AMD’s next-generation graphics cards may mix RDNA3 and RDNA2
AMD just released RDNA2’s mid-range mainstream graphics card RX 6600 XT last week, next, RDNA2 is estimated to have RX 6600 and more entry-level RX 6500 series graphics cards. But now someone is breaking the news about AMD’s next-generation Radeon RX 7000 graphics card. Rumors say that AMD may use both RDNA3 and RDNA2 GPUs in the next generation of graphics cards.
According to @greymon55, only Navi 31, 32, 33 is based on RDNA3.
For the rest of the Radeon RX 7000 portfolio, AMD thus seems to have two options:
1) 6nm refreshes of Navi 24, 23, 22
2) further use of Navi 24, 23, 22, possibly with new card nameshttps://t.co/7nKEPVC9lZ pic.twitter.com/vSjcNQXTvE— 3DCenter.org (@3DCenter_org) August 16, 2021
This rumor was reported by Twitter user @greymon55 to 3DCenter, in AMD’s next-generation graphics card RX 7000 series, the high-end RX 7900, RX 7800, and RX 7700 will use the RDNA3 architecture. These GPUs include Navi 31, Navi 32, and Navi 33. Among them, Navi 31 and Navi 32 use MCM architecture, which may be a mixed package of 5nm and 6nm. Navi 33 is a single chip, it has the same 5120 stream processors as the current Navi 21.
The RX 7600, RX 7500, and RX 7400 series graphics cards will use the 6nm version of Navi 22, Navi 23, and Navi 24 cores. TSMC’s 6nm process is actually an upgraded version of 7nm. In theory, after adopting the new technology, there will be lower heat generation and higher frequency.
