戴尔Inspiron 14 Plus 7420笔记本电脑评论。适用于预算有限的电力用户
戴尔为2022年推出了三种独立的14英寸Inspiron 14 7420机型:标准Inspiron 14 7420、Inspiron 14 7420二合一和Inspiron 14 7420 Plus。这次审查的重点是Plus型号,它带有更快的酷睿H系列处理器和独立的NvidiaGeForce RTX图形,专为对通常的酷睿U系列超极本不满意的电力用户设计。
我们的具体审查单位配备了Alder Lake-H Core i7-12700H CPU和GeForce RTX 3050 GPU,零售价约为1400美元。其他SKU配备Core i5-12500H、RTX 3050 Ti或集成显卡,并计划配备较小的54Wh电池,但所有配置都配备相同的2K 2240 x 1400分辨率面板。
竞争对手包括其他高性能14英寸笔记本电脑,如华硕VivoBook Pro 14 ,惠普Pavilion 14 Plus , 申科Vision 14 ,惠普Envy 14 ,或联想IdeaPad 5 Pro 14 。Razer Blade 14 和Asus Zephyrus G14 也可以考虑作为替代品,但它们的价格明显更高。

箱子 - 一个微型的Inspiron 16 7620
该机箱可以说是一个较小版本的 Inspiron 16 7620 Plus因为它们都采用了相同的视觉设计语言。金属底盘和点击板及掌托上的一层Mylar所使用的材料也因此与较大的Inspiron相似。它从上到下都是光滑的磨砂感觉,几乎模仿了XPS 15的光滑金属外盖。 XPS 15.
骨架最薄弱的方面也许是盖子,因为它很容易扭曲。扭动底座时可以听到轻微的吱吱声,对键盘中心施加压力也会使其表面轻微翘起。尽管该机型的售价几乎与戴尔XPS 15一样,但不要指望它能像戴尔XPS 15那样坚固。
人们可能期望Inspiron 14 Plus 7620比Inspiron 14 7620二合一机型更大、更重,但实际情况并非如此。它的占地面积与二合一版本相同,尽管里面的硬件功能明显更强大,但也只是略微厚重一些。尽管如此,它仍然比大多数其他14英寸笔记本电脑(如惠普Envy 14)更重、更大。华硕Zenbook 14X或Schenker Vision 14等其他14英寸笔记本电脑相比,更重更大,这些笔记本电脑也都配备了独立的Nvidia显卡。
连接性 - 支持Thunderbolt 4
端口选项与Inspiron 16 Plus 7620相同,尽管全尺寸的SD读卡器被换成了一个较小的microSD。我们很欣赏对Thunderbolt 4的支持,因为竞争者都没有 惠普Pavilion Plus 14和华硕Vivobook Pro 14 OLED都不支持Thunderbolt,尽管它们有USB-C接口。
SD卡阅读器
集成的弹簧式MicroSD读卡器的传输速度很慢,就像我们在Inspiron 14 7420二合一上观察到的那样。将1GB的图片从我们的UHS-II测试卡移动到桌面需要大约45秒。

沟通
英特尔AX211是Wi-Fi 6E和蓝牙5.2连接的标准配置。虽然我们在与6GHz网络配对时没有遇到任何问题,但如下图所示,发射率会比接收率略微不稳定。

网络摄像头
200万像素的网络摄像头提供了与标准Inspiron 14 7420二合一产品上的200万像素网络摄像头类似的图像质量。物理隐私快门是标准配置,不支持Windows Hello和IR。
维护
底部面板用飞利浦螺丝刀和锋利的塑料边缘相当容易弹出。一旦进入,用户可以维修电池、1个M.2 2280存储插槽、1个DDR5 SODIMM插槽和M.2 WLAN模块。请注意,所有SKU上都焊接了8GB的内存,这意味着用户可以只添加一个模块,最大的内存容量为40GB。
配件和保修
除了交流电适配器和文件外,盒子里没有其他额外的东西。如果在美国购买,通常有一年的有限保修。
输入设备--来过这里,见过那里
键盘和触摸板
打字的体验与Inspiron 16 Plus 7620相同。 键盘输入体验与Inspiron 16 Plus 7620相同。,Inspiron 16 7620 2合1或 Inspiron 14 7420 2-in-1因为这四种机型都有相同的键盘按键和Mylar点击板。即使是主键和副键的符号以及点击板的尺寸(11.5 x 8厘米)在各型号之间也是相同的,而不考虑任何屏幕尺寸差异。简而言之,除了感觉有点太浅的空格键之外,按键有足够的反馈和适度的咔哒声。同样,点击板的表面对于标准的光标控制来说是可靠的,而其集成的按键在拖放时则过于柔软和有弹性。
显示器 - 全sRGB覆盖和60赫兹
虽然其他14英寸笔记本电脑通常以1200p、1800p或2160p的原生分辨率为目标,但Inspiron 14 Plus 7420标配了相对不常见的2.2K或2240 x 1400面板。其他核心属性都很扎实,包括全sRGB覆盖率、约1000:1的对比度,以及对其尺寸级别来说不错的响应时间。令人遗憾的是,OLED或光面选项无法进一步提高色彩或锐度。

