外壳和功能。EX215没有USB-C接口
Extensa并非由高质量的机箱材料制成，如铝或镁。机箱是由黑色塑料制成的，但加工缺陷并不明显。底部装置和盖子似乎有更高的硬度。电池是不可拆卸的，也没有提供维护舱口。
EX215的端口选择主要包括三个USB-A端口（1个USB 2.0，2个USB 3.2 Gen 1）。可以通过HDMI连接外部显示器。宏碁在笔记本电脑中包括一个USB-C端口和一个存储卡阅读器。
在最佳条件下确定的WLAN数据率（附近没有其他WLAN设备，笔记本和服务器PC之间的距离很短）似乎不能与竞争对手相提并论。这可能是由于所安装的WLAN芯片（英特尔Wireless-AC 9462）的选择，该芯片允许的最大传输率仅为433 MBit/s。
这款笔记本电脑应该与Windows 10和Windows 11兼容。然而，我们的变体没有安装Windows操作系统。宏碁为该设备配备了一个名为 "eShell "的象征性操作系统--它自己的Linux发行版。因此，完全的Linux兼容性是必然的。测试安装的Ubuntu 20.04.03 LTS（64位）运行没有问题。所有硬件都被识别和设置，所有功能键都可以使用。

输入设备。Extensa没有背光的按键
扁平的、略微粗糙的无灯小键盘的按键提供了一个短的行程和一个清晰的压力点。键盘在打字时有一点弯曲，不过事实证明这并不令人讨厌。总而言之，宏碁提供了一个适合日常使用的键盘。
一个具有多点触摸功能的ClickPad（约10.6 x 7.8厘米）可作为鼠标的替代品。其光滑的表面使手指容易滑动。该垫子也对角落里的输入作出反应。它有一个短的行程和一个清晰的压力点。
显示屏。宏碁15有一个过时的面板
哑光15.6英寸屏幕（1,920 x 1,080像素）的亮度（203.1 cd/m²）和对比度（512:1）原来是很低的。我们认为超过300cd/m²或1,000:1的数值为好。在每个亮度水平上都会出现频率为52Hz的闪烁。这可能会导致对PWM敏感的人头痛和/或眼睛出问题。

这块屏幕的色彩再现在开箱后并不令人信服--我们观察到色彩明显偏离了目标。此外，显示屏还存在偏蓝的问题。校准可以消除偏蓝的现象，并确保体面的色彩再现。该显示器不能充分覆盖AdobeRGB（38%）、sRGB（56%）和DCI-P3（37%）色彩空间。
Display Response Times
ℹ
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 | ||
|---|---|---|
| 21 ms ... rise ↗ and fall ↘ combined | ↗ 17 ms rise |  |
| ↘ 4 ms fall | ||
| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 40 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (21.5 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 38 ms ... rise ↗ and fall ↘ combined | ↗ 18 ms rise |  |
| ↘ 20 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 49 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
ℹ
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 | 52 Hz | ≤ 100 % brightness setting |  |
The display backlight flickers at 52 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 52 Hz is very low, so the flickering may cause eyestrain and headaches after extended use. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17915 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
TN面板的可视角度不稳定，因此不是在每个位置都能读懂。如果太阳不是太亮的话，在户外阅读屏幕是差不多的。否则，低的显示亮度在这方面没有多大帮助。
性能。宏碁依靠的是Tiger Lake
宏碁通过Extensa 15 EX215-54提供了一款15.6英寸规格的简单办公笔记本，为办公和互联网应用提供了足够的计算能力。
测试条件
我们使用了Windows中的 "平衡 "能源配置文件，因为其他能源模式不可用。该模式下的CPU功率限制为28W（PL1）和64W（PL2）。
处理器
芯片 酷睿i5-1135G7四核处理器（Tiger Lake ）的基本时钟为2.4 GHz。通过Turbo Boost可以提高到3.8 GHz（所有核心）或高达4.2 GHz（一个核心），而且还支持超线程（每个核心两个线程）。Cinebench R15测试在3.4至3.8 GHz（多线程），或2至4.2 GHz（单线程）下运行。在电池模式下，时钟速率明显降低。
我们通过运行Cinebench R15基准测试的循环多线程测试至少30分钟，检查CPU提升是否在直流电力运行时被永久使用。四个CPU核心中的三个以基础时钟附近的平均值运行。第四个核心以升压频率持续工作。

