It depends, I’m not sure if it’s a binning thing and they can’t make enough perfect chips for the 3090. Or it might just be limited memory, they’re using all the gddr7 that’s being made and that’s with many different suppliers.

There are some small regional places

It’s parallel unlike a CPU, so there isn’t anything inherently wrong with just scaling the chip up in size and power. It just makes your room hot if you have the xx90 on at full blast for hours.

F35 is guaranteed to be better than a “6th generation” Chinese plane and they can be upgraded anyway. And it’s actually very successful now with a very cheap per plane cost.

It’s more about sensors and communication, there’s no reason you can’t have f35 use drones and stuff. But the better plane will see and target the enemy first. And it can operate without GPS. In other words it’s better to have 3000 f35s flying missions plus a bunch of drones. Being able to deliver a lot of firepower first is a huge deal.
