Magyar英特尔酷睿i5-1345U性能首次亮相：戴尔Latitude 3440笔记本电脑评测
2023年的Latitude 3440（不要与2013年的同名型号混淆）。 2013年的同名机型)是戴尔的一款预算型14英寸商务笔记本电脑。它是价格较高的中端产品的一个钱包友好型替代品 Latitude 5420和高端 Latitude 7420或旗舰机 Latitude 9430.
我们审查的配置是一个中间SKU，配备第13代猛禽湖-U酷睿i5-1345U vPro CPU，16GB内存，512GB NVMe SSD，以及1080p 45% NTSC显示屏，价格约为1100美元。其他选项有较小的酷睿i3-1315U，较高端的酷睿i7-1355U，或更深72%NTSC颜色的1080p显示屏。戴尔计划在不久的将来提供一个独立的GeForce MX550图形选项。
Latitude 3440的替代品包括其他预算办公笔记本电脑，如 Acer Aspire Vero, 惠普ProBook 440 G9, 联想ThinkPad E14, 或华硕ExpertBook L1.

案例 - 仅仅是基础知识
底座由PCR塑料组成，这在预算系列中是可以预期的。尽管如此，刚性还是相当好的，尽管在试图扭转它时，底座会有轻微的吱吱声。按压外盖的中心会导致比我们希望的更多的翘曲。
连接性 - 没有Thunderbolt或HDMI 2.0

维护
底部面板只需一把飞利浦螺丝刀就可以轻松拆卸。M.2固态硬盘、2个SODIMM、电池和WLAN模块都是可拆卸的。
配件和保修
零售包装盒包括一个专有的桶状交流适配器或USB-C交流适配器。我们建议配置前者，因为它可以腾出笔记本电脑上的一个USB-C端口用于其他设备和配件。
如果在美国购买，标准的一年有限保修期适用。
输入设备 - 舒适的键盘与笨重的点击板
键盘
对于一台经济型笔记本电脑来说，打字体验出奇地舒适。包括空格键和回车键在内的按键反馈感觉均匀而牢固。
键盘的两级白色背光是一个可选的附加装置。
触摸板
点击板（11.5 x 6.8厘米）比起其他品牌的点击板略大。Acer Aspire Vero(10.5 x 6.5厘米)或 华硕ExpertBook L1(10.5 x 6.2厘米)。即使以较慢的速度滑行，牵引力也非常平稳。然而，我们设备上的点击板对于多点触摸输入（如双指滚动）是不可靠的。
显示器--明智地选择你的IPS颜色
我们的测试设备配备了低端的京东方NE140FH IPS面板，只提供60%的sRGB颜色和近300尼特的最大亮度。在电池供电的情况下，最大亮度上限降低到只有265尼特，这影响了显示器在户外的可视性。如果更深、更准确的颜色对你的工作负荷很重要，那么我们建议升级到72%的NTSC选项。
尽管色彩再现有限，但对比度相当好，约为1500：1。某些SKU可能带有768p的TN面板，我们建议避免使用。

色温偏冷，这是经济型显示器的典型特征。用我们的X-Rite色度计进行适当的校准可以解决这个缺点，但由于上述有限的色彩空间，高饱和度的色彩仍然不准确。
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 | ||
|---|---|---|
| 29.8 ms ... rise ↗ and fall ↘ combined | ↗ 17.1 ms rise |  |
| ↘ 12.7 ms fall | ||
| The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 77 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.5 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 35.3 ms ... rise ↗ and fall ↘ combined | ↗ 16.3 ms rise |  |

| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 43 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (33.7 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 17903 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
性能--第13代酷睿i5-1345U比第12代系列的性能提升很少
测试条件
在运行下面的性能基准测试之前，我们通过戴尔优化器将我们的设备设置为超性能模式。戴尔的电源配置文件与Windows的电源配置文件方便地同步，与大多数其他笔记本电脑不同。
处理器
芯片 酷睿i5-1345U在性能方面是一个混合包。当循环运行CineBench R15 xT时，性能会随着时间的推移而下降26%，这比华硕或联想的竞争子笔记本的性能要高，如下图所示。老款的酷睿i7-1255U甚至是 酷睿i5-1235U仍然可以超越酷睿i5-1345U。我们希望其他笔记本电脑型号能够以比Latitude 3440 上更高的可持续时钟速率运行酷睿i5-1345U。
升级到酷睿i7-1355U预计可将CPU性能提高30%至40%，这是基于我们使用联想瑜伽7 16IRL8.然而，有可能在Latitude 3440，就像我们在i5-1345U配置上遇到的情况一样，它可能会更严重地节流。

GPU性能--集成Iris Xe
图形性能在同类产品中是不错的，其结果与我们数据库中配备相同集成的其他笔记本电脑相当。 Iris Xe 80 EUsGPU。升级到配备Iris Xe 96 EUs的酷睿i7-1355U配置，预计可将图形性能提高30-45%，而即将推出的 GeForce MX550选项可以将性能提高2倍。尽管如此，集成的Iris Xe系列在三年多的时间里没有明显的改进。
我们建议避免使用单通道8GB内存配置，否则集成图形性能会进一步下降。

排放
系统噪音 - 浏览或流媒体时保持安静
在运行视频、浏览器或电子表格等普通办公任务时，系统风扇通常是惰性的。即使在引入更高的负载时，风扇也会在相对长的时间内保持安静。例如，直到第一个90秒的3DMark 06基准测试场景接近尾声时，风扇才开始升温到更容易听到的37分贝（A）。像游戏这样的极端负载会引起高达40dB(A)的风扇噪音，这比宏碁Aspire Vero和戴尔Aspire 7420的噪音都小。 戴尔Latitude 7420.

压力测试
在启动Prime95压力时，CPU将提升到3.4 GHz、32 W和93 C，时间只有几秒钟。此后，它将稳步下降到只有2.0 GHz、18 W和80 C，以保持温度的控制。该处理器有限的Turbo Boost潜力反映在上面提到的不断下降的CineBench分数和下面一节中的功耗结果。
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9054和4919分，而在主电源上则为12272和5214分。

WLAN的运行时间与竞争者相仿。 竞争者ThinkPad E14 G4 而比惠普ProBook 440 G9要长得多，后者配备的是一个较小的42Wh电池。
使用附带的USB-C适配器从空电到满电需要2个多小时。

Pros
+ 价格相对低廉
+ 舒适的键盘
+ 易于维修
+ 良好的电池寿命
Cons
- 与第12代Alder Lake-U相比，没有重大的性能优势
- 点击板在检测多点触控输入时有问题
- 只有一个USB-C接口
- 没有SD卡读卡器
结论 - 廉价的、不费力气的办公笔记本电脑
对于那些不需要花哨的二合一功能、OLED触摸屏、光滑的金属设计或酷睿H系列性能的工人来说，这款笔记本电脑本身成功地成为一个基本的办公伴侣。它可与 ProBook 440 G9在大多数方面与ProBook 440 G9相当，但在电池寿命方面，我们的戴尔设备更胜一筹。然而，我们建议检查点击板的多点触摸性能，因为我们测试设备上的点击板在识别双指滚动和缩放方面有问题。
Latitude 3440既不令人印象深刻也不令人失望。相反，它是一款不折不扣的商务笔记本电脑，拥有恰到好处的可选配件和口哨，可以满足大多数办公任务。
它的 酷睿i5-1345U处理器本身有点让人失望。它不仅没有提供比老款酷睿i5-1235U更多的性能优势，而且还需要同样多的电力，但每瓦性能却没有显著提高。因此，该处理器感觉像是去年酷睿i5 U系列选项的重塑。你必须升级到更昂贵的酷睿i7-1355U选项，才能获得任何实际的性能优势。
价格和可用性
戴尔现在正在运送 Latitude 3440，基本的酷睿i3配置起价为769美元，如果完全配置酷睿i7-1355U，则为1319美元。
