The HP workstation's display offers a very good contrast ratio of 3,054:1 and an equally very good black level of 0.13 cd/m². The color-space coverage of 98.5% (sRGB) and 63.7% (AdobeRGB) is very good as well.

The CalMAN analysis shows that the display isn't well calibrated out of the box. The Delta E 2000 deviation is 8.8, and colors show a greenish tint. After calibration, the maximum brightness falls by 40 cd/m², but the Delta E 2000 deviation drops to a very good value of 0.8, and colors are now displayed in a balanced way. The corresponding ICC file can be downloaded in the window located at the top, to the right of the display's brightness distribution graph.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
32 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 84 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.4 ms).
       Response Time 50% Grey to 80% Grey
56 ms ... rise ↗ and fall ↘ combined↗ 27.2 ms rise
↘ 28.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 91 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.6 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17788 (minimum: 5 - maximum: 3846000) Hz was measured.

The IPS panel of the ZBook Firefly 15 G8 is very viewing-angle stable. Content can be read from almost any angle without becoming distorted or showing incorrect colors.

Processor

The Intel Core i7-1165G7 used here is a quad-core processor from Intel's Tiger Lake generation. Its clock rates are between 2.8 and 4.7 GHz, and it can process up to eight tasks simultaneously. HP configures the i7-1165G7 with a PL1 of 25 watts and a PL2 of 51 watts. The 25-watt mark was also consistently reached during CPU-heavy tests.

Our benchmarks also show that depending on the discipline, the CPU performance of the ZBook Firefly 15 G8 is up to 25% higher than that of the ZBook Firefly 15 G7 predecessor. The HP workstation can also maintain its performance well under continuous load. Our Cinebench R15 long-term load curve only shows a slight drop of approximately 5%.

Our continuous load test with The Witcher 3 on the "Ultra" setting shows that the ZBook Firefly 15 G8 gradually loses performance in games. The cooling system can stop this trend after a while, but performance takes a sawtooth trajectory afterwards, which manifests itself in stagnant frame rates.

Emissions

Noise emissions

The fan of the Firefly 15 G8 is audible at up to 36.1 dB(A) under load, but it's not annoyingly loud. Furthermore, the resulting noise is uniform, and it blends well into the background noise. We didn't notice any coil whine or the like in our test device.

Temperature

Stress test
Stress test

According to our measurements, the surfaces of the ZBook Firefly G8 reach up to 47.2 °C (~117 °F) under load. The warmest spot is at the bottom on the center of the rear section, which means that the workstation can no longer be used without limitations on the lap, for example.

During our approximately one-hour stress test, the temperatures inside HP's workstation rose up to 85 °C (~185 °F). The clock rates also dropped to an average of 1.4 GHz, which is below the base clock speed. In addition, the CPU's power consumption of 12 watts only corresponded to the minimum TDP of the i7-1165G7. Since the system stabilized quite quickly after the test, and an amount of load such as in our stress test scenario shouldn't occur in everyday situations, users won't necessarily experience limitations due to excessively high temperatures.

Energy management - Long battery life

Energy consumption

With an average power consumption of 5.6 watts in idle usage and 64.4 watts under load, the HP ZBook Firefly 15 G8 is one of the most energy-efficient devices in our test field. Although the maximum consumption under load of 69 watts exceeds the 65-watt power adapter's capacity, this value is only reached for a short time, and it quickly settles between 49 and 60 watts.

Furthermore, the maximum values in the idle scenario are 6.5 watts without the keyboard backlight enabled, 7.7 watts when it's set to level 1, and 8.7 watts when it's set to level 2.

Battery life

The ZBook Firefly 15 G8 achieves a runtime of 10.5 hours in our real-world Wi-Fi test. This means that it can make good use of its 56 Wh battery, and it only has to admit defeat to competing devices with higher capacities. According to HP, fast charging is also supported with the included 65-watt power adapter, allowing 50% of the battery charge to be available again after half an hour.

In review: HP ZBook Firefly 15 G8. Test device provided by: HP Germany

With the upgrade to a Tiger Lake CPU and the new Nvidia Quadro T500, HP accomplishes one goal in particular, namely a significant increase in performance compared to the predecessor. The graphics unit represents the biggest leap. Although it still belongs to the entry-level segment, performance is practically doubled. Connectivity has also been upgraded, and Thunderbolt 4 is supported now.

The ZBook Firefly 15 G8 can almost double its graphics performance with the new Nvidia Quadro T500. However, the cooling system reaches its limits under maximum load.

HP leaves the design unchanged, which isn't a negative thing. However, the cooling system seems to slowly be reaching its limits, and there are also fluctuations in performance under prolonged load. This is not ideal for a mobile workstation, and this aspect should definitely be improved in the next model.

Price and availability

You can find the HP ZBook Firefly 15 G8 in the manufacturer's online store where you can customize it quite extensively. Prices will vary accordingly. For instance, the model with the same configuration as our test device currently costs around $2,600.
