MagyarHP EliteBook 855 G7 Laptop Review - Stylish office laptop for on the go
The HP EliteBook 855 G7 is a high-quality office laptop from HP's EliteBook 850 series, with '855' identifying the AMD model. Our test device wants to stand out from the Intel competition with a slightly higher graphics and multi-thread performance. The EliteBook 855 G7 makes a great first impression with its elaborate design and the stylish case. The recommended retail price for our configuration is around 1,465 Euros (~$1753). Thus, the laptop plays in a price range in which Dell, Lenovo and Acer also have a lot to offer.

Case - Slim Business Laptop
The housing is completely made of metal and makes a good first impression. The choice of material also benefits the haptics and case stability. The base unit of the laptop is very difficult to twist and the lid also looks robust. The hinges are also solid and hold the display well at all opening angles. The angular design and certain optical accents, such as the pattern in the volume perforation or the light gray EliteBook lettering, show that this is by no means a budget notebook. Accordingly, there are no material protrusions or unequal gap dimensions. The front edge is not flat, but slightly angled to make it easier for users to open the laptop. However, the hinge is too rigid or the base unit is too light to open the laptop with one hand.
With a width of around 360 mm (~14.2 in), the EliteBook 855 G7 is relatively small and its total weight of only 1.7 kg (~3.8 lb) makes it the lightest laptop in our comparison. The more expensive Dell XPS 15 9500 is even more compact, while the ThinkPad L15 weighs a good 200 g (~7 oz) more at 1.9 kg (~4.2 lb).
Features - No card reader and no LAN connection
Although most connectors are located in the rear area on the left and right side of the laptop, wider connectors should not block adjacent connectors. Like many slim laptops, the EliteBook 855 G7 does not need a LAN port, but thanks to the full-size HDMI 2.0 port and two USB-A and two USB C ports (the latter with DisplayPort and charging function), it is relatively flexible. Furthermore, both USB-C ports of the Intel variants (EliteBook 850 G7) support Thunderbolt.
Despite the USB-C power supply unit included in the delivery, the EliteBook also has a hollow plug connection, which can also be used to charge the notebook. Since most competitors can also accept at least microSD cards, it is strange that there is no card reader at all.
Communication
Intel's widely used AX200 is used as a WLAN module and also offers Bluetooth 5 support. In the test, it usually beats other office laptops, but the built-in AX200 module achieves below-average values both when sending and receiving data via WLAN, which are also relatively far below those of the comparable devices. The performance is still sufficient for everyday use, especially since the transmission performance is very constant. HP also offers models with WAN as an option.
Webcam
Security
Security features include a fingerprint scanner, smart card reader, TPM 2.0, IR camera for Windows Hello and various software security solutions from HP.
Accessories
Except for the notebook itself and some manuals there are no extras included. In its own online store, the manufacturer offers, for example, a WWAN LTE module for retrofitting and a 65 W hollow plug power supply unit, with which you can buy another free USB-C port for around 80 Euros (~$96) in mains operation.
Maintenance
When removing the base plate, our test device turned out to be particularly stubborn, and even after many attempts it could not be removed. So the maintenance options here are not really user-friendly, which for example makes upgrading the RAM or the SSD unnecessarily difficult. In principle however, both RAM slots and the SSD are accessible. A maximum of up to 32 GB DDR4 RAM is supported.
Warranty
HP grants buyers of the EliteBook 855 G7 a three-year warranty. In addition, there is an optional warranty extension for about 98 Euros (~$117), with which you can get hardware support on the next working day in case of problems on site.
Input devices - HP notebook with improved keyboard
Keyboard
The chiclet keyboard in the middle of the base unit contains a number pad and is located in a slightly lowered rectangle. This looks great, but the nice look has its price: The keys of the top row of keys and the arrow keys are only about half as high as the other keys. This doesn't matter much for the less frequently used function keys, but the operation of the arrow keys suffers.
The keyboard of our test device has a two-stage key illumination and indicator LEDs, which among other things signal the current status of the lock key. The key feedback is ok, but partly cheaper laptops, like the ThinkPad L15, which is designed for typing, also offer considerably more comfort when typing. When using the keyboard, the keys produce quiet but audible typing noises. The keyboard surface hardly gives way at all due to the metal construction. According to HP, it also withstands splash water.
Touchpad
The touchpad (12x6.5 cm/~4.7x2.6 in) is located slightly to the left under the keyboard. To encourage the use of the TrackPoint, HP has placed the two separate mouse buttons above the touchpad - this way, you don't have to change position while typing to operate the mouse. Mouse clicks can also be triggered on the ClickPad itself, with the lower right area serving as the right mouse button. The touchpad reacts quickly and precisely to input and the plastic surface has good sliding properties. Common multi-touch gestures are supported, which makes everyday operation easier.
Our model is not equipped with a touchpad, but corresponding models are also available.
Display - HP laptop with average display
The 15.6-inch IPS display has a native resolution of 1920x1080 pixels (Full-HD) and an aspect ratio of 16:9. Thanks to the matte panel, reflections are largely eliminated. HP also offers models with a 250 cd/m² FHD touchscreen, a 1,000 cd/m² FHD display with integrated HP Sure View privacy screen or a 400 cd/m² display with low power consumption. HP's Sure View technology is designed to greatly reduce viewing angles at the touch of a button to protect the screen content from prying eyes. Glossy screens are not currently available. The 1,000-cd/m² display is a particularly interesting option, which is well suited for outdoor use due to its high brightness.
Our configuration is equipped with the basic option and with measured values such as the average brightness of 234 cd/m², it does not trigger any storms of enthusiasm, or at least the use of PWM is avoided.

