I'm from the nand flash industry. There seem to be a few fundamental improvements in XPoint. For one, achieving a 3X endurance improvement while keeping the same process size (dimensions of the memory cell) is new. Given that XPoint is byte addressable is rather impressive as the circuitry and metal layers (wires) needed for this is a lot more than page addressable nand. The true test is when they connect it directly to DIMMs versus the PCIE bus. Latency numbers there may further prove fundamental improvements in technology.
