You Gaming laptops Is an alternative for users who need more powerful computers but do not have the money to build a desktop with a high-end processor and GPU. For a long time, Nvidia and AMD have been offering mobile versions of graphics cards with more restrained specifications, but in recent years both have argued that there is no difference in functionality between a special notebook and its older sister.
Today, most manufacturers of gaming laptops like to brag about their product specifications, especially when equipped with the latest generation of GPUs, but the truth is that even sharing the name, there are differences in performance between desktop and laptop, and even mobile. Computers with similar configurations.
The issue of energy
The issue revolves around how much power the laptop consumes and how much is directed at the GPU, which directly affects its performance and its overall performance. The user on the desktop has a power supply that is powerful enough to make the dedicated graphics card work fully and can replace it when there are power problems.
A laptop, whether gaming or not, can not afford this luxury. The design of the mobile computer should take into account how much power the kit consumes and if it has a dedicated GPU, it is important to provide adequate power for optimal performance. This feature is measured in the total graphics power TGP, a feature that Nvidia has been requesting since May 2021 to include gaming laptops in the specification with their GPUs.
This was done to reduce confusion when purchasing a gaming laptop so that the user knows how much power the GPU consumes and what its real clock is, but after a year not everyone follows the practice, which has led to embarrassing situations. .
As of February 2022, Website Check the notebook Performed benchmarks between two different models of MSI gaming laptops, both equipped with the RTX 3070 Ti graphics card. In tests, the Stealth GS66 ran about 15% lower than the Vector GP66 3D Mark, even using exactly the same GPU.
One explanation for this is that the Stealth GS66 is thinner than the Vector GP66, so it consumes less power, so there are no overheating problems; The problem is that this reduction directly affects the performance of the GPU, in which it is not enough to just watch a model equipped with a laptop.
Web page Digital trends Conducted similar tests but using two laptops with remote GPUs. In terms of performance, the Lenovo Legion 5i Pro, equipped with the RTX 3070 Ti, scored nearly 2,000 points on the 3DMark ahead of the Gigabyte Aero 16 using the RTX 3080 Ti.
Again, it should be noted that the second is thinner than the first, which explains this inconsistency in performance. With less power supply, the video card will not achieve maximum performance and will not achieve the result
Gaming laptops, TGP and specifications
As mentioned above, Nvidia has started asking manufacturers to explain on official websites their product specifications, how much power the GPUs in gaming laptops consume, but most OEMs completely ignore the manual or beyond the confusing pages and links.
For example, Dell publishes information about video card TGP and power consumption on a separate page, which is available in the product settings with the “Help me choose” link when it should be open.
It should be noted that Nvidia is in favor of greater clarity, but is not entirely clear. Recently, the company abandoned the Max-Q and Max-P designations for its GPUs, which first focused on cards that consumed less power, i.e. had lower performance than the Max-P is classified.
Keep in mind, however, that ending the nomenclature does not mean abandoning the practice. It just made it harder for the user to determine which gaming laptop is more powerful, even among models that use the same GPU and have reached situations where the theoretically weak are better than the high-end.
In an ideal scenario, manufacturers should clearly and succinctly show how much power their GPUs in their laptops consume so that consumers can decide which model to choose. The design, which facilitates ventilation, even offers a larger and heavier body, has a good chance of delivering more power to the video card, thus being able to work 100%.
Clearly, all OEMs want to sell and with the possibility that their product is out of competition, even using the same GPU, they prefer not to mention TGP and watch and energy specifications. The end of Nvidia’s Max-Q and Max-P nomenclatures also helps them in this regard as this has added to the confusion.
At the end of the day, the best option for those who want to play computer games at maximum productivity remains to build a sophisticated desktop, but those who do not throw a needle for it will have to go through a lot. Rocky way to find a laptop that fits your needs and that your video card does not work 70% because it does not get enough power.
