Sapphire Tech Toxic Radeon RX 6900 XT 11308-13-20G graphics card

Toxic Radeon RX 6900 XT identity

This Sapphire Tech Toxic Radeon RX 6900 XT is a refurbished graphics card built on the RDNA 2 architecture with 5120 stream processors. It targets enthusiasts who want high frame rates at 4K resolution and need 16GB of GDDR6 memory on a 256-bit bus. The PCI Express 4.0 interface keeps data moving between the GPU and the rest of the system.

Sustained load behaviour

An all-in-one liquid cooler with a 360 mm radiator moves heat away from the GPU during long gaming or compute sessions. The game clock runs at 2135 MHz while the boost clock can reach 2365 MHz when thermal headroom allows. A thermal design power below 400 W means the card draws significant power, so the system must supply at least 850 W.

Build and connectivity

The cooler uses an integrated pump and radiator assembly that occupies three 120 mm mounting positions in the case. Power arrives through two 8-pin and one 6-pin connectors. Display outputs comprise one HDMI 2.1 port and three DisplayPort 1.4 ports, supporting up to four monitors at a maximum resolution of 7680 x 4320.
