That’s because the type of jobs handled in a big internet data center are very different from the workloads that server memory was designed for. With traditional software applications, a chip swaps data with memory so quickly that it can use up more than 100 GB per second of bandwidth. But things are different over in the web data center. Companies like Facebook and Microsoft like to fill server memory with as much data as possible so they can return search results or timeline updates as quickly as possible. And that means that the chips don’t access memory nearly as often.
Interesting but sort of obvious.... most big data servers are just for caching. There is always stuff in memory but it's only read and only ocassionally written.

Surprised Google has not already gotten Intel or AMD to implemented LP DDR controllers in custom chips...
Once again...
