Magyar适用于商业用户的XPS敞篷车：戴尔Latitude 9440 2合1评论
虽然 Latitude 9420二合一和 Latitude 9430二合一 分享相同的机箱设计，今年的Latitude 9440 2-in-1从顶部到底部是一个完整的更新。 在2023年国际消费电子展期间发布的Latitude 9440 2-in-1融合了XPS 13 Plus的设计特点。 XPS 13 Plus的设计特点，以获得更有吸引力的外观。内部结构也从英特尔第12代Alder Lake-U升级到第13代Raptor Lake-U处理器选项。
我们审查的单位是一个高端配置，配备酷睿i7-1365U vPro CPU，32GB快速LPDDR5x-6400焊接内存，以及1TB NVMe固态硬盘，价格约为2900美元。较小的SKU可从Core i5-1335U开始，价格为1900美元，但所有选项都配备相同的2560 x 1600 IPS触摸屏和集成Iris Xe图形。
Latitude 9440 2-in-1的替代品包括其他高端商务副笔记本，如联想ThinkPad X1 Yoga G8,华硕ExpertBook B7 Flip，或 惠普EliteBook系列.

案例--看起来更好，同样强大
当处于关闭状态时，Latitude 9440 2-in-1看起来与大多数其他Latitude 型号相似。然而，当打开时，变化和XPS的灵感变得很明显。零点阵键盘直接来自XPS 13 Plus，而点击板现在有明确的边缘，这是对XPS 13 Plus上 "隐形 "点击板的一个主要批评。同时，XPS上的一排触摸感应按钮已经被重新设计，并沿着点击板的上半部分重新定位。键盘两侧的向上发射的扬声器是从去年的Latitude 9430二合一产品中延续下来的。
值得庆幸的是，所有的物理变化都没有影响到刚性或制造质量。试图扭转底座、盖子或键盘中心将导致只是最小的翘曲，与Latitude 9430 2-in-1或 HP Spectre x360 13.5.它实际上感觉比13英寸的XPS 13 Plus更强，也许是由于其较大的14英寸外形尺寸。
新的2023型号比即将推出的2022设计更厚、更重，尽管有所有的物理变化。虽然增加的幅度很小，但它们足以使该系统比竞争机型如ThinkPad X1 Yoga G8或ExpertBook B7 Flip各重约200克。
连接性 - 希望你喜欢USB-C
端口选项可以说比去年的Latitude 9430二合一产品更差。老款产品集成了USB-A、MicroSD甚至HDMI，而Latitude 9440二合一产品则放弃了所有这些接口，只支持USB-C，没有其他接口。我们理解USB-C的前瞻性和多功能性，但它仍然是一个难点，特别是当竞争对手如华硕ExpertBook B7 Flip或联想ThinkPad X1 Yoga G8仍然整合了更多的端口，以减少对电子狗的依赖。
沟通
英特尔AX211是Wi-Fi 6E和蓝牙5.2连接的标准配置。当与华硕AXE11000 6GHz网络配对时，我们经历了一致的传输率，没有任何问题。

