PowerColor Red Dragon Radeon RX 6800 XT

This graphics card uses the AMD RDNA 2 architecture with 4608 stream processors and 16GB of GDDR6 memory on a 256-bit interface. It targets enthusiasts who want high frame rates at 1440p or entry-level 4K gaming. The factory overclock pushes the boost clock up to 2310 MHz in OC mode.

PCI Express 4.0 interface limits

The card connects through a PCI Express 4.0 x16 slot, which provides the full bandwidth needed for the 16.0 Gbps memory speed. On a PCI Express 3.0 platform the link runs at half that throughput, which can reduce performance in bandwidth-heavy titles. A motherboard with PCI Express 4.0 support is required to realise the specified speeds.

300W board power and dual 8-pin connectors

The board draws up to 300W and requires two 8-pin power connectors from the supply. The manufacturer states a minimum system power requirement of 750W and recommends a 700W unit, so the power supply must meet both the wattage and connector count before purchase.

Questions about this item

How do I decide between the OC and the STD/Silent BIOS profiles on this card?

The OC profile targets a boost clock up to 2310 MHz and a game clock up to 2065 MHz, while the STD/Silent profile runs at up to 2250 MHz boost and 2015 MHz game clock for quieter operation.

What does the 16.0 Gbps effective memory clock mean for 4K gaming performance?

The 16.0 Gbps GDDR6 memory on a 256-bit bus delivers high bandwidth that feeds the 4608 stream processors, helping maintain frame rates at 7680 x 4320 resolution.

Will the PCI Express 4.0 interface limit bandwidth if my motherboard only has PCIe 3.0 slots?

The card works in PCIe 3.0 slots at reduced link speed; the 16GB GDDR6 and Infinity Cache architecture help offset any bandwidth difference in most titles.
