Given how larger non-mobile chips are jumping to the LPDDR standard what is the point of having a separate DDR standard? Is there something about LPDDR5 that makes upgradable dimms not possible?

This is interesting. So without actually targeting a specific Cloud / server market for their CPU, which often ends with a chicken and egg problem with HyperScaler making their own Design or Chip. Nvidia manage to enter the Server CPU market leveraging their GPU and AI workload.

All of a sudden there is real choice of ARM CPU on Server. ( What will happen to Ampere ? ) The LPDDR5X used here will also be the first to come with ECC. And they can cross sell those with Nvidia's ConnectX-7 SmartNICs.

Hopefully it will be price competitive.

Edit: Rather than downvoting may be explain why or what you disagree with ?

Reading this makes a veteran software developer want to become a scientific researcher.

Way too late for me. I think adding machine learning to my toolbox at least gets me knowledgeable.

When Jensen talks about Transformers, I know what he’s talking about because I follow a lot of talented people.

It's theoretically possible, but there's no standard for it.

How likely is it that one of AWS / GCP / Azure will deploy these? Nvidia has some relationships there for the A100 chips.

AWS has their own CPU. Microsoft is an investor in Ampere, but I am not sure if they will make one themselves or simply buy from Ampere. Google has responded with faster x86 instances, still no hint of their own ARM CPU. But judging from the past I dont think they are going to go with Nvidia.

That is only the CPU though, they might deploy it as Grace + Hopper config.

AFAIK the higher speed of LPDDR is directly because it avoids signal degradation caused by DIMM connectors.
