HP says its ZBook 15 is the world's best-selling mobile workstation.
At a glance, the G6 model seen here (starts at $2,210; $4,096 as tested) doesn't look very different from the G5 we reviewed in November 2018—its aluminum chassis measures the same 1 by 14.8 by 10.4 inches and weighs the same 5.8 pounds, with the same thick bezels around the 15.6-inch screen and the same layout of ports on the sides.
Under the hood, however, the ZBook 15 has acquired VR-ready graphics in the form of Nvidia's 6GB Quadro RTX 3000 and stepped up from a six-core CPU to an eight-core Intel Xeon E-2286M.
Its dazzling 4K DreamColor display, which formerly offered 100 percent coverage of the AdobeRGB color gamut, now covers 100 percent of the DCI-P3 space to rival the 16-inch Apple MacBook Pro.
The HP G6 doesn't unseat the Lenovo ThinkPad P53 as our Editors' Choice, because it's only the second or third fastest mobile workstation we've tested.
But it's a robust, beautifully engineered system and a fine choice for design, rendering, and engineering professionals.
A Sizable Slab
The ZBook 15 is a bit bigger and heavier than the ThinkPad P53 (1.2 by 14.9 by 9.9 inches, 5.5 pounds) and much bulkier than the MacBook Pro (0.64 by 14.1 by 9.7 inches, 4.3 pounds).
It's passed no fewer than 21 MIL-STD tests against shock, vibration, temperature extremes, and other road hazards; there's virtually no flex if you grasp the screen corners or press the keyboard deck.
The $2,210 baseline model at HP.com combines a six-core Core i7-9750H processor with Nvidia's Quadro T1000 (though you can dial it down all the way to a Core i5-9300H and Intel integrated graphics, which doesn't qualify as a workstation in our eyes).
Naturally, my test unit's $4,096 price tag elevated everything on the spec sheet, from the 2.4GHz (5.0GHz turbo) Xeon E-2286M and Quadro RTX 3000 to 64GB of memory and a 1TB NVMe solid-state drive.
The memory ceiling is a hefty 128GB of standard or, for Xeon machines, 64GB of ECC DRAM.
Two M.2 slots and one 2.5-inch drive bay allow up to 6TB of storage.
The 4K (3,840-by-2,160-pixel) DreamColor panel is the top screen choice; it's a non-touch display that boasts a billion colors and 600 nits of brightness, though it uses conventional IPS technology instead of the ultra-contrasty OLED design available on the Lenovo.
You can also get non-DreamColor 4K displays in either touch or non-touch flavors, or one of three 1,920 by 1,080 panels including a touch screen with HP's SureView privacy feature.
The latter toggles a filter that narrows the viewing angle to discourage your airline seatmate from sneaking a peek at your spreadsheet financials.
On the laptop's left side, you'll find two USB 3.1 Type-A ports (one with device charging) plus an Ethernet port, an SD card slot, and a security lock slot.
There's a third USB 3.1 Type-A port on the right, along with two Thunderbolt 3 ports, an HDMI port, an audio jack, a SmartCard slot, and the AC adapter connector.
Bluetooth and 802.11ax (Wi-Fi 6) wireless are standard; AT&T or Verizon LTE mobile broadband is optional.
Ready for Tremendous Tasks
The ZBook offers both a fingerprint reader and face recognition webcam to skip passwords for Windows Hello logins.
The webcam captures images in 1080p instead of the usual 720p resolution, which is a plus, but they look a bit harsh and grainy.
A sliding shutter covers the lens if you're concerned about online snoops.
Stereo speakers mounted above the keyboard can easily fill a room with sound that's crisp and not distorted even with volume cranked to the max.
Bass and treble are both surprisingly strong, and you can distinguish overlapping tracks with no trouble.
A Bang & Olufsen Audio Control utility lets you select music, movie, and voice presets or play with an equalizer.
Two gripes about the ZBook 15 G6's keyboard: The Escape, Delete, Home, End, Page Up, and Page Down keys are puny, and the cursor arrow keys are arranged in HP's eternally awkward row instead of the proper inverted T (with hard-to-hit, half-height up and down arrows stacked between full-height left and right arrows).
On the positive side, there are collaboration keys for sharing your screen and starting or hanging up on Skype calls.
