Entered 2021 years, AMD's next-generation graphics card is the exposure time, replacing last year RDNA2 should be developed in RDNA3 architecture, code-named Navi 3X, including large-core flagship Navi 31 is possible to use MCM multi-chip architecture, 2 times the size.
Although the cDNA architecture on the computing card has achieved 120 groups of CU units, the RDNA2 architecture for games now has a maximum of 80 groups of CU units. The RDNA3 architecture will continue to add CU units, but the implementation method is somewhat special.
According to Twitter netizens, the next-generation flagship core Navi 31 may adopt MCM multi-chip packaging design. It consists of 2 sets of chips, each with 80 sets of CU units so that together is 160 sets of CU units, which is double the size and theoretically performance. Will double.
In addition to the doubling of the computing scale, RDNA3 will also strengthen the optical chase. Although the RX 6000 series graphics cards launched last year also support hardware optical chase, the performance is not as good as the RTX 30 series. AMD has to continue to improve.
Earlier news broke that AMD has developed a new technology based on MCM and a new command processor to coordinate the light pursuit of the next-generation GPU. It may be developed for RDNA3.
As for the release time of the RDNA3 graphics card, it should correspond to the Zen4 architecture in the CPU, using the 5nm process, and coming out in 2022, the fastest is the end of this year, similar to last year's RX 6000 graphics card.
