Red Dragon 16 GB GDDR6 for 4K gaming

The PowerColor Radeon RX 6800 XT Red Dragon delivers 16 GB of GDDR6 memory on a PCIe 4.0 x16 interface. It targets enthusiasts who need high frame rates at 4K resolution in modern titles. The card occupies a 3-slot form factor and provides two DisplayPort 1.4 outputs plus one HDMI 2.1 port for multi-monitor setups.

Sustained load behaviour with 300 W TGP

A total graphics power of 300 W means the cooler must dissipate considerable heat during extended sessions. The base clock of 1.82 GHz and boost clock of 2.25 GHz are maintained by a fan and heatsink arrangement designed for continuous operation. VRAM runs at 2.00 GHz, keeping bandwidth stable when textures and buffers stay resident for long periods.

16 GB VRAM decides 8K texture capacity

The single specification that determines suitability is the 16 GB GDDR6 frame buffer. It enables 8K (4320p) maximum resolution and holds large texture pools without swapping. Buyers who need more video memory for heavy compute workloads or multi-GPU configurations cannot expand this card beyond its fixed 16 GB allocation.

Questions about this item

How much heat and power does the 300 W total graphics power generate during all-day use?

The card has a 300 W total graphics power rating, so a 750 W power supply is recommended. The Red Dragon cooler uses fans and a heatsink across a 3-slot design to move that heat out of the case.

Which power connectors and PSU capacity must my system already provide for this card to run?

A 750 W power supply is recommended to support the 300 W total graphics power. The board plugs into a PCIe 4.0 x16 slot and draws auxiliary power through standard 8-pin connectors.

Will the PCIe 4.0 x16 interface and 16 GB GDDR6 memory work properly on my older PCIe 3.0 motherboard?

Yes. The card fits a PCIe 4.0 x16 slot and is backward compatible with PCIe 3.0 motherboards. The 16 GB GDDR6 frame buffer and 2 x DisplayPort 1.4 plus 1 x HDMI 2.1 outputs function normally on the older platform.
