Magyar惠普EliteBook 645 G9笔记本电脑评论：一个紧凑和强大的办公笔记本电脑与（未使用）的潜力
惠普的EliteBooks以稳健和高质量的商用笔记本电脑而闻名。配置为6F2Q0EA的惠普EliteBook 645 G9在我们的测试中取得了胜利，原因正是如此--即使它在功能和价格方面处于这些机型的较低范围。
这款14英寸的设备配备了AMD Ryzen 7 5825U和一个AMD Radeon RX Vega 8搭配16GB DDR4 3200单通道内存，一个512固态硬盘和LTE。另外，制造商提供的14英寸模型与不同的功能, 例如EliteBook 640 G9与Sure View隐私, 4G/LTE调制解调器和一个英特尔酷睿i5-1235U.
在我们的测试中，目前惠普EliteBook 645 G9对许多14英寸的竞争对手，包括LG UltraPC 14与相同的CPU和 惠普ProBook 440 G9由英特尔提供。

外壳和功能：流线型铝材，重量轻
惠普EliteBook 645 G9有一个光滑和符合MIL-STD810G标准的坚固外壳，由拉丝铝制成。这款14英寸设备的重量约为1.4公斤，结构紧凑，厚度不到2厘米，而且很好很轻--非常适合在旅行中携带。与其竞争对手相比，它并没有落伍。我们对该设备的构造没有什么可批评的。它的端口，包括带有DisplayPort 1.4和Power Delivery的USB 4 Type-C、HDMI 2.1和LAN，分布在笔记本电脑的两侧。电源是通过一个单独的连接器提供的。
虽然内置的高清红外网络摄像头不能夸耀可怕的色彩准确性，但由于其Wi-Fi 6E，其WLAN性能很好。如果你没有接入Wi-Fi网络，这款笔记本电脑也可以通过LTE连接到互联网，因为它有一个内置的Nano SIM卡插槽。

输入设备：一台紧凑的办公笔记本电脑，没有太多可批评的地方
直到设备的左边和右边的1.5厘米宽的框架，惠普已经利用箱子的宽度来做键盘--这对没有数字键盘的这种尺寸来说是很正常的。在16 x 16毫米左右，按键足够大，而且相当快地感觉到了打字的乐趣。有些人可能会发现组合的方向键有点烦人。指纹扫描仪就在这下面。F1至F12键具有通常的附加功能，可以控制键盘背光、屏幕亮度、音量和其他一些东西。
11.5 x 6.5英寸的触摸板位于笔记本电脑的中间，做了它在罐子上写的事情。它有一种令人愉快的感觉，并支持多点触摸手势，如双指滚动。
显示：哑光，足够明亮，适合户外使用
与竞争对手相比，这台笔记本电脑的14英寸IPS显示屏在亮度、对比度和色彩再现方面表现最好。该面板达到了略低于400流明的数值--不过，它的光线可以更均匀一些。即便如此，所取得的数值和它的哑光外观意味着它更适合在户外使用--甚至在阳光直射下。这使得EliteBook成为户外移动工作的理想选择。
反对将笔记本电脑用于专业图形编辑的一个理由是其相对较低的色彩空间覆盖结果。相比之下，它的色彩再现相当准确，是迄今为止我们比较的所有设备中最好的。它的快速反应速度和IPS典型的良好视角稳定性都很好。几乎没有任何混浊现象，但我们确实注意到了一点IPS的光亮。

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 | ||
|---|---|---|

| 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. » 32 % of all devices are better.

This means that the measured response time is better 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 not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8746 (minimum: 5 - maximum: 343500) Hz was measured. | |||
性能：EliteBook 645 G9并没有充分发挥其潜力
EliteBook 645 G9配备了AMD Ryzen 7 5825U与AMD Radeon RX Vega 8 iGPU。它的16GB DDR4 3200内存以单通道方式工作。由于有第二个SODIMM插槽，如果需要，可以升级RAM。惠普将其与512GB固态硬盘结合在一起，必要时也可以将其换掉。
测试条件
除非另有说明，否则基准测试是使用Windows性能级别 "最佳性能 "进行的。惠普没有为这款强大的商务笔记本电脑提供不同性能配置的单独工具。
处理器
已安装的AMD Ryzen 7 5825U是一款适用于紧凑型笔记本电脑的八核CPU，升压时钟高达4.5GHz，比起其他的CPU，它的时钟频率高出100MHz。Ryzen 7 5800U.该处理器有16个线程和16MB L3缓存。
我们测试设备中的处理器在基准测试中普遍落后于其竞争对手，这意味着它低于平均水平，低于LG UltraPC 14的性能，这意味着它低于平均水平，也低于采用相同芯片的LG UltraPC 14。然而，当涉及到温度和噪音排放的发展时，这确实对我们的测试样本有利，因为它们仍然很低。Ryzen 7大部分排名在中间位置，但有时也会排在底部，并刚刚超过Ryzen 5 PRO 6650U- 点，它实际上有时甚至不得不让它领先。在连续测试中，这种令人失望的结果至少在整个过程中保持一致。

