The Lenovo Flex 5 16 is a more budget-friendly option and offers good performance for general use, with features like a touchscreen and decent battery life, making it suitable for everyday tasks and light to moderate multitasking. It's also relatively light and thus more portable. In contrast, the Razer Blade 17 is significantly pricier but provides high-end performance, particularly for tasks like 3D rendering, machine learning, and gaming, thanks to its more powerful processor and graphics card. However, it's heavier and has a shorter battery life, which could impact its portability. The Razer's superior screen resolution and refresh rate also make it better suited for graphic-intensive tasks and entertainment, but its higher specs mean it's less efficient in terms of battery consumption.

The Razer Blade 17 is very good for general use, while the Lenovo Flex 5 16 is good.
The Razer Blade 17 offers a more powerful CPU, greater memory, and superior screen quality, which elevates its capacity for handling a wide range of tasks more efficiently, while the Lenovo Flex 5 16's lower weight and longer battery life make it more suitable for users who prioritize portability and longer unplugged usage. However, the Razer Blade 17's higher screen resolution and quality as well as its extra storage and RAM capacity give it an edge in performance and multitasking, but these features come with a tradeoff in terms of reduced battery life and increased weight which may affect its convenience for on-the-go use.

The Razer Blade 17 has a better screen than the Lenovo Flex 5 16 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, both laptops offer sufficient resolution and brightness, with the Razer Blade likely having a slight edge in display sharpness and luminosity, enhancing the viewing experience for daily tasks. In engineering and design, the Razer's higher coverage of professional color gamuts ensures precise color representation crucial for detailed work. However, for gaming and 3D applications, the lower refresh rates on both models limit their ability to deliver the smooth visuals that these tasks typically require.

"The Lenovo IdeaPad Flex 5 is a solidly equipped, 2-in-1 in the lower price segment. Performance is definitely sufficient for everyday tasks and in tests the battery proved itself to be very economical. That aside, there is a lot of standard fare on show and a search for real highlights ends in vain. The low color coverage and reflective display can be avoided by going for an optional 2.5K display but this also presumably results in poorer battery life. The cooling uses only one fan and leads to a raised temperature on one side of the device under load. Additionally, there is very loud fan noise, also under load or when gaming. On top of that, we also occasionally noticed electronic noises."
"Our test configuration of the Blade 17 targets gamers and creative professionals. A Core i9-12900H processor, GeForce RTX 3080 Ti Laptop GPU (175 watts TGP after the BIOS update, 16 GB of VRAM), and 32 GB of working memory equip the laptop for video processing, rending, and 4k gaming at the highest level. In addition, a fast PCIe-4 SSD (1 TB) ensures short load and storage times. With the Blade 17 (Early 2022), Razer delivers a successful and powerful work device for creative professionals. But this also has its price."
