Nope. These are new SKUs (LHR variants), not a patch that retroactively applies to existing stock/sales. If anything, so long as crypto demand persists, this will result in a upward influence on the scalping price of the currently existing non-crippled 3070's and 3080's. Technically Nvidia has existing mining SKU's (their HX skus) so new supply is still entering the market, but its unclear exactly how things will balance out. In the short term (assuming demand remands high for crypto cards), I'd expect scalped pricing to go up, not down. And that's assuming these LHR's arent compromised like the original mining-crippled 3060's have been.

I think it's less about the upfront cost and more about hashes per kilowatt-hour.

Ah that makes sense, I forgot about power usage.
