联想 IdeaPad 5 2 合 1 14Q8X9 评测:经济实惠的高通 ARM 可转换机型
采用 ARM 技术,电池寿命超长。
IdeaPad 5 二合一 14Q8X9 是采用高通骁龙 X Plus 处理器的最便宜的可转换设备之一。不过,即使考虑到低廉的起售价,它的性能也还有待提高。Allen Ngo, 👁 Allen Ngo (translated by DeepL / Ninh Duy) Published 🇺🇸 🇫🇷 ...
结论--配备骁龙和 OLED 技术的廉价可折叠汽车
与旗舰产品骁龙 X Elite 系列一样,以预算为导向的骁龙 X Plus 系列既能提供惊人的电池续航时间,又能将风扇噪音降到最低,尤其是与英特尔或 AMD 产品相比。如果您的日常 Windows 应用程序针对 ARM 硬件进行了优化,那么每瓦性能将非常出色。二合一外形尺寸和标准 OLED 触摸屏分别有助于扩展多功能性和视觉体验。
对于高通公司来说,不幸的是,800 美元的价位上挤满了英特尔和 AMD 的中端替代产品,例如 惠普Pavilion x360 14或 戴尔 Inspiron 14 7435 2-in-1即使在 Ryzen 5 或酷睿 5 级别,它们也能提供比骁龙 X Plus 更可预测、有时更快的性能。诚然,电池续航时间和风扇噪音可能无法与基于高通处理器的 IdeaPad 14 2 合 1 相提并论,但它们仍然非常出色,可以说值得我们为原生 x86 环境和普遍更快的 CPU 和集成 GPU 而做出牺牲。在绝大多数应用程序仍在 ARM 仿真环境中运行的情况下,在同等价位下,选择基于高通公司的 IdeaPad 而不是传统的基于 AMD 或英特尔的 IdeaPad 2-in-1 14 的理由仍然不充分。

IdeaPad 5 2 合 1 14Q8X9(在某些市场称为 IdeaPad 5x 2 合 1)是现有 IdeaPad 5 2 合 1 14 设计的骁龙版本。因此,IdeaPad 5 2-in-1 14 是目前为数不多的同时拥有三大芯片制造商(英特尔、AMD 和高通)处理器选择的机型之一。我们建议您查看我们对 英特尔 和 AMD 版本的评测,因为它们都有许多相似的物理特性。
我们的评测机配备了骁龙 X Plus X1P-42-100 SoC,集成了 Adreno 图形处理器、16 GB 内存和 1200p OLED 触摸屏,售价不到 800 美元。目前没有其他 CPU 或显示屏可供选择。
该领域的竞争对手包括其他经济型 14 英寸可折叠产品,如 华硕 VivoBook Flip 14, 戴尔 Inspiron 14 2-in-1或 惠普Pavilion x360 14.价格较高的 Yoga Slim 7 14Q8X9 Clamshell 可视为 IdeaPad 5 二合一 14Q8X9 的高端版本。

规格
案例
机箱的外盖由阳极氧化铝制成,而底座部分则采用了更为廉价的 PC-ABS 塑料,这是节省成本的常见做法。灰色的哑光单色让人觉得整个机箱只使用了一种材料,但触摸表面时就会发现质量上的差异。
在其他方面,包括 360 度铰链在内,机箱的坚固程度在同价位产品中还算合理。
尺寸与同型号的英特尔或 AMD 版本完全相同,因此重量也几乎保持不变。希望因采用更高效的 ARM CPU 而明显减轻机身重量的用户可能要失望了。
连接性
端口选项与英特尔和 AMD 版本的 IdeaPad 5 2 合 1 14 完全相同,只是不支持 Thunderbolt 设备(如 eGPU)。尽管如此,我们仍然对无需依赖笨重的适配器就能获得多种可用端口表示赞赏。
SD 读卡器
读卡器的性能较慢,但对于一款经济型 14 英寸系统来说也算一般。从我们的 UHS-II 测试卡向台式机传输 1 GB 的图片大约需要 22 秒,而 XPS 13 只需不到 10 秒。 XPS 13.

