Toxic Radeon RX 6900 XT 16GB

This Sapphire Tech Toxic Radeon RX 6900 XT graphics card delivers 16GB of GDDR6 memory across a 256-Bit interface for enthusiasts and creators targeting 4K gaming and compute workloads. The PCI Express 4.0 board carries 5120 stream processors and supports DirectX 12 Ultimate on Windows 10, Windows 11 and Linux platforms.

Sustained load behaviour

An integrated AIO liquid cooling system manages the thermal design power of under 400W, allowing the GPU to hold its 2365 MHz boost clock and 2135 MHz game clock during extended sessions. The 16 Gbps effective memory clock remains stable while the three 8-pin and one 6-pin power connectors feed the board from an 850W supply.

Build quality and connectivity

The factory-fitted liquid cooler removes the need for bulky air heatsinks, easing installation in mid-tower cases with standard PCIe x16 spacing. One HDMI 2.1 port and three DisplayPort 1.4 outputs drive up to four displays at 7680 x 4320 resolution for surround gaming or multi-monitor productivity.

Questions about this item

How much heat and power does the 400 W Toxic Radeon RX 6900 XT produce when running all day?

The card has a Thermal Design Power below 400 W and uses an AIO liquid cooler to move that heat out of the case efficiently.

Which power connectors and PSU capacity must I already have for this 11308-06-20G to work?

You need a minimum 850 W power supply with two 8-pin and one 6-pin PCIe connectors free.

Will the PCI Express 4.0 Toxic Radeon RX 6900 XT run at full speed in my older PCIe 3.0 motherboard slot?

Yes, the card is backward compatible and will operate in a PCIe 3.0 x16 slot with only a small bandwidth reduction.
