戴尔Latitude 7450 二合一笔记本电脑评测:多功能商务可折叠笔记本电脑,在大多数方面都表现出色

精心策划的商业行动。

戴尔Latitude 7450 2 合 1 机型采用英特尔酷睿至强 7 165U vPro 处理器,性能出色,同时还为商务人士的移动办公量身定制了一系列强大的功能。戴尔甚至还提供了一系列强大的工具,让 IT 管理人员满意而归。不过,与上一代产品相比,戴尔的改进是循序渐进的,它的竞争对手,尤其是新的联想 ThinkPad 系列,也提供了同样引人注目的选择。

评价:循序渐进,但值得欢迎的换代升级,做到了很多正确的事情

戴尔Latitude 7450 2 合 1 是一款多功能、高效的可转换设备,适合移动办公的商务用户使用。铝制结构坚固耐用,没有弯曲和尖角,重量也恰到好处。

尽管设计纤薄,Latitude 7450 2-in-1 还是提供了一套可靠的连接选项,Wi-Fi 7 WLAN 卡的吞吐量令人印象深刻。键盘和触摸板不会妨碍令人满意的输入体验。

60 Hz FHD+ IPS 触摸屏适合典型的商务人士使用,亮度尚可,sRGB 全色覆盖,无 PWM。Latitude 7450 2 合 1 的整体性能符合英特尔酷睿至尊 7 165U 笔记本电脑的预期,戴尔的设计能够确保低辐射和低功耗。

不过,也有几个方面值得关注。网络摄像头的质量尚可,但考虑到竞争对手已经开始过渡到 500 万像素或更高的传感器,当然还可以做得更好。

该设备的初始性能相当差,尤其是在单核测试中,需要随后更新 BIOS 才能改善。不过,在多核负载情况下,CPU 仍难以维持 44 W 的 PL2。如果你打算运行多线程应用,这一点需要注意。

您需要全面评估自己的业务需求,并据此进行配置,因为除了更换唯一的固态硬盘外,几乎没有任何内部更改的余地。

虽然Latitude 7450 2 合 1 确实有很多优点,但并没有太多令人信服的理由值得立即从Latitude 7440 升级。

Pros

+ 坚固的全金属结构
+ 快速 WLAN 网络连接和良好的端口选择
+ 色彩鲜艳的 IPS 面板,全 sRGB 覆盖,无 PWM
+ 表面热量和风扇噪音低
+ 低闲置功耗

Cons

- 显示响应时间慢
- Core Ultra 7 165U 无法长时间支持 44 W PL2
- 几乎没有元件升级空间
- FHD 网络摄像头质量尚可
- 与上一代产品相比,升级幅度不大

价格和供应情况

戴尔Latitude 7450 2-in-1 配备 Intel Core Ultra 7 165U vPro,目前在美国戴尔公司的售价为 229 美元。美国亚马逊提供 256 GB SSD 版本,售价为 1,845 美元

戴尔印度网站显示,测试配置的售价为 4,22,011 ₹,高出 2.5 倍。Latitude 7450 2-in-1 也已在印度亚马逊上市,但目前供货情况不明。

机箱和连接性高级全铝机身,I/O 接口齐全

Latitude 7450 2 合 1 采用了时尚的全铝机身,表面为泰坦灰。除此之外,传统的笔记本电脑也采用了镁合金结构和河蓝色外观。

铝制机身坚固耐用,没有吱吱嘎嘎的扭曲声,而且机身在很大程度上具有防指纹功能。显示屏和键盘几乎没有任何弯曲。铰链坚固耐用,可充分发挥可转换外形的多功能性,但似乎有些过于僵硬,不便于旋转。

