the title is doing the heavy lifting here. the paper discusses how they apply an existing standard (CXL), to provide an intermediate memory tier in a niche use case:

> Each MemServer combines 768 GB of DDR5 memory alongside 256 GB of DDR4 connected through Vistara ASICs.

while the ratio above would be nice the other way around, this approach surely adds enough latency to make it comparable to intel optane than system memory at face value.

this should not take away ddr4 supply for those who would like to run it at home.
