Internally, there are 28 variants of the GeForce RTX 3060/3070/3080 mobile

In recent years, it is not a problem to buy two laptops marked with the same name of the graphics card, while the two cards with real parameters differ so much that one offers more than half the performance of the other. This situation was accentuated when Nvidia split mobile graphics cards into 2017 with Max-Q with lower clock and power consumption and standard (Max-P) with higher clock and power consumption. As early as 2018, laptops with low-cycle and low-power cards began to appear, but without the Max-Q label.

So you could buy a notebook with the GeForce RTX 2070, which, however, achieved significantly lower graphics performance than the older generation GeForce GTX 1080. At the same time, this GeForce RTX 2070 did not offer extra performance compared to the GeForce RTX 2060 from the same generation.

This situation continues because, unlike 2017, when Nvidia clearly stated how the classic version of the mobile card and Max-Q differ, it now lists one specification for the GeForce RTX 3080, one for the GeForce RTX 3070 and one for the GeForce RTX 3060. consumption also has a possible range, in the latter case it is almost twice the range, and the user does not know from the name of the card whether to offer him 40 FPS or 60 FPS.

The reason why Nvidia lists one specification and not the specification for each model is that there are not two models for each of the three cards, but there are 28 real models:

VideoCardz table, for desktop GeForce RTX 3060 Founders Edition there is a typo in the last column (should be 10.1)

As is clear from this list, it is not a rule that slower / more economical cards must be marked as Max-Q. Conversely, the standard version may be slower than Max-Q. For example, on the sixth line from the end we see the GeForce RTX 3060 Max-Q, which achieves 8.1 TFLOPS, and on the second line from the end, we see the GeForce RTX 3060 (without Max-Q), which reaches only 6.9 TFLOPS and is therefore slower.

So even if the laptop manufacturer honestly states in the product description whether or not it is a Max-Q, you do not have a chance to know from the name of the card how fast the model will be.

As the editors of the VideoCardz website point out, we cannot rely on the fact that I will estimate the performance according to the mentioned TGP, as most manufacturers no longer state in the parameters of notebooks with GeForce RTX 3000 TGP:

So either the user has to choose the specific configuration that was used in the review (from which he knows what performance the used version of the card offers), or he risks buying a hare in a bag. Respectively, the payment for the performance of the GeForce RTX 3080 and the delivery of the performance of the GeForce RTX 3060. As can be seen from the table, both of these solutions can acquire a performance of 10.7 TFLOPS.
