AMD Radeon™ RX 6600 XT graphics cards deliver serious 1080p gaming and ultra-high frame rates. Get up to 32 high-performance compute units, groundbreaking AMD Infinity Cache, and up to 8GB of dedicated GDDR6 memory. Experience the next gen of gaming performance with AMD Smart Access Memory technology when you pair an AMD Radeon™ RX 6600 XT graphics card with an AMD Ryzen™ 5000 Series desktop processor.

Finding the balance between a good looking card and maximizing it's performance is an art. Where we could improve airflow, we did it, we opened it up while keeping the design clean and cool.

XFX's all new Ghost Thermal design cools your GPU better than ever before. Our new design features a straight through airflow venting to significantly improves cooling and compliments open design of the Ghost Thermal floating shroud design. Our new 13 blade fans increase total air flow and provides long lasting quieter operation.

We know enthusiast like options, so for our MERC 308 RX 6600 series graphics cards we are offering dual BIOS. Giving a backup BIOS in the case of a failed BIOS update.

XFX Fans are equipped to run at the highest possible performance, while our Zero DB fan system will also keep your fans running at efficient RPM in order to minimize annoying fan noise by lowering RPM all the way down to Zero RPM. When the heat is on during intense gaming, our fans will speed up as needed.
