Review: HP’s ZBook 15 and 17 G6 are impressive professional workstations
Source: Windows Central
HP’s lineup of powerhouse laptops has now entered its sixth generation with the ZBook 15 G6 and ZBook 17 G6. There are a number of improvements to what HP calls the world’s best-selling mobile workstation, but the fact that these deliver above-average performance for specialized work has not changed. They’re rather large, heavy, and expensive, but the features offered are worth the tradeoff for those that need them. Let’s take a look at the ZBook 15 and ZBook 17 to see what they’re all about in this dual review.

The more expensive 17-inch model I’m reviewing is equipped with the same Intel Xeon CPU, 64GB of RAM split up over four 16GB sticks, a 1TB PCIe NVMe SSD, 4K DreamColor display, and NVIDIA Quadro RTX 5000 GPU. Altogether it costs about $10,393 before discounts, which bring the price down to about $6,444. It’s clear just from the price these are not laptops for the average user. They’re built for engineers, architects, editors, developers, and designers who don’t want to sacrifice desktop performance when going mobile.
Here’s a breakdown of the hardware in each of our review models. As you can see, there are a lot of similarities once you get past the physical size.

Design and features
Looking back at the G5 models, not a lot has changed physically for the G6 update. Dimensions are about the same for the aluminum chassis, you still get a ton of ports, and the keyboard and touchpad are laid out the same. HP has, however, upped the number of MIL-STD 810G durability tests from 14 to 21. The laptops are going to theoretically better withstand drops and solar radiation (like if you leave your laptop in your car on a hot day). Holding these devices, it’s hard to imagine them taking significant damage. As an added bonus, the chassis doesn’t pick up nearly as many fingerprints as a ThinkPad.
Connectivity is ample in both laptops, but the ZBook 17 brings a few extra options. On top of the ZBook 15’s two Thunderbolt 3, HDMI 2.0, three USB-A 3.0, Ethernet, 3.5mm audio, SD card reader, and optional Smart Card reader, the ZBook 17 brings an optical drive and Mini DisplayPort 1.4. You can connect something like HP’s Thunderbolt Dock G2 to either laptop for extra ports. Everything is well positioned for the most part; I just wish the ZBook 17 had USB-A on the right side to handle any external mice. My hand hit the release on the optical drive a few times while carrying the laptop around, but it’s something that can be avoided once you know where it’s located.
Keyboard, cameras, and audio
Source: Windows Central
The sizable Precision touchpad is bordered by two sets of physical buttons, one for the touchpad itself and one for the nub pointer that’s located between G, H, and B keyboard keys. The touchpad doesn’t actually click down so it’s either a tap or a physical button.
Audio from the ZBook is loud and clear. These are not your average Ultrabook speakers.
The ZBooks still have dual microphones to better pick up your voice while conferencing, and a third world-facing mic with noise cancellation is intended to cut out chatter from the surrounding world. HP also included dedicated collaboration keys on the keyboard so you can quickly pick up, mute, and adjust call volume when talking with colleagues.
Speakers got a workover for the G6 ZBooks, and the result is impressive. They’re located on both laptops above the keyboard for top-firing orientation that’s not muffled. A discrete amp chip on the speakers helps audio get overly loud, up to about 74dB, and there’s no noticeable distortion at high levels. These are not your average Ultrabook speakers.
Rounding out some of the professional features is optional LTE connectivity. Neither review model includes the necessary network card, but there is a clear space for it inside. If you need to stay connected at all times, even outside of Wi-Fi zones, it’ll be well worth the extra bit of money. These laptops are also compatible with Wi-Fi 6 for extremely fast wireless speeds.
Display

HP’s DreamColor 4K screens are a step above other professional displays I’ve tested.
Picture from both is incredible thanks to a billion colors and perfect contrast. The 15-inch model hits about 600 nits brightness while the 17-inch model tops out at about 400 nits. In either case, screens were bright enough to be seen clearly in a well-lit room. Adaptive brightness handles most adjustments accurately for a better user experience. Thanks to DreamColor Assistant software there are a number of color presets to choose from, including DCI-P3, AdobeRGB, sRGB, DICOM, and BT.709.
The small camera-like sensor in the corner of the touchpad had me scratching my head until I realized it’s a built-in color calibration tool. You can set what color gamut you’re working in, close the lid of the laptop, and let it calibrate itself. That’s an awesome feature, especially for those who can’t just calibrate for one gamut and leave it be.
Professionals who require accurate color reproduction should have no issues with the DreamColor display, but there are other options if it’s not quite what you’re looking for. There are more options available for the ZBook 15 — as low as FHD with 250 nits brightness — but the ZBook 17 also has some budget options. For extra privacy, the 15-inch ZBook has an optional Sure View finish that blocks the view of anyone who’s not looking directly at the display.
Performance and battery life

Coupled with Intel Xeon E-2286M vPro CPUs with eight cores, up to 128GB of RAM spread out over four modules, and up to 10TB of storage (15-inch model tops out at 6TB), you should have no problems getting the right amount of power for the task at hand. Independent Software Vendor (ISV) certifications are included for popular design and development programs, ensuring the laptop is compatible.

Dual fans in each laptop keep internals at a suitable temperature. Even under sustained load while benchmarking the ZBook 17 was surprisingly quiet and didn’t suffer from any significant throttling. The ZBook 15’s fans seemed to work a bit harder, no doubt due to the smaller chassis, but fan volume still wasn’t egregious.
I ran some benchmarks on both the ZBook 15 and ZBook 17 to see how they stack up against each other as well as some other laptops we’ve recently reviewed.

The M.2 PCIe NVMe SSDs included are extremely fast. I also tested with PCMark’s Storage test and got back a score of 1,657 in the ZBook 17 and 2,471 in the ZBook 15.
PCMark’s gaming battery test, which measures battery life with the system under relatively heavy load, measured just an hour and 15 minutes. Going about normal work, you should expect between five and six hours of life from a charge. Note that I tested rather high-end models with 4K displays, and less-powerful configurations with FHD display will have far better battery life.
Unfortunately, I couldn’t run the same test on the ZBook 15 due to a battery issue; the laptop wouldn’t run without the AC adapter. It might make you question durability but it’s just something that happens and is covered by warranty if support options don’t solve the problem.
Should you buy HP’s ZBook 15 or ZBook 17?

Toolless entry on the bottom panel is an ingenious addition, the top-firing speakers are excellent, and you get plenty of ports for connecting your peripherals, including something like HP’s Reverb VR headset. I don’t quite like the keyboard as much as I do on a ThinkPad, but it’s still going to make typing comfortable.
Answering the “Should you buy?” question ultimately comes down to whether or not you need the performance and features and can afford the steep price tag. Want up to a NVIDIA Quadro RTX 5000 GPU and larger display that makes collaboration much easier? Go with the ZBook 17, though keep in mind it’s much better suited to life on a desk than in a backpack due to its size and weight.
Can you get by with up to a NVIDIA Quadro RTX 3000 GPU and smaller 15-inch display? The ZBook 15 is likely a better (and more affordable) choice, plus it’s much easier to carry around. It won’t have a Mini DisplayPort or an optical drive, but it does a much more convincing job of acting as a portable laptop.
