Intel’s new Optane technology is divided into two segments, bridging the gap between DRAM and storage. In the storage product, we’re talking about a competitor to 3D NAND, but at low capacity, high-performance storage layer that uses NVMe. In the memory product, this is in the DDR4 form factor and offers a high-capacity slightly slower alternative to DRAM. With Intel’s new Cascade Lake processors, it now supports the new memory DDR4-compatible version of Optane.
Intel promotes Optane DC Persistent Memory (the official name) in two ways.
First, as a way to add much more memory to the system at a slightly slower speed. With the high-memory compatible processors, users can add up to 3.0 TB of Optane DCPMM to 1.5 TB of DDR4, to give 4.5 TB of total memory per socket. In this configuration, the DDR4 acts as a buffer/store in front of the Optane, which hides some of the increased latency, but ultimately it means that larger in-memory databases can be used per socket.
Secondly, as a persistent memory store. The number that Intel likes to quote here is when a system restarts and needs to reload all of its data from NVMe into main memory. With persistent memory, the data is already there, like a storage device, and as a result it can reduce downtime from loading the database from forty minutes down to four, which for a warm reboot reduces the downtime quite considerably.
The 48C per socket means there are two chips in an MCM, XCC dies wired together via QPI links. The inter-socket links are not specified but they are likely not fully connected dies, think a square not a square with an X in the middle. In any case these monsters will be 350W meaning their TCO will be quite questionable in all but a few markets. The new socket plus the near absolute requirement for water cooling will relegate them to a niche for the reasons we described earlier.
I'd like to know how they will get customers to purchase these. They are the epitome of a stopgap.
Worst part was I was watching it and it was at 50-75 cents or whatever at the time LOL
we'd be millionaires by now T_T
I was watching it all the time back then too, and I knew it was going to go up a lot for sure. Only other option was for AMD to go bankrupt at that point and that seemed pretty unlikely. I was just a bit too young with my saving back then to have comfortably started a stock investment account but good god I wish I had followed through.
I even went as far as to try to setup a Charles Schwab account with $500 only to learn I didn't meet some kind of minimum to buy stock or something, I forget what the hold up was but I was like 8 out of ten steps there and just didnt follow through. Kicking myself all the time for that one.

Well, it is a square with an X in the middle so they are connected, so there is one assumption he got wrong there. It is kind of hard to say until we see the benchmarks of specific workload 9000 series is intended for.
