I didn’t see a release date for GDDR7 in the article, so I’m guessing we’ll see the first version of it being used for the next wave of GPUs after this generation, so likely 2024. I also doubt it launches at those advertised speeds. I’d guess more like 28-30Gbps for the first version, but I’d love to be wrong.
Still, it’s good to see GDDR7 get announced. Memory bandwidth has definitely been in short supply for GPUs the last couple years, given the increasing reliance on cache to bolster effective bandwidth in the absence of big speed increases in memory itself.

It's not 1000 etch cycles like you think of. It will be 1000 layers of the (if I remember correctly) word lines/bit lines stacked up. The cells are vertical columns that run through the whole staircase. They etch the columns for the NAND cells and the staircase for landing contacts differently. It'll be a lot of etching, but not one per layer like you're picturing. It'll more likely be multiple decks of etching.
I'm a little rusty at this, though. I was mainly a DRAM guy.

I wouldn't say that HBM never went anywhere; it was a high bandwidth, high latency alternative to GDDR's (relatively) low bandwidth, low latency, which was achieved by essentially overclocking the interconnects in GDDR, leading to HBM being much more power efficient. And then they overclocked their Vega series through the moon, but anyway...
...HBM is still alive and well, but it's more commonly used in server and workstation applications ATM, where bandwidth is worth as much as the compute in the right workload. We might actually see some high end gaming GPUs in a year and a half to two and a half years here, as certain incoming trends in game rendering (raytracing, machine learning, and so on), can benefit from increased bandwidth, though at least on the AMD side I think they'd prefer to do 3d stacked cache as beyond having a higher effective bandwidth, it also basically improves the perceived latency, and power efficiency is more heavily improved than via using HBM.

Question, what stuff asides from GPUs and game consoles uses GDDR? As a consumer ot seems like these technologies only exist for those things. But clearly more stuff must use it right?

1000 layers. Does this means that it has to be lithography-etch lithography-etch 1000 times? That’s insane. Is that cost feasible?

Consoles also use only GDDR, there's n DDR in them.

To head off the “but we barely have DDR5” comments, the G is important here. This is memory intended for use by graphics cards and GDDR6 has been a think for years now. AMD tried to move the industry towards a new standard called High Bandwidth Memory with their RX Vega products but that effort never got anywhere

It might lower prices if they offer something compelling though so unless you need a new GPU now, there's no harm waiting a little.