The F6 key mutes the microphone if you'd rather lurk and listen.
Typing feel is comfortable, with clicky, snappy feedback.
For cursor control, there's both a pointing stick and a touchpad, each with three buttons including the middle button beloved of the independent software vendor (ISV) applications for which the ZBook is certified.
The touchpad glides and taps smoothly and the buttons have a soft, springy feel.
I've been wowed by HP's DreamColor screens before, and the G6's is no exception.
It's a matte anti-glare panel with ample brightness and deep contrast.
Fine details are razor-sharp and colors are richly saturated.
A DreamColor Assistant widget in the Windows taskbar lets you choose among DCI-P3, AdobeRGB, sRGB, DICOM, BT.709, or native color profiles; create and reset custom profiles; or recalibrate the display by closing the lid and waiting for a sensor in the touchpad to signal that color has been fine-tuned.
In addition to Windows 10 Pro for Workstations, the ZBook carries a slew of security and management utilities ranging from Intel's vPro to HP's Sure Start (which keeps malware from modifying the BIOS), Sure Click (an extra layer of browser protection), Sure Recover (operating system image recovery over a network), and Sure Sense (a new AI-based tool that battles zero-day threats and ransomware).
World-Class Workstation Performance
For our performance benchmarks, I pitted the ZBook 15 G6 against two other 15.6-inch mobile workstations, the Dell Precision 5530 and Editors' Choice Lenovo ThinkPad P53, and two speedy 17.3-inch entries, the MSI WS75 and HP ZBook 17 G5.
You can see their basic specs in the table below.
All these systems, very much including the G6, are built to annihilate tough computer-aided design (CAD) or scientific jobs—they're grotesque overkill for Microsoft Office or Google Docs—and to keep chugging day and night on big rendering projects.
The 15.6-inch HP led the way in several tests, though not the workstation simulation we value most highly.
Productivity, Storage, and Media Tests
PCMark 10 and 8 are holistic performance suites developed by the PC benchmark specialists at UL (formerly Futuremark).
The PCMark 10 test we run simulates different real-world productivity and content-creation workflows.
We use it to assess overall system performance for office-centric tasks such as word processing, spreadsheeting, Web browsing, and videoconferencing.
The test generates a proprietary numeric score; higher numbers are better.
PCMark 8, meanwhile, has a Storage subtest that we use to assess the speed of the system's storage subsystem.
The result is also a proprietary numeric score; again, higher numbers are better.
Four thousand points is a sensational score in PCMark 10, so using the G6 for Word or PowerPoint is like hiring the Hulk to help you vacuum under the bed.
The mobile workstations' solid-state drives sailed through PCMark 8's storage subtest.
Next is Maxon's CPU-crunching Cinebench R15 test, which is fully threaded to make use of all available processor cores and threads.
Cinebench stresses the CPU rather than the GPU to render a complex image.
The result is a proprietary score indicating a PC's suitability for processor-intensive workloads.
The six-core systems easily cleared the 1,000-point line that indicates a video editing or 3D rendering powerhouse, while the eight-core MSI WS75 and ZBook 15 G6 soared higher still.
Not even VR content creation can slow them down.
We also run a custom Adobe Photoshop image-editing benchmark.
Using an early 2018 release of the Creative Cloud version of Photoshop, we apply a series of 10 complex filters and effects to a standard JPEG test image.
We time each operation and, at the end, add up the total execution time (lower times are better).
The Photoshop test stresses the CPU, storage subsystem, and RAM, but it can also take advantage of most GPUs to speed up the process of applying filters, so systems with powerful graphics chips or cards may see a boost.
The HP G6, Lenovo, and MSI tied for the win.
Between its speed and spectacular screen, the ZBook is a marvelous platform for photo editing.
Graphics Tests
3DMark measures relative graphics muscle by rendering sequences of highly detailed, gaming-style 3D graphics that emphasize particles and lighting.
We run two different 3DMark subtests, Sky Diver and Fire Strike, which are suited to different types of systems.
Both are DirectX 11 benchmarks, but Sky Diver is more suited to laptops and midrange PCs, while Fire Strike is more demanding and made for high-end PCs to strut their stuff.
The results are proprietary scores.
