If you prioritize higher performance for tasks like gaming or 3D rendering, the Razer Blade 14 with its powerful processor and graphics card is a strong choice, though it comes at a higher price. It also boasts superior color accuracy and higher refresh rates making it better for tasks requiring precision in visuals and for smooth gameplay. On the other hand, the Lenovo Flex 5 is more budget-friendly and offers a touchscreen with a versatile 2-in-1 design, longer battery life, and lighter weight for easier portability. However, its graphical performance and processing power are less than the Razer Blade, making it suitable for general use and less demanding engineering tasks. Give Feedback

The Razer Blade 14 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 the Lenovo Flex 5 16 and the Razer Blade 14 boast displays with clear resolutions and brightness levels that make everyday tasks pleasant, though the Razer takes the edge with a sharper and potentially brighter display. In engineering and design, color accuracy is key, and both laptops offer screens with a range of colors, but the Razer Blade might provide richer colors essential for precise design work. However, neither laptop is ideal for gaming or 3D due to lower refresh rates, which means they won't be as smooth in displaying fast-paced actions or rendering 3D animations compared to laptops with higher refresh rates.

How the Lenovo Flex 5 16 and the Razer Blade 14 (2023) compare to other laptops
"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."
"After making a huge splash with the original 2021 model, it's expected that the 2022 refresh would be more of a minor update to an already impressive machine. It adds a higher resolution webcam (720p to 1080p), faster CPU (Ryzen 9 5900HX to Ryzen 9 6900HX), faster GPU (RTX 3070/3080 to 3070/3080 Ti), faster RAM (DDR4-3200 to DDR5-4800), faster M.2 SSD support (PCIe3 x4 to PCIe4 x4), newer WLAN module (Killer AX1690i to Qualcomm WCN685x), and a MUX switch for the new integrated Radeon 680M GPU. It's indubitably an upgrade especially in terms of single-thread processor performance."
