The graphics card will utilise a 7-phase power solution and offer an 8+6-pin power setup. With this generation, AMD utilises a vapour chamber and a blower fan to keep Navi cool and, hopefully, quiet, even while overclocked.Â
Navi is said to offer a 1.5x increase in performance per watt over AMD’s last-generation product offerings, which means that Navi should be cool running when compared to Vega. Hopefully, this means that AMD’s reference cooler will keep Navi cool and quiet under load.Â
