On the internet, we finally heard that the first-ever benchmark testing score of the AMD Radeon RX 6900 XT LC ‘Liquid Cooled’ graphics card has appeared. The results are published by the content creators at Bili Bili. Results conclude that the cards offer a slight performance boost along with lower temperatures thanks to the liquid cooling setup.

Reports also suggest that AMD Radeon RX 6900 XT with Navi 21 XTXH chips will also be fitted with high-end cooling systems, both air, and liquid from various manufacturers. AMD has followed the liquid approach. Some of the top variants that feature the Navi 21 XTXH GPU include:

ASUS ROG STRIX LC Radeon RX 6900 XT TOP
Sapphire Radeon RX 6900 XT TOXIC Extreme
PowerColor RX 6900 XT Red Devil Liquid Devil Ultimate
ASRock’s RX 6900 XT OC Formula

From the benchmark, it was also revealed that the cards will follow the same design scheme as the existing Radeon RX 6000 RDNA 2 series graphics cards with a silver and black color scheme. It will also feature a dual-slot design and will also come with an AIO liquid cooling solution. Its also been reported that the card will feature a 120mm AIO radiator and has an RGB accent LED on the side. The card features the reference PCB design with dual 8-pin power connectors.

Coming to the benchmark test, the GPU managed to offer up to 5% performance uplift over the reference Radeon RX 6900 XT in synthetic workloads. The content creator also posted a Furmark benchmark.