网络摄像头
200万像素的网络摄像头没有从去年的设计中升级。红外线和钥匙激活的快门是标准配置，分别是为了你好和隐私。
维护
底部面板只需用一把十字螺丝刀就可以轻松拆卸。然而，除了M.2固态硬盘和M.2广域网插槽之外，并没有太多可升级的地方。不幸的是，如果不配置广域网卡，就不包括广域网天线。
配件和保修
零售盒中有一个小型的USB-C转USB-A适配器，以弥补有限的端口选择。标准的一年有限制造商保修期，而不是某些Precision 型号可能提供的三年保修期。
输入设备--看起来和感觉上都像XPS 13 Plus
键盘
从视觉上看，零点阵键盘有助于将该机型与其他笔记本电脑区分开来，它也允许相对较大的键帽尺寸。另一方面，打字体验并没有明显改善，因为键程和反馈仍分别较浅和较软。惠普EliteBook或LG Gram上的键盘LG Gram例如，惠普EliteBook或LG Gram上的键盘更结实、更有深度。由于按键反馈较软，至少咔嚓声相对安静。
触摸板
点击板比去年的设计大（13.5 x 9厘米对11.5 x 7.2厘米），也比其他大多数14英寸笔记本电脑大。牵引力非常平稳，以较慢的速度移动时几乎感觉到滑溜溜的。不幸的是，在点击板上按下时的反馈是非常松散的，有一种不令人满意的点击。由于反馈不佳，像拖放这样的简单动作很难执行。对于典型的游戏笔记本来说，这只是一个小小的抱怨，但我们发现这个缺点对于像Latitude 这样以商业为中心的次笔记本来说是比较严重的。
9440二合一笔记本特有的一个新功能是触觉协作触摸板，它基本上是点击板上的一组四个触摸感应按钮，用于切换摄像头、麦克风、屏幕共享和聊天窗口。然而，主要问题是，这些命令只适用于Zoom电话--依赖微软团队、Discord、谷歌Hangouts或其他会议软件的商业用户完全不走运。
显示屏 - 与Latitude 9420 2合1相同
戴尔为其14英寸Latitude 系列部署相同的AU Optronics B140QAN IPS面板已有数年。因此，Latitude 9440二合一产品使用的面板与较早的 Latitude 9420二合一因此，在观看体验方面没有重大升级。这不一定是坏事，因为友达B140QAN是一款适用于办公室类型工作负荷的优秀面板，但如果能看到更高的刷新率或更深的P3色彩选项，以更好地将Latitude 9440二合一产品与前代产品区分开来，那就更好了。

该面板开箱即被很好地校准，平均灰度和彩色DeltaE值分别只有1.6和2.33。我们自己进一步校准它将导致更低的DeltaE值，只有1.5和0.93。用户可以应用我们上面的校准过的ICM配置文件，但在这种情况下并不是绝对必要。

测试条件
在运行下面的基准测试之前，我们将戴尔优化器设置为超性能模式。方便的是，戴尔的电源配置文件可以与Windows的电源配置文件同步，这与大多数其他笔记本电脑不同。
处理器
芯片 酷睿i7-1365U可能比 酷睿i7-1265U去年的Latitude ，但这两颗CPU的性能几乎相同。甚至它们之间的Turbo Boost和节流行为也相似，下面我们的CineBench R15 xT循环结果就是例证。令人遗憾的是，戴尔没有提供任何Core-P选项，而根据我们对2023框架笔记本电脑的体验，Core-P可以将多线程性能提高40%。 2023框架笔记本电脑.
降级到 酷睿i5-1345U vPro或 i5-1335U从我们的酷睿i7-1365U降级到酷睿i5-1345U vPro或i5-1335U，预计会使多线程性能降低约20%。

存储设备
我们的测试设备配备了一个中档的1TB 三星PM9B1PCIe4 x4 NVMe固态硬盘，其读写速度分别高达3700 MB/s和3000 MB/s。然而，性能在大量使用一分钟后就会变慢。例如，运行DiskSpd 8分钟后，测试开始时的传输率将高达3700 MB/s，然后随着时间的推移稳步下降到2600 MB/s，如下图所示。尽管如此，对于一台搭载Core U的笔记本电脑来说，性能仍然是足够的。
请记住，这款笔记本电脑支持较短的M.2 2242外形尺寸，而不是较长和更常见的2280，以保持最低的重量。

GPU性能--Iris Xe显示了它的年龄
由于英特尔尚未更新其集成的Iris Xe系列，图形性能至少在2到3年内一直处于平缓状态。 Iris Xe系列.任何一个人如果从 UHD Graphics仍将看到性能的显著提升，但希望得到不同东西的用户可能会感到失望。替代品如惠普Dragonfly Pro或联想ThinkPad P14s配备了更快的 AMD Radeon 680M选项。
降级到 Iris Xe 80 EUs从我们的Iris Xe 96 EUs降至低端Core i5 SKU上的Iris Xe 80 EU，预计将影响图形性能约15%至30%。

