AMD's rDNA two architecture graphics card has been officially released for some time now, and the release of the RX 6900 XT is a clear indication of where the RTG team is going -- back to the high end. The RX 6900 XT is only superior in power consumption to its rival flagship but still a bit behind in absolute performance. With so much catching up, no one wants to give up the chance to take the throne. Now, as time goes on, some rumors about rDNA three architecture graphics cards are beginning to surface, and AMD's long-mooted MCM technology is highly likely to be implemented on rDNA three flagship graphics cards. And in terms of specs, AMD is going to expand a lot. Its flagship model will use a dual 80CU design, which means a superjumbo graphics card with 160CU units.
It started with Twitter user Kepler saying that AMD's Navi 31 will have two chiplets and a dual 80CU design, although I'm not 100% sure.
But at that time, many people thought this is a crazy dream; there is no basis, naturally did not cause attention.
Then Twitter user Underfox found an AMD MCM patent for an MCM-based GPU that harmonizes ray tracking performance between the two chips. This technique is likely to be present in the rDNA three architecture. In combination with AMD's promise to continue to improve the power consumption of rDNA 3, we can see that rDNA 3 is a new graphics architecture to look forward to. However, no specific release date has been announced yet, with some saying that rDNA three graphics will not be released until the first quarter of 2022 at the earliest. If, for some reason, it was delayed, it would be even later.