该显示器在出厂时没有经过校准,因此它的颜色并不像它们可能的那样准确。尤其是色温,与sRGB标准的6500目标值相比,6000左右的色温过于温暖。用我们的X-Rite色度计进行适当的校准后,平均灰度和彩色DeltaE值将从3.6和2.23分别提高到0.8和0.63。我们建议进行终端用户校准,以充分利用面板100%的sRGB覆盖率。

户外能见度不高,因为显示屏在最大设置下平均只有300尼特。如果在户外,你要尽可能在阴凉处工作,否则屏幕在较亮的环境光线下会被冲淡。微星微星Summit E14携带一个明显更亮的屏幕,同时仍然提供独立的GPU选项,与之相比。
性能--14英寸的增压机
测试条件
在运行以下任何基准测试之前,我们通过 "我的戴尔 "软件将我们的设备设置为超性能模式。建议业主熟悉 "我的戴尔",因为它是保修支持、电池充电行为、系统性能等方面的门户,如下文截图所示。
支持标准Optimus,在集成和独立的GeForce RTX 3050 GPU之间切换。不支持高级Optimus、MUX和WhisperMode。
处理器
CPU的性能可以从玻璃半满或玻璃半空的角度进行分析。从悲观的角度来看,45W的 酷睿i7-12700H有点令人失望,因为它的多线程性能比其他配备相同处理器的笔记本电脑慢10%左右。从乐观的角度来看,戴尔的速度明显快于其他大多数14英寸笔记本电脑,其中15W、25W或35W的CPU更为常见。这是你能得到的配备酷睿i7-12700H的小型笔记本电脑之一,但反过来说,与配备相同处理器选项的大型笔记本电脑相比,其Turbo Boost性能随之受到更多限制。毕竟,酷睿i7-12700H也经常出现在成熟的游戏笔记本上。例如,采用相同CPU的16英寸联想Legion Slim 7,其性能比我们的Inspiron 14 Plus快30%。
我们的CPU的Turbo Boost性能有限,可以通过循环运行CineBench R15 xT来证明。如下图所示,我们最初的2410分,到第三或第四个循环时将下降21%,代表着明显的性能下降。

GPU性能--对于尺寸和价格而言是快速的
图形性能是我们所期望的,相对于其他具有相同性能的笔记本电脑而言 GeForce RTX 3050GPU。事实上,其结果与Schenker Vision 14或Schenker Flow Z13上的RTX 3050 Ti相当。华硕ROG Flow Z13.戴尔可能会在不久的将来推出带有RTX 3050 Ti的SKU,但我们不推荐它,因为它可能最多只是比我们的基本RTX 3050 SKU略快。
从老得多的GTX 1650 Ti Max-Q 升级的用户将看到约50%的显著改善。
请记住,如果在戴尔优化模式而不是戴尔超性能模式下运行,图形性能会降低。在优化模式下进行的Fire Strike 测试将返回10966分的图形分数,而在超性能模式下则为12125分。

系统噪音
该系统中的双风扇对高负载很敏感。例如,当启动3DMark 06时,风扇噪音会迅速增加,然后在第一个基准场景结束时稳定在47 dB(A)左右,而Schenker Vision 14的噪音为43 dB(A),Schenker Vision 14的噪音为35 dB(A)。 HP Envy 14每台电脑都有独立的GeForce 图形。
在超性能模式下运行游戏会导致风扇噪音达到近52分贝(A),这与许多具有更快的图形的专用游戏笔记本电脑相当。如果在戴尔优化模式下进行游戏,风扇噪音将降至48分贝(A),但如上所述,这将导致图形性能的小幅削减。因此,如果用户希望榨取GeForce GPU的全部50W功率包络,他们必须忍受风扇的最大转速。
值得庆幸的是,在浏览网页或视频流等比较平凡的任务中,风扇是相当安静的,只有26.5分贝(A),而背景是23.2分贝(A)。只有当更高的负载被引入时,它们才会开始快速上升。

