ASUS ROG Ally X vs Lenovo Legion Pro 5i 16 (2024)
The Verdict
These devices serve entirely different purposes and shouldn't be directly compared. The ASUS ROG Ally X is a 7-inch handheld gaming device weighing 678g with an AMD Ryzen Z1 Extreme and 24GB LPDDR5x RAM, designed for portable gaming with 3-10 hour battery life depending on game demands. The Lenovo Legion Pro 5i is a 16-inch desktop replacement laptop at 2.49kg featuring an Intel Core i9-14900HX with 32GB DDR5 RAM and a QHD+ 240Hz display, targeted at serious gaming and creative work. The Legion's superior specs (24-core processor, 2560x1600 resolution at 240Hz, dedicated graphics, 4x USB-A ports) make it far more powerful for demanding applications, but it sacrifices portability. The Ally X excels at what it's designed for: compact gaming anywhere with its 500-nit 120Hz display and solid 1TB storage. Battery life heavily favors neither in fair comparison terms. Choose based on your actual need: the Ally X for portable gaming on-the-go, or the Legion Pro 5i for stationary high-performance gaming and productivity. They're fundamentally different categories at vastly different price points ($799 vs $1599).
