MagyarHP ZBook Studio G5 (i7, P1000, 4K) Workstation Review
"ZBook" – this brand name is not very old. Since 2013, HP's mobile workstations bear this name; before, they were part of the EliteBook laptop series. Since then, ZBooks have established themselves in the workstation sector and HP has continued to expand the line. In 2015, the manufacturer added the first HP ZBook Studio to the line, complementing more classic workstations like the ZBook 15 G3 and the ZBook 17 G3. The new ZBook Studio G3 was different from the existing ZBooks since it combined a slim chassis design with very powerful processors of the Intel Core H-series.
In 2018, HP released the third generation of the ZBook Studio. The new model ZBook Studio G5 is a complete redesign from its predecessor, the HP ZBook Studio G4, a complete redesign. Also, for the first time, the ZBook Studio is now available in a multimedia-version, which is carrying the brand HP EliteBook 1050 G1. The biggest difference between the EliteBook and the ZBook is the different GPU The chassis design is, apart from the slightly darker ZBook-color, identical. That is why we point to the review of the HP EliteBook 1050 G1 for detailed information on the chassis, the connectivity and the input devices.
HP, Dell and Lenovo constitute the "Big Three" of the PC market. These manufacturers dominate the workstation sub-market as well, which points to the Dell Precision 5530 and the Lenovo ThinkPad P1 as the main competitors to the ZBook Studio G5. The Apple MacBook Pro 15 2015 also serves a similar customer group as the ZBook Studio, even though it is more of a multimedia than a workstation laptop. HP also makes a machine that is pretty similar to the ZBook Studio G5 in some way, which could also be considered to be a competitor: The ZBook 15u G5 is a thinner workstation as well, which differentiates itself from the ZBook Studio G5 through the use of lower-voltage processors.
Our review-unit contains the Intel Core i7-8750H, a 512 GB SSD, 16 GB RAM, a 4K UHD display and the Nvidia Quadro P1000. This configuration costs roughly €2,500 in Germany and roughly $2,300 in the USA.

Display
There are a number of different 15.6-inch screen options. Our review-unit for example sports a matte 4K UHD (3,840 x 2,160) screen, but the ZBook Studio is also available with a matte FHD (1,920 x 1,080) screen with 400 cd/m². Additionally, there is a matte 4K UHD panel, which sports the 'Dreamcolor' name. This LCD is supposed to be exceptionally bright (600 cd/m²) and colorful (100% AdobeRGB). These are the three display options that are available right now. In the spec-sheet, HP lists a glossy FHD screen with the 'SureView' privacy-filter and 650 cd/m² brightness. All offered LCD panels are based on IPS technology.
The non-Dreamcolor 4K UHD panel in our unit is supposed to hit 400 cd/m² of brightness according to HP. It certainly does reach this level of brightness and even manages to exceed it with an average brightness of 412 cd/m². This means that the used LCD panel by AUO is brighter than the nominally identical AUO screen in the HP EliteBook 1050 G1 – another example for the always-popular variance in part quality.
Compared with the competition, the display performs well enough in terms of brightness. The LCD panels used in the Dell Precision 5530 and Apple MacBook Pro 15 2018 are brighter, but the screen of the Lenovo ThinkPad P1 is slightly darker. If users wish for an even brighter panel, one must not forget that HP also offers the Dreamcolor screen as an option.
There was no notable PWM; the same is true for backlight bleeding. The brightness distribution of 85% is acceptable. With the naked eye, no dark spots were visible.

* ... smaller is better
There are some deviations when it comes to colors. With a calibration, these deviations, which can be summarized as a blue-tint, can be quickly eliminated. By using the ICC profile we created, the screen displays colors relatively correctly. The contrast-value amounts to 1438:1, thanks to the combination of the high brightness and a low black-value (0.29 cd/m²). Only the 4K UHD LCD of the Lenovo ThinkPad P1 offers a higher contrast.
When it comes to color gamut, the display covers 96% of the sRGB color space. This means that the LCD can show enough colors to make semi-professional photo editing possible. If an even better color-space-coverage is needed, HP still has the Dreamcolor panel up its sleeve.
Screens with a brightness-value of over 400 cd/m² are usable outdoors in principle, no matter if the surface is matte or glossy. In this case, the matte surface is a positive bonus, as it eliminated annoying reflections. The brightness combined with the matte surface should even enable the usage of the ZBook Studio G5 in indirect sunlight.

