If your priority is gaming or running graphics-intensive tasks such as 3D rendering and machine learning, the Razer Blade 17 is the better choice due to its more powerful graphics card. However, the Lenovo Slim Pro 9i is lighter and offers a higher portability factor, making it more suitable for travel or daily commuting. The trade-off between these laptops is between performance and portability. Additionally, the Lenovo has a touchscreen, while the Razer does not, but the Razer offers a larger screen which could be more appealing for entertainment and professional work that benefits from a larger display. Generally, the Lenovo Slim Pro 9i might be more cost-effective, while the Razer Blade 17 while more expensive, provides superior performance for demanding applications. Give Feedback

The Lenovo Slim Pro 9i is well-suited for engineering and design due to its high-resolution Mini LED touchscreen and a dedicated Nvidia RTX 4050 GPU, which is complemented by a powerful Intel i7 CPU and ample RAM for multitasking.

"The Lenovo Slim Pro 9i is an impressive laptop with a brilliant Mini-LED display, a powerful 100-watt version of Nvidia RTX 4050 graphics, and excellent connectivity. Having run the Cinebench benchmark again, we were impressed with the CPU performance. That makes the Slim Pro 9i is an easy recommendation, especially for those who care about GPU and CPU performance. It’s also a fantastic choice if you frequently view HDR movies and games on your laptop."

"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."
