ROG STRIX Radeon RX 6800 16GB

This ASUS ROG STRIX graphics card targets enthusiasts who want high-frame-rate 1440p or entry-level 4K gaming. The AMD Radeon RX 6800 GPU delivers 3840 stream processors and a 2190 MHz boost clock. Sixteen gigabytes of GDDR6 memory on a 256-bit bus provide ample bandwidth for modern titles. The PCI Express 4.0 interface ensures full throughput on compatible platforms.

Power and slot requirements

Verify that your power supply meets the 650W recommendation and provides two 8-pin PCIe connectors. The card occupies a 2.9-slot thickness, so confirm case clearance and motherboard spacing before ordering. A PCI Express 4.0 slot is required for peak bandwidth, though the card will operate in 3.0 slots at reduced speed. HDCP 2.3 support is built in for protected content playback.

Cooling and build upgrades

The Axial-tech fan design uses additional blades and a revised rotation pattern to move more air through the heatsink. MaxContact technology creates a tighter surface between the GPU die and the heat spreader for improved thermal transfer. Super Alloy Power II components include premium alloy chokes, solid polymer capacitors and high-current power stages for stable delivery. Outputs comprise one HDMI 2.1 and three DisplayPort 1.4a connectors for up to four displays.

Questions about this item

What comes in the box and which cables or adapters must be purchased separately?

The card includes the triple-fan cooler, 2 x 8-pin power connectors and the metal backplate; no HDMI or DisplayPort cables are bundled, so buy those separately if your monitor does not already have them.

How do I choose between the available versions or capacities of this model?

This SKU is a single configuration — 16 GB GDDR6 on a 256-bit bus with a 2190 MHz boost clock — so there are no alternative memory sizes or clock variants to select.

What does the 2190 MHz boost clock mean once the card is installed in my system?

It is the peak frequency the GPU can reach under load when power and temperature headroom allow; sustained speeds will vary with your case airflow, PSU quality and driver settings.
