The article appears to misunderstand the point of the project, and mostly just describes what zswap already does (writing compressed pages back into ram), rather than talking about cram's hardware-offloaded compression that allows cacheline-level access rather than page-level. (And they appear to be aware that they don't really understand it: “My explanation of CRAM might not be completely correct”)
The phoronix article is better, and I say that as someone who usually detests the quality of phoronix's technical writing.

Nice to see its back, with better performance.
History repeated, with refinement.
