Anthropic, OpenAI and Google are the standouts, but the main question for me is, why is this a war? In their own context China has greatly benefitted from this. They shored up their gpu design and manufacturing expertise. If this really is a war, trump is kneecapping the country with his lawlessness and eroding America’s good will. If the world cannot trust China with their data and they cannot trust the U.S. to prov…
The first consumer NVidia GPUs with similar FP32 FLOPS performance were in about 2011-2012 but were expensive. By 2016-2017, the 1060 was a very accessible consumer card with similar performance. So you're looking at about a 10 year lag from best consumer GPUs to a GPU with similar performance to a modern phone.
This is what people are spending trillions on. Put another way, their investment is going to be worthless in 10-15 yyears, absolute max. That's a very short time to recoup trillions in investment.
Obviously this depends on further shrinking and improving chips but I'm old enough to remember that same discussion and it being unknown if the future was XIL or EUV or if both of these would fail. Still, we are getting down to a handful of silicon atoms wide.
But the future here I think will be in interconnects so you don't need ever-bigger chips and you can scale horizontally much more effectively.
Oh and for comparison, the M5 has ~4.2 TFLOPS and the M5 Max has ~18 TFLOPS, for comparison.
As for it being a war, of course it is. That's what the US government does: it protects the interests of US companies and their owners. Look at the history of Bombardier-Boeing or all the atrocities committed in the name of the United Fruit Company, including multiple military coups and the ongoing embargo of Cuba.
US companies want an AI moat. China doesn't, ergo China is the enemy because no moat destroys US tech company value.
