PowerColor HellHound Radeon RX 7800 XT Spectral White Introduction

PowerColor has introduced the HellHound Radeon RX 7800 XT Spectral White edition as part of the 7800 XT lineup. This edition stands out with its entirely white design - encompassing the PCB, heatsink, and even the cables. Beyond its aesthetic appeal, the unit has undergone factory modifications to provide an enhanced cooling system. Users can expect a quiet operational experience coupled with a performance uptick of approximately 3%. Designed for reliability, it ensures an optimal gaming experience without any operational drawbacks, while maintaining efficiency and cooling. The graphics card is offered at a competitive price point of $539.

With a 2520 Boost frequency, 228W TGP, the card aims for efficiency. Relative to the reference design, this 3-slot variant can achieve a slightly elevated clock speed. Notably, the product is equipped with dual 8-pin power connectors. The Radeon 7800 XT with its 16GB 256-bit memory configuration at 19.5 Gbps, is bound to impress. This particular iteration is poised to utilize the complete 60 CU / 3840 Shader processors setup of the GPU and boasts a Total Board Power (TBP) of 263W. The AMD Radeon RX 7800 XT GPU is built upon the Navi 32 SKU framework and thus chiplets, incorporating four Memory Controller Domains (MCDs). The GPU core boasts 3840 cores, meticulously distributed across 60 Compute Units to enhance performance. Additionally, the GPU incorporates a substantial 64 MB Infinity Cache, functioning at a 19.5 Gbps pin speed, yielding a commendable total bandwidth of 576 GB/s.

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.
