The Radeon RX 6900 XT LC was supposed to be exclusive to Sapphire only but Power Color is also expected to launch the SKU.
A Twitter user @momomo_us has discovered that PowerColor listed its Radeon RX 6900 XT LC which they removed later. This proves that the card is not a Sapphire exclusive. There is a possibility that other brands will also launch this card under their name.
The Radeon RX 6900 XT LC is based on a hybrid cooling design with an external 120mm radiator and a single fan. The liquid loop is located on the top of the GPU which has a connection to the pump. Currently, it is unclear who has designed this liquid cooling, but there is a possibility that AMD might have partnered with Cooler Master, who designed the liquid cooling for the Radeon RX Vega 64 Liquid Edition.
Till now, the specifications for this graphic card are unconfirmed, but yesterday’s pre-launch review revealed that it has a Navi 21 XTXH GPU with a 2250 MHz game clock and 2435 MHz boost clock. Moreover, At least two sources now believe that this model might have 18 Gbps GDDR6 RAM. There is no information on pricing and release date yet.
