I think they moved away because system memory was lagging behind in speed to the memory being used on video cards?
And besides, what Apple is doing is placing the RAM really close to the SoC, I think they are on the same package even, that was not the case on the PC either AFAIK?
Apple has an arm license but they still buy memory from Samsung (and others), it's not on the m chip die but it's provided by Samsung and then packaged above the m die.
