The developers of the new memory type do not disclose manufacturing costs or estimated prices of actual devices based on 3D XPoint devices. Officially, Intel and Micron say that the costs of 3D XPoint devices are somewhere between costs of NAND flash and DRAM. Keeping in mind that one 128Gb MLC NAND chip costs $7.5, whereas one 4Gb DDR3 DRAM chip costs $2.3 (which means that DRAM is 10 times more expensive in terms of per gigabit cost), it turns out that 3D XPoint will be significantly more expensive than modern NAND flash.
