Anyone good at maths? I need you

Assuming that the individual transistors scale with process (in reality they probably don't) means:

One 130um transistor be 26 times smaller on each side on a 5um process. So you would be able to fit 676 5um transistors in the space occupied by just 1 120um transistor.

so moving a die from 5um to 130um would make it 26 times bigger on each side or increase the area by 676 times.

So the 609mm2 die would then become 411684mm2 or a square about 64cm on each side!

my previous working is wrong, I scaled the 207nm die by 26, basically scaled the 5900 die size by 26. This is the correct answer.

Just out of interest, why?

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!

Probably would need the engine of a large car to run it as I assume that it would be 26 x whatever the 5900 pulls.