压力测试
运行Prime95对CPU施加压力会导致时钟频率、温度和电路板功耗分别飙升至3.5 GHz、100 C和80 W,持续约10秒左右。此后,时钟频率、温度和电路板功耗将稳步下降,然后分别稳定在1.9 GHz、80 C和38 W,以保持温度的控制。性能的下降是比较陡峭的,因为 惠普Pavilion Plus 14在接受同样的测试时,相同的CPU能够保持更快的2.2至2.9GHz的范围。
运行 Witcher 3显示GeForce GPU稳定在1590 MHz、74 C和50 W。相比之下,更大的Inspiron 16 Plus中的RTX 3050 Ti将稳定在1627 MHz、84 C和63 W。核心温度高是毫不奇怪的,因为这是少数同时配备Core H系列CPU和GeForce RTX GPU的14英寸笔记本电脑之一。将电源配置文件从 "超性能 "改为 "优化",可以将GPU的功耗降至约45W或更低。
用电池运行限制了性能。在电池上进行的Fire Strike ,物理学和图形学的分数分别为9493和7637分,而在电源上则为26940和12125分。

能源管理--苛刻的小机器
消耗功率
在省电模式下,如果在最低亮度设置下,功耗在6W之间,如果在最大设置下,功耗在10W之间。在Nvidia GPU激活的情况下,将电源配置文件更改为超性能模式,将空闲功耗提高到20瓦,这大约是大多数由U系列CPU驱动的较慢的14英寸笔记本电脑的两倍。
游戏需要96瓦至106瓦,而传统的U系列处理器只需要40瓦或50瓦。众所周知,英特尔第12代H系列在已经要求很高的独立GPU的基础上要求非常高。因此,难怪Inspiron 14 Plus比一般的14英寸笔记本电脑运行时声音更大、温度更高。
当同时运行Prime95和FurMark时,我们能够从中等大小(约15.3 x 7.5 x 2.6厘米)的130瓦交流适配器中记录到137瓦的最大消耗。正如我们下面的截图所示,消耗量往往在110瓦和137瓦之间循环。如果运行这样的负荷,预计充电速度会比较慢。

Pros

结论--大尺寸的性能,大尺寸的重量
如果你想在你的下一个14英寸笔记本电脑上最大限度地提高CPU和GPU性能,那么可以考虑价格更高的 雷蛇刀片14或 华硕Zephyrus G14.如果你正在寻找一款轻薄的14英寸超极本,那么 华硕Zenbook 14或 LG Gram 14可能是更好的选择。然而,对于两方面的最佳选择,戴尔Inspiron 14 Plus 7420在极端性能和便携性之间游刃有余,同时将价格保持在合理水平。经常旅行的人如果对性能的依赖超过了酷睿U系列和集成显卡系列所能提供的,会发现戴尔是一个坚实的解决方案。
将如此强大的动力装入14英寸的机箱,会带来通常的缺点:温度较高,风扇噪音较大,重量较重,以及比14英寸类别中的大多数其他笔记本电脑的功耗更高。在这四个缺点中,我们认为重量可以得到最大的改善,因为竞争者的华硕Vivobook Pro 14配备了AMD H系列CPU和相同的GeForce RTX 3050 GPU,而重量却轻了几百克。风扇至少在较低的处理负荷中保持安静,因此只有在运行要求较高的应用程序时才会有声音。
Inspiron 14 Plus 7420可能很重,但它能以比一般超极本更快的速度完成工作。
其他缺点包括海绵状的点击板和灵活的盖子。对于这么重的14英寸笔记本电脑,如果有一个更坚硬的盖子就更好了。与这个价格范围内的大多数14英寸笔记本电脑相比,其性能优势是该系统的主要亮点。
价格和可用性
Inspiron 14 Plus 7420外壳现已在亚马逊上发货。 和Newegg 价格分别为1300美元和1400美元。但是,配置目前只限于集成显卡。我们建议直接从戴尔购买https://www.dell.com/en-us/shop/laptops/new-inspiron-14-plus/spd/inspiron-14-7420-laptop如果你想要GeForce RTX 3050 SKU。
