I can't find CMP cards anywhere friend it's like they are even more scarce than other Nvidia cards e.g rtx2080, just go to amazon.com and try searching for a CMP Nvidia card the results won't bring you anything than normal gtx1660, rtx2080 etc
Because these video cards were sold out in large batches before the start of their production.
Take any analogs I wrote about if you want to mine now.
CMP video cards have a very small guarantee, do not have a video output, and their price is no less than their counterparts for gamers.
