戴尔 Inspiron 14 7445 二合一可转换机型评测:从 Ryzen-U 过渡到 Ryzen-HS
Inspiron 14 7445 2-in-1 是去年 Inspiron 14 7435 2-in-1 的后续机型。 Inspiron 14 7435 2 合 1.新机型的显著特点是不仅过渡到了 AMD Zen 4,而且还过渡到了 Ryzen HS 系列,而不是去年机型上的 ULV Ryzen-U。单凭这一点,其性能提升幅度就有望远超一般的年度处理器更新。
我们的评测机是 Ryzen 7 8840HS 的最高端配置,售价约为 950 美元。而 Ryzen 5 8640HS 则是较低端的 SKU,但所有选项都使用相同的 1200p60 触摸屏。英特尔 Raptor Lake-U SKU 的型号为 Inspiron 14 7440 2-in-1。
Inspiron 14 7445 2-in-1 的竞争对手包括其他经济型 14 英寸可转换产品,如 联想 IdeaPad Flex 5 14, 惠普Pavilion x360 14或 华硕 VivoBook Flip 14.

机箱 - 1000 美元以下机型中的佼佼者
机身同样主要采用铝合金材质,但与前代机型相比有几处视觉变化。最明显的是扬声器网罩的位置发生了变化,从键盘两侧移到了笔记本下方。机身后缘更扁平,边缘和边角更圆润,底部通风栅的设计也略有不同。这些变化大部分似乎只是出于美观的考虑,因为在其他方面的刚性和质感与 Inspiron 14 7435 2 合 1 非常相似。
该机型做工扎实,底座周围几乎没有变形。不过,外盖在受力时更容易弯曲。
尺寸和重量都比以前略大和略重,但差别很小,基本上不会引起注意。尽管如此,与Pavilion x360 14 等替代产品相比,戴尔 14 英寸可折叠笔记本仍然是预算较重的产品之一、 VivoBook Flip 14或 IdeaPad Flex 5 14 都至少轻 100 克。
连接性
Inspiron 14 7435 2 合 1 的所有端口均已恢复,同时在左侧边缘新增了第二个 USB-A 端口。同样,HDMI 端口仍仅限于 1080p 输出,这意味着外接 2K 或 4K 显示器必须使用 USB-C。
SD 读卡器
与去年的机型相比,集成 SD 阅读器的传输速率没有提高。相比之下,惠普Pavilion x360 14 或联想 IdeaPad Flex 5 14 等竞争机型的 SD 读卡器的传输速率都是它们的 2 倍以上。

交流
Wi-Fi 6 和 6E 由 RealTek RTL8852CE 提供,而不是通常的英特尔 AX200 系列,以节省成本。传输速率比较稳定,但比我们在去年 Inspiron 机型上使用的联发科 MT7922 所记录的传输速率要慢。

网络摄像头
标配带物理快门滑块的 200 万像素网络摄像头。没有集成红外功能。
维护
松开 7 颗十字螺丝后,底部面板不费吹灰之力就能弹开。进入机箱后,可以看到与去年的设计相比有几处变化。最显著的变化是不再使用 LPDDR5,而是采用了用户可升级的 DDR5 模块。
配件和保修
包装盒内除了 USB-C 交流适配器和文件外,没有其他附件。如果在美国购买,则适用标准的一年有限制造商保修服务。
输入设备 - 通过更坚硬的按键改进反馈
键盘
键盘布局基本保持不变,只是这次的电源键略微小了一些。另一方面,整体按键反馈感觉比以前更坚硬,尤其是空格键,在旧款 Inspiron 14 7435 二合一或 Inspiron 14 7420 上,空格键的按键反馈明显更软。 Inspiron 14 7420.现在,按下这个特定按键时的声音要比键盘上的其他按键大得多,从而带来更令人满意的键入体验。
触摸板
点击板的尺寸没有变化,仍然是 11.5 x 8 厘米,对于 14 英寸屏幕来说绰绰有余。不过,戴尔这次改进了点击板的反馈,按下时的咔嗒声更响亮、更清晰、更令人满意,而 Inspiron 14 7435 2 合 1 上的反馈则过于松散。行程仍然有点太浅,但其他方面的改进减轻了人们的担忧。
显示屏 - 廉价级 IPS
Inspiron 14 7435 2 合 1 配备了 LG Philips 的面板,而我们的 Inspiron 14 7445 2 合 1 则配备了友达光电的面板。遗憾的是,友达光电的面板并没有提供比 LG 更好的性能,因为它们共享相似的色彩空间、响应时间、亮度水平,甚至对比度,以获得相似的观看体验。不过,作为一款经济实惠的可折叠产品,这些规格都是理所当然的,正如下面的对比表所示。希望最大限度提高显示质量的用户不妨考虑 华硕 VivoBook 14 OLED它的售价与戴尔差不多。

