Look at the size of that memory controller! It must be half a billion transistors in itself. It is such a waste to have all those transistors, and yet none of them are used to govern the OS storage space. Talk about a serious flaw in PC design...
Sadly, the results are in; DDR4 is all but useless. It offers nothing measurable to justify the obsolescence of DDR3.
