It will affect some of AMDs last gen production and Nvidias GPU side IIRC?
Yeah, AMD's 16nm XBoxOne and PS4 chips may be affected, and pretty much all of Nvidia's 12/16nm GPUs, depending on what they were running in the fab at the time.
AMD's 7nm stuff is fine, and most of AMD's 14nm is made at GlobalFoundries.
Nvidias year starts as bad as it ended...
I wonder if cards that have already been shipped to distributers are affected by this - we could end up seeing some high fail rates with the early RTX cards
I've already had a Zotac RTX 2080 Ti Amp that failed within 2 weeks. Obviously could just have been a random failure but ?Quote:

Can't see it having much, if any effect tbh
This sounds to me like TSMC were relying on the supplier's own quality control instead of implementing a quality control at the fab. I wonder if there will be a big change in the way things are processed from now on, especially as chips become ever more complex.
It's 10,000 wafers, of which each will provide hundreds, if not thousands, of chips.Quote:

Probs looking at 7-10 days of production. Not sure if it'll have much of an affect, as it's also spread over 14 different customers.
How long does it take to get machines back up to temperature, or for certain chemicals to be purged from systems? Things like that. This could have a much bigger knock-on effect than we realise.Quote:

Shhhhhh! Don't give them ideas!Quote:

Not if the bulk of affected wafers are Turing dies.Quote:
