From Wikipedia
"Moore's law is the observation that the number of transistors in a dense integrated circuit doubles about every two years."

That's just... insane. That's five transistors for every person on the planet. In 700 mm2.
[Edit: And a number that people have some intuition of how big it is.]
An impressive feat for sure but it is just using brute force to increase performance nowadays.
GTX 1080: 42.81 mm^2 per billion transistors. 41.53 mm^2 per TFLOP. 0.97 billion transistors per TFLOP.
RTX 3080: 15.55 mm^2 per billion transistors. 33.17 mm^2 per TFLOP. 2.13 billion transistors per TFLOP.
They scale well for transistors against die size, and TFLOP against die size, but terribly in transistors per TFLOP? That can't be right.
Checking https://www.techpowerup.com/gpu-specs/geforce-rtx-3080-ti.c3... I now see it says "Based on speculation / placeholder", which makes me think it's all just totally made up, and not reliable evidence to declare the death of Moore just yet.
I could design you a chip that is nothing but FP32 multipliers and adders that has, theoretically, a ridiculous TFLOPS per mm^2, but it would be next to useless in any real workload.
