For a balance of performance and portability with a focus on engineering tasks, the Lenovo Slim Pro 9i is a strong choice with its higher RAM, faster processor, and better GPU, ensuring smooth multitasking and demanding software handling. Its Mini LED display with a high resolution and color accuracy is excellent for detailed visual work, though it's slightly less portable due to its weight and size. On the other hand, the Lenovo Yoga Pro 9i offers a larger, high-resolution Mini LED touchscreen with superior color coverage, making it ideal for creative professionals who prioritize screen quality and versatility. It's also more portable with a longer battery life, but it compromises on RAM and processor speed, which might impact performance under heavy engineering workloads. Consider the Slim Pro 9i for its superior performance in intensive tasks and the Yoga Pro 9i for its outstanding screen and portability. Give Feedback

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."
