Nvidia's invincibility in mobile consumer gaming graphics has allowed it to do whatever it wants. Since removing the "M" suffix from the 10 series, Nvidia aims to close the performance gap between desktop and mobile graphics models. Level 60 graphics cards use 107 small cores, a thing of the "960M" era.
Nvidia has always been on the wrong side of consumers, and its only conscience on mobile was the 10-series. Dessert card 1060 beat the previous generation flagship card "980M". And the Fever 1070 beats the desktop in Clevo and MSI's 180w vbios.
With its 20-series graphics card, Nvidia may want to prevent this. So the 2070S use TU104 cores, but the power is locked at 115w. That only makes a 10% difference between the 2070S and 2070. In the 30-series, Nvidia limited the 3080 and 3080TI to 150w (Without DB), making the 3070ti 3080 3080ti only slightly different, and making the desktop 3070 almost capable of beating all mobile graphics.
Now Nvidia is shitting its consumers. The core of the mobile terminal is degraded compared to the desktop, and the power consumption is far less than that of the desktop. Desktop 4070 will continue to beat all mobile graphics cards.
