The Acer Aspire 3 14 is a budget-friendly laptop that offers good general performance for everyday tasks with moderate battery life and portability. It is not designed for intensive gaming or heavy engineering tasks due to its modest processor and graphics card. In contrast, the Dell Alienware m15 R7 is more expensive but is built for high performance with a powerful processor and graphics card suitable for intensive 3D rendering, machine learning, and gaming. It is heavier and less portable, but the higher resolution display and more substantial build quality could make it a better choice for demanding applications. 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."
