The amount of current that can be pushed through a thin silicon die is just wild.

I think of that every time I watch my GPU hit 440W sustained power draw on a die that is ~23mm square.

Which comes out to be about 831kW per square meter and the cooling solution keeps it at 60-63C even under that load (while noticeably warming my office since it's effectively dumping the same as one bar on a two bar electric heater).

As a species, we got really good at engineering.

I know nothing about your GPU, but it's probably at around 1V core voltage, so this is hundreds of amps.
Not far off, stock under full load is 1.15V (1150mV).
