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。

我们的模型配备了一个插入式Realtek Wi-Fi 5模块,包括蓝牙5.0。然而,在发送数据时,它只比配备英特尔AX201(Wi-Fi 6)的兄弟姐妹机型慢(283 MB/s)。戴尔的Latitude 14 5420和联想 IdeaPad 5 14总体上实现了快得多的传输速率。带WWAN的型号不适用。

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。

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。

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
Cons
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。
