Citing a lack of demand, Intel is going to stop selling its Core+ processor packages that come bundled with Optane Memory modules.

These packages were mostly aimed at OEMs, though could also be bought in retail channels, like Newegg. There are three models—Core i7+ 8700, Core i5+ 8500, and Core i5+ 8400. Each one came with a regular version of the specified processor (Core i7-8700, Core i5-8500, and Core i5-8400), plus a 16GB Optane Memory stick.
