The Lenovo Legion Slim 5 offers a balance of affordability and decent performance, suitable for everyday use and some gaming. Being lighter and more affordable, it's ideal for students or casual users who prioritize portability and price over top-tier performance. In contrast, the Razer Blade 17, while more expensive, delivers high-end performance suited for intensive gaming, 3D modeling, or heavy multitasking. It boasts a larger, higher resolution screen, but this also means it's heavier, impacting its portability. If budget is a concern and you need a solid performer that can handle daily tasks with ease, go for the Lenovo. However, for the most demanding tasks and highest visual fidelity, the Razer is the appropriate choice despite its higher price and weight. Give Feedback

Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."

"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."
