XFX Speedster MERC 319 BLACK Radeon RX 7800 XT 16GB Graphics Card

The Speedster series exemplifies a modern aerodynamic style through a clean and elegant design. It is a thoughtful design with the sole purpose of maximizing airflow to improve cooling and performance. With each iteration of the XFX Merc series, we have simplified the design while improving performance. This newest iteration introduces our all-new ridged backplate design which increases the overall surface area by 33%, the results are increased in heat dissipation when paired with thermal pads. Our new design features a straight-through airflow venting to significantly improve cooling and compliments the open design of the Ghost Thermal floating shroud design along with numerous other cooling features.