系统噪音
戴尔将冷却解决方案从去年的Latitude 9430二合一产品上的一个~45毫米的风扇升级到今年的两个较小的~30毫米风扇。有趣的是，在运行3DMark 06时，风扇的噪音仍然大致相同，约为36 dB(A)，而当CPU处于100%的利用率时，则高达44 dB(A)。然而，变化的是风扇的音调，现在更低了，因此不那么明显或分散注意力。如下图所示，较低的音调体现在较宽的风扇噪音曲线和9430二合一的较陡峭的曲线上。

温度
由于内部有对称的冷却解决方案，表面温度曲线大部分是对称的。即便如此，键盘中心的热点也不比老款的温度高。 Latitude 9430二合一在运行高要求的负载时，温度约为36至38摄氏度，而竞争者ThinkPad X1 Yoga G8的温度略高。然而，运行浏览或视频流时的平均温度明显比去年的机型高，但不是令人不舒服的水平。

压力测试
在运行Prime95压力时，CPU将提升到3.5 GHz，100 C和45 W。然而，由于核心温度过高，时钟频率和主板功耗将迅速稳定地下降到2.8 GHz和30 W，以保持90 C的稍冷温度。 ThinkPad X1 Yoga G8也会导致类似的高核心温度。像我们的Latitude ，采用Core-U CPU的副笔记本预计不会长时间保持高Turbo Boost时钟速率。
用电池供电运行并不会限制性能。在电池上进行的3DMark 11测试的分数与我们在主电源上的分数相差不到1%。

能源管理--对电池寿命没有改善
消耗功率
尽管它们之间的性能数字几乎相同，但系统的要求比去年的机型略高。这有可能解释下面一节中电池寿命较短的原因。
在运行Prime95时，我们能够从小型（约11.2 x 5 x 2.7厘米）65瓦的交流适配器中记录到68瓦的临时最大消耗。由于散热限制，消耗量会随着时间的推移而下降，这也是大多数酷睿U系列笔记本电脑的预期。AMD Zen 3或较新的笔记本电脑，如 蜻蜓Pro能够提供比大多数（如果不是所有的第13代酷睿U供电的解决方案）更高的每瓦性能。

电池寿命
电池容量与去年的Latitude 9430二合一产品保持一致。然而，总体运行时间始终较短。我们的真实世界WLAN测试将测试持续约9小时，而Latitude 9430 2合1的测试时间超过12小时。即便如此，电池寿命仍然很好，足以满足全天的使用。

Pros
Cons
结论--Latitude 9430二合一产品更吸引人
Latitude 9440二合一产品从外观上看非常出色。然而，在视觉上与去年的 Latitude 9430 2-in-1带来了更多的缺点，买家可能要小心了。
首先，新机型比上一机型更厚、更重。如果更大的尺寸意味着更多的功能和端口，这并不一定是一个缺点，但不幸的是，情况并非如此。相反，9440二合一产品的端口选项较少，电池容量与9430二合一产品相同。
其次，点击板更难使用，特别是在涉及拖放操作时。此外，令人费解的是，为什么Zoom专用的控件不能用于任何其他会议软件，为什么它们不能像一些惠普EliteBook机型上的可编程键那样进行定制？ 一些惠普EliteBook机型上的可编程键.
第三，CPU从12代酷睿U升级到13代酷睿U，在性能和电池寿命方面最多只能提供最小的好处。当与三年前的1600p触摸屏结合在一起时，用户体验是否真的比去年已经很出色的Latitude 9430二合一产品更好，这是可以争论的。
需要Latitude 9440二合一的用户必须真正重视外部设计选择和Zoom特有的 "触觉协作 "热键。否则，较早的Latitude 9430二合一产品提供了更多的端口，更轻更薄的机身，更可靠的点击板，以及基本上相同的性能和观看体验，而花费却更少。我们希望在未来看到更多可配置的选项，以更好地吸引买家，如1000尼特面板、Core-P选项、更高分辨率的网络摄像头，也许还有一个更传统的带有专用鼠标按钮的点击板。
不管是好是坏，戴尔Latitude 9440二合一产品牺牲了一些可用性方面，而选择了更酷的外观设计。
价格和可用性
戴尔现在正在运送 Latitude 9440二合一产品，基本的酷睿i5配置起价1920美元，如果配置酷睿i7-1365U，则起价2800美元或更高。
