The Lenovo LOQ 16 is good for gaming and AI, while the Dell Inspiron 15 3511 is only fair.
The Dell Inspiron 15 3511 has an integrated graphics chip less capable for gaming compared to the Lenovo LOQ 16 which features a dedicated Nvidia GPU better suited for graphic-intensive tasks and also offers a higher screen refresh rate for smoother imagery. Additionally, the Lenovo has a slightly higher resolution display, enhancing screen quality, while both boast modern CPUs which contribute to overall performance, although the Dell has more RAM which could be advantageous in multitasking.

The Lenovo LOQ 16 and Dell Inspiron 15 3511 are both good for engineering and design, though the Lenovo LOQ 16 is somewhat better.
The Lenovo LOQ 16 is very good for engineering and design due to its powerful AMD Ryzen 7 CPU and dedicated Nvidia RTX GPU, offering strong performance and high-quality visuals for computational and graphical tasks. Meanwhile, the Dell Inspiron 15 3511, with its Intel i5 CPU and integrated graphics, is considered good, offering solid performance for engineering applications but less graphical power than the Lenovo, making it more suitable for less demanding design work.

The Lenovo LOQ 16 has a better screen than the Dell Inspiron 15 3511 for general use, gaming and AI, engineering and design, and content creation.
The Dell Inspiron 15 3511's screen quality suffices for everyday tasks due to adequate resolution and brightness, but it lacks the wider color gamut essential for accurate color representation in engineering and design, and its modest refresh rate isn't ideal for the fluid visuals demanded by gaming or 3D modeling. The Lenovo LOQ 16, with better overall screen quality, provides an enhanced experience for general use and creative work thanks to superior brightness and color accuracy, yet it still falls short for gaming and 3D applications because of a lower refresh rate that can't deliver the smooth motion performance gamers seek. Additionally, the panel types of both laptops could impact viewing angles and color consistency, which are crucial for professional design work but less so for general use and gaming where direct, front-facing views are common.

PCMag
Zachary Cuevas | November 2021
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."

"Gaming laptops with an RTX 4060 are available starting from about 1,000 Euros (~$1,060), even in 16-inch format. For the supposedly affordable Lenovo LOQ 16 (1,500 Euros, ~$1,591), the manufacturer particularly saves in the equipment and materials compared to the more expensive Legion series. In addition, the LOQ is slightly heavier and more bulky. What remains is anything but a laptop full of difficult compromises. Instead, this is a more than solid gaming laptop that focusses on the 3D performance.Q is slightly heavier and more bulky."
