戴尔Latitude 9430二合一敞篷车回顾。英特尔第12代的升级
在去年推出了全面刷新该系列的 Latitude 9420二合一，今年的Latitude 9430 2-in-1是该系列相对较小的一个进步。最新机型采用了英特尔第12代Alder Lake-U CPU，取代了Latitude 9420二合一上的第11代Tiger Lake-U选项。还有一些其他的升级，我们将在评论中进行介绍，但机箱设计保持不变，因此我们对Latitude 9420 2-in-1的大部分现有评论也适用于Latitude 9430 2-in-1。
我们的测试装置采用酷睿i7-1265U CPU，16GB焊接内存，QHD+ 1600p触摸屏，以及512GB NVMe固态硬盘，可以在网上找到，价格约为2700美元。酷睿i5-1245U SKU也是可用的，但QHD+面板是固定的，用于二合一的形式因素。这一领域的竞争者包括其他14英寸以办公为中心的笔记本电脑，如联想ThinkPad X1 Yoga G7, 惠普EliteBook 840系列,MSI Summit E14 Flip, LG的格拉姆14T90P, 或 华为MateBook 14.

案例
戴尔似乎放弃了Latitude 9420二合一的浅灰色，而在Latitude 9430二合一上采用深色调。除了独特的新颜色之外，没有其他重大的视觉变化。
即使在上市一年后，该设计仍然是14英寸尺寸类别中最小和最薄的一个。然而，它并不轻，因为该机型一般都有更多的功能，包括可选的5G连接。
连接性
与Latitude 9420 2合1相比，端口选项没有变化。如果能看到USB-A 3.2 Gen.2端口而不是Gen.1端口就更好了，但无论如何，没有多少设备能利用Gen.2的速度。
SD卡阅读器
MicroSD读卡器的传输速度是副笔记本上最快的一些。当与华硕ZenBook Flip 14例如，当使用UHS-II卡时，戴尔的文件传输速度大约是2倍。

沟通
5G现在是该系列的一个选项。然而，该功能必须在购买前进行配置，因为否则不包括天线，以阻止用户安装自己的4G或5G模块。

网络摄像头
戴尔将网络摄像头的分辨率从720p提高到1080p，以获得更清晰的画面。惠普在这方面领先一步，因为一些 幽灵 和EliteBook机型已经开始配备500万像素网络摄像头。
维护
底部面板仍然非常容易拆卸。不过，除了固态硬盘和电池之外，没有什么可以维修的，因为WLAN和内存模块是焊接的。
配件和保修
除了交流电适配器和文件之外，盒子里没有任何额外的东西。PN7522W有源笔必须单独购买，价格为80至110美元。
输入设备
键盘和触摸板
与惠普EliteBook或Spectre的键盘相比，我们的Latitude ，键盘略微安静一些，但比较柔软。它的舒适度并不低，因为这主要取决于用户的偏好。然而，惠普机型有一个额外的点，因为它们纳入了一个专用键，用于启动惠普特定的应用程序，如命令中心或myHP。戴尔Latitude ，如果有这样一个键来启动优化器或电源管理器，将是非常有用的。
显示
去年型号上的AU Optronics B140QAN IPS面板已经回归，这意味着用户可以期待Latitude 9420二合一和Latitude 9430二合一之间的相同观看体验。不过，如果至少能看到刷新率更快的新选择，甚至像最新的华硕ZenBook 14或惠普Spectre系列那样采用OLED，那就更好了。特别是非常缓慢的黑白和灰白的响应时间仍然是引人注目的。然而，该面板对于办公室类型的工作负荷来说是非常好的，因为缓慢的响应时间影响不大。
戴尔宣传的sRGB全覆盖，我们可以独立确认。我们不会对一个高端的Latitude 9000系列机型有任何期望。
我们的设备遇到了一个错误，在0-28%的亮度设置范围内，亮度不会改变。亮度会停留在32尼特，直到设置达到29%或更高。戴尔已经意识到这个问题。

这款显示器在开箱后没有被很好地校准，灰度和色彩的平均DeltaE值分别为4和3.38。我们能够用X-Rite色度计将这些平均值降低到0.7和0.41。我们建议安装我们的上述ICM配置文件，以更好地利用面板的全部sRGB覆盖。

在500尼特，显示器比许多其他14英寸的笔记本电脑更亮，以获得更好的户外可视性。联想ThinkPad X1 Yoga G7或 LG Gram 16 2合1.然而，在大多数情况下，眩光仍然是不可避免的，但如果在阴凉处工作，屏幕上的文字和图像仍然清晰和多彩。
业绩
测试条件
在运行以下任何基准测试之前，我们通过Dell Optimizer软件将我们的设备设置为超性能模式。我们喜欢Optimizer有一个设置，将Windows电源配置文件设置与当前Optimizer性能设置同步。例如，如果Optimizer设置为安静模式，那么Windows电源配置文件将自动切换到节电模式。如果优化器设置为超性能模式，那么Windows将自动切换到其同等的性能模式，以此类推。这就解决了多个应用程序的热力设置相互冲突的问题（即Windows设置为节能模式，而优化大师设置为超性能模式）。
令人讨厌的是，优化大师不能被最大化，因此其非常小的窗口尺寸被固定下来。对于拥有如此多的按钮和选项，该应用程序绝对可以从一个更大的用户界面中受益。
处理器
与第11代相比，CPU的收益 酷睿i7-1185G7在去年的Latitude 9420 2-in-1中，特别是在多线程性能方面有显著的提高。与Core i7-1185G7相比，我们的Core i7-1265U的单线程和多线程性能分别提高了20%和55%。该CPU甚至能够与 酷睿i7-1260P尽管酷睿P系列在市场上被称为更快的系列。在刚刚经历了非常令人失望的 酷睿i5-1235U.
性能的可持续性本可以更好。当循环运行CineBench R15 xT时，最初的1572分会稳步下降，并稳定在1230分左右，代表着由于热限制，随着时间的推移，性能下降约20%。

