All die sizes are within 5mm^2. The poster here has been right on some things in the past afaik, and to his credit was the first to saying 505mm^2 for Navi21, which other people have backed up. Even still though, take the following with a pich of salt.

Navi21 - 505mm^2

Navi22 - 340mm^2

Navi23 - 240mm^2

Those aren't exactly mutually exclusive statements. It can still be horribly expensive to build. Like most blower style coolers, it seems most at home in tight cases without a lot of airflow. Reviewers OTOH are often using open air benches or enormous top end cases. JayzTwoCents did some testing on temp and found the FE actually making the CPU cooler, which is really weird.

Thoughts?
It is possible that a large 128MB cache could occupy 120-150mm2 of space (based on Zen2 estimate slices) .... so if N21 is 505mm2 that leaves a pretty small area to pack 80CU, no?

You mean other than it not achieving what he claimed, and there being no real reason for it to be much more expensive. It's custom design, but for the 3080 at least it has similar mass of aluminum and heatpipes. It should have similar production costs to AIB designs. 3090 cooler might be more expensive, by virtue of it's extra mass, but it's a $1500 card.

Not sure why anyone would bend over backward looking to give MLID excuses for the nonsense they post. He's consistently wrong and people keep coming back for more.

What's your take on the RTX 3070 delay regarding RDNA2?

1) Nvidia knows RDNA2 is not impressive and they are going to steal all the thunder after AMD presentation?
2) They know 3070 isn't very competitive vs RDNA2 and Nvidia wants to avoid comparisons on AMD slides?
3) They have no idea what the GPUs from AMD are like and how they perform (so they can cut the price if needed)?
4) It has nothing to do with AMD and they're just improving drivers and stock?

I think that is basically option 2, which seems very likely. Maybe NVidia has my Clock wiggle room for the 3070 specifically that it can use depending on AMDs competing part.

There is also the possibility that it identified a design flaw in the 3080 Crashing issue which it wanted fixed prior to the release of the 3070.

Or they are confident in its performance and expect to sell a ton even after RDNA2 announcement. If they knew it sucked in comparison it would make sense to launch it before. That way people would at least buy them. In any case, it's possible to interpret this in so many different ways...

They could delay it by a month and it wouldn't make a difference because it's a paper launch with 0 stock either way.

You don't move around launch dates like a headless chicken if you're confident in your product.

I wonder if AMD will show RTX 3070 results in comparison to RDNA2 on Oct 28. They will obviously have access to the release cards at that time.
Maybe Nvidias idea was to just prevent that by postponing the launch, but AMD is not bound by Nvidia NDA ...

Its very simple. If you have inferior product you have two choices.

Either you launch the product before your competition, or after, and adjust prices.

Its simple as that.

That some people read too much into every little thing, and need to have a conflict drama to go with it.

I am sure that if we read somewhere that Jensen was seen arriving 5 minutes late for work this morning, there would be theories that RDNA2 worries are keeping him up at night. Quickly followed by clickbait video detailing the RDNA2 nightmares he was having last night, based on confidential unnamed trusted sources from Huang household. :D

In reality he just saw a milk drool spot on his leather jacket and went back into the house to grab a new one.

I don't think there's a lot of wiggle room for Ampere and SS 8nm based on what we've seen so far from the 3080 and 3090. Once it hits the edge throwing another ~100W barely gets any gains.

All the wiggle room is in the other direction because cutting the voltage can drastically lower the power use while still keeping 95% of the power. I think that both Polaris and Vega have shown us that it really isn't worth chasing that last 3% performance when it makes the cards run that hot.

NVidia can spend a lot keeping a card like the 3090 cool with expensive custom cooling solutions because it's a $1500 card. It's a lot less financially viable if you have to do that with a $500 card.

I think Nividia has ensured that every RTX 3070 review is going to be comparing its real world performance (including everywhere it comes short of being "above a 2080 ti") against the likely cherry-picked marketing performance numbers from AMD's presentation; bad move IMO.
