惠普ProBook 440 G9评论。高效的酷睿i7-1255U笔记本电脑，没有闪耀的光芒
我们测试的HP ProBook 440 G9提供了很多熟悉的功能。特别是，与它的前辈相比，外观似乎几乎没有变化。惠普ProBook 440 G8.关于机箱和输入设备的更多信息可以在之前链接的ProBook 440 G8的评论中找到，但我们在这里只顺便提一下。
现在安装的是IPS面板而不是VA面板，尽管我们的测量结果很难激起任何热情。
然而，这还不是全部。惠普主要承诺的是快速的性能，即使在高负荷时也有低排放，以及存储数据的大量安全性。中小型企业特别购买了ProBook的额外安全功能，他们自己的IT部门无法接管。否则，企业也可以选择更强大的笔记本电脑，价格仅超过1,000欧元，如 联想ThinkBook 14 G4.
在测试中，ProBook 440 G9配备了 英特尔酷睿i7-1255U，16GB内存和512GB M.2固态硬盘，显示了与前代产品相比，ProBook 440 G9的改进或新的弱点在哪里。笔记本 440 G8或采用AMD处理器的版本 配备AMD处理器的ProBook.

外壳和设备。ProBook的端口选择有限
ProBook 440 G9的机箱采用了铝制盖子和键盘框架，很稳定，抗扭。它看起来也是精确制造的，不存在任何视觉上的突出问题。
端口的选择是有限的。Thunderbolt或SD读卡器完全没有，而LAN端口只达到1 Gbit/s。只有USB Type-C至少达到10Gbit/s。作为一个基本选择，它是可以的。
一个内存插槽和一个用于第二个M.2 SSD或WWAN模块的插槽在里面仍然是空闲的。主要的固态硬盘、电池、WLAN模块和完整的工作存储器是可以更换的。访问内饰与其他惠普笔记本电脑类似，几乎不费吹灰之力就能完成--只需卸下五个裸露的螺丝。
通信、软件和输入设备。惠普提供广泛的安全和服务软件
ProBook的一大优点是其提供的软件。惠普提供了一整套程序，始终确保最新的驱动程序，并能检测各种软件冲突。HP Wolf Security是一个全面的安全包。基本上，一切都包括在内，从通过内置的沙盒浏览器保护恶意软件到受保护的硬件，有助于在受到攻击后恢复原始系统。相关的许可证必须在一年后更新。
由于有了Wi-Fi 6E，即使有大量数据，数据传输也非常快。如果与路由器的距离足够小，甚至局域网电缆也会更慢。这种差异是巨大的，特别是与 惠普ProBook 445 G8配有AMD处理器。
两级背光键盘不是很突出。它适用于快速打字，但不比大多数小键盘好。
网络摄像头对极暗的场景也有很好的亮度，令人信服。图像噪音也保持得很好，而720p网络摄像头的整体图像质量很弱。 色彩偏差是存在的，但不是很明显。一个双阵列麦克风总是以体面的质量和相对稳定的音量记录声音，但它听起来很尖锐。然而，这对于旅途中的视频电话来说是完全足够的。
此外，还安装了一个物理快门以覆盖镜头。在网络摄像头旁边还有一个红外线摄像头，用于通过面部识别解锁。它的工作原理完美无缺，应该会使指纹扫描仪变得有些多余。

显示。不要用惠普的商务笔记本做创意工作
ProBook 440 G9提供的画面足以满足写作、阅读和工作的需要。14英寸对角线上的全高清分辨率提供了详细的图片。然而，这些图片既不是色彩非常丰富的，也不是特别明亮的。调色板最多只能满足正确显示图片和图形的需要，但在简单的图像编辑中已经会被过度消耗了。
只要没有直接的光线落在工作站上，略低于250cd/m²的亮度在室内总是能有良好的可读性。在电池模式下，背光被降低到最低限度，因此只有在阴暗的地方，特别是在户外才能充分阅读文本。相反，在阳光下，屏幕内容几乎被隐藏起来。

