HP ZBook Firefly 15 G8 2C9R7EA

The hardware configuration of the ZBook Firefly 15 G8 that we have before us already achieved a good result in our review of the HP ZBook Firefly 14 G8. However, we'll compare the performance provided by this combination of the Intel Core i7-1165G7, the Nvidia Quadro T500, 16 GB of RAM, and a 1 TB SSD with the predecessor model, the ZBook Firefly 15 G7.

Since the looks and basic connectivity haven't changed much, we will also refer to the review of the Firefly 15 G7 in some places. In addition, we have the competing devices listed below, to which further laptops from our database can be added under each section.

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 0.8 (minimum) to 240 (maximum) ms. » 81 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24 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 0.8 (minimum) to 636 (maximum) ms. » 90 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.1 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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 14825 (minimum: 5 - maximum: 2500000) 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.

Graphics card

The ZBook Firefly 15 G8 is equipped with an Nvidia Quadro T500. This entry-level graphics card for workstations is based on the GeForce MX450, but it offers slightly higher clock rates. The variant with 4 GB of video memory is installed here; HP doesn't offer the 2 GB version.

In the 3DMark benchmarks, the ZBook Firefly 15 G8 can almost double its performance compared to the Nvidia Quadro P520 in the ZBook Firefly 15 G7. The performance that can be expected from other graphics cards in comparison can be found in our GPU Benchmarks article.

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.

(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 29.9 °C / 85.8 F and are therefore cool to the touch.
(-) The average temperature of the palmrest area of similar devices was 27.8 °C / 82 F (-2.1 °C / -3.8 F).

Speakers

The speakers of the ZBook Firefly 15 G8 offer medium volume and a fairly broad sound spectrum. This makes them suitable for occasional media playback in quiet environments, but external speakers or headphones are still recommended in the long run.

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.
