Intel’s Optane cache drives are not DRAM, but PC OEMs would prefer to think otherwise: in one example, Dell is selling a G3 15 laptop that lists 24GB of RAM. Closer inspection reveals there is only 8GB of actual (2666MHz DDR4) DRAM, however, as the other 16GB is Optane memory, which serves to “accelerate a conventional hard drive’s read/write performance in a manner that’s similar to using an SSD cache to perform the same task.”
Optane cache drives connect to their host systems via an M.2 port, which means they connect over the southbridge-attached PCIe bus. They are not attached to the system via its RAM slots like an NV-DIMM. They are not identical or equivalent to the Optane Persistent Memory DIMMs that Intel announced a few weeks ago.
