Features: RDNA 2 architecture, 7nm core process, GDDR6 brings smoother gaming experience, support PCIe 4.0 bandwidth. 2*9cm large size cooling fans deliver more airflow, combined with 3*6mm pure copper nickel-plated heat pipes and large area aluminum heat sink for better heat dissipation. Intelligent fan speed adjustment, the fan speed will adjust automatically according to the load condition. The full-covered metal backplate fully protects back components to make graphics card stronger and more durable. Multiple cooling hole design, further auxiliary heat dissipation. Adopt non-reference PCB and high-quality components to ensure long-term stable high-performance output.
