16GB GDDR6 for 4K gaming
The XFX Speedster MERC 319 Radeon RX 6800 XT CORE delivers 16GB of GDDR6 memory across a 256-bit interface. It targets enthusiasts who want high frame rates at 4K resolution in modern titles. The AMD RDNA 2 architecture provides 4608 stream processors for rasterisation and ray-tracing workloads. A PCI Express 4.0 link ensures full bandwidth to current platforms.
Triple-slot cooler fits standard ATX cases
Installation follows the usual PCI Express 4.0 x16 slot procedure with two 8-pin power connectors. The 319-length triple-slot design clears most mid-tower cases but can block adjacent PCIe slots on tighter boards. Ensure the power supply cables reach without sharp bends and that case airflow feeds the three axial fans directly. Driver installation is standard through AMD Adrenalin software.
Game Clock 2015 MHz sustained under load
The card runs at a 2015 MHz Game Clock during typical gaming sessions rather than the 2250 MHz boost figure seen in short bursts. Thermal headroom from the MERC 319 cooler keeps clocks stable during extended play. Memory operates at 16000 MHz effective across the 256-bit bus without throttling. Outputs include one HDMI 2.1 and three DisplayPort 1.4 connectors for multi-monitor setups.

Questions sur cet article
How can I verify the card is running at its 2250 MHz boost clock after installation?
Use AMD Radeon Software or a tool like GPU-Z to monitor the real-time frequency while a demanding game runs; the reading should approach 2250 MHz when thermals and power allow.
What cables or adapters are included in the box versus what I must source myself?
The box contains the graphics card and a quick-install guide; you must provide a PCIe 4.0 motherboard slot, a power supply with the required 8-pin connectors, and your own HDMI 2.1 or DisplayPort 1.4 cables.
Which version of this model should I pick if I need 16 GB of video memory?
This SKU is the single 16 GB GDDR6 configuration with a 256-bit bus, so there is no alternative capacity to choose from.