铝合金机身的重量为 1.5 千克,而镁合金机身的重量则轻得多,仅为 1.3 千克。

Latitude 7450 2 合 1 上的端口选择与我们去年看到的类似。戴尔再次吝啬于提供专用的以太网端口,但 HDMI 端口升级到了 2.1 版。

在我们的测试设备中没有微型 SIM 卡插槽,但如果需要,你可以选择配置一个。

Latitude 7450 的英特尔 BE200 Wi-Fi 7 无线局域网卡在 5 GHz 和 6 GHz 频段上都能提供强大的性能,而且不会出现传输节流。

这两个频段的吞吐量几乎相同,6 GHz 频段的接收速度比相应的 5 GHz 测试快 3.6%。

戴尔优化器允许同时使用两个连接(有线和无线)以加快下载速度。

遗憾的是,WLAN 卡是焊接的,不能更换。

戴尔只为Latitude 7450 2 合 1 提供了一个 1080p 网络摄像头,而笔记本电脑则可配置高达 500 万像素的摄像头。在环境光线良好的情况下,视频通话的图像质量尚可。

除了电源按钮上的指纹识别器外,还配备了一个红外传感器,用于基于 Windows Hello 的登录。此外,还提供物理网络摄像头隐私快门。

此外,戴尔优化大师应用允许您配置若干存在检测功能,以增强隐私保护。

可持续性

戴尔在Latitude 系列的营销材料中强调可持续发展。据该公司称,铝制产品由 50% 的回收铝和 50% 的低排放铝组成,而镁制产品则采用了 90% 的回收镁。

电源适配器外壳由 95% 的消费后再生塑料制成,内部隔热罩由 98% 的再生铝制成。

此外,戴尔还保证Latitude 系列的包装完全由可回收或可再生材料制成,所有材料均可 100% 回收利用。

输入设备:支持笔和墨水的触摸屏

Latitude 7450 2 合 1 配备了防泼溅 Chiclet 键盘和专用的 Co-pilot 键。按键的键程和触感都不错,带来了非常好的输入体验。两段式白色背光有助于在黑暗中清晰辨认。

13.3 厘米 x 7 厘米的触摸板与去年的产品基本保持一致。虽然点击时的声音略大于预期,但点击有力,行程较深。表面完全支持 WindowsPrecision 手势。触摸板的上角很难点击,但下半部分反应非常灵敏。

作为一款可折叠设备,Latitude 7450 2-in-1 配备的触摸屏可识别十指多点触控和笔输入。戴尔没有在包装盒中提供手写笔,但你可以选择购买戴尔 Active Pen PN5122W,它提供 4096 级压力,售价 40 美元。

显示屏60 Hz FHD+ IPS 面板,无 PWM

戴尔为Latitude 7450 2 合 1 提供 14 英寸 16:10 FHD+ 60 Hz 触控 IPS 显示屏。普通笔记本可选配 QHD+ 触控 IPS 面板。遗憾的是,与大多数商务笔记本电脑一样,更高的刷新率在Latitude 系列中仍然难以实现。

我们观察到,亮度分布均匀度达到了 85%,背光渗漏极少。不过,光滑的表面在光线直射下可能会让人分心。

Display Response Times

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
23.35 ms ... rise ↗ and fall ↘ combined↗ 11.77 ms rise
↘ 11.58 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 50 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
35.65 ms ... rise ↗ and fall ↘ combined↗ 16.01 ms rise
↘ 19.64 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 46 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (32.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

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 ≤ 100 % brightness setting

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8743 (minimum: 5 - maximum: 343500) Hz was measured.

光亮的显示屏在阳光直射下观看会有些不舒服。可视角度相对稳定,在极端情况下亮度或色彩信息不会有大的损失。

性能酷睿至尊 7 165U vPro 可长期支持 44 W PL2

Latitude 7450 2 合 1 机型可配置 英特尔酷睿 5 135UvPro 或 Core Ultra 7 165UvPro。

其他 CPU 选件,如 Core Ultra 5 125U, Core Ultra 7 155U和 28 W Core Ultra 7 165HvPro 可用于传统的笔记本电脑外形。

 
 

