I have been watching 3dXPoint since it came out because the combination of (a) lower price than DRAM, (b) fits in a DRAM DIMM socket and (c) many more write cycles than Flash was very nice.

One of my employers has a load with a lot of fairly static cached data that we would like to read from DRAM because we want ~10 GB/sec reads. You can get this with Flash but we do write often enough that wear becomes an issue. So today we ship DRAM. 3DXPoint was cheaper per bit, but ...

The catch was that we'd need to buy SO MUCH 3DXpoint that the price/performance didn't work out.

I kept watching hoping that things would improve (for us) but not really expecting things to improve.

Now I can stop hoping.

I do wonder if there was a fundamental issue where Intel *had* to price this where they did and couldn't economically make smaller capacity DIMMs or if this was just a business decision.