然而，对于ProBook这样的经典工作设备来说，这并不是一个缺点。
性能。ProBook 440 G9配备了酷睿i7，性能良好
的 英特尔桤木湖酷睿i7-1255U在看硬件时，这款处理器非常突出。此外，有足够的16GB工作内存和一个大小合适的512GB固态硬盘。然而，内存仍然是DDR4。固态硬盘以PCIe 3.0速度运行。
两者都不会降低处理器的速度，这确保了所有的任务--即使是那些并行执行的任务--都能得到快速处理。一个dGPU被完全省略了。该 英特尔Iris Xe 96EUs可以很好地管理要求不高的图形应用程序。然而，对于游戏或视频渲染来说，它太弱了。
处理器
的英特尔酷睿i7-1255U并不回避苛刻的任务。两个性能核心和八个效率核心，以及由此产生的十二个线程，确保了高计算能力。
惠普还为ProBook 440 G9的CPU提供了高于标准的功耗。例如，虽然 惠普ProBook 450 G9被允许在较长时间内使用15W，而在这里，相同的CPU以24W运行。在一瞬间，它甚至被允许消耗51瓦，而不是像大机型那样只有39瓦。这种瞬间的功率增加是该CPU在Cinebench R15多核循环测试等基准测试中的明显优势。
另一方面，在电池模式下，功耗被限制在12W（28秒）和17W（2.44ms）。
这导致在我们的CPU基准测试中，性能率一直高于ProBook 450。然而，对效率要求不高的笔记本电脑可以从酷睿i7中获得更多的性能，如 惠普Spectre x360.

DPC延迟
大容量存储
三星的M.2固态硬盘，以30Gbit/s的速度连接，表现低于其能力。在耐久性测试中，它只能在短时间内达到3000MB/s，这接近于可能的最大值。然后，它变得太热，并节制了读取速度。然而，这种行为在正常使用中应该不会有太大影响。
从积极的方面来看，第二个插槽是免费的，用于存储扩展。一个M.2-2280固态硬盘也可以用来代替WWAN模块。

排放和能源。HP ProBook 440 G9的静音操作
ProBook在电池模式下和连接到电源时都保持安静。就能源消耗而言，它在负载下的要求也不高。
我们观察到，如果风扇在高负荷时打开，背景中只有可察觉的噪音。速度变化并不令人不快。
在正常使用中，表面升温是不明显的。我们的测量显示，在低负荷时，与周围环境相比，表面温度仅增加了5℃。在最大负荷下，温度上升了15°C，但只是在CPU区域附近。特别是手掌部位，只是轻微升温。
无负载时的功耗似乎有点太高。尽管有一个高效的CPU和一个要求不高的显示屏，但总是要消耗至少5W。
对于简单的任务，如网上冲浪，ProBook的Core i7几乎不需要发挥自己的作用。尽管电池很小，但至少可以接受近6小时的运行时间。
然而，具有类似容量的竞争者在这方面显然做得更好。联想联想ThinkBook 15 G4配备了稍微强大的 AMD Ryzen 5 5625U可以多冲浪2个小时以上。

结论：ProBook 440 G9被证明是坚实、安全和快速的。
作为一台用于重要商业任务的笔记本电脑，惠普ProBook 440 G9提供了完全正确的功能，仅此而已。凭借稳定的外壳、生物识别登录选项和广泛的安全软件，ProBook 440 G9可以很好地作为敏感数据的工作设备使用。
与上一代产品惠普ProBook 440 G8相比，由于采用了英特尔Alder Lake处理器，计算能力有了很大的提高。然而，与采用英特尔Tiger Lake 架构的机型相比，CPU的耗电量也相应增加。电池寿命也降低了--运行时间略低于6小时，仍然可以接受，但与拥有类似小电池的竞争对手相比，它并不多。
惠普ProBook 440 G9的特点是：自己的数据安全，速度快，风扇安静得令人愉快，但其他设备绝对不多。
在写作、研究和数字计算时，ProBook处于最佳状态。风扇的声音很少。在没有电源连接的情况下，笔记本保持沉默，升温也不明显。令人愉快的键盘使其能够精确而快速地工作。
除此之外，惠普几乎在所有其他方面都偷工减料。尽管采用了IPS面板，但低亮度和色彩不佳的显示屏尤其如此。即使是看照片也不一定是个值得推荐的活动。此外，电池模式下亮度的降低使得在户外工作几乎不可能。
另外，720p的网络摄像头为视频电话提供了足够的图片质量。在端口中，只有最必要的那些。Thunderbolt、读卡器或专有对接端口都没有。
如果安全包对日常工作很重要，那么值得购买稳定且速度令人满意的惠普ProBook 440 G9商务笔记本。否则，联想ThinkBook 14 G4会提供多得多的计算能力和更有说服力的整体包装。这款 Acer Aspire Vero AV14也使用英特尔酷睿i7-1255U，这将更适合创意工作，以及其他事情。
