In October last year, it was reported that THE TOP CHIP NAVI 31 in AMD's next-generation RDNA 3 architecture had been tapeted, which was an important step in the process of GPU marketing. From tape-out to bulk shipment, it generally takes about 8 months. As AMD's first consumer GPU to use MCM multichip packaging, the project cycle may be longer, and there will be more time to work on it.
Some netizens revealed that Navi 31 has recently appeared in AMD's changelog, which shows that the entire RDNA 3 architecture plan is proceeding step by step, and there is no big doubt about the launch this year.
At the 2021 earnings call earlier this year, AMD CEO Dr. Su Zifeng confirmed that there will be several important product launches during the year, including CPUs based on Zen 4 architecture and GPUs based on RDNA 3 architecture. Around the same time, AMD engineers listed each of the new Navi 3x series GPUs in their Linkedin profile (which was later removed).
In the Navi 3x family of GPUs, the Navi 31 and Navi 32 will use MCM multi-chip packages, and GCD (graphics computing chip) and MCD (multi-cache I/O chips) will use two different process processes, namely TSMC's 5nm and 6nm processes, while the Navi 33 will still be a single chip.
AMD is rumored to make changes to the original structure, no longer the original CU compute unit, will use WGP as the main compute module, each WGP has 256 stream processors. The Navi 31 will have 60 WGP, or 15,360 stream processors, the Infinity Cache will be 512MB, and the memory bandwidth will remain at 256 bits. In addition, AMD does not appear to be planning to introduce a 16Pin 12VHPWR interface on the Radeon RX 7000 series.
