HP EliteBook 755 G5 (Ryzen 7 2700U, Vega 10) Laptop Review
With the EliteBook 755 G5, HP continues its strategy of offering attractive business notebooks with AMD technology and many security features. With the latest generation, the design of the 700 series has been adjusted and now corresponds to that of the HP EliteBook 850 G5. Our test unit offers an AMD Ryzen 7-2700U CPU with an integrated Radeon RX Vega 10 graphics card, 8 GB of working memory, and a 500 GB SSD.
In addition to the HP EliteBook 745 G5, the competitors of the EliteBook 755 G5 also include the Lenovo ThinkPad T480s, Dell's Latitude 5490, and of course its predecessor, the EliteBook 755 G4. Due to the lack of high-quality business devices with an AMD processor, most of the competing devices are equipped with Intel CPUs. So while a comparison is possible, we cannot let it face-off against other AMD notebooks.
Case - The EliteBook 755 G5 with a metal case
The case of the HP EliteBook 755 G5 shares an identical build with that of the HP EliteBook 850 G5. We therefore direct you to that review, pointing out that not only the design, but also the measurements and connection equipment are exactly identical. Interested buyers should also keep in mind that while there is a Thunderbolt and a docking port, HP does not include any SD or microSD card reader.
Communication
Thanks to the ac standard and support of the 5 GHz band, the HP EliteBook 755 G5 offers users fast WLAN, and it also has a SIM card slot for mobile communication. In our measurements, the EliteBook 755 G5 is able to shine with good data transfer rates, but slightly falls behind the competitors.
We notice in the comparison with the predecessor and the competing models that our test unit is primarily weak in the data reception and must be content with the last place of our comparison list in this discipline.
Security
As a business device, the EliteBook 755 G5 offers several security features. These include TPM 2.0, a smartcard reader, a Kensington Lock, a fingerprint sensor, and several software solutions from HP. The fingerprint sensor recognizes the stored prints very fast and offers a good alternative to the conventional password.
Accessories
The HP EliteBook 755 G5 merely includes the corresponding power supply and warranty information. However, HP offers a number of suitable generic notebook accessories on its own website.
Maintenance
While the HP EliteBook 755 G5 does not offer any maintenance covers for easy access to the RAM or storage, you can remove the bottom cover after you have loosened eight screws. This will give you access to the whole interior, and the fan can be cleaned or hardware components can be replaced.
Warranty
HP offers a warranty of 36 months to the buyers of the EliteBook G5 and also offers the ability to purchase additional service options. Please see our Guarantees, Return policies and Warranties FAQ for country-specific information.
Input Devices - A business notebook with a TrackPoint
The input devices of the EliteBook 755 G5 are also identical to those of the HP EliteBook 850 G5, so we point you to its review here.
Display - HP display with a good color space coverage
While the HP EliteBook 755 G4 predecessor still offered a TN panel with bad viewing angles, HP now offers three IPS models that differ in their color space coverage and touch function. Our test unit has a non-reflective display with a resolution of 1920x1080 pixels and a brightness value slightly above 400 cd/m². This value is higher than that of comparable devices, making the EliteBook G5 also suitable for work outdoors.

The display backlight flickers at 21000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 21000 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8508 (minimum: 5 - maximum: 343500) Hz was measured. | |||
Outdoors, the HP EliteBook 755 G5 can be used in shady places. However, with increasing brightness outside the shade, it becomes increasingly difficult to read the display contents. While the matte display prevents reflections of the surrounding objects, the brightness is still insufficient to outshine the surrounding light outdoors. Our test image also shows screen bleeding, although this only becomes clearly visible due to the long exposure period.
The IPS panel in the HP EliteBook 755 G5 has very stable viewing angles. The display contents can be read from almost any position, making the HP notebook also suitable for use in unusual positions.
Performance - A business laptop with a Ryzen CPU
HP has equipped our test unit with AMD's Ryzen 7-2700U CPU, an integrated Radeon RX Vega 10, 8 GB of working memory, and a 500 GB SSD. As alternative equipment options, you can also get the EliteBook 755 G5 with the Ryzen 5 2500U or the Ryzen 3 2300 U. Various SSD configurations from 128 to 512 GB are also available, and the RAM can be increased up to 32 GB. This makes the EliteBook 755 G5 suited for most office tasks and also capable of taking on more demanding tasks.
Processor
AMD's Ryzen 7 2700 U is a quad-core processor with clock speeds between 2200 and 3800 MHz. The TDP can be varied between 12 and 25 watts and lies nominally at 15 watts. However, the actual available performance depends primarily on the cooling system.
While our test unit is able to use its full performance in the beginning of the Cinebench endurance test, the results quickly drop by about 18%. In the single test, the HP EliteBook 755 G5 achieves almost exactly the average value of the multi-core performance that we determined using other devices with the Ryzen 7 2700U. The EliteBook 745 shows that more performance would have been possible in principle, particularly since the case of the 755 G5 is larger and could offer more space for the cooling.
You can find out in our CPU benchmark page how AMD's Ryzen 7 2700U fares in comparison with other CPUs.
System Performance
In the tests of the system performance, the EliteBook 755 G5 places barely below the average of comparable devices with the AMD Ryzen 7 2700U. Compared to the notebooks from other manufacturers and Intel CPUs, our test unit is also able to offer a decent system performance.

