Searching for a LHR card found no real deals for video cards as miners are buying them regardless and trying to get around the restrictions. I have seen some comments about LHR cards in the NVIDIA forum and the miner with 10 cards was unhappy at the earnings. The questioner did not provide the specific models of card so it’s impossible to ascertain what had.

It seems that the mining has dominated thinking and gaming is dismissed in favor of corporate profits. Google showed several cards as women’s cards which suggests some real misogynist vendors out there. This table shows the part numbering scheme used by various vendors.

The AIB vendors have some coding to part number so the gaming community can select a card unlikely to be abused by mining extremists.

AsusLHR Cards will be marked with V2. Like “RTX 3070 V2 ”
EVGALHR will be marked along with the SKU as “KL” or “KL”+”LHR”
GigabyteAorous Rev 2.0 might or might not be LHR versions
MSILHR will be marked along with the SKU (ex – 3070 GAMING TRIO PLUS 8G LHR)
ZotacLHR will be marked along with the SKU (ex – RTX 3080 Trinity LHR or ZT-A30800D-10PLHR)

There are two generations of LHR cards known. One is driven by the driver which is easily circumvented. LHR also varies from coin to coin making it almost impossible to make a universal solution.

ErgoYes (Around 40% Reduction with some ups and down)

With the release of NBMiner v39.0 and above, the mining software has finally cracked the LHR wall that limited the mining potential to almost half of its limit. With NBMiner, you can now unlock up to 70% of ETH performance on the RTX 30 Series. It is likely NVIDIA will take additional steps as they discover how to block all mining. Many mining operations are using Linux as well which makes it harder to block mining.

Market prices for Radeon RDNA 2 cards has risen 9% in November 2021 while in October the cards rose about 6%. Valuations are driven by mining considerations based on recent NVIDIA LHR steps. Evidently Ethereum is still best mined on the old Polaris cards. On average RTX 30 cards on fleabay are 113% more expensive than MSRP and gained 6% in value since October. Pricing for LHR cards is slightly lower than unnerfed cards.

Prices for core personal consumption expenditures increased 4.1% from a year ago, the highest since January 1991. Along with the surge in prices came an increase in the amount consumers spent, which rose 1.3% for the month. Video card pricing has so far not been affected by inflation as the perceived values are how much it can earn.

Come 2023 the supply of new video cards should be substantially better. What effect it will have is likely to see mining grab even more cards as they chase profits. Many smaller mining operations reinvests earning to buy more and more video cards. It’s a vicious circle that means gaming is now a fading memory.
