惠普EliteBook 840 G9笔记本电脑评测。联想ThinkPad X1 Carbon的替代品
EliteBook 840 G9是EliteBook 845 G9的英特尔版本,我们最近曾在两种不同的配置中对其进行了评测。在这个评论页面,我们将重点关注EliteBook 840 G9 Core i7-1280P配置的性能,因为关于机箱、键盘、可维修性和其他物理属性的细节可以在我们的 现有的AMD评测页面.
由于EliteBook集成了更多的可选功能,所以SKU的选择要比大多数消费类笔记本电脑广泛得多。CPU的范围从Core i5-1250P到Core i7-1280P,250-nit到1000-nit显示器,以及8到64GB的内存和其他辅助选项,如图所示。.我们的特定评测单元配备了最高级别的酷睿i7-1280P处理器,但配备了中级别的400尼特面板和16GB内存,价格略低于3000美元。
EliteBook 840 G9的替代品包括其他旗舰级14英寸商务副本,如 联想ThinkPad X1 Carbon Gen 10或 戴尔Latitude 9430或 Latitude 7420.

外壳 - 与EliteBook 845 G9相同
虽然机箱在视觉上与EliteBook 845 G9相同,但只要看一下左侧边缘的USB-C端口,就能轻易区分这两种型号。840 G9的端口旁边会有一个Thunderbolt标签,而由AMD驱动的845 G9由于缺乏支持,完全省略了这个标签。
对于维修,惠普有一个,整个视频指南从头到尾介绍了如何拆卸和更换该机型的每个主要部件。这是我们希望其他主要制造商在未来能够效仿的做法,以消除终端用户的所有猜测。
沟通
英特尔AX211是大多数840 G9配置的标准配置,因为这毕竟是一个由英特尔驱动的系列。相比之下,由AMD驱动的845 G9采用了高通Fast Connect 6900来提供同样的Wi-Fi 6E功能。根据我们对华硕AXE11000路由器的测试,两者的整体性能相当。
广域网是可选的,可以选择英特尔XMM 7560 R+ LTE或5000 5G。

网络摄像头
5MP网络摄像头可能没有最近的8MP网络摄像头那么清晰。 蜻蜓书桌G3但它仍然明显优于大多数其他笔记本电脑上的1MP或2MP网络摄像头。在这方面,惠普已经走在了前列。
网络摄像头滑块快门是增加隐私的标准配置,而支持Hello的红外传感器是可选的。
配件和保修
除了交流电适配器和文件之外,零售盒中没有任何额外的东西。令人失望的是,标准保修期只有一年,而大多数竞争性的戴尔Latitude ,则是三年。
显示屏 - 颜色很好,响应时间慢
惠普提供七种不同的面板选择。
- 250尼特,无WWAN
- 250尼特,WWAN
- 400尼特,低蓝光,无WWAN
- 400尼特,低蓝光,WWAN
- 250尼特,触摸屏,无WWAN
- 1000尼特,低蓝光,Sure View,WWAN
- 250尼特,触摸屏,WWAN
- 1000尼特,低蓝光,Sure View,无WWAN
我们下面的测量结果只反映了上面加粗的选项。值得注意的是,所有的面板都是1920 x 1200雾面IPS 60 Hz,没有OLED选项。不幸的是,无论用户是否喜欢,Sure View都与1000尼特的面板选项联系在一起。
除了上述限制,我们单位的奇美面板在色彩覆盖和对比度方面是一个高品质的面板。它最大的缺点是黑白和灰白的反应时间非常慢,有明显的重影现象。虽然在办公室或以商业为中心的笔记本电脑上并不罕见,但它们在这里却慢得惊人,以至于在浏览网页或视频流时都会分心。

性能 - 最快的Core i7 P系列选项
测试条件
在运行以下任何基准测试之前,我们通过Windows将我们的设备设置为 "最佳性能 "模式。奇怪的是,预装的电源管理器应用程序不包括任何额外的电源设置,与我们在最近的Dragonfly Folio G3上看到的不同。
处理器
由于系统的Turbo Boost潜力有限,CPU的性能是一个混合包。例如,当循环运行CineBench R15 xT时,最初的1992分在运行一次后会明显下降到1458分,表示性能下降了27%。这一降幅比大多数其他笔记本电脑,甚至包括许多酷睿U系列机型都要大。相比之下,Ryzen 9 PRO 6950HS在整个压力测试中,EliteBook 845 G9的性能结果稳定。
许多其他具有相同 酷睿i7-1280P由于其更强大的冷却解决方案,能够提供比我们的惠普更快的性能。较大的 MSI Summit E16 Flip例如,它的多线程性能比我们的EliteBook 840 G9快25%到50%。

