When choosing between the Lenovo Slim Pro 9i and the ThinkPad T14, consider that the Slim Pro 9i typically offers a sleeker design and potentially better display quality, which is suitable for media consumption and general use, while the ThinkPad T14 is designed with durability and business use in mind, often with more ports and a more rugged build. The Slim Pro 9i may have a higher cost, but it could also provide a more premium experience for everyday tasks and entertainment. Conversely, if you prioritize longevity, a keyboard designed for heavy typing, and enterprise features over a thin and light form factor, then the ThinkPad T14 may be the better investment despite the tradeoff in portability and possibly display and audio quality.

The Lenovo Slim Pro 9i has a better screen than the Lenovo ThinkPad T14 for general use, gaming and AI, engineering and design, and content creation.

However, its lower refresh rate makes it less optimal for the smooth visuals required in gaming and 3D modeling. Conversely, the ThinkPad T14 offers a balanced solution with good quality visuals for everyday and engineering tasks, but like the Slim Pro 9i, its refresh rate isn't suited for the high-paced fluidity needed in gaming and 3D applications.

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."

"We like a lot about this laptop. It has many ports, with the inclusion of RJ45-Ethernet as a defining feature. WWAN is upgradable for maximum flexibility and the ThinkPad has many security functions. Working with the ThinkPad input devices is a lot of fun, and Lenovo puts in a serviceable Low Power panel. The AMD Ryzen 7 Pro 7840U delivers a great performance and does not drain the battery fast. Fan noise and temperatures are nothing special, but also far away from bad. With the user replaceable keyboard, the ThinkPad T14 Gen 4 has a special feature rarely present on most modern laptops."
