I noticed that it is an AMD platform (i.e. A+A). It is quite normal
that AMD's iGPU requires more memory than Intel's (because it is also
more powerful). This should be a normal behaviours.
This can depend on hardware design, but the iGPU device allocates 256M
memory space (see lspci or below) and I am also guessing this is the
system memory dedicated to iGPU. If the 256M system memory is taken
into consideration, ex. the calculation becomes (4x1024 - 256) /
(3.13x1024) = 83.4%, this passes the criteria.
