惠普ProBook 445 G8在审查。安静的办公笔记本电脑与AMD Turbo
与EliteBook 800系列一样，惠普的ProBooks也属于商务中端产品系列，但它们只提供相应的功能基础。我们的模型配备了一个AMD Ryzen 5 5600U(Zen 3)，慷慨的16GB内存，以及512GB固态硬盘。700欧元（约703美元）的价格不包括Windows。14英寸全高清IPS显示屏的额定亮度为250尼特，但也有400尼特的低功耗面板可供选择。也可以选择AMD的更强大的八核CPU。
除了性能，排放和电池运行时间与基于英特尔的兄弟姐妹机型以及AMD的前辈相比，应该是有趣的。竞争也很激烈，有 ThinkPad E14 G3竞争者还有ThinkPad E14 G3、Dell戴尔Latitude 14 5520，以及 Acer Swift 3.
由于ProBook的英特尔变体在其他方面的构造完全相同，请参考对ProBook 440 G8的评论。惠普ProBook 440 G8和它的前辈， 惠普ProBook 440 G6关于外壳、连接性和输入设备的详细信息。

惠普ProBook显示器。哑光、饱和的黑色，但太暗了
相对于VA面板的 惠普ProBook 440 G8我们的型号使用IPS面板，分辨率相同，为1,920x1,080像素，屏幕对角线为14英寸。哑光显示屏的83%的亮度分布也非常相似，位于中场。0.25尼特的黑色水平很好，1,216:1的对比度大大高于前辈和兄弟姐妹的机型。
270尼特的亮度比制造商的规格250尼特略高。这两款联想笔记本电脑以及惠普Pavilion 14是我们测试领域中唯一能够超过300尼特的产品。同样，ProBook的响应时间和所有列出的对比设备一样，都是平庸到缓慢。我们没有注意到任何PWM的闪烁。
有三种备选面板。400尼特低功耗（100% sRGB），1000尼特SureView（100% sRGB），以及250尼特1,366x768像素的面板。

色彩空间覆盖率只有sRGB范围的55.5%，这是非常低的，这意味着该显示器不适合进行雄心勃勃的图像编辑。在我们的测试领域中，只有惠普Pavilion 14能够覆盖sRGB色彩空间的90%以上。
非常高的DeltaE值的色彩精度也有很多需要改进的地方--在我们的校准之后，只有灰度等级可以达到良好的数值。尽管如此，开箱即用的红色色调现在已经成为过去。 像往常一样，我们校准过的ICC色彩配置文件可以在照明图形旁边下载。
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).

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 not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8710 (minimum: 5 - maximum: 343500) Hz was measured. | |||
由于面板有点太暗（270尼特），在户外的移动性有点受限，因为需要在阴凉处才能看清屏幕内容。仅仅是哑光的屏幕表面是不够的。
此外，用户必须在AMD的Radeon设置中停用 "Vari Bright"，以避免在电池供电时失去亮度。
即使在平坦的视角下，IPS面板仍能准确地再现屏幕内容，这与兄弟姐妹机型中的VA面板形成对比。然而，这两种技术在实践中都是比较适合的。
尽管对AMD Ryzen进行了节流，但性能令人印象深刻
AMD六核处理器的性能对于办公应用来说是绰绰有余的。ProBook 445 G8可以很好地处理所有任务，甚至是虚拟机，如果你扩展16GB的内存，并在必要时升级512GB的SSD。然而，复杂的3D应用对集成的 Vega 7 GPU.
测试条件
惠普并没有为其ProBook 445 G8提供自己的性能配置文件。因此，我们的基准和测试是使用Windows的 "最佳性能 "电源模式进行的。另一方面，浏览网页时的电池运行时间是使用 "平衡 "模式确定的。
处理器
淘宝网AMD Ryzen 5600U被允许在几秒钟内使用30瓦，然后在一分钟内使用25瓦，最后保持在15瓦，这意味着性能迅速下降了20%。核心时钟速度证实了这种行为，最初是3.3GHz，后来是恒定的2.6GHz。
该ThinkPad E14 G3以及华硕的ExpertBook B1尽管采用了较早的Zen 2架构，但提供了更好的长期性能。尽管如此，惠普ProBook 445仍然在CPU性能评级中名列前茅。特别是在 "Octane V2 "和 "Jetstream 2 "网络浏览基准测试中，Zen 2 CPU的性能比其高出整整30%。
由于CPU在达到PL1极限后坐在舒适的60°C（约68°F），而且风扇几乎听不到声音，我们希望看到25瓦的长期耗电量。然而，寻求更多性能的用户仍然可以选择AMD的八核CPU，如 Ryzen 7 5800U.另一方面，Ryzen 3 5400U(四核)更实惠。在电池电量上没有性能下降。

