According to the latest YouTube video of Moore’s Law Is Dead, AMD has reduced its upcoming RDNA4 lineup and shifted more energy to RDNA5.
In the video, MLID starts by citing an AIB source who said that RDNA4 “will not achieve a complete performance improvement in terms of the stack.”

In addition, it is reported that AMD has cut the RDNA4 product lineup. In order to avoid repeating the mistakes of “RDNA3”, it has decided to cut off the Navi42 and Navi41 high-end product lines but will retain the Navi43 and Navi44 SKUs.
It is reported that AMD encountered a large number of “random problems” during the development of Navi41, which is believed to be the main reason why AMD cut Navi41.

The report also said that another reason for AMD to cut off RNDA4 high-end products is to accelerate the development of the RDNA5 lineup and ensure that the remaining RDNA4 products will not be delayed.
MLID also said that AMD’s RDNA5 development is “progressing well” and that the early performance gains are “exciting.”

According to reports, AMD will release Navi44 in mid-2024, which is expected to use a 6nm process; Navi43 will be released in 2025, which will use a 3nm process node, allowing more CUs to be packaged in a smaller volume.
