Its not so black and white. The A100 is exponentially more difficult to assemble even though it is older. The silicon is far more specialized. You pay a price for such a "fat" node and server hardware guarantees.

At the same time, the cost is outrageous. Its not a low volume product.

Also, a 48GB 4090 (or 3090) would be trivial. So would a 48GB 7900. Its not done for purely anticompetitive reasons, one that AMD and Nvidia are unfortunately happy to go along with.

48Gb 4090 exists already, just with a different name, branding, and pricing strategy: https://www.nvidia.com/en-us/design-visualization/rtx-6000/

48Gb 3090: https://www.nvidia.com/en-us/design-visualization/rtx-a6000/

It looks like the rtx-6000 costs around USD $10k. Quite the step up from the 4090.

I'm always surprised that people bring up cost as a main factor determining price, especially here on HN. Maybe it would be on a commoditized market with many competitors, which the GPUarket clearly isn't.

As most economics 101 lecture would tell you, price is determined by supply and demand and in this case Nvidia essentially maximizing their profit based on the demand and segmentation of the market.

Its not that simple, as Nvidia is supply constrained and technically not a monopoly. And they have to manage a gaming market and share supply from TSMC/Samsung with with other markets.

Is this why Intel started taking dGPU production more seriously in recent years?

There kind of are 48 GB 4090s and 7900s; they're just under different names.

Yeah, but Quadros (and the AMD equivalents) are outrageously priced too.

Nvidia and AMD used to "let" their manufacturers double up the vram on gaming cards, but no more. Its pure, collusive, anticompetitive market segmentation.

what names?
