Case and connectivity - Acer workstation without Thunderbolt 3
The matte black case (snow-white models are also available) of the Acer workstation consists of a mix of metal (back of the lid, top of the base unit) and plastic (bottom cover, display frame). The laptop looks well manufactured and doesn't reveal any serious stability deficiencies. The battery is firmly built into the device. There is no maintenance hatch.
The workstation doesn't have a Thunderbolt 3 port. Acer has only used a simple USB Type-C port (USB 3.2 Gen 1), which doesn't even offer the DisplayPort via USB-C functionality. In addition, there are three USB Type-A ports (2x USB 3.2 Gen 1, 1x USB 2.0). An external display can only be connected via HDMI. A memory card reader is also missing.
The WLAN chip (Intel Wi-Fi 6 AX200) supports the fast ax standard. The transfer speeds obtained under optimal conditions (no other WLAN devices nearby, short distance between laptop and server PC) are very good.
Port configuration
Input devices - Acer CN315 with keyboard backlighting
The flat, smooth keys of the backlit chiclet keyboard offer a short travel and a clear pressure point. The resistance provided by the keys is pleasing. The illumination (one brightness level) is switched on and off with a function key. All in all, Acer delivers a keyboard suitable for everyday use here. The multi-touch capable ClickPad occupies an area of about 10.6 x 7.8 cm. The smooth pad surface makes it easy for the fingers to glide on it. The pad also reacts to input in the corners. It has a short travel and a clear pressure point.
Display - IPS with Pantone certification
The ConceptD 3 Pro's 15.6-inch matte screen operates at a native resolution of 1920x1080 pixels. The brightness (309.3 cd/m²) and contrast (1559:1) are good. Positive: The display shows no PWM flickering.

Out of the box, the display's Pantone certification guarantees a good color reproduction. With a color deviation of 3.74, it just misses the target (Delta E less than 3) and doesn't suffer from a blue tint. Calibration provides for some improvements. As a result, the deviation drops to 1.43, and the grayscales are displayed in a more balanced way. The AdobeRGB color space (78%) is not completely reproduced. The sRGB color space (100%) looks much better.
Acer equips the workstation with a viewing-angle stable IPS panel; therefore, the screen can be read from any position. The display can definitely be read outdoors when the sun isn't shining too brightly.
Performance - Acer computer comes with mid-range hardware
With the ConceptD 3 Pro CN315-71P, Acer has a 15.6-inch workstation in its range that offers enough computing power for all common applications. The test device provided to us is available from about 1,550 Euros (~$1,754). Other configuration variants are available.
Processor
The ConceptD is powered by a Core i7-9750H hexa-core processor (Coffee Lake refresh). The CPU operates at a base speed of 2.6 GHz. With Turbo, the clock speed can be increased to 4 GHz (six cores), 4.1 GHz (five cores), 4.2 GHz (four cores), 4.3 GHz (three cores), 4.4 GHz (two cores) and 4.5 GHz (one core), respectively.
When plugged in, the processor works through the CPU tests of the Cinebench R15 benchmark at 2.6 to 3.8 GHz (multithread) and 4 to 4.5 GHz (single-thread), respectively. On battery power, the speeds are 2.6 GHz (multithread) and 2.2 to 2.8 GHz (single-thread).
We verify if the CPU Turbo is also consistently used when plugged in by running the Cinebench R15 benchmark's multithread test in a continuous loop for at least 30 minutes. The results drop from the first to the second run and then stabilize at a constant level. Turbo is used at a low level.

Emissions and energy - Acer laptop provides good runtime values
Noise emissions
The ConceptD 3 Pro does not produce excessive noise over the entire load range. In idle usage, the fans are often silent, and there is no noise. But this is over under load. In this way, we register sound pressure levels of 42.4 dB(A) (stress test) and 36.9 dB(A) (The Witcher 3 test), respectively.

Temperature
The processor works through our stress test (Prime95 and FurMark run for at least an hour) for a short time at 2.6 GHz. Then the clock rate slowly drops to 1.6 GHz and remains at this level. The graphics core runs at 1,455 MHz. On battery power, the clock rates are 800 MHz (CPU) and 800 to 1,000 MHz (GPU), respectively. The stress test represents an extreme scenario that doesn't occur in everyday life. We use this test to check if the system remains stable even under full load.
The laptop warms up noticeably but not excessively. During the stress test we registered temperatures beyond 50 °C (~122 °F) at one measuring point. The heat development is even slightly stronger when performing our The Witcher 3 test. Nonetheless, the temperatures remain in the green range in everyday use.
(±) The maximum temperature on the upper side is 42 °C / 108 F, compared to the average of 38.2 °C / 101 F, ranging from 22.2 to 69.8 °C for the class Workstation.
(-) The bottom heats up to a maximum of 50.6 °C / 123 F, compared to the average of 41.2 °C / 106 F
(+) In idle usage, the average temperature for the upper side is 24.4 °C / 76 F, compared to the device average of 32 °C / 90 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 36.8 °C / 98 F, compared to the device average of 32 °C / 90 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 29.6 °C / 85.3 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.8 °C / 82 F (-1.8 °C / -3.3 F).
Speakers
The stereo speakers have been placed in the front area of the bottom of the device. They produce a decent sound, which is largely lacking in bass. In addition, the speakers only offer a low maximum volume.

Energy consumption
We measure a maximum power consumption of 10.6 watts in idle usage. During our stress test, the value increases up to 100.7 watts. In gaming mode (The Witcher 3 test), the consumption is lower at an average of 83 watts (81 to 86 watts). The power adapter's output is 135 watts.

Battery life
Our practical WLAN test uses a script to simulate the load caused by accessing websites. The "balanced" profile is active, the energy-saving functions are deactivated, and the display brightness is regulated to about 150 cd/m². The Acer CN315 reaches a runtime of 8:04 h.

Verdict
With a Core i7-9750H processor and a Quadro T1000 graphics core, this workstation is packed with up-to-date technology. Even if this isn't a gaming laptop, the built-in hardware brings all modern computer games smoothly onto the screen.
With the ConceptD 3 Pro CN315-71P, Acer has created a largely well-rounded 15.6-inch workstation that also offers good battery life.
A 512 GB NVMe SSD ensures a fast system. Should the storage space run out, it can be upgraded without issues. In addition, the laptop offers space for a second M.2 2280 SSD (NVMe/SATA) as well as for a 2.5-inch storage device.
The matte Full HD IPS display pleases with good contrast, stable viewing angles, good brightness and - thanks to the Pantone certification - great color reproduction. The sRGB color space has a 100% coverage. The Acer laptop doesn't lack stamina. Furthermore, the workstation completes our practical WLAN test after a runtime of 8:04 h. There's also a backlit keyboard that is suitable for everyday use.
We miss the inclusion of a Thunderbolt 3 port, though. This would allow the connection of a more-powerful external GPU or an extensive docking solution. Unfortunately, Acer only provides the workstation with a simple USB Type-C port (USB 3.2 Gen 1), which doesn't even offer DisplayPort via USB-C.
