I just thought 2 combined ᴄᴘᴜs or 2 combined ɢᴘᴜs were better than 1. Even in
the case the power of 1 of the part has an insignificant power compared to
others.

That’s why I wrote :

> bad ?
By comparison, Direct3D 12 developers don’t use software rendering when they
use several ɢᴘᴜs, because the Microsoft Software rendering engine don’t show up
as a ɢᴘᴜ.
(though the Microsoft rendering engine doesn’t use ꜱɪᴍᴅ at all contrary to
llvmpipe).
I don’t see any reason for not getting rendering faster in that Vulkan case
(It’s up to the programmer to decide to use multi‑ɢᴘᴜs configurations or not).
At least the aim is to not make the llvmpipe ɢᴘᴜ different from others ɢᴘᴜs at
the ᴀᴘɪ level.

It wasn’t in the idea in running Vulkan on only ᴄᴘᴜs of course.


I already wrote such feature should be made optional at run‑time. So there’s
would be no problems for users fearing overheat.