Performance
HP offers the ZBook with a number of different Intel CPU options: Two i5 processors (Core i5-8300H & Core i5-8400H), two i7 processors (Core i7-8750H & Core i7-8850H), two Xeon CPUs (Xeon E-2176M & Xeon E-2186M) and the Core i9-8950HK. Theoretically, there should also be a choice when it comes to the dedicated GPU, but in reality, only the Nvidia Quadro P1000 is available. Admittedly, the Nvidia Quadro P2000 is listed in the spec-sheet, but it is simply not available. This means that there is no upgrade, though a GPU-downgrade is possible: The ZBook can be ordered without a dGPU, in which case the Intel UHD Graphics 630 takes care of the graphics.
In terms of RAM, there are options to order the ZBook with either 8, 16 or 32 GB DDR4-2666-RAM, optionally on the Xeon models as ECC RAM. With the RAM sockets, the ZBook can be upgraded to a maximum amount of 64 GB. Additionally, the ZBook has two M.2 2280 slots for SSDs as well, so it is a very upgradeable machine. Ex factory, the HP laptop can be configured with 256 GB, 512 GB, 1 TB or 2 TB.
Processor
The Intel Core i7-8750H is one of the most used processors of the Coffee Lake H series, which includes very powerful CPUs with a TDP of 45 W. In the case of the i7-8750H, there are six CPU cores, which make this CPU a hexa-core chip. Those cores have a clock-speed-range of 2.2 to 4.1 GHz.
This maximum turbo-boost is not reached in the Cinebench multicore loop. Instead, the CPU cores can achieve 3.9 GHz and hold that clock-speed for 30 seconds, consuming 60 W while doing so. After 30 seconds, the consumption is limited to 45 W, which means that the CPU works with 3 GHz. In the 30-minute long loop, this power level can be retained for the remainder of the test, the higher performance-level of 3.9 GHz is only achievable in the very first iteration of the test.
Compared with the competitors Dell Precision 5530 and the Lenovo ThinkPad P1, the ZBook Studio G5 achieved roughly the same level of performance. Under sustained load, the HP notebook delivered the lowest performance on average, but the difference is pretty small. Overall, the CPU performance of the ZBook Studio G5 is very good. However, CPU upgrades beyond the Core i7-8750H will most likely not result in an increased multicore-performance. The cooling system is already working to capacity here.
While using the ZBook without an attached charger, the CPU performance is reduced. Instead of 1100 points, the ZBook Studio G5 just reaches roughly 950 points in the Cinebench R15 multicore test.
System Performance
In the PCMark-benchmarks, the ZBook Studio G5 places itself at the end of the ranking, though in everyday use, the system performance was not bad. On the contrary, the system always ran smoothly.

Storage
HP does not cheap out when it comes to the SSD: The American manufacturer uses the Samsung PM981 with a capacity of 512 GB. This PCIe NVMe SSD in the M.2 format is extremely fast and showed no weaknesses in the benchmarks.

GPU
The Nvidia Quadro P1000 is a CAD-optimized GPU of the lower middle-class. More detailed comparisons with other GPUs are possible with our GPU benchmark-list.
It is not surprising that the Quadro P1000 is slower than the Quadro P2000. The Max-Q version of the Quadro P2000 is faster in all benchmarks as well. More interesting is the comparison with the Nvidia GeForce GTX 1050 Max-Q, which is used in the almost identical HP EliteBook 1050 G1. The Quadro P1000 is 15 to 20% slower than the Nvidia GeForce GTX 1050 Max-Q in the 3DMark-benchmarks. In the LuxMark test, the consumer GPU is also clearly faster.
The GPU performance is not limited when the machine is running on battery.

Gaming Performance
Gaming is certainly not the specialty of a workstation, but a little bit of fun with a game after a long day of work is not necessarily a bad thing. The Quadro P1000 offers a basic ability to play modern games. However, it should be noted that games that are more recent would not be playable with the maximum details or in 4K UHD. Compared with the GeForce GTX 1050 Max-Q in the EliteBook 1050 G1 , the GeForce easily beats out the Quadro when it comes to playing games, because it simply offers more performance overall.
The performance that the Quadro P1000 does offer is available even under continuous load, which is what our Witcher 3 loop shows.

Emissions
System noise
While idling, the active cooling system, which consists of two fans in the ZBook Studio G5, is most often deactivated. If the fans come on, they are louder than the Lenovo ThinkPad P1 fans, but quieter than the EliteBook 1050 G1 and ZBook Studio x360 G5 cooling systems. Under load, the cooling system is constantly active, but the fan-noise is not extremely loud. One thing to note is that the noise, overall, is lower frequency when compared with the EliteBook 1050 G1. Probably, HP is using different fans from multiple parts manufacturers.
Like so many laptops, the ZBook Studio G5 suffers from electronic noise. Though it is not very loud; to hear it, one must hold an ear directly next to the keyboard.

