Overview HP 255 notebook G7, G6 455R ProBook and EliteBook 735 G6 based on mobile AMD Ryzen

In 2019 every housewife has heard of the processor Ryzen. Indeed, the chips based on the architecture of Zen, was very successful. Series desktop processors Ryzen 3000 is well suited for the creation of a system unit with an emphasis in entertainment and to build powerful workstations. We see that, when it comes to platforms and sTRX4 AM4, AMD almost in all categories is observed the advantage of “red” platform is more functional and look better in the slice of “price — productivity”. At the same time, which is not surprising, AMD increases its influence in the market of mobile computers. Today you will meet with three interesting laptops of HP — the largest representative of the corporate segment of computing.

Basic characteristics of test model 735 HP EliteBook G6

I note that the models 455R G6 ProBook and EliteBook 735 G6 is, so to speak, relatives. So, in selling you will encounter a series 445R G6 ProBook and EliteBook 745 G6. The difference in one digit in the name indicates that it is the laptops with 14 inch screens. The rest of these series are very similar.

As you may have noticed in HP ProBook and EliteBook 455R G6 G6 735 are running different versions Ryzen 5 3500U. In particular, the client can get a laptop with the PRO version of the processor. These processors support technologies such as GuardMI and AMD DASH 1.2.

GuardMI is a built-in security features that help customers to avoid, as it can now be called cybercrime. So, the function produces a Guard AMD Memory encryption and decryption in real time the total memory. As a result, trespassers no chance of success, associated with attacks by cold reboot. By the way, the solutions supporting Intel vPro technology no equivalent alternatives AMD Memory Guard. Feature AMD Secure Boot provides a secure boot and to prevent threats to mission-critical software. Finally, the chips Ryzen support such security technologies to Windows 10 as Device Guard Guard Credential, the TPM 2.0 and VBS.

Technology DASH (Desktop and mobile Architecture for System Hardware architecture system hardware for fixed and mobile systems) significantly simplifies the management computer. Technology is continuously improving, because we are dealing with an open standard, which is constantly modernizarea and develops. Removed DASH allows you to manage desktop and mobile systems. Such systems help administrators to perform tasks, regardless of the computer’s power state or operating system. For example, it is possible to safe starting the system remotely, even if it is currently turned off. The administrator can obtain all the necessary information about the health of the system components, even if the operating system is unavailable.

Among the three models of HP laptops tested in our test laboratory, only on HP EliteBook 735 G6 installed chip Ryzen PRO-series. Other laptops uses the “simple” version of an AMD CPU. However, HP offers its customers a number of interesting proprietary technologies including security.

For example, models 255 HP support G7 firmware Trusted Platform module (TPM), which creates the hardware encryption keys to protect data, email and user credentials. Series HP ProBook 455R G6 is equipped with HP BIOSphere Gen4, operating in automatic mode at the level of the firmware — it enhances computer performance and reduces the downtime, as well as automatically updates the firmware and verifies the safety of the device. Finally, the series notebooks HP EliteBook 735 G6 supports HP Sure View Gen3. It can help to reduce the illumination of the screen, making it dark and unreadable to people nearby and allows you to hide screen information from prying eyes. And then there are technologies HP Sure Start and HP Sure Click, which also help to protect the entire computer from the BIOS to the browser.

All models used the professional version of Windows 10.

HP 255 G7

Case 255 HP G7 is made of practical plastic matte dark gray. The laptop is small, its thickness is only 23 mm, the device weighs less than two pounds, so this 15-inch model is quite convenient to carry — at least to the man. Consider that the laptop power supply weighs only 200 g


Cover 255 HP G7 reveals about 135 degrees. Open it with one hand not be too easy it turns out this laptop, if we’re talking about 15-inch models. However, by the hinges, no complaints — they are clearly positioning the screen, will last a long time.


To us in edition has arrived model, which uses a TN panel with Full HD resolution is AUO B156HTN03.8 (AUO38ED). Type of matrix is easy to determine, since the screen has small viewing angles in both planes. In General, the laptop uses a good panel, we are talking about cheap series laptops. So, the contrast from AUO B156HTN03.8 is small — only 325:1. The maximum luminosity of the white is 224 CD/m2 and the minimum was 15 CD/m2. However, the average error DeltaE for grayscale is 6.2 with a maximum value of 9.7. But the average in the test ColorChecker24 was 6 with a maximum deviation of 10.46. The manufacturer claims that the color gamut matrix corresponds to 67% of the sRGB standard.

