Navi 31 XTX with its new chiplet design

It appears that an AMD Radeon RX 7900 XTX was in the works, implying that the original XT model will no longer be the company's top dog. The product will come out in early December. Two cards, the 7900XT and 7900 XTX, are announced. They are based on the Navi 31 GPU, which has RDNA3 architecture and is based on a new chiplet design. Yeah, chiplets man, and it's a big GPU, alright. The die area of the Navi 31 graphics processor chip is 300 mm2.
