The Jumper 14" Laptop is often less expensive than the Lenovo Flex 5 and it's lightweight, making it more portable, but it has lower performance due to its Intel Celeron processor compared to the Lenovo's AMD Ryzen 7, which is far better for demanding tasks and multitasking. The Lenovo also has a higher resolution display, more RAM, and more storage. Battery life is superior on the Lenovo, and it doubles as a 2-in-1 convertible, so you can use it as a tablet, which the Jumper can't do. If you need power and versatility and can afford it, go for the Lenovo Flex 5. If budget and portability are your primary concerns, consider the Jumper. Give Feedback

The Lenovo Flex 5 14 is only fair for gaming and AI, while the Jumper 14" Laptop is poor.
The Jumper 14" Laptop's gaming and 3D performance is poor due to its weaker Intel UHD Graphics 600 and less capable Celeron J4105 processor compared to the Lenovo Flex 5 14, which has a fair performance owing to its more powerful integrated AMD Ryzen 7 7730U Vega 8 graphics and robust Ryzen processor. Both laptops have the same refresh rates, but the Flex 5's superior screen quality, including resolution and brightness, contributes to a better gaming and 3D experience.

The Lenovo Flex 5 14 has a better screen than the Jumper 14" Laptop for general use, engineering and design, content creation, and software development.
For general use, both the Jumper and Lenovo Flex 5 laptops offer satisfactory screen quality due to their decent resolution and brightness, making them suitable for typical activities like browsing and watching videos. In engineering and design, their screens fall short in displaying the wide range of colors professionals require, as they do not fully cover professional color gamuts like DCI-P3 and Adobe RGB. When it comes to 3D and gaming, their screens are less ideal because of lower refresh rates, which can lead to less fluid visuals during fast-paced scenes or interactive 3D rendering.

"For the vast majority of people looking for a beautiful, affordable, and portable laptop, the Jumper EZbook S5 is a perfect choice. It’s surprisingly capable of things like web browsing, Office, webmail, and beyond. The experience offers a few compromises when it comes to more intensive tasks, but for college students looking to save money, or someone looking to buy their kid a basic daily-use laptop, this is truly one great option."
"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."
