Rtx 3070, 3080, and 3090 outperformed all other graphics cards in the market. Nvidia was almost about to set a benchmark for other graphic card producers with RTX 3000 series, but now we came to know that the card will not be in the market this soon until the start or mid of 2021. Nvidia launched RTX 3000 series to compete with AMD's Navi 21 Radeon RX 6000 series. 

Rtx 3000 was about to come in variants of 8 GB, 10 GB, and 16 GB with GDDR6X. Nvidia shouldn't have released the cards this soon if they weren't prepared the problems were caused because the production team was unable to produce the many cards that people demanded so the company made it go off air from the market as Nvidia CEO Jensen Huang stated "demand will outstrip all of our suppliers through the year", this means the card will not be available till 2021. Micron is the only company that produces this so the production line just got limited and the production system is marked as poor. Now it seems like the card will be part of a substantial refresh in 2021.
