TSMC 4nm Production Hit By... A Full Quarter Advance? | TechPowerUp
 
Here's something that has been sorely missing from tech news: good news. It seems that TSMC's development on the 4 nm manufacturing process is running better than anticipated by the company itself, which has prompted for a full quarter advancement for the test production on TSMC's next miniaturization level. Previously scheduled for test production starting on 4Q 2021, TSMC has announced that it has now moved test production to 3Q 2021.

This could mean an equivalent - or perhaps even better - reduction in volume production and time-to-market, but it's anyone's guess at this point. As notably difficult and onerous as semiconductor development is, problems are more likely to appear than not. 4 nm is expected to bring respectable improvements to the PPA equation for semiconductors over 5 nm - however, TSMC still hasn't disclosed expected gains.
 
Great work by TSMC in my opinion. Die shrinks ahead of schedule is rarely heard of. 

Great news but I think most of the world is going to care about volume over advancement for the next couple years at least

It’s going to take many of these types of announcements to turn the tide. Supply has a long way to go yet to hit demand.

EVGA literally has nothing to sell on its web site save cables and keyboards. That’s just crazy.

Agree plus inflation and a slow down in everything...not looking good.

the plant they were planning to build in US won't be 4nm i think, probably will still be based in Taiwan

I think the plant in the US (AZ?) will be 14nm? iirc.
