HP EliteBook 820 G2 Subnotebook Review

Sascha Mölck (translated by Martina Osztovits), 06/15/2015

Broadwell upgrade. The EliteBook 820 G2 is a 12.5-inch business notebook. Overall, it left a good impression and does not need to hide from the competition. However, it also is not exactly affordable with a price of just under 2000 Euros (~$2253).

For the original German review, see here.

The HP EliteBook 820 G2 is a 12.5-inch business notebook, which belongs to the upper class among business devices. Our test model is a Broadwell upgrade to the already reviewed EliteBook 820 G1. In addition, we also had the AMD-based EliteBook 725 G2 sibling under review.

The Lenovo ThinkPad X250 and the Dell Latitude E7250 are competitors. You also could consider the Apple MacBook 12 (Early 2015) a competitor, although it rather aims at consumers and emphasizes mobility even more.

Since the EliteBook 820 models we reviewed use the same design, we will not cover case, connectivity, input devices, and speakers here. Please refer to the EliteBook 820 G1 review for information about these aspects.

Display

Our test model features a matte 12.5-inch display with a native resolution of 1920x1080 pixels. Brightness (297.7 cd/m²) and contrast (909:1) are good and cannot be criticized. In future, we only want to see such values in notebooks of this price point. Unfortunately, this will probably not be the case, which HP proved with the HD display of the predecessor.

The display of the EliteBook cannot completely cover the color spaces AdobeRGB and sRGB. The coverage is about 64.9% (sRGB) and 41.6% (AdobeRGB), respectively. We already liked the colors in factory state. A DeltaE 2000 shift of 3.68 is close to the target value (DeltaE smaller than 3). In addition, the gray levels are very balanced. The display is not bluish. Calibration only brings a small improvement.

The EliteBook is equipped with an IPS display. So, you can read from the display from any position. Thanks to the matte display surface, sufficient brightness, and high contrast, outdoor use is possible.

Performance

The EliteBook 820 G2 belongs to the business notebooks with a size of 12.5-inches. The processing performance is sufficient for all usual application scenarios. In addition, the computer delivers business functionality like docking port, TPM, and LTE modem. Our test model costs just under 2000 Euros (~$2253). HP also offers other configurations. Currently, the cheapest model is priced at about 1550 Euros (~$1746). The models of the AMD-based EliteBook 725 G2 series with the same design are significantly cheaper. They start from 650 Euros (~$732).

Processor

Our test model is powered by one of the most powerful ULV processors Intel currently offers: the Core i7-5500U dual-core processor (Broadwell). The CPU works at a base clock of 2.4 GHz. With Turbo, the clock rate can increase to 2.9 GHz (two cores) or 3 GHz (one core). In mains operation and on battery, the processor clocks at 2.9 to 3 GHz (single-thread) and 2.7 to 2.8 GHz (multithread) in our CPU tests. So, the CPU falls slightly behind its potential in multithread applications.

The already reviewed EliteBook 820 G1 houses a Core i7-4600U dual-core processor (Haswell), a direct predecessor of the Core i7-5500U CPU. The single-thread performance of the two processors is virtually on par. The Broadwell processor makes up for the slightly higher maximum clock of the Haswell processor (3.3 GHz vs. 3 GHz) with improvements in the Broadwell architecture. However, the Broadwell CPU performs significantly better in multithread applications. The results are about 10% better.

System Performance

A powerful processor and a fast Solid State Drive ensure a responsive system. We did not face problems. The results of the PCMark benchmarks are very good, too. However, our comparison diagram shows that the sibling with a weaker CPU-GPU-combination performs significantly better. RAM works in dual-channel mode in the EliteBook 820 G1, which increases the graphics performance. In addition, the computer uses a lower desktop resolution than our current test device (HD vs. Full HD). If you decrease the desktop resolution of the 820 G2 to HD and add a second RAM module, it achieves similar results as the sibling.

Storage Devices

HP equipped our test model with a Solid State Drive from Samsung. The 2.5-inch model features a total capacity of 256 GB. About 200 GB is available to the user; the rest is used by the Windows installation and the recovery partition. The transfer rates of the SSD are good. The EliteBook features an additional M.2 slot, which can be used for a compatible SSD. You could incorporate an M.2 SSD and replace the 2.5-inch SSD with a conventional hard drive. This way, you could profit from the advantages of an SSD and have much storage space available at the same time.