* ... smaller is better
The contrast ratio of 803:1 is the lowest in the comparison field, apart from that of the Acer TravelMate P2. The black value of 0.33, on the other hand, is in line with the average, which means that dark areas in films and photos can be displayed quite true to the original. The matte panel has no discernible effect on image sharpness.
The color space coverage of 62% (sRGB) and 40% (AdobeRGB) is in the midfield and is thus more than sufficient for everyday use, but the display is not suitable for professional video and image editing.
Outdoors, our configuration of the EliteBook 855 G7 is only of limited use, since the view is often severely restricted by the low brightness of only about 250 cd/m². In the shade, the display is mostly still readable thanks to the matte display. If you want to use the laptop frequently outdoors, you should take a look at the 1,000 cd/m² model, as this can compensate for ambient light even under more difficult conditions.

Performance - Low RAM capacity, high speed
Our configuration of the EliteBook 855 G7 is equipped with the AMD Ryzen 5 Pro 4650U and thus offers more than enough system performance for everyday office use. The Ryzen 5 Pro 4650U also includes AMD's integrated RX-Vega-6 graphics unit, which is way ahead of its Intel counterparts. The EliteBook models with Intel processors are called EliteBook-850-G7 and are equipped with the Intel Core i5-10210U or the more powerful Core i7-10510U. Although our test device is only equipped with 8 GB DDR4-3200 RAM in single channel mode and thus lies at the lower end of the spectrum, the size should still be sufficient for most office tasks due to the high speed. Configurations with 16 GB memory are also available. Dedicated graphics cards are not available within this model series.
Processor
The Ryzen 5 Pro 4650U is an AMD processor from the current Renoir generation. The six-core SoC clocks at 2.1 to 4.0 GHz and as an AMD Pro variant can process two threads per core thanks to SMT. In addition, the "Pro" chip offers some security and management functions compared to the AMD Ryzen 5 4600U.
In our Cinebench loop test, the Ryzen 5 Pro 4650 is far ahead of all Intel competitors. However, as a larger device with a more powerful processor, the ThinkPad L15 is even faster. The performance drops slightly at the beginning and then remains on a constant level.
In terms of program-specific performance, our EliteBook 855 G7 often lags behind in the single-threaded benchmarks, but it consistently ranks second in multi-threaded benchmarks, where only the more powerful ThinkPad L15 scores higher thanks to the Ryzen 7 Pro 4750U.
The EliteBook 855 G7 has a small lead over the Ryzen 5 Pro 4650U laptops tested so far, although these models are also 13 and 14 inch devices.
In battery mode the CPU performance is slightly limited.

System Performance
In the PCMark benchmarks, the EliteBook 855 G7 is in second place overall, largely due to its clear lead in the digital content creation benchmark. Together with the ThinkPad L15, it is a good 20 to 40% faster than the other comparable devices. This can probably often be explained by the higher graphics performance compared to UHD-based devices. On the ThinkPad T15, which is equipped with the GeForce MX330, the slower DDR4-2666 RAM could be a reason for the lower score. In everyday use, the laptop reacts quickly to input and implements it immediately.

Mass storage - Scarce 256 GB
Buyers of our test configuration have to come to terms with just 256 GB of storage space. The performance of the SK Hynix BC511 is below average in the comparison field. Even the 512 GB variant of the SSD installed here achieves an approximately 26% higher performance in the Dell Latitude 15 5510. Such differences in performance are not uncommon with differently sized SSDs within the same model series. Overall, only the Toshiba SSD in the XPS 15 9500 and the likewise 256 GB BC511 in Acer's TravelMate P2 are even further behind. In everyday life, however, one accepts any disadvantages because the subjective response behavior of the SSD is nevertheless fast.

