XFX Speedster MERC319 Radeon RX 6800 XT
The XFX Speedster MERC319 Radeon RX 6800 XT is a refurbished graphics card built on the AMD RDNA 2 architecture. It delivers 4608 stream processors and 16GB of GDDR6 memory across a 256-bit interface. The card targets gamers and creators who need high frame rates at 1440p and 4K resolutions.
Upgrade path from older GPUs
This model replaces cards based on the RDNA 1 architecture or earlier GCN designs. The jump is worth it when your current GPU cannot sustain 60 frames per second in modern titles at your target resolution. The 16GB buffer also removes the texture-streaming bottlenecks seen on 8GB and 10GB cards.
Sustained load behaviour
Under continuous load the triple-fan cooler manages the 300W thermal design power while the boost clock holds at 2250 MHz. A 750W power supply is the minimum requirement and an 850W unit is recommended for stable operation. The 2 x 8-pin connectors deliver consistent current during extended gaming or render sessions.

Questions about this item
How much case length and slot width does the triple-fan MERC319 cooler need?
The card uses a triple-fan cooler and occupies two expansion slots; measure your case for dual-slot clearance and enough length for a full-size 16 GB graphics board.
Which power cables must be connected before the 300 W board turns on?
Plug both 8-pin connectors from a 750 W or larger supply into the card; the system will not boot if either connector is left unattached.
When should the thermal paste under the triple-fan heatsink be refreshed?
Re-paste the GPU die if temperatures climb noticeably after several years of heavy load; the 16 GB GDDR6 memory pads rarely need attention unless artefacts appear.
