Is Nvidia Quadro discontinued?

Yes this is very possible . But there is plenty of skepticism around the profitability of mining with an Nvidia quadro graphics card.

Is your Quadro P4000 actually idling and not doing any work? But it looks like it’s Pascal based comparable to GTX 1070 card, so you can probably use it to mine any equihash algo based coins like Zencash, ZCash, BitCoinGold, Hush .

The company confirmed to STH that indeed future products would streamline branding with the “Quadro” brand phased out as we saw the “Tesla” brand phased out on the data center side in 2019.
