Based on your needs, consider the Dell Alienware m15 R7 if top-tier gaming performance, a higher resolution display, and premium graphics capabilities are paramount, albeit with a higher price tag and heftier build, making it less portable. On the other hand, the HP EliteBook 845 G9 is typically much less expensive and more suitable for general use and business applications, due to its midrange price, moderate weight, and more conservative design. It also offers a longer battery life for on-the-go productivity but with less graphical power, which might not be suitable for intensive 3D tasks or gaming. 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 high-end version of the HP EliteBook 845 G9 with a Ryzen 9 PRO 6950HS, 32GB of RAM and a 1 TB SSD packs a lot of power, but is still quiet and cool enough to operate in noise-sensitive environments. Quiet, cool and drawing on a massive 40 watts from the APU at the same time, however, is not possible. The 14-incher only has a single-fan solution and it only just manages to keep an near unthrottled Ryzen 9 in check."