虽然色温和灰度在开箱时都很好,但伽玛校正却有偏差,导致色彩更不准确。使用我们的 X-Rite 色差计进行校准可以解决这个问题,从而获得更准确的色彩,尤其是在较低的饱和度水平下,如下面的 CalMan 截图所示。请注意,由于上述 sRGB 覆盖范围有限,在饱和度较高的情况下,色彩仍然非常不准确。

在经济型可转换笔记本电脑中,暗淡的显示屏比比皆是,Inspiron 14 7445 2 合 1 也不例外。与去年的机型相比,这款笔记本的显示屏亮度并不高,在室外也无法获得同样的观看体验。环境光线很快就淹没了光面屏幕,导致眩光和色彩失真。用户必须升级到价格更高的机型,从 XPSYoga 9、Spectre 或 EliteBook 系列中价格更高的机型,才能获得更好的户外可视性。
性能 - 相对便宜的 Zen 4 Hawk Point
测试条件
在运行以下基准测试之前,我们将 Windows 设置为性能模式。该系统没有配备戴尔优化大师,目前只有戴尔 XPS 或Latitude 等高端机型才配备该功能。
处理器
处理器性能 Ryzen 7 8840HS处理器的性能远远超过 Ryzen 5 7530U在单线程和多线程运算中,分别领先去年 Inspiron 14 7435 2 合 1 中的 Ryzen 5 7530U 多达 25% 和 50%。在一年的时间里,这已经是一个相当大的性能飞跃,但这主要归功于 HS 系列 CPU 提供的更高功率包络线。
不过,从更大的角度来看,Zen 4 Ryzen 7 8840HS 的运行速度要慢于 Zen 3+ Ryzen 7 7840HS慢了约 20%。这可以归因于较低的功耗上限(28 W 对 35 W),正如我们的 GPU 部分所显示的那样,这也对图形性能产生了负面影响。
性能的可持续性也并非完美。例如,在循环运行 CineBench R15 xT 时,最初的 1900 分会随着时间的推移下降约 11%。值得称赞的是,戴尔在多次循环后才开始出现节流,因此 Turbo Core 的性能至少可以持续几分钟。
集成的 NPU 也值得一提,因为它有助于进一步将 Ryzen 7 8840HS 与 Zen 3+ 或更早的架构区分开来。不过,截至本文撰写之时,在 Windows 集成更多人工智能增强功能之前,它的应用还非常有限。

图形处理器性能 - Radeon 780M
图形性能比我们数据库中配备相同集成 Radeon 780MGPU 的笔记本电脑平均水平低 15%,尽管这些笔记本电脑大多采用的是较早的 Zen 3+ CPU。造成这种差距的部分原因是采用了新的集成 NPU,而且上面提到的核心时钟频率普遍较慢,这些都会影响集成图形处理器的性能。因此,Inspiron 14 7445 2 合 1 中的 Radeon 780M 性能更接近于旧版的 Radeon 680M.

系统噪音
在运行浏览器或视频流等要求不高的负载时,风扇噪音非常小,这与我们在 Inspiron 14 7435 2 合 1 上体验到的情况类似。像连续启动几个应用程序这样的处理峰值会导致风扇噪音暂时上升到 34 dB(A),然后回落。
当长时间运行要求更高的负载(如游戏)时,风扇噪音最大值略低于 44 分贝(A),比我们在去年的机型上记录的噪音略大。换句话说,Inspiron 14 7445 2 合 1 只有在压力较大时才会比上一代机型噪音更大,否则它们之间几乎没有差别。

