AMD launched its Ryzen 5000 desktop processor lineup back in 2020. The CPUs were based on the TSMC 7nm Zen 3 architecture. Although the processors performed very well, one thing noticeably different about Ryzen 5000 series was the missing SKUs that had generally been present in previous-gen Ryzen lineups. To be specific, the Ryzen 5000 series did not feature a Ryzen 7 5700X or Ryzen 7 5700, Ryzen 5 5600, and no Ryzen 3 SKUs.
However, a new rumor alleges that AMD may be ready to finally launch a Ryzen 3 processor, in the form of the Ryzen 3 5500, alongside the Ryzen 5 5600 and a Ryzen 7 5700X, and they are coming by the end of this month. The rumor originates in the Chiphell forum (via HXL on Twitter).
Hence if this rumor turns out true then the Ryzen 5000 lineup will not only have a new flagship-tier product in the form of the already-announced Ryzen 7 5800X3D with 3D V-cache, but also more affordable options too.
As a consequence of the chip shortage, the TSMC 7nm process used by AMD for its Ryzen 5000 parts was in high demand and so it's possible that there weren't enough yields to manufacture more chips. But the yields for 7nm may be improving finally giving AMD the option to release these more affordable parts.
