"Each megabyte of 3D Xpoint will certainly be significantly cheaper than the equivalent amount of Ram. And the new technology has the added advantage of being non-volatile, meaning it does not "forget" information when the power is switched off.
But, unfortunately it is still not quite as fast as Ram, and some - but not all - applications need the extra speed the older tech provides."