Next up is another synthetic graphics test, this time from Unigine Corp.
Like 3DMark, the Superposition test renders and pans through a detailed 3D scene and measures how the system copes.
In this case, it's rendered in the company's eponymous Unigine engine, offering a different 3D workload scenario than 3DMark, for a second opinion on the machine's graphical prowess.
We present two Superposition results, run at the 720p Low and 1080p High presets.
These scores are reported in frames per second (fps), the frequency at which the graphics hardware renders frames in a sequence, which translates to how smooth the scene looks in motion.
For lower-end systems, maintaining at least 30fps is the realistic target, while more powerful computers should ideally attain at least 60fps at the test resolution.
While these systems can certainly play games, these benchmarks are really optimized for gaming GPUs like Nvidia's GeForce rather than Quadro series.
The 15.6-inch HP showed good but not great results, finishing near the back of the field.
Workstation-Specific Tests
In addition to our CPU measurement, Cinebench R15 has an OpenGL exercise that uses that popular vector graphics application programming interface (API) to tap the GPU for hardware-accelerated rendering of a brief animated movie of a car chase.
Results are displayed in frames per second (fps); higher numbers are better.
We also use the POV-Ray 3.7 benchmark.
The Persistence of Vision Raytracer is a free software program that makes tons of floating-point calculations to determine pixel colors and (optionally) put them on screen.
It exercises CPU cores and threads and the FPU much more than even a workstation-style GPU, let alone the 3D graphics cards in most gaming PCs.
The benchmark times (in seconds; lower is better) the off-screen rendering of a photo-realistic scene with multiple light sources.
The ZBook 15 G6 did very well here, slugging it out with the ThinkPad P53 for second place behind the MSI in Cinebench OpenGL and finishing in a dead heat with the WS75 for the gold medal in POV-Ray.
Finally, there's SPECviewperf 13, the most realistic and challenging workstation benchmark we run and the one we give greatest weight.
This test uses viewsets from actual ISV apps to render, rotate, and zoom in and out of wireframe and solid 3D models, with results listed in frames per second (higher is better).
The viewsets we use are from PTC's Creo CAD platform; Autodesk's Maya modeling and simulation software for film, TV, and games; and Dassault Systemes' SolidWorks 3D rendering package.
The HP G6 put up fine numbers in these tests, easily thrashing the Dell Precision 5530 and satisfying even demanding creative professionals.
But it was also next to last overall; the Lenovo and its mighty Quadro RTX 5000 handled the ZBook with one hand tied behind its back.
Battery Rundown Test
After fully recharging the laptop, we set up the machine in power-save mode (as opposed to balanced or high-performance mode) where available and make a few other battery-conserving tweaks in preparation for our unplugged video rundown test.
(We also turn Wi-Fi off, putting the laptop into airplane mode.) In this test, we loop a video—a locally stored 720p file of the Blender Foundation short film Tears of Steel—with screen brightness set at 50 percent and volume at 100 percent until the system conks out.
Taking the Precision and the ZBook 17 as outliers, the other mobile workstations performed roughly as expected—capable of a short trip from a desk or render farm to a conference room or client's office, but never asked to deliver an unplugged workday the way ultraportables or lightweight convertibles are.
Their relatively brief battery lives aren't deal-breakers.
A Workflow Thoroughbred
HP will probably be disappointed that the ZBook 15 G6 doesn't steal our mobile workstation crown from the ThinkPad P53, but it's only fair to note that our P53 test unit was priced $900 higher despite having two fewer processor cores and a 1080p rather than 4K display.
And though the HP's scores in our SPECviewperf benchmark were just a bit off the pace, it absolutely blazed through our other tests.
The ZBook may have unfashionably fat screen bezels, but its screen can't be beat by anything in its class.
Its memory and storage capacity is colossal.
Its user-serviceable design is tops (a sliding latch lets you remove a bottom panel for access to the battery, hard drive bay, SSD slots, and two of the four memory sockets).
If you're looking for a formidable 15.6-inch workstation, you can't afford to overlook the HP.
Pros
Gorgeous 4K DreamColor screen with color calibrator.
Beefy eight-core Xeon CPU.
Room for tons of memory and storage.
VR-ready Nvidia Quadro RTX 3000 graphics.
