For someone who doesn't know what a gigawat worth of Nvidia systems is, how many high-end H100 or whatever does this get you? My estimates along with some poor-grade GPT research leads me to think it could be nearly 10 million? That does seem insane.
and How much is that in terms of percentage of bitcoin network capacity ?
To be clear, I am comparing power consumption only. In terms of mining power, all these GPUs could only mine a negligible fraction of what all specialized Bitcoin ASIC mine.
Edit: some math I did out of sheer curiosity: a modern top-of-the-line GPU would mine BTC at about 10 Ghash/s (I don't think anyone tried but I wrote GPU mining software back in the day, and that is my estimate). Nvidia is on track to sell 50 million GPUs in 2025. If they were all mining, their combined compute power would be 500 Phash/s, which is 0.05% of Bitcoin's global mining capacity.
