Speedster Series
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.

Airflow and Aesthetics
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.

XFX Ghost Thermal

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.

Vapor Chamber

The XFX MERC 319 7800 XT uses a vapor chamber design, a more efficient method for heat dissipation than traditional cold plates alone. The vapor chamber can quickly quickly and efficiently transfer heat from the GPU and VRAM to the heat pipes, and then into the heatsink assembly.


XFX Dual BIOS Ready

We know enthusiast like options, so for the XFX MERC 319 7800 XT graphics cards, we are offering dual BIOS. Giving a backup BIOS in the case of a failed BIOS update or flash.

High Efficiency 13-Blade Fans - Quieter & Longer Lifespan

The MERC 319 7800 XT GPUs utilize 13-blade structure fans that provide better endurance and efficiency over other designs. Reducing friction and heat these, fans operate quieter and have increased lifespan.

Extreme Stability and Overclocking

With a 14-phase power design, and a dedicated 9-phases for GPU GFX Core, the MERC 319 7800 XT provides you with stable gameplay and gives better power distribution across the VRMs. This allows the GPU to operate cooler at baseline but also has tremendous room to overclock thanks to XFX's increased power delivery BIOS.
