Entering 2021, it's time for AMD's next generation graphics card to be exposed. The replacement of last year's rdna2 should be the rdna3 architecture under development, code named Navi 3x. Among them, navi 31, the flagship of large core, may use MCM multi chip architecture, twice the scale. Although the cDNA architecture on the computing card has achieved 120 groups of Cu units, the rdna2 architecture for games now has up to 80 groups of Cu units. The rdna3 architecture needs to continue to add Cu units, but the implementation method is somewhat special.
According to Twitter users, the next-generation flagship core Navi 31 may adopt MCM multi chip packaging design,It is composed of two groups of chips, each of 80 groups of Cu units, which together will be 160 groups of Cu units. The scale will be doubled, and the theoretical performance will also be doubled.
In addition to the unexpected doubling of computing scale, rdna3 will also strengthen its light pursuit,
It was also disclosed earlier that AMD has developed a new technology based on MCM and a new command processor to coordinate the optical pursuit of the next generation of GPU, which may be developed for rdna3.
As for the release time of rdna3 graphics card, it should be corresponding to zen4 architecture in CPU. With 5nm technology, it will come out in 2022. The fastest release time is at the end of this year, similar to rx6000 graphics card last year.
