and How much is that in terms of percentage of bitcoin network capacity ?

Bitcoin mining consumes about 25 GW: https://ccaf.io/cbnsi/cbeci so this single deal amounts to about 40% of that.

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.

I'm also wondering what kind of threat this could be to PoW blockchains.

Literally none at all because asic

		What happens if AI doesn't pay off before the GPUs wear out or are in need of replacement? So at that point a DC replaces them all with ASICs instead? Or if they just feel like doing that any time.

		Some chains are designed to be ASIC resistant.
