The Razer Blade 14 also boasts a higher resolution display and a more robust build, but it's more expensive and slightly less portable. The IdeaPad Slim 3, on the other hand, is budget-friendly, lighter, and has a decent battery life suited for everyday tasks. Give Feedback

The Razer Blade 14 has a better screen than the Lenovo IdeaPad Slim 3 for general use, gaming and AI, engineering and design, content creation, and software development.
The Lenovo IdeaPad Slim 3, with its fair screen attributes, is suitable for everyday tasks due to adequate resolution and brightness but lacks the wide color gamut needed for precise engineering and design work.

It's important to choose a laptop that aligns well with the primary activities it will be used for, balancing factors like color accuracy, brightness, and refresh rate against each other based on your specific needs.

Olivier Martin, Ryan Lim, and John Peroramas | May 2023
"The Lenovo IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."

Allen Ngo | May 2022
"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."
