ASUS has silently updated its ROG STRIX LC Radeon RX 6900 XT graphics card with the new TOP variant which packs the AMD Navi 21 XTXH GPU. The AMD Navi 21 XTXH GPU is a binned design that offers higher clock speeds & more overclocking headroom which should be expected of a custom graphics card such as the ROG STRIX LC.

The ASUS ROG STRIX LC Radeon RX 6900 XT TOP is a full-on liquid-cooled design that makes use of the ROG STRIX Radeon RX 6900 XT PCB but couples it with the power of liquid cooling. The liquid cooler features a 240mm radiator that has braided tubing leading to a custom pump model that has been designed specifically for the Navi 21 "RDNA 2" GPU. The shroud on the Radeon RX 6900 XT ROG STRIX LC card itself is gorgeous with a stunning display of ASUS's AURA SYNC RGB lighting and a futuristic shroud design. The shroud also comes with a blower-style fan that will blow air through the internal chassis of the graphics card.