PCMark 10得分一直高于我们在老款Latitude 9420 2-in-1上记录的分数，尽管只是几个百分点。与大多数第11代酷睿i7-1165G7笔记本电脑相比，典型的办公负载，如网页浏览、视频流或轻度编辑，不会感觉快很多。

GPU性能
与其他具有相同集成度的笔记本电脑相比，图形性能与我们期望的差不多。 Iris Xe 96 EUs即使Latitude 是携带较新的第12代英特尔CPU。因此，用户最多只能期待GPU性能同比的边际改善。竞争者 Radeon 680M或GeForce MX450/550能够提供明显比Iris Xe 96 EUs更快的性能。
与Latitude 9420 2合1上的LPDDR4相比，该机型采用了更快的LPDDR5内存，但性能提升不大。

系统噪音
在大多数网络浏览或流媒体条件下，该系统是无声或接近无声的。然而，与我们在Latitude 9420 2-in-1上的体验相比，风扇会更快地开始升温。例如，当运行3DMark 06的第一个90秒基准场景时，Latitude 9420 2-in-1的风扇在整个运行过程中保持沉默。相比之下，Latitude 9430 2-in-1的风扇在35分贝(A)时可以听到，而安静的背景是23.7分贝(A)。
在超性能模式下运行游戏等高要求的负载，会导致风扇的噪音比ThinkPad X1 Yoga G7更响。ThinkPad X1 Yoga G7或LG Gram 14T90P。

压力测试
在运行Prime95时，时钟频率、核心温度和电路板功耗将分别飙升至3.6 GHz、98 C和48 W，只有短短的几秒钟时间。然后，时钟频率将稳步下降，最后稳定在2.4 GHz，以保持更易于管理的板卡功耗和核心温度，分别为24 W和74 C。我们欣赏这次稳定和更可预测的性能，而Latitude 9420二合一的时钟速率和温度在类似条件下会有更大的波动。
运行时的GPU时钟速率和温度 Witcher 3将分别稳定在1097 MHz和66 C，相比之下，Latitude 9420 2-in-1或微星Summit E14 Flip上的时钟频率和温度分别为1200 MHz和73 C。
用电池供电运行限制了性能。在电池上进行的3DMark 11测试将返回物理和图形分数，分别为9711和5679分，而在主电源上则为16290和6231分。

能源管理
消耗功率
在桌面上空转需要3瓦到7瓦，这取决于亮度配置文件和电源设置，这比我们在Latitude 9420二合一上的记录略低。同时，运行Prime95消耗约62瓦，而去年的型号只有32瓦，当CPU受到压力时，功耗增加高达94%。从酷睿i7-1185G7跳到酷睿i7-1265U时，多线程性能提高50%。 酷睿i7-1265U在这方面并不是免费的。
与大多数其他笔记本电脑不同，戴尔在结账时提供了三种交流适配器选项。90 W选项对于为CPU提供更多的电力以获得更高的Turbo Boost时钟速率，从而获得更高的性能非常有用。然而，我们的压力测试表明，无论如何，系统不能长时间保持非常高的Turbo Boost时钟速率，因此90W交流适配器的任何性能提升都是短暂的。例如，在小型（约6.7 x 5.5 x 2.2厘米）60瓦交流适配器上运行Prime95时，功耗将稳定在61瓦。用较大的（约13 x 6.5 x 2.3厘米）90瓦交流电适配器重复这一测试，会导致消耗量在测试开始时飙升至91.6瓦，然后最终下降并在大约90秒后稳定在51瓦，正如我们下面的图表所示。如果你打算运行高要求的程序，90W适配器仍然是一个很好的选择，因为CPU性能的短暂爆发可以在加载应用程序或处理图像时节省时间。

Pros
Cons
结论 - 同样的包装，新的名称
我们喜欢的一切 Latitude 9420二合一Latitude 9430 2-in-1全面回归，因为较新的型号主要是处理器更新。CPU带来了更快的性能，尽管功耗水平更高，这与我们在其他Alder Lake笔记本电脑上观察到的情况基本一致。如果更快的CPU、5G选项或200万像素网络摄像头对你的日常工作负荷没有吸引力，那么Latitude 9420 2合1可以提供基本相同的体验，而且价格更低。
Latitude 9430二合一是为那些知道他们可以利用英特尔第12代CPU的强大用户准备的。否则，物理上相同的Latitude 9420二合一产品已经足以满足目标办公用户的需求。
需要记住的一些小烦恼包括不支持80毫米M.2固态硬盘，如果配置时没有广域网支持，则不支持广域网天线。CPU Turbo Boost是有限的，而如果用电池供电运行，性能会降低。另外，令人遗憾的是，主动式手写笔是单独出售的，而竞争对手如联想ThinkPad X1 Yoga G7等竞争对手则在每次购买时都包括手写笔。大多数笔记本电脑都支持更常见的80毫米固态硬盘，这可能会使戴尔的固态硬盘更换更加困难。同时，惠普EliteBook 1040带有一个更明亮的触摸屏，尽管分辨率较低，为1200p。也许戴尔可以通过500万像素网络摄像头和高刷新率的OLED显示屏来改善视觉体验，使明年的最终机型更具吸引力。
价格和可用性
戴尔目前正在运送Latitude 9430蚌壳和2合1。我们的具体配置是Core i7-1265U和16GB内存，售价约为2800美元。
