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。Vaidyanathan Subramaniam, 👁 Vaidyanathan Subramaniam (translated by DeepL / Ninh Duy) Published 🇺🇸 🇹🇷 ...
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。

戴尔今年推出了多款升级版Latitude 机型,采用英特尔流星湖处理器。此前我们曾评测过 Latitude 9450 二合一, Latitude 7350 可拆卸和 Latitude 7350现在,我们来看看Latitude 7450 2 合 1 可转换机,它也有传统笔记本电脑外形。
2024Latitude 7450 是戴尔继去年的Latitude 7440 之后推出的中高端商务产品。我们评测的样品采用英特尔酷睿至尊 7 165U vPro 处理器、32 GB LPDDR5x-6400 内存、14 英寸 FHD+ 60 Hz 触摸显示屏、Wi-Fi 7 和 57 Whr 电池。
规格
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。

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。

处理器
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。

系统噪音
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。
