富士通LifeBook U9311X评测--带LTE的1公斤商务敞篷车

Name: Fujitsu LifeBook U9311X i7 LTE
Brand: Fujitsu

现在有了Tiger Lake 和Thunderbolt 4。

富士通现在为其轻型商务敞篷车配备了最新的Tiger Lake 处理器和Thunderbolt 4，但保留了熟悉的外壳和16：9屏幕。尽管更新了硬件，Lifebook U9311X现在感觉有点灰尘。

外壳、设备和输入装置

我们已经知道两个前辈机型的镁合金外壳，即U9310X和U939X.它仍然是一款移动性极强的商务便携机，包括手写笔在内的重量刚刚超过1公斤（约2.2磅），但你可以看到外壳的老化，特别是在宽大的屏幕边缘和（以今天的标准）微小的触摸板。如果我们的测试设备的红色外壳太显眼，U9311X也有黑色版本。

一个优势是广泛的连接，包括一个完整的SD读卡器，甚至一个千兆以太网端口。Thunderbolt 4现在也支持Tiger Lake 更新。还支持高传输率的Wi-Fi 6，还安装了一个LTE模块，但更现代的选择（Wi-Fi 6E和5G）在这里也已经有了，这对于2300欧元（约2716美元）的价格来说是可以期待的。

键盘是有照明的，但它仍然是一个小的弱点。键盘相当小，压力点也相当松软。惠普或联想的其他商务转换机在这里只是提供更好的输入。

显示屏 - Lifebook配备16:9的IPS触摸屏

13.3英寸IPS触摸屏也没有变化，分辨率为1080p（16:9），表面防反射，因为富士通依靠的是与去年一样的面板。画面的主观印象仍然很好，但只要亮度在30%或以下，就仍然有PWM。光晕不是一个大问题，只有在下部两个角落有轻微的增亮。

sRGB色彩空间被完全覆盖，经过校准后，该面板也适用于编辑图片/视频。然而，该面板在出厂时就已经调整好了，对于生产任务来说，额外的校准是没有必要的。亮度约为350cd/m²，对比度也不错。尽管如此，你必须注意户外的反射，否则就不可能舒适地使用。IPS面板的可视角度稳定性非常好。

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
37.6 ms ... rise ↗ and fall ↘ combined	↗ 18.8 ms rise
37.6 ms ... rise ↗ and fall ↘ combined	↘ 18.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 95 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
61.2 ms ... rise ↗ and fall ↘ combined	↗ 32 ms rise
61.2 ms ... rise ↗ and fall ↘ combined	↘ 29.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 96 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 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

211.9 Hz

≤ 30 % brightness setting

The display backlight flickers at 211.9 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 30 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 211.9 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8743 (minimum: 5 - maximum: 343500) Hz was measured.

性能、排放和电池寿命

富士通使用快速的酷睿i7-1185G7(Tiger Lake)，它也支持vPro。理论上，这个处理器可以管理非常高的时钟频率（高达4.8 GHz），但这种潜力几乎没有得到利用。该处理器允许在短时间内消耗40瓦，但几秒钟后就只有22瓦了。因此，与以前的处理器相比，这里没有真正的优势。最大的优势是改进的集成显卡，现在可以用来做一下游戏。然而，与前代产品相比，在电池模式下性能仍然稳定。

总的来说，系统性能非常好，这也要归功于快速的PCIe-SSD（3.0 x4），设备实现输入没有明显的延迟。在我们的标准化延迟测试中，该测试设备也没有显示出任何限制。

在温度方面没有任何限制，但是风扇在负载期间启动得相当快，而且还能清楚地听到，特别是在CPU高负载期间，但在日常办公中通常保持停用状态。没有恼人的电子噪音，如线圈啸叫。扬声器相当弱，现在许多商务设备提供的功能要多得多。

在实际的WLAN测试中，电池寿命为7-8小时，这取决于亮度，比前代产品略差。其原因可能是电池模式下的性能，在U9311X中不再降低。

结论--富士通的敞篷车需要重新设计

从去年的飞跃的飞跃，从去年的Lifebook U9310X(或更早的 U939X)到现在的Lifebook U9311X的飞跃是相当小的。富士通确实使用了英特尔当前的Tiger Lake 处理器，两个USB-C端口现在支持Thunderbolt 4，但其他一切都保持不变。

镁合金外壳仍然很轻，并提供广泛的端口，但16:9的屏幕包括宽大的屏幕边框以及小的触摸板显示了外壳的年龄。键盘也不得不向其他商务设备认输。

Lifebook U9311X仍然是一个紧凑的移动伴侣，包括LTE，但你会慢慢注意到设计的年龄。我们希望看到下一代的16:10屏幕和更好的输入设备。

总而言之，U9311X自然仍然是一个具有良好连接性的极致移动伴侣。特别是在显示和输入设备方面，竞争对手如联想ThinkPad X13 Yoga G2或惠普的EliteBook Dragonfly Max往往能提供更多。此外，性能产量有点令人失望，i7-1185G7的全部潜力根本无法发挥出来；采用酷睿i5的廉价版本在实践中应该没有什么大的缺点。
