The ASUS TUF Gaming F15 offers superior performance for 3D rendering, machine learning, and engineering tasks due to its powerful main processor and GPU, which make it well-suited for intensive gaming. It also features a larger screen and higher refresh rate, making it great for fast action games; however, it is heavier and has a shorter battery life, which affects portability. On the other hand, the Dell Inspiron 14 7420 is more portable thanks to its lighter weight and longer battery life. It has a higher resolution touchscreen with a different aspect ratio that might be preferable for general use and better webcam and portability scores. The Inspiron's performance for general tasks is comparable, but it may struggle with more intensive tasks due to a less powerful GPU. If the focus is on gaming and high-performance tasks and you can manage with less portability, the ASUS is the better choice; if you prioritize portability, battery life, and touchscreen capabilities for everyday use, the Dell might be more suitable.

The ASUS TUF Gaming F15 is very good for gaming and AI, while the Dell Inspiron 14 7420 is only fair.
The ASUS TUF Gaming F15 offers superior gaming and 3D performance mainly due to its high-end Nvidia RTX 4070 graphics card combined with a 144Hz screen refresh rate, which leads to smooth visuals in fast-paced scenes, while the Dell Inspiron 14 7420, equipped with an integrated Intel Iris Xe graphics and a 60Hz screen refresh rate, provides adequate but less-optimal gaming and 3D experiences. Additionally, the ASUS's GPU and screen refresh rate make it better suited for gaming, and the CPU and screen quality add to its capability, compared to the Dell which, while more portable, compromises on performance due to its lesser graphics capabilities and lower screen refresh rate.

The ASUS TUF Gaming F15 has a better screen than the Dell Inspiron 14 7420 for general use, gaming and AI, engineering and design, and content creation.
For general use, the ASUS TUF Gaming F15's screen offers better resolution and brightness, enhancing the visual experience for daily tasks and media consumption. In engineering and design, both laptops provide fair color accuracy, but neither excels in wide color gamuts such as DCI-P3 or Adobe RGB, which are critical for professional color work. For 3D and gaming, the ASUS falls short despite its gaming branding, as it lacks a high refresh rate that's key for smooth motion, and the display attributes like resolution and panel type are only moderately meeting the needs for these demanding applications.

How the ASUS TUF Gaming F15 and the Dell Inspiron 14 7420 compare to other laptops
"Aside from all the chassis updates, the new TUF Gaming is most notable for its much higher TGP target of 140 W compared to only 95 W on the previous generation. PC makers everywhere are using the same GeForce GPUs this year since Nvidia has yet to launch the successor to the mobile RTX 3000 series. The more demanding processors of the new TUF Gaming has directly impacted battery life and the size of the AC adapter. Don't expect runtimes to be longer than on the previous generation under most conditions and be prepared to carry around an even larger AC adapter than before."
"Notable qualities of the Inspiron 7420 2-in-1 include the 16:10 aspect ratio, strong hinges, 12th gen Intel CPU with optional GeForce MX graphics, and easy serviceability. Such features would typically cost hundreds of dollars more on higher-end alternatives from competing manufacturers. The value proposition is therefore relatively high for users looking to maximize bang for the buck."
