I'm not convinced that allowing Intel to acquire GF is a good thing, but I'm not passing judgement either, without more facts.
I agree that NVIDIA acquiring ARM is a good idea though. Just think how fast those CPUs could go with NVIDIA accelerating them like Intel and AMD have with x86 / x64!
I don't think this is huge blow to AMD or anything; they can make their IO die or whatever else they plan on making with older nodes with anyone else. The only reason they were using GF is because they had to at least
try to fulfill some of their manufacturing contract. AMD only went to TSMC because GF coudln't get their 7nm node up and running, the long term goal in the beginning was to always use GF as their primary foundry source. That said having one less independent foundry can't really be good for the market in general.
Off topic but Nvidia buying ARM is not a good thing in my opinion. They claim they will keep the status quo in regards to licensing and that they won't keep the best stuff for themselves but why should anyone believe that and if thats the case why spend all the money in the first place. Anyone with architecture license can do whatever they want with the ISA and design their own cores, thats what all of Apple's CPU are. And don't they already have one?, I thought all of Nvidia's ARM CPUs were custom designs its just that nobody cares cause they are garbage compared to what Apple is doing.
But reading between the lines here, it does look highly likely that Intel cannot compete with AMD products, so instead they will just take the foundries away (taking capacity, or outright buying them) until AMD just has one place to go - an inferior process tech - A very smart way of putting AMD in a corner.
It dosn't work like that. Whatever contracts are in place now would have to be fulfilled, you can't just rip them up cause GF and AMD aren't besties anymore. Besides if it goes through it would take years happen anyway and AMD is only using GF for the IO die (and maybe future smaller CPUs and GPUs?). Capacity on older nodes isn't as contentious as it is on the leading edge ones so AMD could have 14, 12nm made wherever with a little bit of redesign work.
