I do not understand that. The integrated graphics device uses the system RA=
M=20
as VRAM doesn=E2=80=99t it? So why does it have to be evicted at all? Also,=
I believe
it=E2=80=99s 1 GB of VRAM. That means the speed would be 3 GB/s, where it s=
hould be
much higher with DDR4 shouldn=E2=80=99t it?

I=E2=80=99ll try to figure that out.
