AMD going hybrid is even more older news.
What do you mean?
Isnt Zen 4 confirmed to still be the chiplet design?
What is AMD using for their E-cores?
EDIT: Looks like you are basing AMD going hybrid on a patent for whats either Zen 5 or Zen 6.
As in after 2024/5.
Not something id be worrying about right now considering by then Alderlake and Raptorlake will have been out a while and DRM makers will have figured out how to get their software to work with hybrid systems.
P.S Intel is already working with "popular" DRM makers to have their solutions working out of the box.
I dont think this is anything to worry about.
Its Intels dev FAQ just ticking all the boxes for developers to understand that if their DRM software doesnt recognize multiple architectures in a system it might go wonky.
