What we like about PowerColor Liquid Devil Radeon RX 6900 XT Ultimate

  • Exceptional performance as one of the fastest RX 6900 XT variants due to high-binned 'Ultimate' silicon (XTXH chip)
  • Superior thermal management provided by the pre-installed custom EK water block
  • High overclocking potential with unlocked BIOS limits and high-quality power delivery
  • Premium aesthetics including a nickel-plated copper base and customizable RGB lighting
  • Includes thoughtful extras such as EK Cryofuel coolant dyes and a BIOS switch for OC/Silent modes

What we don't like about PowerColor Liquid Devil Radeon RX 6900 XT Ultimate

  • Requires a custom water cooling loop for operation, adding significant cost and complexity for the user
  • High power requirements necessitating three 8-pin PCIe connectors and a robust power supply
  • Noticeable coil whine reported by some users, which can be irritating in quiet setups
  • Large physical dimensions (significant height) may cause clearance issues in smaller PC cases
  • Significant price premium over standard air-cooled 6900 XT models for marginal real-world gaming gains

Verdict

The PowerColor Liquid Devil Radeon RX 6900 XT Ultimate is an enthusiast-grade graphics card featuring a specially binned Navi 21 XTXH GPU, 5,120 stream processors, and 16GB of GDDR6 memory on a 256-bit bus. Designed for custom water-cooling loops, it comes pre-installed with a high-performance EK full-cover water block and a powerful 14+2 phase VRM system requiring three 8-pin PCIe connectors to handle its 332W power delivery. Its main pros include elite-tier overclocking potential with boost clocks up to 2,525 MHz, near-silent operation at low temperatures, and high-end aesthetic customization through an included dye pack. Main cons include its requirement for a complex custom liquid cooling loop, a massive physical footprint that may not fit standard cases, and a high premium price tag compared to air-cooled models.
