The 128-core CPU is interesting, and AMD Zen4 processor samples have come out: 5nm process, area 80mm2.
AMD promises to launch 7nm+ process Zen3 processor this year, and then the new 5nm process Zen4 , EPYC server processor "Genoa" will first launch Zen4.
Earlier information indicated that Zen4 should come out in 2022, but it may be ahead of schedule now.
AMD now has 5nm Zen4 samples, which means that Tapeout is complete.
TSMC will mass-produce the 5nm process this year.
In 2021, 7nm and 5nm production capacity can be Up to 200,000 wafers, far exceeding the current level. On the other hand, the progress of Zen3 should be in the final stage of listing. Tapeout and verification have passed.
It is reported that although the detailed specifications of Tapeout's 5nm Zen4 chip are unknown, the core area is about 80mm2, which is 10% higher than the current 7nm Zen2 core area of 74mm2. TSMC claims that the 5nm process can increase the density of transistors by 80% compared to the 7nm process. In this way, the 5nm Zen4 core can accommodate at least 12 cores and more than 16 core CPU cores under 80mm2, which is double the current Zen2. Of course, the actual number of cores that can be achieved in each chip depends on AMD’s architecture design. In theory, there is a possibility of doubling. In this way, AMD can create EPYC processors with up to 128 cores and 256 threads single layer, mainstream desktops Ryzen is not impossible to upgrade to 32 cores.
NOTE: the news are not coming anymore from US as from some time ago ASiA is the main news channel..
