Detailed over at Videocardz.com, the render does reveal a few details, including dual 6+2-pin and single 6-pin PCIe power connector, which means that the RX 6900XT Toxic can draw a total of 450W, giving it a lot of overclocking headroom. Unfortunately, the actual specifications are still unknown.
We expect Sapphire to include a hefty factory-overclock and we are sure that the 360mm radiator won't have any problem in keeping the Navi 21 GPU well cooled.
Hopefully, Sapphire will officially announce the new Toxic graphics card soon and we'll get the rest of the specifications.
