The ASUS ROG Flow Z13 is better for gaming and other graphics-intensive tasks due to its more powerful processor and graphics card, but it has a shorter battery life and is slightly heavier, making it less portable. The HP EliteBook 845 G9 offers better battery life and portability, plus it comes with Windows 11 Pro instead of Home. It is less expensive and has a business-oriented design, but it is not as well-suited for heavy 3D rendering or gaming due to its less powerful AMD graphics. Both laptops have 16GB of RAM and high-quality IPS displays, but the ROG's screen is better suited for fast motion and has higher color accuracy. Give Feedback

How the ASUS ROG Flow Z13 and the HP EliteBook 845 G9 compare to other laptops
"The Asus ROG Flow Z13 is a gaming tablet with powerful Alder Lake i9 CPU. The ROG Flow Z13 impresses with its good cooling. After our review, the impression is predominantly positive. Besides a very fast Alder Lake CPU and stable gaming performance, especially the cooling system is surprisingly effective and quiet. You can use the integrated speakers without any issues while gaming. The 1200p display in the 16:10 format also impresses with good color reproduction and high brightness. Since the battery runtimes aren't particularly long as it is, we wouldn't recommend the optional 4K panel."
"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."
