HP EliteBook 755 G5 (Ryzen 7 2700U, Vega 10) Laptop Review

Mike Wobker, Felicitas Krohn (translated by Mark Riege), 07/21/2018

AMD for Business. HP's EliteBooks offer an attractive design, AMD technology, and many security features. However, these business notebooks frequently stood out with a high power consumption, their low display quality, and a mediocre battery life. We evaluate in our review of the HP EliteBook 755 G5 whether something has changed with this newest generation.

HP EliteBook 755 G5

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.

* ... smaller is better

Our measurements of the EliteBook 755 G5 display attest it with an elevated black value of 0.62 and a contrast ratio of 735:1. While this means that the display is better than in the EliteBook 755 G4 predecessor, comparable devices offer a better display. However, our test unit can surpass the competitors in terms of the color space coverage, offering 90% of the available sRGB color space and 59% of the AdobeRGB color space.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
32 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 82 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
39 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 19 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 21000 Hz ≤ 90 % brightness setting

The display backlight flickers at 21000 Hz (Likely 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 8929 (minimum: 43 - maximum: 142900) 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.

Cinebench R15 CPU Multi 64 Bit

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.

Graphics Card

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

Stress test
Stress test

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.

Speaker

Speaker characteristics
Speaker characteristics

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.

Battery Life

The EliteBook 755 G5 is able to last more than eight hours in our realistic WLAN test. This should at least cover a whole working day. Even though some of the competing devices can offer a slightly longer battery life, our test unit still clearly surpasses the average office notebook.

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.
