The idea is not to count on a wire.

What if there is a clog (e.g. from a failed hose liner) or a crimped hose and brake pressure doesn't release when it is supposed to? It used to be the job of the man in the caboose to know that. Now it's FRED's. It's also his job to detect over pressure or failing pressure that will stop the train at a potentially inconvenient time if not addressed.

It would be nice to have both a wire and a wireless connection, but one of the ideas was clearly to avoid needing another connection between cars.

I have it on good authority that Ferraris are faster than Civics, and therefore there is no market for the Civic.

That is an offtopic response, because the discussion is not about whether anyone will buy Chinese GPUs. It's about whether Chinese GPUs can be competitive for scientific computing. Whether they will ever will be or not, they are not now, which we know because they are still hungry for our hardware. And we can reasonably believe that to be true and not merely propaganda both because of sales, and effort spent redirecting purchases through other nations.

In the really real world, efficiency matters. If you need more nodes then both your up front and ongoing costs are higher as your system takes up more space and uses more power. Even if China can design a GPU as well as Nvidia (let's go ahead and assume that they can; I think they probably can soon, if not already) that won't make their performance per watt as good unless they have it fabbed by someone with superior process technology.

Indeed, ten times more powerful than NVidia.

I'm not clear on what you're claiming here. If the article is worth anything, which I don't take for granted, what it says is that they got a speedup for a specific workload by organizing their system with more GPUs per node. That would give a speedup for their workload no matter whose GPUs they used. The article doesn't claim it has anything to do with the performance of their GPUs.

China is working on 5 nm semiconductor production. The yields are too low, but they'll work out the kinks.

You could say the same thing about Intel.

But that's not an endorsement of the idea that China will succeed, and the point isn't even to bag on Intel, although that's fun.

ASML is a multinational company. The technology needed to do modern photolitho required the efforts of multiple nations to create. Why should we believe China can do it alone when so far, no one nation can do so?
