https://wccftech.com/amd-big-navi-21-gpu-for-flagship-radeon-r9-6900-xt-graphics-card-allegedly-pictured/ > An alleged picture of AMD's Big Navi "Navi 21" GPU which would power the next-generation flagship, Radeon RX 6900 XT, graphics card has been leaked out by Coreteks. Powered by the RDNA2 architecture, the AMD Big Navi GPU looks to be massive in size when compared to past AMD flagship GPU offerings. > Coreteks has removed all references and labels over the GPU die to mask his sources but he did state that the GPU we are looking at is indeed the Big Navi "Navi 21" GPU which is going to be featured on the flagship Radeon RX 6900 XT graphics card. The GPU seems fairly large & is said to measure at around 536mm2 though those are just rough calculations and the final die size could be higher or lower. The die size also seems to be close to the previous rumors which pointed out a 505mm2 die size for the flagship GPU.