HP 255 G7 is today considered the only model that comes with an optical drive. Here, in the right pane, you will find USB 2.0 A-type, and card reader supporting memory devices SD, SDHC and SDXC. Right the laptop has a RJ-45, HDMI out, two USB 3.1 Gen1 A-type and 3.5 mm mini Jack for headphones and microphone.

In 255 HP G7 uses a full-size keyboard with numeric keypad. Built-in backlight no, but in the daytime I use the keyboard is very convenient because it has a large Shift, Enter, Tab and Backspace. A number of F1-F12 by default works in combination with the Fn button, while the priority is given to their multimedia functions. This feature is inherent in all the discussed in this article laptops.

The laptop uses a webcam with a resolution of 720p and a frequency of 30 Hz. It is enough for Skype calls. I should add that the unlock of the operating system are possible including using face authentication (Windows Hello), and management of various functions using voice commands (Cortana virtual assistant).

Disassemble HP 255 G7 is not easy. To remove the bottom, you need to first peel off the rubber feet and Unscrew a few hidden screws. To do this, we did not. In the test version used 255 HP G7 dual core processor Ryzen 3 2200U, 8 GB of RAM DDR4-2400 and an SSD Samsung MZNLN256HAJQ-000H1 256 GB.

For the removal of heat from Ryzen 3 2200U meets simple cooling system consisting of a single copper heat pipes and one fan. In Adobe Premier Pro 2019, which, as we know, very strongly loads the subsystem “processor — memory”, frequency 2-core chip remained stable at 2.5 GHz, although at a lower load it can reach 3.4 GHz. In this case the maximum temperature reached 72.8 degree Celsius, and the noise level measured from a distance of 30 cm, amounted to 40.8 dBA. Well, we can see that the cooler 255 HP G7 works effectively, and not so loud.

Disassemble the laptop makes sense over time because the test model is well upgrade. So, 8 GB of RAM assembled in a single module form factor SO-DIMM slots, but motherboard HP 255 G7 is equipped with another connector. Drive Samsung MZNLN256HAJQ-000H1 refers to a series of PM871b connected to the M. 2 socket, though, and works with interface SATA 6 GB/s through the SATA connector to the laptop can connect another drive form factor of 2.5’. Performance Samsung MZNLN256HAJQ-000H1 shown in the screenshot above.

HP ProBook 455R G6

Case HP ProBook 455R G6 partially made of metal with a smooth silver coating. The manufacturer claims that the panel with the keyboard and the screen cover of the laptop is made of aluminum. The bottom of the laptop plastic. The build quality of the device we have no complaints. In addition, the laptop has a military certificate of quality MIL-STD-810G.


Cover HP ProBook 455R G6 reveals to 135 degrees. The hinges of the laptop is clearly positioning the screen in any position. The door itself is no problem to open with one hand. The thickness of the laptop is less than two centimeters, and its weight is only 2 kg, which, as we have noted, is a great feature for models with 15.6-inch screens.

In selling you will encounter a lot of versions of this laptop. To our test got the model equipped with IPS-matrix BOE07FF with Full HD resolution and anti-glare. However, in the market you can find HP ProBook 455R G6 with screens with a resolution of 1366 × 768 pixels.


The laptop display has a maximum brightness of 227 CD/m2. Minimum luminosity white is 12 CD/m2. The contrast is not very high for an IPS-matrix — 809:1.

In General, the calibration of the screen held at a good level. The laptop uses matrix color gamut which is 67 % of the sRGB standard. The average error on the gray scale made up 4.17 (12,06), and the deviation in the measurement of 24 color patterns — 4,87 (8,64). Gamma equals 2.05, and is slightly below the reference parameter to 2.2. Color temperature tends to the recommended 6500 K. well, it is obvious that the quality of the matrix BOE07FF is quite enough for office work and beyond.

Among the interfaces on the left side of the laptop there’s only USB 2.0 connector A-type food and a card reader that supports flash media of SD, SDHC and SDXC. A large part of the end is a grate cooler. On the right HP ProBook 455R G6 has a USB 3.1 Gen1 Type-C, combined with a DisplayPort (it can also charge a laptop), RJ-45, HDMI-out and two USB 3.1 Gen1, but A-type. As you can see, with the functionality of the test sample are all right.

When looking at the panel with the keyboard immediately draws attention to the fingerprint sensor, located to the right. The rest of the button layout of HP ProBook 455R G6 is very similar to the layout of the keyboard just studied 255 HP G7. Except that this model has “two-storey” Enter, the larger the arrow buttons “up” and “down”, but the smaller left Shift key. And keyboard HP ProBook 455R G6 has a three-tier white backlighting.

