Intel's pioneering 3D X-point Memory, which sought to bridge the gap between non-volatile Flash memory, and volatile DRAM, stares at an untimely demise, as Intel plans to wind up both its Optane Memory business, as well as further development of 3D XPoint. The industry's reception of Optane Memory has been lukewarm; while cheap NVMe SSDs have driven Optane out of the client segment. Intel in its Q2-2022 Financial Results release, announced that it has initiated the winding down of the Optane Memory business, and that the company is incurring a $559 million "Optane Memory Impairment" charge this quarter.

3D XPoint faces technological competition from the latest crop of 3D-stacked Flash memory, which is achieving over 200 layers of density; while the latest generation of PCI-Express Gen 5.0 controllers enable data-rates in excess of 10 GB/s, and certain enterprise-relevant features of PCIe Gen 5. In a statement released to AnandTech, Intel says: "We continue to rationalize our portfolio in support of our IDM 2.0 strategy. This includes evaluating divesting businesses that are either not sufficiently profitable or not core to our strategic objectives. After careful consideration, Intel plans to cease future product development within its Optane business. We are committed to supporting Optane customers through the transition."
 
I'm surprised it took Intel this long to shut down the optane memory production. 
 

As Thanos said, it was inevitable. Can't sell a product you can't produce, and was too expensive to compete with NAND. With CXL 2.0 and DDR5's higher density metrics over DDR4 chips the niche Optane was designed to target in server Optame-memory modules is evaporating.
