The Card

XFX is reusing their design philosophy from the Radeon RX 6000 Series. The main color theme is black with metallic highlights. I have to say I really like the sleek looks of the card, and the matte metal surface. Both the main cooler shroud and backplate are made from thick metal.


The XFX logo on the right side of the card is ARGB illuminated.

Graphics Card Dimensions

Dimensions of the card are 34.0 x 13.5 cm, and it weighs 1767 g.

Installation requires three slots in your system.

Monitor Outputs, Display Connectors

Display connectivity includes three standard DisplayPort 2.1 ports (RDNA 2 had 1.4a) and one HDMI 2.1a (same as RDNA 2).

AMD has upgraded their encode/decode setup. It now comes with two independent hardware units that can encode and decode two streams of video in parallel, or one stream at double the FPS rate. There's support for VP9, H.264, H.265 and AV1 decode, and encoding is supported for H.264, H.265 and AV1.

Graphics Card Power Plugs

The card uses a classic triple 8-pin power input config, rated for 525 W maximum power. NVIDIA on the other hand uses the new 12+4 pin ATX 12VHPWR connector, which is rated for up to 600 W of power draw.


This dual BIOS switch lets you toggle between the default BIOS and "Full Power" BIOS, which increases the power limit from 327 W to 339 W. Given a 525 W power delivery capability I'm not sure if that really can be called "Full Power." The clock speeds are increased accordingly, to 2680 MHz Boost, up from 2615 MHz.

The main heatsink provides cooling for the GPU chip, memory chips and VRM circuitry. A vapor-chamber baseplate soaks up heat from the GPU chip and eight heatpipes move it to the surrounding heatsink fins.


The backplate is made from thick metal and of excellent build quality. It protects the card against damage during installation and handling.
