Nvidia RTX 3000 - Mobile graphics chips: Performance now even harder to assess...

[09:52 Thu,28.January 2021 by Rudi Schmidts]

With the new generation of mobile RTX 3000 graphics chips Nvidia has given notebook manufacturers a wide variety of models. However, not necessarily to the advantage of customers. Because while the designations "MAX-Q" (throttled, or consumption-optimised) and "Max-P" (high power consumption, a lot of heat dissipation) have so far been used to a certain extent, they have not yet been used. (high power consumption, a lot of waste heat, high performance), it seems that these designations will be dropped in the future.

We, too, have stood head-scratching in front of test devices of the last generation, where the speed of the GPUs differed (significantly) despite similar type designation www.slashcam.de/artikel/Test/Gigabyte-AERO-17-HDR---Flaches-17-Zoll-Notebook-mit-4K-HDR-Display--Performance---Fazit.html .

In fact, Nvidia now gives the manufacturers even more leeway in how they enable or throttle the cooling and thus the performance of the installed GPU. This leads to the curious situation that a mobile RTX 3060 can be faster in some scenarios than a much more expensive mobile RTX 3080, for example when the

RTX 3060 is allowed to work with 125 watts peak power, while the RTX 3080 has to work in an 80W frame.

There is nothing surprising about this per se, except that it will now be even more difficult for users to find out how much maximum power the GPU in the laptop can work with. And, of course, how long it can be operated at high performance on a sustained basis.

For video editing, the speed of the connected memory is still a good indication of the expected performance of the GPU. However, many laptop manufacturers are silent on whether the connected DDR6 memory is also throttled...
