The Dell Inspiron 15 3511 offers a lower midrange price point and is often significantly less expensive than the Lenovo Yoga Pro 9i, making it a more budget-friendly option. It has a larger storage capacity at 1024GB compared to the 512GB on the Lenovo, and double the RAM at 32GB, which is beneficial for multitasking. However, it has a less powerful processor and GPU, the Intel i5-1135G7 with Iris Xe graphics, which means it may not perform as well in more demanding tasks like gaming or engineering applications. The display is a standard 15.6-inch IPS panel with a resolution of 1920 x 1080, without touchscreen capabilities, and a lower refresh rate of 60Hz. It's also heavier and thicker, which affects its portability. On the other hand, the Lenovo Yoga Pro 9i, while pricier, comes with a more powerful Intel Core Ultra 7 155H processor and a dedicated Nvidia RTX 4050 GPU, which will provide better performance for gaming, 3D rendering, and machine learning tasks. Its 16-inch Mini LED display with a resolution of 3200 x 2000, touchscreen capabilities, and a higher refresh rate of 165Hz offers a superior visual experience, with better color accuracy and brightness, making it suitable for creative professionals. The Lenovo also features a more modern design with a 16:10 aspect ratio and better portability due to its thinner and lighter build. It includes a fingerprint reader for added security and has a longer battery life of 9 hours for typical usage. The keyboard quality is also rated as very good, and it has a better webcam and speakers. In summary, if you prioritize budget and need more storage and RAM for general use, the Dell Inspiron 15 3511 is a solid choice. However, if you're looking for a laptop with superior performance, a high-quality display, and better portability, and you're willing to pay a premium for these features, the Lenovo Yoga Pro 9i would be the better investment.

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."