系统性能
在我们的测试中，这个灵活而流畅的系统没有造成任何问题，而且该设备在PCMark中也取得了良好的成绩。CPU为办公和互联网应用提供了足够的性能。由于焊接的工作存储器（8GB）只在单通道模式下运行，一些计算能力没有得到发挥。幸运的是，笔记本内部仍有一个未被占用的工作存储器库。双通道模式可以通过安装一个内存模块来激活。

图形卡
英特尔的 Iris-Xe-Graphics-G7 80 EUsGPU实现了高达1300MHz的工作时钟，正如TheWitcher 3测试所证明的那样，它可以持续保持。Extensa不是一款游戏笔记本。然而，安装的硬件可以在低分辨率和低质量设置下流畅地渲染一些游戏。对硬件要求适中的游戏，如《Dota 2》。重生》等对硬件要求适中的游戏应该可以在这台笔记本电脑上以低到中等的设置播放。
由于工作内存只在单通道模式下运行，因此GPU的性能远低于其能力。启用双通道模式（即安装一个内存模块）将提高基准测试结果和游戏中的帧率（见下面的对比表）。

噪声排放
在日常工作中（办公室、互联网），风扇不会转起来，操作起来一般很安静。在负载情况下，声压级上升到50 dB(A)，这对一个简单的办公笔记本来说是相当高的。竞争对手在这方面的表现似乎更好。

温度
这款15.6英寸的笔记本电脑发热量不大。在压力测试中，有两个测量点的温度超过40摄氏度。在日常使用中（办公室、互联网），温度都在绿色区域内。CPU的温度也没有显示出任何值得关注的原因。
在压力测试的开始阶段（Prime95和Furmark至少运行了一个小时），CPU以3.1至3.5GHz的时钟工作。此外，时钟在1.4和2.1GHz之间下降。图形核心的时钟在1,100至1,300MHz之间。
值得注意的是，我们的压力测试代表了一种极端情况。我们用它来检查系统是否在全负荷下稳定运行。

能源消耗
在压力测试开始时，达到了略低于45W的最大功耗。几秒钟后，由于CPU降低了时钟，这个数值就下降了。笔记本在通过TheWitcher 3测试时，耗电量稳定。电源的额定功率为45W。

评语：坚实的办公机器
A酷睿i5-1135G7-CPU、8GB工作内存和256GB NVMe固态硬盘，使宏碁Extensia EX215适合办公和互联网使用。噪音和热量排放处于中等水平。一次电池充电足以使无线局域网运行时间略低于7小时--这是一个合理的但不是一个出色的运行时间。
宏碁在Extensa 15 EX215-54上依靠的是一个令人失望的屏幕。
Tiger Lake Core i5处理器和略低于500欧元的相对适中的价格标签相结合，使Extensa具有一定的吸引力。每欧元的性能相对较高，但你将不得不在其他方面做出妥协。
也许，主要的缺点是显示屏。宏碁选择了一个视角不稳定的TN显示屏，它也只提供低亮度和低对比度。色彩空间覆盖率和色彩再现也没有说服力。更糟糕的是，该面板在每个亮度水平上都显示PWM闪烁。
由于该设备交付时没有Windows操作系统，Linux可以是一个不错的选择。Ubuntu 20.04.03 LTS（64位）可以顺利安装--整个硬件都能被识别，并且很容易设置，包括所有功能键。
Extensa的另一个选择是 联想Ideapad 3 15ALC6.它提供了一个明亮的、高对比度的IPS屏幕，具有稳定的可视角度，有一个背光键盘，而且电池运行时间明显更好。
价格和可用性
宏碁Extensa EX215的测试配置（Core i5-1135G7, 8 GB RAM, 256 GB SSD, no Windows）为486.30欧元（约552美元），在Office-Partner.de。.Cyberport.de笔记本电脑的价格为536欧元（约合人民币608元）。