Graphics Card

Intel's HD Graphics 5500 GPU is responsible for graphics output. The core supports DirectX 11.2 and works at up to 900 MHz. The 3DMark results are usual for this GPU.  However, the graphics performance can be further improved by adding a second RAM module (= dual-channel mode). For example, this will increase the 3DMark 2011 score by above 10% to 1168 points.

Gaming Performance

Light gaming is possible if users want to play on the EliteBook's small 12.5-inch display at all. The hardware is capable of running games in low resolution and with low to partly medium quality settings. The success rate is higher for older games or undemanding games. Current hits like Battlefield: Hardline and GTA V will never reach playable frame rates. However, it is not completely impossible to play cutting-edge titles. For example, the game Dirt Rally runs smoothly. Again, adding a second RAM module (= dual-channel mode) will increase the frame rate. We tried it. For example, the frame rate increases by 34% to 85.7 fps in Dirt Rally.

Emissions & Energy

System Noise

While idle, the fan of the EliteBook usually stands still and the computer works silently. Certainly, it is necessary that the fan runs under load. However, it only works at moderate speed. During the stress test, we measured a noise level of 35.1 dB - a good value. Unfortunately, the fan also produces other noises: As soon as it rotates, it generates an annoying buzzing noise. Such issues must not occur in a device that costs just under 2000 Euros (~$2253).

Temperature

The EliteBook during the stress test
The EliteBook during the stress test

The EliteBook behaves the same way in our stress test in mains operation and on battery. During the first minute, the processor works at 2.5 GHz and the graphics core at 950 MHz. Afterwards, the clock rates are reduced to 1.4 to 1.5 GHz (CPU) and 750 to 800 MHz (GPU) and remain at these levels. Despite a powerful CPU in a compact device, the computer only gets relatively moderately warmer. In several measurement segments, the 40 °C level is exceeded.

Power Consumption

While idle, the EliteBook is very frugal. We measured a maximum power consumption of 6.5 Watt. During the stress test the energy demand increases up to 46.3 Watt. This is a normal value for the used hardware platform. So, the included 45-Watt power adapter is a little small. However, the power consumption is only that high for a minute, since the CPU and GPU clocks fall afterwards and the energy demand decreases to 31.4 Watt.

Battery Life

The EliteBook achieves a battery life of 15:21 h while idle. The Lenovo ThinkPad X250 (12:59 h) shuts down earlier. We test the idle scenario with the Battery Eater Reader's test: The display is set to minimum brightness, the energy module is active and the radio modules are off. Under load, the EliteBook shuts down after 1:37 h. The ThinkPad (1:32 h) is on par. The load runtime is recorded with the Battery Eater Classic test with maximum display brightness, maximum performance profile and enabled radio modules.

The HP notebook finishes our realistic Wi-Fi test in 5:38 h. The ThinkPad X250 (4:58 h) shuts down earlier. This test automatically opens websites in 40-second intervals. The profile "balanced" is active and the display brightness is about 150 cd/m². We test the runtime during video playback by playing the short film Big Buck Bunny (H.264-coding, 1920x1080 pixels) in a loop. The radio modules are disabled and the display brightness is set to about 150 cd/m². The 820 G2 lasts 4:53 h. This time, the ThinkPad (5:42 h) performs better.

The battery life is not impressive, yet it is acceptable. The 820 G2 can only outperform its Haswell sibling while idle. We think that this is due to the higher resolution of the 820 G2's display.

Verdict

The HP EliteBook 820 G2. Test model courtesy of HP Germany.

The HP EliteBook 820 G2 is a Broadwell upgrade of the 820 G1. Only the innards are different while the outside remained the same. The new CPU-GPU combination ensures a slight processing performance gain. In addition, there is a high-end case, the sophisticated maintenance and the good input devices. The device does not get too hot and can work silently. Unfortunately, the fan generates annoying side noises as soon as it is on. An LTE modem makes mobile access to networks possible. We also liked the bright, contrast-rich IPS display. Overall, the verdict on the Haswell predecessor applies here, too:

It comprehensively meets the requirements placed on a portable, professional office device.
