I thought the whole point of AMD skipping the 4000 series naming for their new Zen 3 desktop parts, was because the Zen 2 mobile APUs "ruined" the branding for Zen 3, and they wanted to stop mixing architectures.
If AMD is just going to mix Zen 2 and Zen 3 under the 5000 series branding regardless, then why did they rebrand the desktop parts to the 5000 series at all? It doesn't make a sense.
Then again, I don't know why they would waste their manufacturing capacity on a Zen 2 refresh when they already have a superior design being made with (probably) the same process?
