You're seeing the effects of the HBCC. Able to micro-cache rapid read/write cycles so massive datasets don't get huge bottlenecks by the 16GB VRAM.
The HBCC obviously doesn't care where the data is stored, in RAM, NVMe, SSD, even network. But it's important to have the capacity to store the dataset first.
By using a 2TB NVMe, AMD can offer more total capacity than most workstation's system RAM. 2TB is something typically seen only on the very high end 2 socket servers.
AMD wasn't joking around when they demo these 8K vid editing and live ray tracing scenes with hundred of GBs of high-res texture/model assets, in real time.
It's also features like this that AMD needs to push into the pro market, they have to be able to do stuff that NV GPUs cannot.
