For better performance in 3D rendering, machine learning, or gaming, the ASUS ROG Flow X16 is superior thanks to its more powerful GPU and CPU. However, it is heavier and has a shorter battery life, making it less ideal for travel. The HP EliteBook 845 G9 trades some performance for significantly longer battery life and greater portability due to its lighter weight, and it excels in build and webcam quality. The ASUS has a higher quality display with a higher resolution, refresh rate, and color coverage, beneficial for creative professionals, while the HP has a pro operating system, which can be better for business use.

The ASUS ROG Flow X16 has a better screen than the HP EliteBook 845 G9 for general use, gaming and AI, engineering and design, and content creation.
The ASUS ROG Flow X16 has a high-resolution display with vibrant colors and brightness, making it ideal for everyday tasks and detailed engineering work due to its broad color coverage. However, its refresh rate is lower, which is less optimal for fast-paced gaming and 3D rendering that benefit from smoother motion. In contrast, while the HP EliteBook 845 G9 also provides clear and accurate colors for both general and professional design use, it shares a similar shortfall in refresh rate, not suiting it to gaming or 3D applications where rapid visual updates are key.

Although they have very similar scores, PerfectRec considers ASUS ROG Flow X16 to be very good for general use, while the HP EliteBook 845 G9 is good.
The ASUS ROG Flow X16 is well-suited for general use owing to its high-performance CPU and gaming-capable GPU, making it versatile for both common tasks and graphically intensive applications, though its larger screen and higher battery capacity can compromise its portability. The HP EliteBook 845 G9, while more portable given its smaller screen and lighter weight, focuses on efficiency with a lower-tier CPU and integrated graphics, and offers a decent screen and battery life for everyday tasks without the gaming or high-end graphics capabilities.

How the ASUS ROG Flow X16 and the HP EliteBook 845 G9 compare to other laptops
"Above all else, the Asus ROG Flow X16 is one thing - versatile! It is a thin, mobile work device, it's a 2-in-1, tablet, a powerful workstation and even a gaming PC. But something even more surprising: It does all of these things really well without making any big blunders. It's anything but a lazy compromise. Because, despite its compact dimensions and 2-in-1 functionality, the hardware isn't throttled and boasts, at least in turbo mode, above-average performance."
"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."
