The graphics card, with a boosted frequency of 2520 MHz, boasts a contemporary white aesthetic. It features two operational modes: OC and Silent, with power targets set at 228W and 212W, respectively. A BIOS switch is conveniently located on the card's top side. In Silent mode, the card operates exceptionally quietly, averaging around 650-700 RPMs in our tests, and remains relatively silent even in OC mode. The specifications for OC mode are Game 2213 MHz/Boost 2520 MHz, and for Silent mode are Game 2124MHz/Boost 2430MHz. Additionally, the card comes with 19.5 Gbps memory and a 256-bit memory interface. The board incorporates a 14-layer PCB design, supported by a 15-phase power design (9+2+1+2+1), ensuring enhanced stability and overclocking potential. Capable of handling well above 300W, this robust VRM configuration ensures cooler operations and better reliability. The design utilizes DrMOS with built-in IMON real-time digital monitoring, ensuring no compromises in quality. The cooling solution is an advanced triple ringed-fan system (100 x 90 x 100mm), complemented by five 6φ heatpipes. While the card does not support RGB, it offers two color options: Ice Blue and Amethyst Purple. Users can also opt to turn off the lighting for a more subdued look.
The HellHound card showcases a distinctive I/O layout, powered by dual 8-pin connectors. Aligned with AMD's MBA card specifications, this model is equipped with a single HDMI 2.1 connector and three DisplayPort 2.1 ports. For optimal thermal regulation, a tri-fan cooling design ensures maximized airflow around the backplate. By default, the card runs in performance mode, offering a 3% performance enhancement over standard reference models. Notably, the Radeon RX 7800 XT will employ standard 8-pin PCIe connectors, requiring two of them, rather than transitioning to the 12VHPWR port.