Graphics Card
A Radeon RX Vega 10 handles the display of contents in the HP EliteBook 755 G5. This integrated graphics card offers a clock speed of up to 1300 MHz and benefits from fast dual-channel RAM. Since our test unit only offers built-in single-channel RAM, you could definitely achieve better 3D benchmark values with another working memory solution.
While the Vega 10 does not achieve its highest possible performance in our benchmark tests, in the EliteBook 755 G5 it can place itself significantly ahead of devices with Intel's UHD Graphics 620.
You can find out on our GPU benchmark page what performance other GPUs can offer compared to AMD's RX Vega 10.

Emissions - The HP EliteBook 755 G5 has a quiet fan
Noise Emissions
During idle operation and easy load, the HP EliteBook 755 G5 is almost silent. When the load on the system increases, the fans rev up and become audible after some time. However, they are not loud even then, making the EliteBook G5 also suitable for use in quiet surroundings.

Temperature
During idle operation, we measure moderate surface temperatures of around 30 °C (~86 °F) on the EliteBook 755 G5. With increasing load, the HP-Notebook warms up, reaching the 40 °C mark (104 °F) at the fan vent on the right side. In our stress test, we put extreme loads on the system, causing the core temperatures to rise up to 70 °C (158 °F) and the clock speed to drop significantly down to a minimum of about 1400 MHz.
Even though the EliteBook 755 G5 throttled the performance by almost 20% after a short time in the CinebenchR15 endurance test, there should not be any significant performance limitations due to too high temperatures, since a load such as in our stress test scenario is almost impossible in everyday life.
(+) The maximum temperature on the upper side is 39.8 °C / 104 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(±) The bottom heats up to a maximum of 40.2 °C / 104 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 28.7 °C / 84 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 31 °C / 87.8 F and are therefore cool to the touch.
(-) The average temperature of the palmrest area of similar devices was 27.6 °C / 81.7 F (-3.4 °C / -6.1 F).
Speaker
HP is cooperating with the Danish sound experts Bang and Olufsen for an optimized sound quality of the EliteBooks. In our 755 G5 test unit, this optimization results in a relatively balanced sound where only the lower tones are underrepresented. The speakers are quite suitable for prolonged enjoyment of audio contents. Even though the maximum volume is relatively low, the sound reproduction is sufficiently loud to stand up against minor environment noises.
A combined audio port is available to connect external speakers or a headset.

Verdict - Design and performance in one device
Pros
Cons
HP offers a cultivated generation update to the buyers of the EliteBook 755 G5. The performance of the AMD Ryzen 7-2700U CPU is good, but could have been even better with an optimized cooling. The removable bottom cover offers the users access to the insides enabling them to perform maintenance tasks. The good color space coverage is slightly diminished by the high black value and the low contrast.
The HP EliteBook 755 G5 is an appealing business notebook with sufficient performance also for more demanding tasks and a battery life that lasts for a whole working day.
The users receive a device that is presentable with its attractive design and offers sufficient battery life for one working day. The fact that the power consumption is higher than in other devices does not have any grave consequences, and aside from that, there are hardly any reasons that speak against a purchase of the HP EliteBook 755 G5.
