Given the history of prohibition in the past few centuries, it wouldn't surprise me if it is much easier to buy Nvidia products in China than in the US. The price is much higher most likely, but the actual transaction is likely easier.

Unless the US somehow differs from the EU in some major ways, can't you just walk into a store and buy a NVIDIA GPU? Not sure how much easier it can get. And yes, it's as easy in China to, walk into store, point at GPU, fork over the money, you get your GPU. Like everywhere else, except the US I suppose?

Yes and no. Yes, you can still buy high-end prosumer Blackwell hardware at retail in the US, but not without going through a KYC process that didn't exist a couple of months ago. The writing is on the proverbial wall.

In China, you can give them a 4090 and have its ram doubled to 48GB with custom firmware, so yeah, pretty much.
