The ASUS ROG Strix G15 Advantage Edition offers superior gaming and graphics performance due to its higher-end GPU and CPU, making it a better choice for intensive 3D tasks, machine learning, and gaming. However, it is heavier and bulkier, which affects its portability. On the other hand, the HP EliteBook 845 G9 is lighter and more portable with better battery life, making it a more suitable option for everyday use and business tasks. It has a business-grade build with a better webcam, a nicer screen ratio, and a higher resolution for productivity tasks. If gaming and graphics performance are not priorities, the HP EliteBook will be more convenient for regular use and travel. Both laptops are in a similar price range with the ASUS being more expensive, but with the extra cost, you get a machine more capable of handling demanding tasks. Give Feedback

Andrew E. Freedman | August 2022
"The Asus ROG Strix G15, as the first in a line of "AMD Advantage"-branded notebooks, is a statement that yes, you can get a premium AMD gaming notebook. Maybe you can't have it all, but you can get pretty close. The ROG Strix G15's combination of the AMD Ryzen 5900HX and Radeon RX 6800M, as well as other technologies that take advantage of them, make a potent, thin gaming machine. Powerful Dolby Atmos speakers and long battery life when you aren't gaming are nice bonuses."

"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."
