The PS5 hardware is essentially identical to the AMD BC-250 mining rig, with the major difference being that the media engine (VCN for encoding/decoding video) is disabled in the miner because it requires Sony's proprietary bios. The BC-250 was created from binned chips that didn't meet Sony's specs and had 2 of 8 cores disabled, but many users successfully re-enabled them and bumped active CUs on the GPU from 24 to 40.

To your point, it was briefly possible to buy them for under $100 until word spread that they make decent steam machines, so I'm guessing that Sony doesn't need to sell any games to turn a profit. Even at their current prices it would be far cheaper to use the BC-250 for local inference.

I don't follow your logic. If the BC-250 was made from PS5 quality control failures, then why would their pricing have any bearing on the PS5's profitability, except as an effort to increase margins? Does cost not remain independent of pricing?

As far as I cam infer from what you said, it could be that the PS5 was sold at a loss and still is even with the BC-250 helping, or that it was sold at a profit and is still is with the BC-250 helping. What am I missing?