Temperatures
The temperatures are hovering around a similar level as they do on the ZBook Studio x360 G5. The outer temperatures are even lower. With a maximum temperature of 43.1 °C (~110 °F), it is hard to claim that the temperatures are too high.
The stress test with Prime95 and FurMark proceeds almost exactly as it does with the convertible model: The processor can reach 3.9 GHz for short a amount of time, until the clock-rate goes down to 1.3 GHz. This happens, because the power consumption is now limited to 15 W. Different from the convertible x360 model, the CPU cannot occasionally ramp up its clock speed for short bursts in the later progression of the test. Instead, the CPU performance stays on a low level. Meanwhile, the GPU can hold its maximum performance level with some minor deviations for the whole course of the test. The follow-up 3DMark11 resulted in a score on the normal level, which means that the throttling in the stress test is of little importance for everyday use.
(±) The maximum temperature on the upper side is 42.3 °C / 108 F, compared to the average of 38.1 °C / 101 F, ranging from 22.2 to 69.8 °C for the class Workstation.
(±) The bottom heats up to a maximum of 43.1 °C / 110 F, compared to the average of 41.3 °C / 106 F
(+) In idle usage, the average temperature for the upper side is 23.2 °C / 74 F, compared to the device average of 32 °C / 90 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 34.8 °C / 95 F, compared to the device average of 32 °C / 90 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 29.6 °C / 85.3 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.8 °C / 82 F (-1.8 °C / -3.3 F).
Speakers
HP puts the speakers between the keyboard and the hinges. They are marked with the "Bang&Oluflsen" logo and they are user facing, different from speakers of the Lenovo ThinkPad P1 or the Dell Precision 5530. Those machines have speakers at the bottom of the system, which could sometimes impair sound quality. For a laptop, the speakers of the ZBook Studio G5 are pretty good. Their quality is better compared with the ThinkPad P1 and pretty much on the same level as the Precision 5530; though their positioning definitely gives a small advantage to the ZBook over the Precision as well.
The combo audio port worked flawlessly and offered a very good alternative to the speakers, as always.

Power Management
Power consumption
The competitors by Lenovo and Dell perform much worse when it comes to the energy consumption. The ZBook just runs with less power consumption, especially when idle. The comparison is most unfavorable for the Dell Precision 5530. Some machines do consume less energy than the ZBook Studio G5 though, this includes the Apple MacBook Pro 15, the HP EliteBook 1050 G1 and especially the ZBook 15u G5. This last model needs less energy thanks to the usage of energy-saving ultra-low-voltage processors. More interesting is that the HP EliteBook 1050 G1 consumes less energy, because it is almost equipped identically to the ZBook Studio G5. Probably, drivers make the difference in this case.
The charger supplies 150 W, more than enough for the maximum power consumption of 126 W.

Battery life
With its internal 97 Wh battery, the HP ZBook Studio G5 delivers a convincing result. In the Wi-Fi test, the ZBook almost managed 10 hours, more than an hour longer than the Dell Precision 5530. The Lenovo ThinkPad P1 performs even worse, thanks to its much smaller battery. Better in this respect is only the Apple MacBook Pro 15, because of its lower power consumption.

Verdict
Pros
Cons
The HP ZBook Studio G5 managed a good showing in our review – that is why it scored 87% and the grade "good". It shares most of its best features with the EliteBook 1050 G1.
Certainly this is not a big surprise, considering that the ZBook Studio uses the same stable Unibody chassis as the EliteBook 1050 G1 – just in gray instead of silver. Also identical: The comfortable keyboard, the big battery, the port selection, the commendable upgradeability, the great CPU performance and the touchpad. Our review unit even uses exactly the same AUO LCD panel as its EliteBook twin. The difference is less obvious at first glance: Most important is the different GPU – while the ZBook uses the CAD optimized Quadro P1000, HP utilizes the faster Nvidia GeForce GTX 1050 Max-Q in the EliteBook. This leaves the ZBook at a disadvantage in terms of GPU performance, at least until its Quadro P2000 configurations are available. Apart from that, it should be noted that only the ZBook has the option for a Dreamcolor display, the EliteBook 1050 G1 is sadly not offered with this display.
The disadvantage in terms of GPU performance persists in the comparison with the Lenovo ThinkPad P1 and the Dell Precision 5530: Both are offered with the Quadro P2000, while the ZBook is not, at least at the moment. Additional negative points are shared with the EliteBook 1050. This includes the higher weight compared with the competition, the bad position of the fan exhausts and the performance throttling while running on battery. Last but not least, the ZBook Studio G5 is also a very expensive device.
Convincing: The ZBook Studio G5 is a solid mobile workstation with few weak points.
Overall, the ZBook certainly has earned a recommendation from us. If it is to be preferred over the Lenovo ThinkPad P1 or the Dell Precision 5530 is a question of the taste and feature requirements.