温度
热源位于机箱左侧,当长时间运行苛刻的负载时,C 盖和 D 盖的温度分别高达 42 摄氏度和 50 摄氏度。系统运行温度明显高于前代产品,平均温度超过 10 摄氏度,部分原因可能是过渡到了要求更高的 HS 系列处理器。大多数竞争对手的运行温度也比戴尔低,包括 联想 IdeaPad Flex 5i 14.如果 CPU 使用率较高,我们建议将系统放在平面或桌面上。

压力测试
在启动 Prime95 压力测试时,CPU 会提升至 3.8 GHz、92 C 和 38 W,几秒钟后又迅速降至 3.2 GHz、83 C 和 30 W。如下图所示,几分钟后将进一步降至 2.3 GHz、63 C 和 20 W。戴尔在运行 Ryzen 7 8840HS 时有些保守,因为在较大的 HP Envy x360 16在类似的测试条件下,Ryzen 7 8840HS 会在更快的时钟频率(3.1 GHz)、更高的温度(77 C)和更高的功率水平(25 W)下保持稳定。
运行时 Witcher 3时,GPU 时钟频率和温度将稳定在 1511 MHz 和 58 C,这同样是非常保守的目标。而上述惠普公司的测试结果则分别稳定在 2180 MHz 和 68 C。

耗电量
功耗与我们去年在 Inspiron 14 7435 2 合 1 上记录的相当接近,有时甚至略低。运行游戏或 Prime95 时例外,Ryzen 7 8840HS 可以提供更快的初始 Turbo Core 性能,但几分钟后最终会出现节流。在初始性能较高时,Inspiron 14 7445 2 合 1 的功耗会比上一代产品高出几瓦。从每瓦特性能的角度来看,结果仍然非常可观。
游戏几分钟后,耗电量会下降很多。运行 Witcher 3为例,测试开始时的功耗高达 50 瓦,6 分钟后功耗降至 35 瓦或更高。
我们使用小型通用(11.3 x 5 x 2.7 厘米)65 W USB-C 交流适配器记录的临时最大功耗为 63 W。

电池寿命
尽管电池容量没有升级,但运行时间比以前略长。我们可以记录 13 个多小时的 WLAN 实际浏览时间,而去年的机型仅为 11 个小时。这一提升足以使 Inspiron 14 7445 2 合 1 成为同尺寸转换机型中续航时间较长的机型之一。
从空电到满电的充电时间相对较慢,为 2 到 2.5 小时。

评语:性价比高,速度快,功能多
Inspiron 14 7445 2 合 1 拥有一系列值得称道的功能,包括可转换外形、最新一代 Zen 4 Ryzen-HS CPU 和 AI 就绪集成 NPU,而所有这些都不到 1000 美元。从 Ryzen-U 跃升到 Ryzen-HS 可能是最显著的变化,特别是对于多任务处理者、休闲游戏玩家或图形编辑来说,他们都能从更快的 CPU 中受益。这也让戴尔在与竞争对手的竞争中占得先机,例如 HPPavilion x360 14, 华硕 VivoBook Flip 14和 联想 IdeaPad Flex 5 14仍在使用 U 系列 CPU。
不过,作为一款经济实惠的可折叠本,偷工减料在所难免,当然也有一些值得警惕的地方。更具体地说,Inspiron 14 7445 2 合 1 尽管采用了相对较快的处理器和较小的外形尺寸,但由于显示屏色彩和亮度有限,因此对于大多数图形工作和室外使用来说都不太理想。此外,Inspiron 14 7445 还不支持 USB4,这意味着它的扩展坞功能非常有限。如果这些功能对您来说很重要,那么您必须升级到戴尔Latitude 系列系列,其价格可能是 Inspiron 的两倍。
Inspiron 14 7445 2 合 1 不仅速度快,而且输入舒适,它还为人工智能革命做好了准备,而且价格实惠。不过,显示质量还有待提高。
Inspiron 14 7445 2 合 1 的有力替代品可能是 华硕 VivoBook 14XVivoBook 14X 提供 OLED、独立GeForce RTX 显卡,重量更轻,价格却与 Inspiron 14 差不多。它可能没有可转换设计,但其原始图形性能和卓越的图像质量可能会弥补这一不足。
价格和供应情况
戴尔现在为我们提供的配置是 Ryzen 7 CPU、16 GB 内存和 1 TB SSD,售价为 950 美元。配备 Ryzen 5 的低端配置,内存和存储空间仅为 Ryzen 5 的一半,售价为 730 美元。
