Anyone good at maths? I need you

I’m trying to figure out what would the physical size of an RTX 4090 die if it were manufactured using 130nm, the same process used on the FX 5900 Ultra.

I imagine it will be staggeringly huge, but I’m not sure where to start with the maths.

5900 ultra was built on the 130 nm process with a die area of 207 mm² and 135 million transistors at a density of 652.2K / mm².

4090 has a die area of 609 mm² and 76,300 million transistors, 125.3M / mm² built on a 5 nm process.

Then you go and ask everyone else… lol

Interesting that there's less transistors on the newer card

There are many more on the 4090, billions.

Just out of interest, why?

Pure interest really. I recall reading something about a modern CPU being made on an old process node would have resulted in the size of a large car.

I appreciate the above responses a great deal!
