Sunny Cove extends virtual addresses to 57 meaningful bits...The new limits enable 128PB of virtual address space and 4PB of physical memory.
This is interesting to me. At first glance I couldn’t really figure out “why now”. But I guess with Optane there really will be a need for addressing petabytes of ram, as it will span DRAM and Optane. It seems Intel thinks it will be a competitive advantage.
