A card with a 115 W TGP is on average 11% more efficient in about twenty games than with an 80 W TGP.
Since yesterday, manufacturers have offered notebooks equipped with an NVIDIA GeForce RTX 3060 mobile graphics card; And as mentioned in a previous update, there can be significant performance disparities based on the card’s TGP. In fact, NVIDIA leaves plenty of room to configure it, ranging from 60 to over 115 W for the RTX 3060. The Techspot site has tested the benchmark in several games, including Control or Red Dead Redemption 2, with TGP (Total graphics power) different: 80 W and 115 W.
Therefore, Tim schiesser mobilized an XMG Apex 17 laptop available in two configurations. The former is armed with a Ryzen 7 5800H processor and an RTX 3060 set to 115W; the second, an Intel Core i7-10870H processor and an RTX 3060 set to 80 W. Naturally, the processor has an impact. To counteract this bias, TechSpot mainly tested more demanding titles with the graphics card than with the processor. Therefore, the site indicates that in most cases, the GPU is the limiting factor. Finally, keep in mind that laptops benefit from the Max-Q Dynamic Boost feature. This is likely to give an additional 15W of power to the GPU when the CPU is not heavily used.

An 80W RTX 3060 equivalent to a 90W RTX 2070 Max-Q
In terms of overall performance, the RTX 3060 at 80 W is 19% higher on average than an RTX 2060 at 90 W. Specifically, it is on the level of an RTX 2070 Super Max-Q at 90 W in Full HD. However, with one notable exception, Cyberpunk 2077 with ray tracing (the RTX 2070 Super has 36 RT cores, compared to 30 on the RTX 3060).
Between an RTX 3060 at 80 W and one at 115 W, TechSpot reports an average performance gap of 11%. However, there are big differences between the games, including Gears 5 and Metro Exodus.
Unfortunately the RTX 3060 set to 60W has not been put to the test. The interval between this and a 115W model promises to be substantial.
