Acer TravelMate P658-G2 (7500U, 940MX, FHD) Laptop Review

Sascha Mölck (translated by Martin Jungowski), 05/16/2017

A fair deal. With its latest TravelMate P658-G2 top model, Acer is certainly bringing out the big guns: SSD/HDD combo, LTE modem, 16 GB of RAM. All that comes in addition to low operating noise, decent battery life, and a three-year warranty.

Acer’s TravelMate P658-G2-MG-7327 is a high-quality 15.6-inch business notebook, and it is certainly not a stranger to us: the Skylake-based Acer TravelMate P658-M-537B was in our test lab less than a year ago. The latest model is equipped with Intel’s latest Kaby Lake CPUs, and competes against the likes of the HP EliteBook 850 G4 or the Lenovo ThinkPad T570.

Given that both TravelMate models are identical in construction, we will not be addressing the case, the connectivity, the input devices, and the speakers in this article. Instead, we would like to refer you to our TravelMate P658-M-537B review for these topics.

Display

Subpixel matrix

The matte 15.6-inch display runs at a native FHD resolution of 1920x1080 pixels. Contrast levels are okay (963:1). While brightness is decent (275.9 nits) we do expect a notebook in this price range to offer at least 300 nits. Furthermore, brightness distribution is very uneven.

Unfortunately, we have noticed a 21.000 Hz PWM flickering at brightness levels of 90% and below. However, due to the high frequency we do not expect it to cause any headaches or sore eyes even for sensitive users.

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 Hz90 % 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: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6272 (minimum: 43 - maximum: 142900) Hz was measured.

Color accuracy is very good out of the box, and our initial measurement revealed a DeltaE 2000 value of 4.07 (a value of less than 3 is what manufacturers should be aiming for). We did not detect a blue tint, and we were able to improve color accuracy somewhat through calibration: DeltaE was lowered to 2.21 and thus well within its reference point. Furthermore, gray scales were improved and much more balanced.

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
28 ms ... rise ↗ and fall ↘ combined↗ 17 ms rise
↘ 11 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 58 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.7 ms).
       Response Time 50% Grey to 80% Grey
38 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 18 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. » 34 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (42.8 ms).

The TravelMate is equipped with an IPS panel with very good viewing angles. Thus, readability is good from all angles, perspectives, and positions. The notebook can even be used outdoors if it is not too bright.

Performance

Acer’s TravelMate P658-G2-MG-7327 is a high-quality 15.6-inch business notebook. Intel’s Kaby Lake processors offer ample performance for all current business requirements. The notebook is equipped with several features common for business notebooks, such as a docking port and a TPM chip. In addition, our review unit was also equipped with an LTE modem. The top model, which we have tested, currently sells for around 1900 Euros (~$2100) in Europe and is not yet listed in the United States. Other models are available as well, with the cheapest one equipped with a Core i3-6100U and an HD display selling for around 550 Euros ($600) in Europe.

Processor

Our review unit is equipped with Intel’s energy-efficient ULV-series Core i7-7500U Kaby Lake dual-core processor. It offers adequate performance for all current requirements, runs at a base frequency of 2.7 GHz, and turbo boosts up to 3.5 GHz on both cores. Turbo boost applies in both battery and when plugged in.

In order to determine whether or not the device is capable of running at its turbo boost frequency for prolonged periods of time we ran Cinebench R15’s multi-thread test for 30 minutes in a loop. The TravelMate’s results were very consistent, and we were unable to detect any drops in performance.

System Performance

A powerful processor and a fast SSD are the most important ingredients for a brisk and speedy overall system performance. Our impressions are supported by the very good PC Mark results. The notebook’s overall system performance is significantly higher than necessary for office and internet/browsing requirements. Another increase in performance on our side was impossible since Acer has already maxed the device out to its full capabilities.

Graphics Card

In addition to Intel’s HD Graphics 620, the notebook is also equipped with a dedicated mid-range Nvidia GeForce 940MX GPU. It supports DirectX 12, clocks up to 1189 MHz, and has 2 GB of DDR3 VRAM at its disposal. Thus, the notebook performed as expected in our 3DMark benchmarks. Lenovo's ThinkPad T570, which features the same GPU, performed slightly better thanks to its faster GDDR5 VRAM.

Gaming Performance

Quite a few games will perform acceptably, thanks to the GeForce GPU, albeit you have to limit yourself to a resolution of no more than 1366x768 (HD) and low to medium details. Modest games, such as “Dota 2 Reborn” or “FIFA 17”, will run well on higher details and resolutions. Current and more demanding games, such as “Prey”, will only run at acceptable frame rates with significantly reduced details and at lower resolutions. Yet other games, such as “Mafia 3”, will not perform well enough to be considered playable at all.

Emissions & Energy

System Noise

When idle, the TravelMate’s fan is off and the device is therefore completely silent. Except for the rotating 2.5-inch hard drive of course. The fans quickly ramp up under load, and reach an acceptable maximum level of 38 dB(A) under heavy load.

Unfortunately, the device suffers from occasional coil whining, for example, when transferring large amounts of data (as is quite common during our SSD tests).

Temperature

TravelMate during our stress test
TravelMate during our stress test

The laptop performed differently in our stress test (Prime95 and FurMark simultaneously for at least one hour) depending on whether it was plugged in or running on battery. The GPU was always running at its full 1189 MHz clock rate. The CPU, however, ran between 2.4 and 2.7 GHz with the laptop plugged in, and between 1.7 and 1.9 GHz when running on battery.

When plugged in, the device heated up significantly during our stress test. However, this should not happen during everyday use and so it did not cause us any concern. After all, our stress test is a rather uncommon extreme load scenario.

Frequency comparison (checkboxes selectable/deselectable!)

Power Consumption

When idle, the laptop’s power consumption was at a rather high 11.3 W. It reached 62 W during our stress test, which means that the 65 W charger is barely powerful enough to keep the laptop running. In fact, the battery even discharged from 100% to 91% during our one hour long stress test. Again, this should not occur during everyday use since extreme load scenarios such as these are very uncommon. Still: Acer should have included a 90 W charger with the device instead of the 65 W charger that can be found in the box.

Battery Life

Our real-life Wi-Fi test simulates the load that occurs while browsing the web. The energy profile is set to “Balanced”, all automatic power save features are disabled, and display brightness is set to 150 nits. With these settings, the TravelMate ran out of juice only after 8:26 hours, and was thus on par with its own predecessor.

Verdict

The TravelMate P658-G2-MG is a second generation P658-series model, and compared to the first generation it has only been improved on the inside. Thus, the second generation features the exact same sturdy, well-made case and the decent backlit keyboard. The ports have also remained unchanged.

With the second generation TravelMate P658 Acer once again delivers a well-made business notebook.

The notebook features a latest-generation Kaby Lake Core i7 processor that should easily meet most users' requirements. It is more than adequate for office and internet use. The dedicated GeForce GPU is useful for graphically intensive applications.

The device does not heat up too much and is very quiet when idle. Unfortunately, it suffers from coil whining in certain scenarios (e.g. transferring large amounts of data). It is very fast thanks to its SSD, and offers an additional 1 TB 2.5-inch hard drive to boot. Both storage devices are user replaceable: while the HDD is hidden behind a dedicated maintenance flap, the case must be opened in order to replace the SSD.

The matte IPS display offers very good viewing angles as well as decent contrast levels and color accuracy. Unfortunately, brightness is a bit too low for our taste, and brightness distribution is also rather uneven. Shortcomings, that are not acceptable given the device’s high price.
