So far Nvidia has always thrown the highend models to the market first. Mainstream was always out later, so I have my doubts about this source. Not saying it's completely bs, but things may be different.

One thing is wrong for sure: The memory speed is surely not 2000 MHz, because that would mean DDR4000 The correct value should be 1000 MHz or DDR2000, but not 2000 MHz.
