For a balance of performance and portability with a focus on gaming and creative tasks, the Dell Alienware m15 R7 is a strong contender, offering a high-refresh-rate display and powerful graphics with the Nvidia RTX 3070 Ti, suitable for intensive gaming and engineering work. However, it's heavier and has a shorter battery life compared to the Lenovo Yoga Pro 9i. The Yoga Pro 9i, on the other hand, is a versatile choice with a touchscreen and superior color accuracy, making it excellent for general use and professional work that requires color precision. It's also more portable, lighter, and has a longer battery life, but its gaming and engineering performance is less robust due to the less powerful Nvidia RTX 4050. Consider the Alienware for performance-intensive tasks and gaming, and the Yoga Pro 9i for general use and portability with a superior display for color-critical work. Give Feedback

Tom's Hardware
Brandon Hill | October 2022
"The Alienware M15 offers solid gaming and leading endurance. It makes the most of its CPU and GPU while delivering stellar battery life for a gaming laptop. Opening the lid presents a full-size keyboard with honeycomb cutouts above it on the deck. An oblong RBG lightning element surrounds the entire rear panel and can be color-synced with the other lights on the laptop. There’s not a lot to dislike about the M15 Its productivity performance lagged in some areas, particularly in the storage benchmark, and it’s a bit heavy. Alienware has a clear winner here with the M15 based on its strong overall performance and endurance."