Graphics card
The integrated AMD Radeon RX Vega 6 serves as the graphics card, and the integrated GPU is one of AMD's biggest advantages over current Intel CPUs. In the 3DMark Time Spy benchmark, it achieves about 42% higher graphics performance in our test device than UHD-Graphics-620- or -630-based laptops, which are not suitable for more than high-resolution videos.
On the other hand, the RX Vega 6 is on average almost 20% faster in other laptops, which is probably due to the fact that it benefits from Dual Channel RAM in some models. Our EliteBook 855 G7 passes the Fire-Strike load test with a frame rate stability of 99.2%.

Emissions - EliteBook stays cool and quiet
Noise emissions
When idle, while surfing and during video playback, the fan is almost always turned off, allowing the laptop to operate completely silently. If the fans do need to start up, they are still very quiet at 26.4 dB(A) with a background of 25 dB(A).
Even under load they are not quite audible at only 28.7 dB(A), but in this case they are a bit more noticeable due to their high-frequency whistling. But even then they are not really loud or disturbing. Overall, the EliteBook 855 G7 is just as quiet as our comparison devices.

Temperature
When in use, the laptop stays very cool and can be used on the thighs without any concerns. The maximum temperature is 26.6 °C (~80 °F) in idle mode and rises to only 35.2 °C (~95 °F) under load. In everyday use, the EliteBook 855 G7's palm rests and keyboard always feel pleasantly cool due to the metal construction.
In the stress test, the CPU and GPU clock frequencies are initially 4 GHz and 1,500 MHz (30 watts) respectively. After a few seconds, the performance drops to around 3.6 GHz or 1,300 MHz (25 watts). Then the CPU and GPU slowly level off at 3.5 to 3.6 GHz or 1,250 MHz (25 watts). The waste heat of the six-core CPU seems to be dissipated well, since the CPU clock is still at a good 3.5 GHz even at the end of the stress test. The core temperatures of CPU and GPU are at maximum 79 and 74 °C (~174 and 165 °F) respectively.
(+) The maximum temperature on the upper side is 35.2 °C / 95 F, compared to the average of 34.2 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(+) The bottom heats up to a maximum of 34 °C / 93 F, compared to the average of 36.7 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 25.8 °C / 78 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 27.5 °C / 81.5 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.7 °C / 81.9 F (+0.2 °C / 0.4 F).
Speakers
The Bang & Olufsen speakers installed above the keyboard actually produce a relatively clear sound, but the overall impression still suffers from the rather thin bass. Thus, the speakers are very well suited for VoIP calls, but for more than just filling small rooms, the relatively low maximum volume is not sufficient. External audio devices can be connected via the 3.5 mm jack or via Bluetooth.

Energy consumption
When idle on the desktop, between 3.6 and 9.5 watts are consumed, depending on brightness level and performance profile. In the stress test, the original consumption of 36.4 watts drops after about one minute and finally stabilizes at 34.4 watts. When running Prime95, the EliteBook 855 G7 reaches a temporary consumption peak of 40 watts, which means that the included 65 W power supply is more than adequate.

Battery life
The battery capacity is 56 Wh, which is relatively high for an office laptop. This is also reflected in the very high WLAN runtime (150 cd/m²) of 12:13 h, the highest in the field of comparison. Under load, however, the EliteBook 855 with a runtime of 1:41 h is rather in the midfield. The video runtime in our standardized test (Big Buck Bunny h.264, 150 cd/m², WLAN & Bluetooth deactivated) is 13:23 h.

Pros
Cons
Conclusion - EliteBook with potential
The HP EliteBook 855 G7 shines with a stylish look and solid workmanship. HP has obviously placed great value on the design and the weight is also a good deal lower than most of its competitors. As long as you limit yourself to moderately demanding tasks, the performance of the laptop is far above what you actually need. The powerful AMD CPU does its job fast, even offers a bit more graphics performance than its Intel counterparts, and maintains a constant performance level even under load.
The display gets by without PWM, but does not really stand out from the crowd. The other display options, which can offer a brightness of up to 1,000 cd/m² for example, are interesting.
The stylish business notebook from HP offers interesting configuration options, but is not necessarily suitable for every purpose.
There is potential for improvement, for example, in the keyboard, which is only average despite its high price, and the unnecessarily laborious maintenance. The fact that an SD card reader is completely missing probably disqualifies the EliteBook 855 G7 for one or the other potential buyer. Since 8 GB RAM can quickly become scarce in many cases, one should consider before buying whether an added value can be gained from a configuration with 16 GB RAM.
All in all, the EliteBook 855 G7 is a tempting offer for all those who travel a lot, which is made even more attractive by the functional features of certain configurations.
