HP ZBook Power 15 G9 laptop review - Mobile workstation with a matte 4K display
HP offers various mobile workstation model series, starting with the thin ZBook Firefly entry-level devices, followed by the ZBook Studio, the ZBook Fury high-end models, and the ZBook Power, which is supposed to represent a good combination of price and performance. While the case is not particularly slim, this also brings with it a sufficient number of ports. We test the ZBook Power 15 G9 6B8C4EA version for around 2,800 Euros (~$2981), which is very well equipped with a Core i7-12700H, the RTX A2000, 32 GB of RAM, a 1-TB SSD, and a matte 4K display. Compared to the ZBook Power 15 G8 predecessor (here in our test), there are no changes in the case and input devices, so we will keep those sections short here, focusing instead on the performance sections.

Case and Equipment
The aluminum case remains unchanged from the previous G8 model. While the quality is good overall, the stability doesn't quite reach that of the more expensive workstation models such as the ZBook Studio or ZBook Fury. In addition, the display wobbles slightly after changing the opening angle. Visually, the ZBook Power 15 G9 looks modest and unremarkable with its darker gray color. The bottom of the case is only screwed in and can be removed easily. Besides the working memory, you can also access the two M.2 SSD slots, but the WLAN module is soldered in.
In terms of the connection equipment, there continues to be a number of USB-A ports as well as USB-C with Thunderbolt 4, Ethernet, and an HDMI port. However, it lacks a card reader. The WLAN module was upgraded, and the AX211 card from Intel now also supports the Wi-Fi 6E standard. We are able to connect to the 6-GHz network from our Asus reference router without any problems. The transfer rates we measure are very high and also stabile. An LTE/5G module is not available for the ZBook Power.
As the webcam, there continues to be a 720p sensor including an IR camera for face recognition. The webcam does its job, but the image quality is not very good even in good light conditions.

Input Devices - ZBook Power with a good keyboard
Compared to the ZBook Power 15 G8, there are also no changes in the input devices. The keyboard with background illumination offers a very good typing experience, and there is a dedicated number block on the right side. In terms of the layout, you have to get used to the slightly smaller arrow keys and the Power button in the top key row. The fingerprint scanner is placed on the right, below the keyboard. In our test, the ClickPad works reliably, but the clicking sound is a bit loud.
Display - 4K IPS with 100% sRGB coverage
We already tested the regular Full HD panel with the predecessor, and our current test configuration of the ZBook Power G9 is equipped with the optional low power 4K IPS display. As in the predecessor, this still has the 16:9 format (3,840 x 2,160 pixels). Subjectively, the LG-Philips panel produces a good image quality, but bright contents appear slightly grainy on the matte display surface. In addition, the response times are not particularly fast, and we also see some clear ghosting effects in practice, for example in the mouse pointer.
HP advertises a brightness of 400 cd/m², and our test unit also achieves this in the top range. At the same time, the black value is very low at 0.15, leading to a very good contrast ratio of more than 2,500:1. At full brightness and with a dark background, there are some noticeable light halos. PWM is not used.

* ... smaller is better
We measure the panel with the professional CalMAN software. There is a clearly visible red tint in the state of delivery, and the color temperature is also too warm. This is unfortunate, since we are able to significantly improve the display with our own calibration (color profile available for free download from the link above), which leads to excellent results particularly in the grayscale and completely gets rid of the color tint. The color deviations compared to the reference sRGB color space (which is covered fully) are also slightly lower, leaving only 100% blue as an outlier. However, the calibrated panel is still suitable for image processing.

Outdoors, the display benefits from the matte surface, and as long as you avoid direct reflections of light sources, you can still easily recognize the display contents even on bright days. The viewing angle stability of the IPS panel is very good.
Performance - ZBook with Intel Alder Lake
Test Conditions
HP doesn't offer any additional power configuration options. During the test, we are able to observe some strongly varying performance values. While the situation is improved slightly with some BIOS updates, it still isn't completely stable. With 105/75 watts, the TDP values are basically configured high, but the processor is only able to use up to 90 watts at most for one second once a while, before it quickly levels out at around 55 watts. At times, the processor even starts out with this value (with previous BIOS versions, it was even less than 40 watts).
Processor
The Core i7-12700H comes from Intel's current Alder Lake generation, combining 6 fast Performance cores with 8 Efficiency cores. The single-core performance is very good and about 15-20% faster than that of the predecessor with the Core i7-11800H. However, in the multicore benchmarks the performance is slightly disappointing considering the large case, with a lot of potential remaining unused. For example, the ZBook Studio 16 G9 with the same processor is about 20% faster in the multicore tests. We also try to raise the TDP values manually, but the cooling is unable to handle more than 60-65 watts, since the CPU temperatures will then increase to more than 95 °C (203 °F).
In battery operation, the power consumption of the CPU is limited to 30 watts. This has no influence on the single-core performance, but results in a performance deficit of around 30% in the multicore tests (9,926 points CB R23 Multi). You can find additional CPU benchmarks in our technical section.

