If you need a laptop with higher storage, more RAM, and a higher resolution touchscreen for tasks like photo/video editing or multitasking, the ASUS ZenBook Pro Duo 15 is a strong option, but it's heavier and offers less battery life compared to some competitors. On the other hand, if you prefer a more gaming-focused laptop that still offers good performance for general use and engineering tasks, the Dell Alienware m15 R7 could be a better fit, with its high refresh rate display and RGB keyboard, yet less storage and RAM than the ASUS. Keep in mind, both have powerful GPUs for demanding tasks, but the ASUS nudges ahead in creative tasks with its dual-display feature. Give Feedback

Jared Newman | August 2021
"Benchmarks aside, the Asus ZenBook Pro Duo is hard to compare with other PCs. Its closest competition may be a multi-monitor desktop, or a laptop with an attached travel monitor. The Pro Duo is more portable and versatile than either of those options, especially with the software tools Asus has thrown on top. For a certain niche of artists, media creators, and gamers, all that might add up to something special, even if it’s unattainable for the rest of us."

"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."