DPC延迟
由于延迟几乎为0.7毫秒，在实时应用中会出现问题。主要的罪魁祸首是Wi-Fi驱动程序，如果你自己的工作不需要它，你可以在必要时停用它。惠普应该通过BIOS更新来改善这个问题。

图形卡
惠普ProBook 445 G8使用集成的 Vega 7图形，在这一点上，单通道内存的缺点变得很明显。能够诉诸双通道内存的Vega 7 iGPU在基准测试中的表现要快30%-40%。
在游戏中，这种差异通常更加明显，在我们的比较领域，它最多可以击败自己的前辈。这款办公笔记本电脑一般不是为游戏而设计的；只有低细节水平的老游戏可以顺利享受。
Witcher 3》中的性能会有一些波动，但不会随着时间的推移而降低，也不会因为电池电量而降低性能。

排放。其强大的冷却系统使ProBook成为一个安静的执行者
噪声排放
惠普ProBook 445是人们希望在办公室使用的最安静的笔记本电脑之一。即使在综合压力测试中，也几乎听不到风扇的声音，最大声压级为30.7分贝（A），甚至在达到功率限制2后还会下降。
这是非常安静的，即使在苛刻的网络浏览过程中，风扇也不会启动。也没有线圈的啸叫。只有ThinkPad E14 G3才能够跟上这种安静程度--仅仅是这样。

温度
尽管性能极其安静，但温度也在绿色范围内。在设备的顶部甚至感觉不到轻微的温度上升。
在CPU压力测试中，2.3GHz的基本时钟速度被保持。在综合负载（Prime95+FurMark）下，时钟速率进一步下降（1.9 GHz）。GPU核心时钟从1800MHz下降到600MHz，但这种情况在日常使用中不会发生。这里的温度仍然非常适中，约为60℃（约140°F），这意味着保守的功率限制生效，而不是热节流。

能源管理。HP ProBook 445通过节流来节省能源
能源消耗
惠普ProBook在负载和游戏时的功耗约为27瓦，特别低，这只是由于AMD APU的长期功率限制为15瓦。ProBook的空闲功耗与竞争对手持平。
附带的45瓦电源适配器有足够的能力长时间运行，但它不能完全处理压力测试中高达46瓦的初始负载峰值；然而，压力测试与用户在日常使用中的情况相差甚远。

电池寿命
惠普ProBook 445可以管理大约10小时的网络浏览。我们在显示屏亮度为150尼特、Windows性能模式设置为 "平衡 "的情况下进行测试。结果，它明显超过了其英特尔CPU兄弟姐妹机型的7:30小时。笔记本ThinkPad E14和戴尔Latitude 14由于采用了容量更大的电池，持续时间甚至更长。
要给电池快速充电，你需要惠普的65瓦电源适配器。

Pros
+ AMD CPU提供了大量的性能
+ 良好的电池寿命
+ 非常安静
+ 坚固耐用
+ 带红外和快门的网络摄像头
+ 带有Power Delivery和DisplayPort的USB-C
+ 易于维护，加上2个SO-DIMM
Cons
- 小色彩空间的昏暗显示
- 单通道内存降低了图形性能
- 没有Thunderbolt
- Wi-Fi 5 (Realtek)
- 只有12个月的保修期
结论，惠普ProBook 445 G8：移动办公，快速、安静的操作
惠普ProBook 445 G8是其强大的前辈的合理升级，由于AMD Zen 3，它提供了巨大的性能，超越了普通的办公任务。结合深思熟虑的冷却系统，它也导致了非常安静的办公室操作。而电池运行时间也同样受益于AMD芯片。这使得ProBook成为移动办公的完美选择，而良好的输入设备也对此有所贡献。
惠普ProBook 445 G8采用AMD Zen-3提供了出色的CPU性能，它在所有核心方面都能超过基于英特尔的兄弟机型。
尽管如此，惠普故意将CPU的功率限制在15瓦，从而使其性能下降了25%；制造商在这里倾向于使用安静的工作设备。同样遗憾的是，用于快速充电的65瓦电源适配器没有包括在内，而且我们的模型只配备了Wi-Fi 5模块。最大的缺点是显示屏太暗，这就是为什么你应该留意400尼特的选项。另外，联想 ThinkPad E14 G3 AMD提供了更好的键盘，更长的电池寿命和更高的长期性能--但最重要的是，ThinkPad的显示屏更亮。
