The models’ strict specifications such as number of computing units, memory buses and graphics memory capacity correspond to the stationary variants of Geforce RTX 2080, RTX 2070 and RTX 2060. The difference lies entirely in the clock frequencies, which have been turned down so that the graphics cards can be used in laptops.

The top model is the Geforce RTX 2080, whose nominal clock frequency at GPU Boost is 1,590 MHz instead of 1,710 MHz in its stationary equivalent. In return, the TDP value drops from 225 to a slightly liquid 150 W +, which indicates that manufacturers have some leeway to increase performance and power consumption.

When the graphics card is converted to energy-optimized Max-Q Design, it drops significantly in frequency to 1,095 MHz at GPU Boost. At the same time, its 8 GB GDDR6 memory drops to an efficient clock frequency of 12,000 MHz, which reduces the bandwidth to 384 GB / s instead of 448 GB / s. The result is only 80 W TDP, which allows the model to fit in really slim designs about 20 millimeters in profile.

Next in line is the Geforce RTX 2070, which compared to its desktop sibling has a GPU Boost of 1,440 MHz instead of 1,620 MHz. This means that the TDP value shrinks from 175 W to 115 W, which makes it better suited for slim designers than full-scale RTX 2080 with its 150 W +.

With the addition of Max-Q Design, the RTX 2070 steps down further to 1,185 MHz and the GDDR6 memory receives the same treatment as the RTX 2080 Max-Q Design. Here, too, the result is a TDP value of relatively low 80 W.

Then comes the Geforce RTX 2060, which has not yet been released for desktops but whose specifications are known since before. The model’s GPU Boost lands at 1,200 MHz, compared to 1,680 MHz for the desktop variant. Consequently, the TDP value takes a proper step down from 160 to 90 W.

For RTX 2060 Max-Q Design, no major changes are required to dot the 80 W TDP, which seems to be Nvidia’s goal for energy-efficient graphics circuits for laptops. The model’s GPU Boost stands at 1,200 MHz while its 6 GB GDDR6 memory has a lower clock frequency, which gives a bandwidth of 288 GB / s instead of 336 GB / s.