测试条件

戴尔通过 Dell Optimizer 应用程序提供了四种性能模式供用户选择,该应用程序需要单独下载,不属于出厂映像的一部分。

我们使用超性能模式进行所有基准测试,使用静音模式进行电池寿命测试。还可以将戴尔优化大师的性能配置文件与 Windows 电源模式同步。

英特尔酷睿至尊 7 165U 虽然不能很好地支持多核,但性能良好

Latitude 7450 2 合 1 的 Core Ultra 7 165U 处理器表现与该处理器的平均成绩相当。

值得注意的是,在单核基准测试中,该设备使用的 BIOS 版本表现不佳。我们建议用户更新到最新的 1.60 或更高版本,以解决这一问题。

联想 联想 ThinkPad X1 2 合 1 G9采用相同 CPU 的联想 ThinkPad X1 2 合 1 G9 尽管运行时的 PL2 功耗为 40 W,但其累积性能与Latitude 不相上下。

不过,在 Geekbench 6.3 单核心和累积 AIDA64 测试中,Latitude 7450 2-in-1 的性能确实略高于 ThinkPad X1 2-in-1。

在 Cinebench R15 多核循环测试中,我们观察到 CPU 节流现象,类似于之前在 Latitude 7440采用 酷睿 i5-1345U.

对 Cinebench R15 多核循环过程中的 CPU 指标进行分析后发现,Latitude 7450 2 合 1 的 Core Ultra 7 165U 在运行开始时可达到 3.27 GHz 的峰值时钟,瞬间功耗为 47.5 W。

虽然 CPU 在测试的大多数循环开始时都试图将功耗水平维持在 40 W 至 45 W 之间,但它很难维持这一水平,最终降至平均 22 W,平均时钟频率为 2.28 GHz。我们在多核功耗测试中也看到了这种模式,稍后我们将进行讨论。

在第 9 个循环中,功耗和时钟速度明显下降,然后才恢复,这与上面循环图中观察到的分数下降一致。


Cinebench R20 多核分数在电池使用情况下下降了 29.8%,而单核性能基本保持不变。

存储设备

只能安装一个 M.2 2230 硬盘
只能安装一个 M.2 2230 硬盘

戴尔在Latitude 7450 2 合 1 中采用了 M.2 2230 NVMe 固态硬盘,而不是传统的 M.2 2280 外形。

我们的设备配备了 512 GB Micron 2550 硬盘,落后于用于 Latitude 7350 可拆卸在整体存储基准测试中落后 6%。

在 DiskSpd 读取循环测试中,固态硬盘的性能相当稳定,节流问题很小。目前还无法添加另一块 M.2 或 SATA 固态硬盘。

Latitude 7450 2 合 1 使用单风扇单热管组合

Latitude 7450 2 合 1 在所有性能模式下都能安静运行,只有在明显负载的情况下风扇才会启动。

在超高性能模式下,风扇噪音水平保持在 40 分贝(A)以下。

我们观察到,在中等图形工作负载(平均负载)时,噪音水平略高于系统在综合满载(Prime95 in-place large FFTs 和 FurMark 1,280 x 720,无 AA)或游戏时的噪音水平。

耗电量

Latitude 7450 2 合 1 中的酷睿至尊 7 165U 是一款省电的产品,其空闲功耗与 AMD Ryzen 7 PRO 7840U 相当。 AMD Ryzen 7 PRO 7840U中的 联想 ThinkPad T14 G4.

它的 Latitude 9450 二合一和 ThinkPad X1 2 合 1(均采用 Core Ultra 7 165U)的总体功耗明显更高,主要原因是空闲功耗更高。

下面的 Cinebench 多核功耗图模仿了我们之前在封装功耗方面的观察结果。

Latitude 7450 2 合 1 的散热系统显然难以长时间维持 48 W PL2 的极限,尤其是在多核负载时。可能是戴尔在核心温度达到 100 °C大关时采用了一些积极的热节流措施。

电池寿命

Latitude 7450 2 合 1 的 57 Wh 电池在 150 尼特的 WLAN 上网和 1080p H.264 循环视频播放测试中提供了良好的运行时间。

特别是在启用动态刷新率的较低亮度水平下使用时,这款可折叠电脑应该可以轻松支撑一个典型的工作日。

随附的 65 W 电源适配器支持 ExpressCharge 快速充电,从 0 开始充满电需要略多于一个小时。

此外,戴尔优化器还提供精细的充电控制,包括动态充电策略和按天充电计划选项。

57 瓦时的电池可提供足够的后备电力,满足一般工作日的需要
