That is Samsung's MO, but it hasn't worked especially well with Exynos in the past. Part of it is that Samsung SLSI doesn't have the kind of support structure that Intel, AMD, Qualcomm, Mediatek, or even RockChip have to enable customer designs. The bigger issue though is that just about every OEM has been burned at some point by relying too much on Samsung. You can work around that with memory and to some extent displays, but taking that risk on a CPU is rough.
