The Lenovo Slim Pro 9i is more expensive but offers better performance for intensive tasks like 3D rendering and machine learning due to its superior processor and dedicated graphics card. It has a higher-resolution display with better color accuracy, making it suitable for tasks where visual detail is important. On the other hand, the Lenovo ThinkBook 13s is lighter and more affordable, with sufficient capabilities for general use and basic engineering work. It has a longer battery life and a higher portability score, making it a better option if you prioritize mobility and value. Both devices support touch input and have backlit keyboards, but the ThinkBook 13s includes a Windows Pro operating system, which adds some business-related features. If you regularly perform demanding tasks and need a robust device, the Slim Pro 9i might be the better option; however, if you require a balance between cost, lighter travel, and battery efficiency for everyday tasks and less demanding engineering work, the ThinkBook 13s would be the wiser choice.

The Lenovo Slim Pro 9i has a better screen than the Lenovo ThinkBook 13s for general use, gaming and AI, engineering and design, software development, and content creation.
The Lenovo Slim Pro 9i excels in screen quality for general use and engineering due to its high resolution, bright display, and wide color coverage, offering vivid details and accurate colors. For general use and engineering tasks on the ThinkBook 13s, the good screen quality comes from its sufficient resolution and brightness, but it might lack the broader color spectrum of the Pro 9i. Both laptops fall short for gaming and 3D because they have lower refresh rates, which are less suitable for the fast-paced visuals those activities demand.

Matthew S. Smith | August 2023
"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."

"The best thing about the ThinkBook 13S is that it’s a good deal. Business buyers looking for ThinkPad-level performance and software without ThinkPad pricing will probably find the ThinkBook a solid option. While nothing about it is really spectacular, it’s certainly unusual to see the ThinkBook’s screen resolution at a sub-$1,000 price, and its performance will be more than adequate for most office tasks. The generous port selection, 16:10 aspect ratio, physical webcam shutter, and clear audio are certainly icing on the cake."
