The Radeon Pro W6900X MPX Module is based on AMD's high-end Navi 21 workstation graphics chip that was fabricated on the 7 nm process. The GPU base clock speed was 1.825 GHz, which could be boosted to 2.15 GHz, producing up to 22.2 teraflops. It contained 32 GB of GDDR6 video RAM, running at 2 GHz.AMD Radeon Pro W6900X, TechPowerUp GPU Database. Accessed 2022-05-05. It features one HDMI 2.0/2.1 port and four USB-C compatible Thunderbolt 3 ports. It could support three 5K or 6K displays, or six 4K displays. The first Thunderbolt 3 port and the HDMI port shared a PCIe lane, reducing the output of that Thunderbolt 3 port if the HDMI port was used. The MPX module took up the space of two double-wide PCIe cards, but did not require an auxiliary power cable as it could draw all necessary power from the proprietary MPX connector.