The laptop is very simple understand. Motherboard for HP ProBook 455R G6 has two SO-DIMM slots — in the case of our test sample it has two memory module DDR4-2400 total capacity of 16 GB. And there are SD9SN8W SSD SanDisk 128G-1006 capacity of 128 GB and a hard drive Western Digital WDC WD5000LPLX-60ZNTT2 capacity of 500 GB. With the performance of these storage devices, you will learn, after examining the attached screenshots.

The CPU Ryzen 5 3500U is cooled by the cooler, consisting of two teplorulon and one tangential fan type. Under serious load HP ProBook 455R G6 is not very loud — measuring device with a distance of 30 cm fixed to 41.6 dBA at peak. Processing 4K video project in Adobe Premier Pro 2019 took us a total of 2282 S. the frequency of the chip periodically fell to 1.8 GHz — this is due to exceeding the power limit, but the average frequency 4-core was 2.3 GHz. The processor is not overheating: the maximum temperature of the chip was 92.3 degrees Celsius but the average temperature was the mark of 79.6 degrees Celsius. Well, cooler HP ProBook 455R G6 the job efficiently.

HP EliteBook 735 G6

I must admit that the HP EliteBook 735 G6 is very similar to the just reviewed the HP ProBook 455R G6. Once this model is fully made of aluminum.


Before us is the most compact laptop. The thickness of the HP EliteBook 735 G6 is only 18 mm, and its weight does not exceed 1,5 kg. This laptop is convenient to take with you.

Laptop cover reveals approximately 150 degrees, it can be easily lifted with one hand. All versions of HP EliteBook 735 G6 used IPS-matrix with Full HD resolution. In the sale there is also a version that support HP Sure View, which we have already described. And, you can buy upgrades HP EliteBook 735 G6 touch screen.


In the test sample tested in our lab used IPS-matrix AUO AUO5D2D equipped with anti-reflective coating. It is characterized by excellent image quality, but because the HP EliteBook 735 G6 can advise including the professionals working with photos and videos.

See for yourself, the maximum brightness of the screen is 352 CD/m2 (minimum — 17 CD/m2). We have measured gamma was 2.27, and the contrast — 1628:1. Yes, HP EliteBook 735 G6 is perfect for watching movies. The picture is bright, clear and very deep. The color temperature of the screen is slightly above the nominal value of 6500 K. because Of this, the average deviation in gray scale of 1.47 is at the maximum value of 2.12 is a very very good result. The average error in the test ColorChecker 24 was of 2.25 and a maximum of 4.75. Have AUO5D2D — perfect viewing angles and are not detected PWM.

The laptop is equipped with the following connectors: two USB 3.1 Gen1 A-type, one USB 3.1 Gen2 type-C (supports charging function and connection DisplayPort cables), HDMI output, Ethernet port, slot for smart card reader, a 3.5 mm mini-Jack socket for SIM-card slot to connect a docking station. As you can see, with the functionality of HP EliteBook 735 G6 everything is in order. We can connect to your laptop, for example, just two monitors. And if you want to increase the set of connectors in the computer, you can use a docking station HP Thunderbolt G2, for example.

Keyboard HP EliteBook 735 G6 white has two-level backlight. The rest of the layout is very similar to what we saw in HP 255 G7, — only missing the digital block. And all three notebooks support the HP noise reduction Noise Cancellation, which suppresses ambient noise, including the sounds of the keyboard.

However, HP EliteBook 735 G6 is equipped with dual pointing devices: touchpad with three buttons and a mini joystick. The touch panel device is convenient enough to work. The coating at first glance it seems the same as on the case, but it turns out more smooth and more pleasant to the touch.

The web camera has a shutter — useful for those who believe that Big Brother is watching them.

The laptop is quite simply understands. Which is nice, HP EliteBook 735 G6 uses a removable memory, and not soldered. In this case we have two modules DDR4-2400 total capacity of 16 GB.

Unlike the first two laptops of this model installed quick NVMe drive- the results of its testing are given below. The ability to install 2.5-inch hard drive from HP EliteBook 735 G6 no.

