What is to stop people from doing the same here in the west? Chinese factory's disassemble 4090 and repurpose for AI GPU. (alien.top)

Here is the link.

I can see people buying GPU, send it to Mexico, and do the same, then export the chips to China. Since China is already offshoring their production to Mexico, the logistic chain is already there.

That’s why you don’t see 384

2080 Ti, 3090, 4090.

or 512-but memory bus anymore

We haven't seen them since we moved to GDDR6. Simply because the signal integrity and power requirements makes it quite unreasonable.

find other ways to make up the performance for games

Lack of DRAM scaling is the reason why we are where we are. Computational power has grown much faster than bandwidth.

Nvidia has had around a generation of advantage in bandwidth efficiency/utilization since Maxwell over AMD. Surprise surprise, one generation after AMD they as well have to resort to larger caches to substitute for bandwidth.

A 512 bit G6 bus (which isn't realistic to begin with), would not have given 4090 enough bandwidth over 3090. To keep up with the growth in computational power.
