Price and availability


Several generations of Chromebook have followed since 2011, the majority at affordable rates, based on less powerful processors. That time is over: here in 2015, are announced first Chromebook cheap in the 5th generation Intel (Broawdell-U). The CB5 series of Acer, whose career began in 2014 in the shadow of other Chromebooks, leading the way with the model “CB5-571-32AS” with one of these processors. Write this name: it is one of the first affordable models (under 400 euros bar) with a power of 2 times, on paper, to previous generations. Until then, Chromebooks were rather small, lightweight and very powerful. Here’s the test of a Chromebook that reverses the trend.

The Acer Chromebook CB5-571-32A takes the sun

This Chromebook from Acer with a processor from the new Broawdell-U family, announced by Intel in January 2015 at CES in Las Vegas. After several generations of Celeron, he finally comes to a Core i3, 5th generation, engraved in 14 nm. It has a fan, I managed to trigger a few times, but remains extremely discreet.

A large but transportable Chromebook

Please note, the machine clearly has a size XXL: it is large, but mostly exceed each side of your knees by its width (39 centimeters), the fault of the nearly 16-inch screen, the 16/9 format. It remains however very fine, with 2.5 cm thick, which is significant, but also cumbersome, largely exceeding A4. The CB5 Acer displays 2.2 kilos on the scale. Here we are well above other Chromebook, which have accustomed us to remain discreet in this area, rarely exceeding 1.5 kilograms. In use, this weight is nevertheless content with respect to its size. These two kilos are acceptable for travel.

The plastic top of the device

The most demanding will be disappointed about finishing, that appears pretty average: white plastic, smooth inside, not breathing upscale, and looks pretty messy to use. Finishing at the side of the speaker grilles are not blameless. This is clearly not an area where we expected this model, and the miracle did not happen. Outside Honeycomb, which allows frank grip during transport and printing overall strength (hinge, touchpad …) make rather, like many other Chromebook, and despite its size, a fighter unit , which carries no bag.

The side grilles

Finally, Acer delivers a classic delivery side of connectors: a USB 3.0 port, one USB 2.0 port, an SD card reader, a micro-HDMI port and a headphone jack / microphone jack. Wireless connectivity is provided by the 802.11ac WiFi, dual band. The observed rates are excellent even in a saturated environment, a stable connection is maintained. We were able to associate a Bluetooth headset music simply and safely thanks to the onboard Bluetooth 4.0 chip.

Screen, keyboard and touchpad

Acer offers this model 32AS a screen with a WXGA resolution (1366 by 768 pixels). With its size of 15.6 inches, it will not be unanimous, especially among those who do not like to see the pixels (because we see a bit anyway …). Other console themselves by noting that it helps to preserve the autonomy and improve machine performance. Especially as the quality of the proposed display, beyond its definition, is not in question: matt, rather light, it allows use without difficulty outdoors. One could blame her side viewing angles a bit low.

Full keyboard with touchpad

Another model is available with a 15.6 inch higher quality (Full HD IPS), but it will likely pay more than 400 euros (model CB5-571-C1DZ) to acquire it. Finally, it is regrettable that this screen is not touch, even if the uses associated with this feature appear less developed on a Chromebook as a tablet.

The keyboard is very comfortable appeared: the keys are wide and thin, typing is easier. The configuration will require some time to adapt to those coming from the Windows world: it lacks for example the Delete button we find a keyboard shortcut. The lack of navigation key dedicated to music, however, is a real lack, though I imagine that there are also keyboard shortcuts. We also regret, like many Chromebook, there is no backlight.

Finally, the touch area is a joy: sensitive and configurable include sensations offered by a Mac as its reactivity that accompanies the OS.

We change the gear ratio

This Acer Chromebook version features the Intel Core i3 processor 5th generation, based on the micro-architecture Broadwell presented by Intel in 2015.

In use, there is a power beyond all Chromebook in this category: the interface remains fluid even in heavy use (dozens of tabs open), it reads easily Full HD video transferred to SSD, or even 4K from YouTube. Finally, there is a maximum reactivity with the ignition (5 seconds) and when exiting standby.

In terms of benchmarks, the figures speak

Octane 2.0: 19,000 against (less than 10 000 for the best Celeron N2830)

SunSpider 1.0.2 – 300 Ms (+ 600 for the best Celeron N2830)

PeaceKeeper: about 4000 (- 1500 for the best Celeron N2830)

Specifically, during my few weeks of testing, I have not managed to slow the beast, except to open a large Word file that hurts just as the Core i5 4th generation PC control under Windows I have. And yet, much of this slowdown could be attributed to a relative network latency …

This is indeed one of the shortcomings of previous generation Chromebook, many times observed in various tests present on the canvas, disappearing: this Chromebook Acer Announces generation products that no longer fears intensive use. This good news adds to arguments for this platform, aptly described in this article.

ChromeOS true to himself

Like all Chromebook, the Acer running course Chrome OS. During our test, these are the 44 and 45 versions of the OS that we could test. Little change in relation to the version described in Test Dell Chromebook 11 (CRM3120) in July.

First summarize just what Google offers through Chrome OS.

This is a simple OS, uncluttered, reduced to the essential: a file browser music player, photos, and videos, all three basic, integrated WiFi, Bluetooth, disc drive (USB key SD cards), and especially, of course, the Internet browser. Everything about this OS is facing the Chrome browser, which gives it a response and unprecedented ease of use.