Storage Solution
The ZBook Power 15 G9 offers two fast PCIe 4.0 slots for M.2 SSDs. Our test unit uses a large, 1-TB PM9A1 from Samsung (OEM version of the 980 Pro). After turning it on for the first time, 890 GB of this are available to the user. The transfer rates of the SSD are excellent, and the performance also remains almost completely stable even after longer load. You can find additional SSD benchmarks here.

Graphics Card
The Nvidia RTX A2000 is the fastest GPU that HP offers for the ZBook Power 15 G9. This is the updated version with 8 GB of GDDR6-VRAM. However, the GPU is only allowed to consume a maximum of 45 watts (including 5 watts Dynamic Boost), which makes it one of the slowest versions. In our benchmarks, the GPU therefore also drops below the average of the results that we measured for the RTX A2000 so far. The gaming performance is comparable to that of the GeForce RTX 3050 Ti consumer GPU, but thanks to the certified drivers, the performance in professional applications can also turn out significantly better.
Under constant load, the GPU performance remains completely stabile. As already in the processor, the power consumption of the graphics card in battery operation is also limited to 30 watts, leading to a performance reduction of almost 25% (3,589 points Time Spy Graphics). You can find additional GPU benchmarks here.

Emissions and Power Management
Noise Level
Usually, the two fans of the ZBook Power 15 G9 often remain deactivated during simple tasks. Only when you put the processor or dedicated graphics card under load do the fans turn on quickly, usually producing a noise level between 42 and 45 dB(A), with the speed of the fans not always remaining stabile but fluctuating sometimes. During the stress test with maximum load for the two components, we measure a maximum of 47.9 dB(A). With this, the current G9 generation remains slightly quieter than the predecessor. There are no other electronic noises.

Temperatures
The surface temperatures of the mobile workstation usually remain very low in everyday operation, giving no reason for concern at all, even under load. At 48 °C (118 °F), the only hotspot is at the bottom in the central area toward the back, but due to its position, you can still place the device on your lap. However, the top of the base unit, including the keyboard, remains significantly cooler at a maximum of 40 °C (104°F).
During the stress test, the processor levels out at 35-39 watts after a brief peak of 90 watts, while the graphics card remains stable at 40 watts. After the stress test, the performance is not reduced. In battery operation, the values drop slightly, with the CPU still being allowed to consume 25 watts and the GPU, 30 watts under combined load.
(±) The maximum temperature on the upper side is 40.3 °C / 105 F, compared to the average of 38.2 °C / 101 F, ranging from 22.2 to 69.8 °C for the class Workstation.
(-) The bottom heats up to a maximum of 48.3 °C / 119 F, compared to the average of 41.2 °C / 106 F
(+) In idle usage, the average temperature for the upper side is 23.1 °C / 74 F, compared to the device average of 32 °C / 90 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 33.5 °C / 92 F, compared to the device average of 32 °C / 90 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 28.6 °C / 83.5 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.8 °C / 82 F (-0.8 °C / -1.5 F).

Speakers
The two stereo speakers represent one of the weaknesses of the mobile workstation, since their sound is very thin and hardly convincing. While they do their job during video conferences or voice calls, we would definitely recommend using headphones or external speakers for the reproduction of music or movies.

Power Consumption
Despite the 4K display, the ZBook Power 15 G9 is a very efficient device with a maximum of 8.5 watts during idle operation. Under load, you can expect about 85-100 watts, and after a short consumption peak of 139 watts, it also levels out in that range after several minutes during the stress test. The included 150-watt power supply is therefore completely sufficient.

Battery Life
The large 83-Wh battery remains unchanged, allowing for a good battery life, even if the predecessor with a Full HD panel still lasted longer. Considering the 4K panel, with around 10 hours in our WLAN test at 150 cd/m² (corresponding to 65% of the maximum brightness in our test unit) and still 9 hours at maximum brightness, the results are very good. The low-power display becomes definitely noticeable here.
I takes about 2.5 hours to completely recharge the device when it is turned on, with 50% of that already being available after 34 minutes, and 80% after 70 minutes.
Pros
Cons
Verdict - The HP ZBook Power 15 G9 would benefit from more powerful cooling
The ZBook Power 15 G9 is an entry-level workstation, targeting users who need a reliable performance and professional graphics cards. Aside from the processor, our test configuration already corresponds to the maximum configuration with the 4K display, the Nvidia RTX A2000, and abundant storage, which of course also drives up the price. Like its predecessor, the ZBook Power G9 also offers a solid performance in many areas. But particularly in the CPU performance, the results again are not always constant. The situation has slightly stabilized with some BIOS updates, but the workstation is still unable to make full use of the real potential of the Core i7-12700H.
Particularly in terms of the performance development, the ZBook Power 15 G9 is unable to reach top values, but thanks to some BIOS updates, the CPU performance has stabilized to a large extent. After a calibration, the low power 4K display offers a good image quality and allows for a long battery life.
However, to be fair we also have to mention that the entry-level workstations from the competitors, such as the Lenovo ThinkPad P15v or Dell Precision 5560 don't deliver much more performance either, with the three models performing at eye level overall. The 4K panel is basically a very good choice, since it runs very efficiently without driving up the power consumption, but you should calibrate it if possible.
Price and Availability
The ZBook Power 15 G9 is currently available directly from HP starting from about $1455, and some configurations are also available from Amazon, for example.
