The Dell Inspiron 14 7435 and Lenovo Flex 5 14 are both suitable for general use and light engineering work, with similar RAM, storage, and processors. The Dell tends to be less expensive and offers more USB-C ports and a slightly larger battery, but the Lenovo Flex boasts longer battery life and a brighter screen. Both have a 14-inch touchscreen display, are similar in size and weight, offer backlit keyboards, and lack dedicated graphics for intensive gaming. The choice between them hinges on whether longer battery life and screen brightness (Lenovo) or lower cost and additional connectivity (Dell) are more important for your needs. Give Feedback

The Lenovo Flex 5 14 has a better screen than the Dell Inpsiron 14 7435 for general use, and engineering and design.
If you're mainly browsing the web, working with documents, or streaming video, both the Dell Inspiron and the Lenovo Flex have decent screens with resolution and brightness levels that are adequate for these tasks. For engineering and design work, where accurate colors are crucial, both models offer only satisfactory performance as they lack a wide color gamut, making them less ideal for professional color work. However, for gaming and 3D applications that demand smooth motion, neither laptop is suitable due to their lower refresh rates, meaning you'll experience less fluid visuals compared to laptops designed with gaming in mind.

The Dell Inpsiron 14 7435 and Lenovo Flex 5 14 are both only fair for gaming and AI.
The Dell Inspiron 14 7435 and Lenovo Flex 5 14 are considered fair for gaming and 3D as both laptops have GPUs that are integral for such tasks, but they offer modest performance compared to more gaming-focused GPUs, and both have a standard screen refresh rate of 60Hz which isn't as fluid as higher rates desired for gaming. Additionally, they share comparable CPUs and screen quality, important for smooth gameplay and clear visuals, but the CPUs are not the top-tier available and the screen quality, while adequate, may not meet the standards of more expensive gaming laptops.

How the Dell Inpsiron 14 7435 and the Lenovo Flex 5 14 compare to other laptops
"We see no shame in an economy laptop missing the four-star mark. Frankly, we considered giving the Inspiron 14 2-in-1 three-and-a-half stars for its low price, competitive performance, and long battery life. Unfortunately, working with a screen that can't deliver at least 300 nits of brightness is simply no fun to the point of detrimental. Still, if you're looking for a convertible laptop on a tight budget, it's worth keeping an eye on Dell's sales and discounts. That Lavender Blue model is fairly tempting."
"The highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
