XFX’s version of the Big Navi graphics card, whilst having a name that’s a bit of a mouthful, brings with it improvements to clock speed and phase design, as well as more advanced cooling solutions to help cope with the increased performance demands.
Structurally the card has a triple-fan layout and takes up three case expansion slots. The aluminum cast tray functions as a support bracket for the card. This version of the card also comes with a USB Type-C connector.
The 14+2 phase PCB design is an increase over the 11+2 phases in AMD’s stock model. The Speedster MERC also comes with a dual BIOS switch as well as an upgraded “XFX Ghost Thermal” cooler, which is much larger than that on the original. The cooler comes with an aluminum fin array with seven 6mm heat pipes. Additional cooling improvements include vent holes in the backplate to allow one of the fans to push the air through the exposed heatsink in this direction.
The cooling upgrades are needed in order to compensate for the increased strain the CPU is under due to the factory overclock, which brings the base frequency up to 1925 MHz, the game clock to 2105 MHz, and the boost to 2340 MHz, compared to 1825 MHz, 2015 MHz and 2250 MHz respectively on AMD’s stock version.
Aesthetically, the 6900 XT Speedster MERC 319 is probably one of the better-looking graphics cards we’ve seen. The design is predominantly matte black, with silver detailing around the edges, on the fan sockets, and the shroud.
Price-wise the card typically retails for $100 more than the stock model (i.e. $1099 vs $999). As with most of the graphics cards launched in 2020, finding one in stock may prove a challenge, but the following retailers have the XFX Radeon RX 6900 XT Speedster MERC 319 listed:
