Verdict

The PowerColor Liquid Devil Radeon RX 7900 XTX is a flagship RDNA 3 graphics card featuring a pre-installed custom EK water block, a premium 14-layer PCB with a 17-phase VRM, and 24GB of GDDR6 memory on a 384-bit bus. It boasts significant factory overclocks with a boost clock of up to 2,680 MHz in 'Unleashed' mode and high-end connectivity including DisplayPort 2.1 and HDMI 2.1. Main pros include its exceptional cooling efficiency that maintains low temperatures under heavy loads, a space-saving single-slot design, and massive rasterization performance for 4K gaming. However, its primary cons are the requirement for an existing custom liquid cooling loop, relatively high power consumption necessitating at least an 800W PSU, and ray tracing performance that still trails behind competing NVIDIA high-end offerings.