GPU性能 - 高于平均水平的Iris Xe 96 EUs
尽管酷睿i7-1280P采用了相同的集成式 Iris Xe 96 EUs虽然酷睿i7-1165G7或酷睿i7-1265U采用了相同的集成Iris Xe 96 EUs图形处理器,但由于Core-P CPU具有更高的热包络,所以惠普的图形性能略快。因此,用户可以期待比一般Iris Xe 96 EU驱动的笔记本电脑快15%到25%的帧率。降级到酷睿i5配置的 Iris Xe 80 EUs将会导致图形性能下降20%到30%。
有趣的是,我们的英特尔GPU的性能超过了竞争对手的 Radeon 680M尽管Radeon 680M在其他笔记本电脑上运行得更快,如EliteBook 845 G9。联想Yoga 7 14.很明显,EliteBook中的集成Radeon GPU表现不佳。

系统噪音
风扇的噪音和行为与我们在该型号的AMD版本上记录的情况类似。在运行较重的负载时,内部风扇在尽可能长时间地保持空闲方面做得很好。例如,运行一次3DMark 06的第一个基准场景,在24dB(A)的无声背景下,风扇噪音仅为32dB(A)。在反复运行后,风扇最终会稳定在39dB(A)左右,只有暂时性的脉冲,最高可达45dB(A)。总的来说,风扇的噪音比我们在去年的EliteBook 840 Aero G8上记录的还要大。 EliteBook 840 Aero G8它使用的是较慢的第11代酷睿U系列CPU。

压力测试
当运行Prime95时,CPU将提升到3 GHz和60 W,持续约20秒或直到核心温度达到86 C。此后,它将下降到只有1.6 GHz和30 W,以保持65 C的冷却核心温度。
运行时的GPU时钟速率和温度 Witcher 3将分别稳定在1397 MHz和66 C,相比之下,1097 MHz和65 C在 蜻蜓笔记本G3配备了相同的集成GPU。更高的时钟速率有助于推动EliteBook在图形性能方面超过大多数Core U供电的笔记本电脑。
用电池供电运行会稍微降低性能。在电池上进行的3DMark 11测试将返回物理和图形分数,分别为13157和6717分,而在主电源上则为15376和7101分。

消耗功率
我们下面的对比表显示,AMD版本比我们的英特尔设备要求更高。然而,这种差异主要归因于AMD版本的1000尼特面板,而我们的英特尔版本使用的是要求较低的400尼特面板。在桌面上以最大亮度设置空转,英特尔和AMD的设备将分别消耗约9W和18W。当考虑到这一点时,尽管两款机型在性能上存在差异,但其总体功耗差异变得更加微小。
在运行Prime95压力时,我们能够从小型(约8.8 x 5.3 x 2.1厘米)的65瓦交流适配器上记录到68瓦的最大功耗。如下图所示,由于散热限制,这一速率只是暂时的。

电池寿命--比AMD略短
当两者都设置为150 nit亮度和平衡电源配置文件时,WLAN运行时间比我们在AMD驱动的EliteBook 845 G9上记录的时间短了近两个小时。即便如此,7.5小时的连续浏览对大多数用户来说应该是令人满意的。
从空电到满电的充电速度很快,大约90分钟。第三方USB-C充电器在技术上是支持的,但如果它们的输出水平与所附的惠普充电器(20V/3.25A)不匹配,许多充电器就不能保证工作。

结论--好处和坏处
酷睿i7-1280P EliteBook 840 G9能否在Ryzen 9 Pro 6950HS面前站稳脚跟? EliteBook 845 G9?就原始的CPU潜力而言,AMD型号是一种方式,因为它的性能不会像英特尔型号那样被扼杀。然而,在图形性能方面,AMD模型中的Radeon 680M似乎表现不佳,以至于落后于Iris Xe 96 EUs。因此,更好的选择将取决于你的具体工作负载的CPU或GPU密集度如何。
除了处理器的差异外,AMD机型的电池寿命更长,而英特尔机型则得益于对Thunderbolt的支持。不幸的是,Sure View被强制安装在所有1000尼特的面板选项上,因为一些用户可能根本不想要这个隐私功能,因为它对图像质量的影响甚至在关闭时也是如此。对于未来的机型,我们希望看到面板有更快的响应时间,以减少重影,也许有更高的核心温度上限,以挤出更多的英特尔CPU的涡轮增压性能。
