Intel "Cascade Lake" Xeon Scalable Chips to Support 3.84 TB of RAM per Socket

Intel is giving finishing touches to a new wave of Xeon Scalable processors based on its new "Cascade Lake" silicon. One of its first parts is a 28-core chip with a 6-channel DDR4 memory interface, support for 3 DIMMs per channel, resulting in 18 DIMM slots per socket. Its integrated memory controllers support a theoretical maximum of 3.84 TB of memory. The best part? The memory needn't be DRAM-based.

With its next-generation of enterprise processors, Intel is introducing support for Optane Persistent Memory. This 3D X-point based memory module has a performance footprint between NAND flash SSDs and volatile DRAM; while being close enough to the latter to work as primary memory. Its USP is persistence - the ability to not lose data after power loss or reboot; allowing large data centers to quickly power down/up nodes in response to load, without wasting several dozen minutes in repopulating DRAM with data from a hibernation image. Optane Persistent DIMMs come in capacities of up to 512 GB. This is simply 512 GB of 3D X-point memory wired to a special on-DIMM controller that interfaces with standardized DDR4 interface.

hopefully they make a coffee lake - X for the x299 now that the x399 is looking like the next socket.

Well, I can only see "lakes"... but who cares? Epyc is... EPYC!

Intel continuing to be super disingenuous by implying that Optane is equivalent memory to DRAM.

I remember the rambus marketing... 800 MHz ram! OMGZ! But the bus was far slower than PC133. It was also incredibly expensive and red hot. After Intel got destroyed by AMD, they had to quietly switch to regular ol PC133 for performance uplift.
