Who are the most demanding and powerful notebook users? Some would say the players, but we would like the users of mobile workstations or scientific professionals who want machines that are not only fast, but sustainable, supported by the certifications of independent software vendors (ISVs) and compatible with the elite applications. Complex data sets and visuals. The HP ZBook 15 G4 (starting at $ 1,847.78, $ 3,181 as tested) is such a system. As the fourth generation of the 15.6-inch main product, the ZBook 15u novice dual-core and ZBook Studio are placed thinner and lighter.
The test unit includes a quad-core Intel Xeon E3-1505M v6 “Kaby more” 3 GHz, 32 GB memory DDR4 ECC one PCIe SSD 512 GB, Nvidia Quadro graphics card and M2200 1,080) IPS screen. These components helped him surpass the forerunner of its publisher, the Dell Precision 5000 Series 15 (5510) 1 $ 279.00 at Dell, in our benchmarks under, but not a maximum configuration: the ZBook can be configured at the control time with up to 64 GB of RAM and up to 3 TB of storage (two SSD and M.2 1 TB SATA 1 TB and 2.5 inches). In fact, because – unlike in 5510 – the frame is not waterproof, you can unscrew the bottom panel and install a hard drive even larger, but an HP representative said the company is putting an external Thunderbolt archive in place of 3 then are officially approved 3 TB to exceed.
The display of our system is not the best: a touchscreen Full HD and 4K screen (3840 x 2160) with DreamColor calibration HP and the management of color space, and a Xeon E3 -1535M v6 faster (or, if you have a few cents pinches, a Core i7 or Core i5 processor).
Two-tone style, Thunderbolt speed
The aluminum and magnesium frame of the ZBook 15 G4 has a beautiful inlaid lid with a large HP logo in two shades of gray. A thin chrome band surrounds the three sides of the system and the words “Mobile Workstation” appear on the back. At 5.8 pounds, it’s heavy enough for a laptop without touch screen or optical drive (compare Apple MacBook Pro 15-inch to 4.0 pounds, or the Dell Precision 3.520-4.8 pounds), and much more of only a backpack up to 1.0 by 15.2 by 10.4 inches (HWD, compare the HP ZBook Studio G4 by 0.71 by 14.76 by 10.04). The laptop has passed MIL-STD tests to survive shock and harsh conditions; there is some flex in the keyboard drawer, but none on the screen.
The choice of port is more than sufficient, ranging from modern (two Thunderbolt ports 3 with DisplayPort functionality and USB-C) with classic (VGA port). Other interfaces include three USB 3.0 ports, SD and SmartCard housing and HDMI ports, audio and Ethernet, and a Kensington lock and connection for the AC adapter brick format.
The centered webcam above the screen captures detailed, well-lit images and videos; there is a mute microphone button (Fn + F10) to listen to online conferences. The speakers at the front of the system pumping a pretty good sound, a bit quieter than others – loud enough to fill a room, but not to vibrate the walls – and on the basses, but with highs and well defined stockings.
Although we were disappointed that our test unit did not display the 4K DreamColor HP screen (an option of $ 320), the screen belongs to the best 1080p panels we’ve seen. The brightness is sufficient, although only in the first two or three settings of backlighting, and the contrast is excellent, with deep black and impeccably white. PowerPoint slides, YouTube videos and SPECviewperf test processing templates all benefited from bright colors and wide viewing angles. (Avoid the SVA screen option in HP’s Online Configurator – it represents “standard viewing angles”, as opposed to the ultra-wide viewing angles of the IPS technology on our screen.)
We also love the ZBook backlit keyboard, with the exception of the great arrowheads on the HP brand – half-sandwiched between left and right; would that kill HP to use the reverse T-arrangement that almost every other laptop vendor uses? At least there are special keys for Home, End, Page Up and Page Down, even if these and the Delete key are small.
Two buttons just above the keyboard switch between Wi-Fi and mute sound, and a Windows Hello compatible fingerprint reader is located under the keyboard. The typing feeling is good, with a deep movement and a slightly elastic feedback. we made a few mistakes in our first few minutes, but we went to work quickly. The touch-sensitive touchpad and keyboard-mounted pointing device offer three buttons, including the middle button used by some desktop applications. HP bundles the ZBook with its external graphics software, which allows a low-power PC or tablet to access the screen of the powerful workstation via the Internet.
Overkill for Office
Both crashed the Precision 5510, but the ZBook 15 G4 on the Xeon outperformed the Dell Precision 3520 999.00 at Dell (from 3,601 to 3,539 points) in our PCMark 8 benchmarks for overall productivity. machines too powerful to waste with a simple diet of spreadsheets and word processing documents; As we said, these mobile workstations are suitable for demanding applications, such as editing and video coding, with the ZBook recording a rare sub minute (57 seconds) in our bench Handbrake test. Preferred business notebook, the Lenovo ThinkPad T470 $ 783.20 at Lenovo (2:04). The only one in the team for the best in this test was his nephew, the ZBook Studio G4 (44 seconds).
The HP Mobile Workstation also shone in our Adobe Photoshop editing test, as the only one of our test group to complete the workload in less than 3 minutes (2:43), against 3:01 for the Dell 5510 and 3:15 for the Apple MacBook Pro $ 2,399.00 at the Apple Store. And even though it’s designed for work, not for gaming, it shines through our Heaven and Valley game simulations and reaches the 30 frames per second threshold for smooth gameplay, even in the best picture settings.
The ThinkPad T470 and the optional long-life battery were at the forefront of our battery test, which lasted more than 17.5 hours, with the 15 hours of the MacBook Pro not far behind. The ZBook 15 G4 has just dropped in the middle of the package, but its time of 11 hours and 15 minutes is more than enough to work a day.
Ready for everything
Apart from the mass and the arrow keys, it is difficult to find an error in the ZBook. It is expensive, but the type of users that invest in powerful mobile workstations will find it can repay itself on a few jobs. It offers exceptional performance and battery life, as well as all the connectivity you can ask for. It is even supported by a three-year warranty with on-site service.
Last year we presented our editors to the Precision 5510, partly because of the great 4K touchscreen that the HP cannot match – the available 4K screen is not a touchscreen. But the quasi-scan benchmark test, greater scalability and the second Thunderbolt 3 port make us stand out in the ZBook 15 G4.