系统性能
CPU没有被充分使用，加上单通道内存，意味着笔记本的系统性能结果没有什么可炫耀的。这在日常工作中并不太明显，但基准测试更清楚地显示了这一点。在这里，测试设备经常不得不向它的竞争对手认输，因为它们有时会有更强大的动力--以相当大的差距。即使是LG的竞争对手，也有完全相同的处理器，有更好的结果。

图形卡
集成的Radeon RX Vega 8 GPU有8个CU，时钟频率高达2,000 MHz，表现甚至比CPU还差。它在3DMark基准测试中取得了最后一名，在图形解决方案方面落后。
这导致了相当不令人印象深刻的游戏性能。如果游戏可以运行，那么它们只能使用最低的图形设置顺利进行。你甚至无法真正开始想象运行任何较新的游戏--但对于这种办公设备来说，这并不是一个太大的问题，与笔记本的目标市场无关。

排放和功率：一个非常安静和节俭的14英寸笔记本电脑
噪声排放
在使用中，EliteBook 645 G9被证明是很好很安静的。我们测量的27分贝与周围的环境噪音差不多，由于其关闭的冷却器，这台笔记本电脑几乎听不到。如果对硬件施加更多压力，该设备发出的最大分贝为32分贝--仍然很安静，而且冷却器几乎保持同样安静。该设备绝对比其竞争对手工作得更安静。

立体声扬声器的表现低于平均水平。虽然它们能很好地再现高音和中音，但它们的低音却很弱。这对于一个工作设备来说已经足够了。如果声音达不到你的标准，例如用于多媒体，那么你也可以通过3.5毫米音频端口连接扬声器、耳机或耳麦。

消耗功率
EliteBook 645 G9的功耗在负载下最大为45.7瓦，这意味着附带的65瓦电源的尺寸足够了。在空闲模式下，它的平均耗电量为5瓦。总的来说，审查样本比，例如，更节俭一些、LG的UltraPC 14或惠普的ProBook 440 G9采用更强大的英特尔处理器。

电池寿命
惠普的EliteBook型号配备了51.3Wh的电池。这意味着与其他设备相比，其容量低于平均水平，这反映在笔记本电脑的运行时间上。满载时约90分钟，冲浪时10小时，视频播放时超过13小时，对于一个重量不到1.4公斤的小型和紧凑的14英寸笔记本电脑来说，这些结果仍然不算太寒酸。

评语：一台有改进余地的紧凑型商务笔记本电脑
在许多方面，惠普EliteBook 645 G9在我们的测试中给人留下深刻印象。它呈现出一种优雅和紧凑，以及相对轻巧和坚固的商务笔记本电脑，也非常适合旅行。同时，其明亮的显示屏也非常适合户外使用。
在目前的配置中，EliteBook的性能有所欠缺，硬件没有发挥出最大潜力。它的性能足以满足日常使用，但对于更复杂的任务，它很可能会耗尽能量。
然而，这随后意味着笔记本电脑在使用中运行得相对安静，即使在负载下，也不会特别热。就其电池、连接性和co而言，该设备当然不会打破任何记录，但它在一天结束时仍然表现得相当好。
总的来说，惠普EliteBook 645 G9的积极方面超过了消极方面--如果你不要求对硬件有什么太大压力的话。对于目前低于1000美元的价格来说，这一点尤其真实。如果你在寻找性能更好的14英寸笔记本电脑，你应该看看联想Yoga Pro 7 或联想ThinkPad T14s 。或者你可以看看惠普EliteBook的其他配置。
