At the Consumer Electronics Show, Nvidia unveiled the new GeForce RTX 3000 Mobile graphics cards in addition to the RTX 3060. Notebookcheck claims that Nvidia partners for the new generation can determine certain properties themselves when integrating the RTX 3000 Mobile products.
For the mobile Ampere cards, of course, different SKUs are used with a fixed amount of cuda, rt and tensor cores, so it is mainly a flexible tdp. Other manufacturers like Intel do that too. Intel, for example, has its Tiger Lake-U CPUs set between 12 and 28 watts. This means that different cooling solutions in custom laptops can perform differently and will have a different load temperature than the model Intel itself tests with. An earlier review of Notebookcheck found that there is a significant performance difference between not only the different laptops from multiple manufacturers, but also between the custom models and the performance of Intel’s reference model.

The wider range of power consumption must of course be able to provide higher or lower clock speeds, and thus more or less performance. The RTX 3060 Mobile must have a tdp between 60 and 115 watts, according to an alleged table from Nvidia. The RTX 3070 has a range between 80 and 125 watts. The RTX 3080 must consume a minimum of 80 watts, but may also consume more than 150 watts. The reviewer states that an RTX 3060 Mobile at 115 watts should outperform the RTX 3080 Mobile at 80 watts in certain workloads.
That means the distinction between a Max-Q and a Max-P laptop will be less clear. Max-P stands for ‘maximum performance’, a term that laptop manufacturers use to describe the less efficient GPUs without Max-Q naming.
The other big difference that Notebookcheck mentions is a freer implementation of the new functions that the Ampere laptop models can use. Nvidia unveiled two AI-enhanced features called Dynamic Boost 2.0 and Whisper Mode 2.0 at CES. The former algorithm adjusts the boost clock speed of the CPU, GPU and video memory based on the purpose of use. Whisper Mode 2.0 adjusts fan speed in a more flexible way.
Manufacturers can choose not to integrate the software when developing overclocked laptops. Notebookcheck thinks that it will not be clear from a specification list which laptops will use these functions.
