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 mean, it's only 10,000 chips - their monthly output is probably much higher, perhaps even an order of magnitude more
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.
Ah, in which case, not good news
Just had a quick look, their fab has a rated monthly output of 100,000 wafers, so they'll have lost 3 days ish worth of production, and then an extra few days to account for resetting everything etc
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.
Fingers crossed it's nothing big, otherwise it's just another way for companies to try and bump price up artificially.
The thing is they *finish* 100000 wafers a month, but last I heard it was about 3 months from start to finish for a wafer to go through a line.
TSMC have got through much worse in the past, so I'm sure they'll have good recovery plans in place. But if customers are told they have another 3 months to wait for their orders to turn up after rebooting the line, that could really impact some products.
Bad Photoresist Costs TSMC $550 Million, ouch.
