Verdict

The ASUS ROG Strix LC Radeon RX 6900 XT Gaming OC is a high-performance liquid-cooled graphics card featuring the AMD RDNA 2 architecture with 5,120 stream processors and 16GB of GDDR6 memory on a 256-bit bus. Designed for extreme overclocking, it boasts a boost clock of up to 2525 MHz and a game clock of 2375 MHz, supported by a 240mm radiator and a full-coverage cold plate that cools both the GPU die and VRAM. Its main pros include exceptional thermal management that keeps load temperatures significantly lower than air-cooled variants, a relatively slim 2.2-slot design for better case compatibility, and premium Super Alloy Power II components for stable power delivery. However, notable cons include its high initial price point, the requirement for significant internal case space to mount the external radiator, and occasional reports of audible coil whine under heavy workloads.
