The Dell Alienware m15 R7 is a premium option with more powerful components providing better performance for intensive gaming, 3D rendering, machine learning, and engineering tasks. It has a larger battery, but it's also heavier and less portable than the Gigabyte G5, which may matter if you travel a lot. The G5 offers a lower price and could suffice for general use and moderate gaming, but it does not match the Alienware's performance for demanding applications. Both have high refresh rate displays, but the Alienware has a higher resolution screen, contributing to a better visual experience at the cost of battery life. 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."

"The Gigabyte G5 KE is a midrange gaming laptop that checks most boxes. Gigabyte makes good use of the Core i5-12500H and RTX 3060 Laptop GPU combo, and we find no untoward issues with overall performance. The dual-fan quad-heatpipe cooling arrangement does well to ensure that the underlying hardware doesn't throttle under load. That being said, the display is below par when compared to 2023 standards, especially when competing devices."
