I think there is a typo in "1000 amps of current."

  for desktop GPUs 1000 is bit much, but 600-700A are totally doable under LN2

    I think people are conflating watts and amps, watts measure power, amps measure flow. Watts = amps * volts. High power usage with low voltages results in high amperage.

      Even so, in this very case the amps are higher than the watts(!) as the voltage is below 1V.

      If Vcore is near 1 volt, then the magnitude difference between amps and watts is pretty small for the sort of discussion we are h aving

  No, a modern GPU literally draws about 1000 amps of current. For example, a non-overclocked 3090 draws about 500w under load (some of this goes to memory, but that is powered by the motherboard not by the external power connector), at a Vcore of roughly 1.1v which gives a bit over 450 amps--on average! The peak power consumption (as measured on a nanosecond scale being consumed by the asic itself) can easily be double the average power consumption due to the bursty nature of asic power draw.

    Remember that it's not just one core - that's what makes a GPU so powerful. My understanding is it's hundreds or thousands of 1.1v cores, which adds up to the 500w. EDIT - wait, what GPU draws 500w? I can't find one.

      Not sure any base cards draw this much. But might be doable via modding: https://www.notebookcheck.net/The-NVIDIA-GeForce-RTX-3090-may-have-a-350-W-TDP-but-it-can-consume-nearly-60-more.494757.0.html https://www.notebookcheck.net/The-NVIDIA-GeForce-RTX-3090-ma...
