Despite all sorts of out-of-stock, crash exit and other issues, but in performance, NVIDIA RTX 30 series is still the same, AMD is also a frequent blower of the next generation of RX 6000 series, to their own is also to cheer the player. Now, for the first time, photos of the core of the Big Navi (Navi 21) used in the RX 6900 series have been exposed, and although the markings have been erased, they are still available, with a rough estimate of 536 square millimeters, which is close to the previous forecast of 505 square millimeters.
By contrast, the RX 5700 Navi 10 core is only 251 square millimeters, and the RX Vega 64 Vega 10 core area is only 495 square millimeters.
Of course, NVIDIA has done more on this side, with the RTX 3080/3090 GA102 core already covering 628 square millimeters, the RTX 2080 Ti TU102 core 754 square millimeters, and the RTX 2080 TU104 545 square millimeters almost the same as Big Navi.
As you can see, Big Navi is a standard package core, there is no integrated package HBM2 around, with the GDDR6, the cost can be better controlled.
The current news shows that the RX 6900 XT will be paired with 16GB GDDR6 memory, but the bit width probability is only 256-bit, do not rule out the possibility of reaching 512-bit but the hope is not great.
The AMD RX 6000 series will have three cores in the layout, Navi 21, Navi 22, and Navi 23, corresponding to the RX 6900, RX 6800, and RX 6700 series, respectively, and will premiere on October 28.
On the next day, the RX 3070 will follow. Given rumors that the RX 6900 XT will only perform slightly better than the RTX 3070, NVIDIA is clearly waiting for AMD to make a move and then start.
