Verdict
The decision to consider the HP OmniBook 3 depends pretty much on whether you see it as a pure office laptop or as a multimedia notebook.
This 17-inch laptop definitely has a right to exist in the first category in view of the moderate price, if you ignore the somewhat rickety input devices.
However, it is quite difficult recommend the OmniBook 3 as a multimedia notebook, as there are simply too many weaknesses and points of criticism overall, be it minor ones such as the limited upgrade options (RAM soldered, only one M.2 slot) or major ones such as the modest performance.
The AMD Ryzen 5 40 APU in particular, which we will examine in more detail later in the article, doesn't stand a chance against current processors. In combination with the rather poor SSD, the system often feels correspondingly slow.
This means that the name OmniBook 3 is not justified in our eyes, given the fact that even older games usually degenerate into jerky frames with the iGPU.
The fact that the rating is not even worse is partly due to the low consumption, which leads to more than solid runtimes despite the moderate battery capacity of 41 Wh.

The tested configuration and model number 17-dp0451ng with Windows 11 Home is available from various online stores such as Computeruniverse starting from €550.

For comparing the HP OmnBook 3 17's performance, we used the older Acer Aspire 3 A315 with the technically very similar Ryzen 5 7520U, and the current Lenovo models IdeaPad Slim 5 16 and IdeaPad 5 15 featuring the Ryzen AI 5 330 and Ryzen AI 5 430, respectively.
Additionally, the smaller brother OmniBook 5 16 with the Intel Core Ultra 7 255U is also in the tables.
Specifications
Chassis
The chassis cuts a good figure visually and impresses with its friendly, bright design reminiscent of metal, although the surfaces are only made of plastic.
Unfortunately, the stability leaves a lot to be desired in many places, and the lid can generally only be opened with two hands. The maximum opening angle is only around 130°.
That being said, the workmanship (read material transitions) leaves little to complain. With a weight of around 2 kg, the OmniBook 3 is not too heavy for a 17-inch laptop.
Equipment
HP gives the OmniBook 3 17 two USB-A 3.0 ports and two USB-C 3.1 Gen2 ports, the latter of which support Power Delivery and DisplayPort-out.
There are also an HDMI 2.1-out port and an audio socket. The manufacturer has however dispensed with RJ45 LAN and a card reader.
The Wi-Fi 6 module from MediaTek is a little slow by today's standards, and webcam images appear rather blurry and crumbly despite the Full HD resolution.
The internals can be accessed after removing five Phillips screws, though the bottom panel is quite tight due to various hooks.

Maintenance
Input devices
As mentioned at the beginning, the input devices are rather mediocre. The keyboard's lack of backlighting and unconventional layout take some getting used to.
Meanwhile, the touchpad could be more stable and sound less cheap when clicked.
Display
The 1,920 x 1,080 60 Hz display is surprisingly brighter than what the manufacturer's specifications suggest. Instead of 300 cd/m², we were able to measure an average of 374 cd/m², which is a useful value.
Thanks to the matte surface, there are also no annoying reflections. However, the image appears rather pale due to the poor 62% sRGB coverage and is not very color accurate in the delivery state.
Nevertheless, the OmniBook 3 17 has a reasonable contrast ratio of nearly 1,700:1. The viewing angles of the 16:9 screen are typical for an IPS model and the response times are somewhat below average.

Performance
16 GB of RAM and a 512 GB SSD are not a lot, but they are common in this price range. We'll get to the CPU and GPU performance in a moment.
It's a shame that the pre-installed Gaming Hub doesn't offer different operating modes to customize the system to your own needs and preferences.
Processor
The AMD Ryzen 5 40 may sound modern, but in the end it's just a Ryzen 5 7520U with an outdated Zen 2 architecture, as can be seen from the benchmarks.
The quad-core APU, which can handle a maximum of 8 threads, is no match for the current AMD offerings like the Ryzen 5 330 and Ryzen 5 430 (also 4C/8T), which are around 60% and 70% faster, respectively.
The same applies to the Core Ultra 7 255U, which can even be up to 90% faster.

System performance
It is, therefore, not surprising that the OmniBook 3 17 ends up at the bottom of our comparison charts in the system benchmarks. Even in everyday use when surfing the Internet etc., the computer sometimes seems sluggish in terms of response and loading times.

Storage performance
There is also room for improvement when it comes to the storage subsystem. The built-in M.2 drive from Western Digital is one of the slower SSDs, as can be seen very clearly in the table.
There were no speed drops in the disk loop test at least, which is often the case with faster models.

GPU performance
The Radeon 610M integrated in the Ryzen 5 40, only elicits a tired smile in 2026. While a Radeon 820M is almost 80 % faster in the 3DMarks, the Radeon 840M ends up with a plus of 170%.
An Intel Graphics 4-Core can even claim a lead of more than 200%.
