The silicon also has a number of architectural changes. Together with clock speeds, RDNA is designed to bring about massive IPC improvements over GCN. These constitute the biggest update to AMD's GPU design since the very first Graphics Core Next (GCN) architecture circa 2013. It's based on the brand new "Navi" architecture that leverages the 7 nm silicon fabrication process and has brand new number-crunching machinery AMD calls RDNA compute units. The Radeon RX 5700 XT is AMD's first true performance-segment graphics card in over two years since the RX Vega series. Sapphire is pricing the card at $480, which is a $30 increase over the RX 5700 XT Nitro+. Besides the higher clock frequencies, Sapphire is including their $30 ARGB fan kit pre-installed with the card, which makes for an impressive RGB light show. This makes the Nitro+ Special Edition the fastest air-cooled Radeon RX 5700 XT on the market. Positioned above the RX 5700 XT Nitro+, the Special Edition adds better aesthetics and higher factory-overclocked speeds out of the box, including overclocked memory. Just a few days ago, Sapphire released the Radeon RX 5700 XT Nitro+ Special Edition, a premium variant that crowns the company's RX 5700-series "Navi" family of graphics cards.
