The Dell Alienware X17 R2 stands out for high-end gaming and demanding engineering tasks, but with a higher price and less portability. It offers superior performance for 3D rendering, machine learning, and overall gaming experiences with its premium hardware. If portability, higher screen resolution, and better value are priorities, the Lenovo IdeaPad Pro 5i may be a better choice. It provides good performance for general use and engineering, with a more attractive price and lighter form factor, making it easier to carry around. Consider your needs carefully: intense performance and gaming require the Dell, while the Lenovo balances cost and portability for everyday use and moderate demands. Give Feedback

The Dell Alienware X17 R2 is very good for gaming and AI, while the Lenovo IdeaPad Pro 5i is good.
The Dell Alienware X17 R2 is favored for intense gaming and 3D applications primarily because it features a high-end Nvidia RTX 3080 Ti GPU and an extremely high screen refresh rate of 480Hz, ideal for smooth, detailed visual performance. On the other hand, the Lenovo IdeaPad Pro 5i, although offering good performance for gaming with its Nvidia RTX 4050 GPU, has a lower screen refresh rate of 120Hz, which means it may not handle fast-paced games as smoothly as the Alienware.

The Dell Alienware X17 R2 has a better screen than the Lenovo IdeaPad Pro 5i for general use, gaming and AI, engineering and design, and content creation.
For general use, the Dell Alienware X17 R2 excels due to its high-resolution display and impressive brightness, offering clear and vibrant visuals, while the Lenovo IdeaPad Pro 5i also provides a high-quality display but may not be as bright. In the realm of engineering and design, the Alienware's coverage of color gamuts like DCI-P3 and Adobe RGB means accurate color representation crucial for precise work, whereas the IdeaPad Pro 5i offers good but not exceptional color accuracy. However, for gaming and 3D tasks, the Alienware's lower refresh rate could lead to less fluid visuals compared to laptops designed specifically for those purposes, even though it has a high resolution and good panel type, while the IdeaPad also lacks the high refresh rate that would benefit fast-paced gaming.

Allen Ngo | May 2022
"The Alienware x17 R2 recognizes targets a significantly higher TGP of 175 W for a roughly 30 percent performance boost over laptops running on the ~100 W GeForce RTX 3080 Ti like the Razer Blade 15 or Gigabyte Aero YE5. Similar results can be found through the CPU as well. This single aspect of the Alienware is perhaps the biggest differentiating factor between it and other ultrathin gaming laptops. Of course, the "performance at all cost" approach comes with drawbacks. Power consumption in particular is through the roof and battery life suffers because of it even when on the lowest performance settings."

"Lenovo’s IdeaPad Pro 5i represents an impressive opening salvo for Meteor Lake in the ultraportable space against familiar foes from AMD and Apple. Not only does the Core Ultra 5 125H processor provide good performance across the board, but battery life remains a strong point against the Acer Swift Edge 16 with its AMD Ryzen 7 7840U processor. It can’t quite match the endurance of the 15-inch MacBook Pro, but the gap is shrinking."
