HP ZBook Firefly 15 G8: Now with more performance but also with higher heat development

The ZBook Firefly 15 G7 already heated up considerably under load, but it could just about keep heat development under control. The follow-up model now shows a similar behavior.

As in the ZBook Firefly 14 G8, HP also uses a Tiger Lake CPU and Nvidia's Quadro T500 entry-level graphics unit for workstations in the Firefly 15 G8. This doubles graphics performance, and CPU performance is also up to 25% better with the Intel Core i7-1165G7 that we tested.

Like the ZBook Firefly 15 G7 predecessor model, the surfaces of the 8th generation also heat up noticeably. However, HP's workstation still remains usable with temperatures around 30 °C (~86 °F) on the palm rests. The bottom of the device heats up to 47 °C (~117 °F); therefore, you should avoid placing it on your lap without any protection.

While the CPU can also maintain its performance over a longer period in our Cinebench R15 endurance test, things look a bit different in the stress test. The CPU throttles its power consumption to 12 watts, the minimum rate for the i7-1165G7, under the extreme conditions of our continuous stress test. In contrast, a constant 25 watts was reached during the Cinebench R15 test.

This behavior shows that the cooling system of the HP ZBook Firefly 15 G8 is definitely capable of dissipating the generated heat. However, exceptional load scenarios can lead to performance throttling. Once you reduce the load again, the system stabilizes quickly, though.

HP has retained many characteristics of the predecessor model in the ZBook Firefly 15 G8, but it has also changed some aspects. We have documented the exact modifications in our review.

I carried out my first IT experiments with a 386-based system and a whole 4 MB RAM. This was followed by work on various PCs and laptops that I maintained and repaired for friends and acquaintances. After training to become a Telecommunications Systems Technician and gaining a few years of experience, I graduated with a Bachelor’s degree in Industrial Engineering. Currently, I pursue my fascination for IT, technology, and mobile devices by writing reviews and articles for Notebookcheck. I have also worked for Gamestar, Netzwelt, and Golem, among others.

I've been fascinated with technology ever since I got my very first Android smartphone, which was quite a while ago. The power packed into such a small footprint still amazes me. Learning to program made my understanding of technology deeper, and at the same time, it expanded my interest to the area of desktop computers and laptops. All this led me to enjoy reading and watching reviews of new devices, and that's how I stumbled upon Notebookcheck. I immediately found their reviews to be very comprehensive, and luckily, I've even had the chance of translating them since 2019. When it comes to the huge field of technology, I'm currently also interested in specializing in Java programming.