For cooling Ryzen 5 PRO 3500U meets cooler, consisting of a single copper heat pipes and one fan. In Adobe Premier Pro 2019, which we are seriously loaded laptop, the frequency of the 4-core is periodically dropped to 1.76 GHz. As in the case with HP ProBook 455R G6, this is due to the limitation of the processor at TDP. The cooling system does its job: the maximum temperature of the CPU was only 81.4 per degree Celsius, and the maximum noise level is 41.3 dBA.

Test results

Performance measurement of CPU and memory was undertaken using the following software:

  • Corona 1.3. To test the speed of rendering using the same rendering. To measure the speed of constructing a standard BTR scenes used for measuring performance.
  • Blender 2.79. Determination of the speed of the final rendering in one of the most popular free package for creating three-dimensional graphics. Measured the duration of the construction of the final model from Blender Cycles Benchmark rev4.
  • x265 HD Benchmark. Test the speed of transcoding video in the perspective format: H. 265/HEVC.
  • CINEBENCH R15. Measurement of performance photorealistic three-dimensional rendering and animation package CINEMA 4D-test the CPU.

The test display was carried out using the colorimeter X-Rite i1Display Pro and HCFR application.

The time of the laptop battery was tested in two modes. The first version of the load — surfing the web — involves alternately opening and closing tabs sites 3DNews.ru, Computeruniverse.ru and Unsplash.com with an interval of 30 seconds. For this test, use the browser Google Chrome the latest version. In the second mode in the embedded player Windows 10 plays FHD videos with the extension .mkv to activate the snooze function. In all cases, exhibited the same display brightness 180 CD/m2, switched mode power supply “battery saver mode” and turns off the backlight of the keyboard, if any. In the case of video playback laptops are in the “in plane”.

At the beginning of the article, we noted that the desktop processors Ryzen, published this year, sorgudan compete with Intel. Well, the following test results show that in the mobile market AMD solutions look at least not worse, but often better.

  Intel Core i7-8550U [HP Spectre 13-af008ur] AMD Ryzen 3 2200U [G7 HP 255] AMD Ryzen 5 3500U [HP ProBook 455R G6] AMD Ryzen 5 PRO 3500U [735 HP EliteBook G6]
Corona 1.3, with (less — better) 450 867 403 470
Blender 2.79, with (less — better) 367 633 308 358
Adobe Premier Pro 2019 (less — better) 2576 4349 2282 2315
x265 HD Benchmark, FPS (higher is better) 9,7 5,79 11.1 V 10,4
CINEBENCH R15, scores (more is better) 498 278 586 506

Of course, we must note that the performance of the computer modern programs that use multiple threads, depends not only from a bunch of “processor — memory”. Important here, for example, and SSD. Here in HP EliteBook 735 G6 installed fast SSD with PCI Express interface — and he is a great helper in the tasks associated with active reading and writing data.

In General, the best results naturally showed HP ProBook 455R G6. Its increased size allowed us to use a more impressive cooler. Consequently, the chip Ryzen 5 3500U operates at higher clock frequencies than 3500U Ryzen 5 PRO, installed into HP EliteBook 735 G6.

The performance of the HP ProBook 455R


The performance of the HP EliteBook 735

It is obvious that considered in this article, laptops are unlikely to be used for games. In these models, the graph plays the role of the assistant CPU, because it is used quite often not only in games. We see that the integrated Vega graphics can be significantly faster integrated GPU from Intel. In the case of HP ProBook 455R G6 G6 HP EliteBook 735 we are talking about more than double the advantage.

However, I want to buy some “simple” (in those for which schedule is not important) projects will succeed. Do not take into account applications with high system requirements — it is obvious that they built in CPU graphics is unlikely to manifest itself in a positive way. However, the level of Dota 2 and WoT on the minimum graphics quality settings to get playable frame rate at a resolution of 1920 × 1080 pixels I was able.

We have checked the quality and performance of the main components of the test laptops. We have to find out another important feature of any mobile computer — autonomy.

The table below demonstrates that all three laptops have good endurance and, in General, lies strictly in what capacity battery is used in a particular model. Here, which is not surprising, best of all showed the system HP EliteBook 735 G6 — in preview video, she worked for almost 10 hours! Great result, admittedly, because we’ve tested laptops with high screen brightness — 180 CD/m2.

In the example just considered laptops, I think you have seen that HP is able to meet the needs of any user who need a laptop to perform various office tasks, and, if necessary, and entertainment. A large series of mobile computers based on processors AMD has multitasking, decent performance and features upgrade. Laptops are considered functional and effective. In the corporate segment, security is very important, and solutions from both AMD and HP perform well on the field. Finally, tested the laptops look good against the competition in terms of price.
