The Lenovo Legion Slim 7 offers a good balance between performance and portability, making it a viable choice for both work and play, especially if you are looking for a lighter and thinner option that is less expensive. On the other hand, the Razer Blade 17 has more powerful internals, which translates to superior performance for 3D rendering, machine learning, and intensive gaming, but it comes at a higher cost and with more weight, potentially impacting its portability. Consider what you value most: if it's portability and price, go with the Lenovo; for top performance in demanding tasks despite a higher price and less mobility, choose the Razer. Give Feedback

Benjamin Herzig | November 2022
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."

"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."