网络摄像头
标配 200 万像素网络摄像头和物理隐私快门。不支持红外功能可能是为了节省成本。
维护
底部面板仅由四颗 T5 Torx 螺丝固定,维修非常方便。遗憾的是,由于内存模块是焊接的,而且不支持二级固态硬盘,因此内部没有太多可升级的地方。与英特尔或 AMD 版本的 IdeaPad 5 2 合 1 14 不同,WLAN 模块也是焊接的。
可持续性
该机型获得了能源之星 8.0、EPEAT Gold 和 RoHS 认证。不过,联想并未列出在制造过程中使用了任何可回收材料。
配件和保修
包装盒内除了交流适配器和文件外,没有其他附件。如果在美国购买,制造商通常提供一年有限保修。
输入设备
键盘和触摸板
显示屏
很高兴看到 OLED 成为如此廉价的敞篷车的标准配置。遗憾的是,仔细研究其规格后会发现,这款面板缺少了许多现代 OLED 面板所具备的功能。首先,我们的面板刷新率仅为 60 Hz,而不是更理想的 90 Hz 或 120 Hz。其次,原生分辨率仅为 1200p,虽然考虑到 14 英寸的屏幕尺寸还可以接受,但其清晰度远不及许多其他 14 英寸机型,如 Galaxy Book4 Edge 14.最后,亮度不够高,无法支持 HDR 功能。这些主要缺点都是经济型 OLED 面板的表现。当然,与 IPS 相比,用户仍然可以享受到 OLED 的先天优势,如最小的鬼影和更鲜艳的 P3 色彩。

鉴于系统的价格,显示屏在出厂时没有经过校准,这也在意料之中。不过,平均灰度和色彩 deltaE 值还不错,分别仅为 1.6 和 4.51。遗憾的是,i1Profiler 软件与基于 ARM 的系统不兼容。

Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 461.8 Hz | ≤ 100 % brightness setting | |
The display backlight flickers at 461.8 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 461.8 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8698 (minimum: 5 - maximum: 343500) Hz was measured. |
除 0% 外,所有亮度级别都会出现频率为 462 Hz 的闪烁。
约 350 尼特的最大亮度是 14 英寸 OLED 的平均水平。华硕 Zenbook S 14 的 OLED 面板 华硕 Zenbook S 14和 惠普 Spectre x360 14的 OLED 面板的最高亮度也几乎相同。这样的亮度仍然无法满足舒适的室外观看需求,因此用户在室外使用时会感到非常刺眼。相比之下,Apple MacBook Pro 14 的迷你 LED 面板亮度几乎提高了两倍。
性能
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。预装的 Vantage 软件包括六种用于不同使用场景的附加模式,但都不会影响系统的性能水平。
处理器
我们的 骁龙 X Plus X1P-42-100比 骁龙 X Elite X1E-84-100运行本地应用程序时慢约 20%。这使高通处理器领先于竞争对手,如 酷睿至尊 7 155U甚至更新的 Core Ultra 7 258V.不过,如果在模拟条件下,我们的高通处理器反而会比上述英特尔替代产品慢 20% 到 25%。这一不足意味着,即使是更老更便宜的酷睿 i5-1335U 处理器,在大多数情况下也能胜过骁龙 X Plus X1P-42-100,尤其是因为绝大多数 Windows 应用程序尚未针对 ARM 进行优化。

压力测试
在启动 Prime95 压力时,CPU 会飙升至 3.3 GHz,几秒钟后达到 91 C。此后,CPU 会降至 1.9 至 2.2 GHz 的频率范围,以维持略低于 60 C 的核心温度。 AMD 版本的 CPU在类似条件下会稳定在 76 摄氏度,这表明高通版本更倾向于以更低的温度或更保守的方式运行,而这是以性能为代价的。
在运行《赛博朋克 2077》时,集成 GPU 的稳定核心温度仅为 51 摄氏度,在类似条件下也比速度更快的 AMD 版本低得多。

系统性能
PCMark 10 Standard 与 ARM 不兼容,因此我们运行了应用程序基准测试,如下所示。主观而言,与英特尔或 AMD 的同类产品相比,在启动或多任务处理各种应用程序时,延迟时间稍长。这可能很小,但在设备的使用寿命中肯定会增加。

60 Hz 的 4K 视频播放效果完美,没有任何掉帧记录。相比之下,一些运行最新 AMD Zen 5 平台的电脑,如 Beelink SER9或 博弈 M1出现了掉帧现象,表明软件优化效果比骁龙差。
Windows ARM 设备不支持 LatencyMon。
存储设备
该机型仅支持单 三星 PM9C1a42 毫米 M.2 NVMe 固态硬盘,而大多数其他 14 英寸笔记本电脑至少可以支持一个全长 80 毫米的固态硬盘。不过,对于 PCIe4 x4 硬盘来说,性能还是快速可靠的,传输速率相对稳定,最高可达 6000 MB/s。如下图所示,性能有时会略有下降,但随后又会回升到 6000 MB/s,不会出现重大节流问题。

图形处理器性能
根据模拟 3DMark 基准测试,图形性能较差。结果远远落后于最新的 弧 8, Arc 140V或 Radeon 780M/880M 解决方案,这些解决方案在英特尔或 AMD 的最新笔记本电脑上越来越常见。我们的 Adreno X1-45因此更类似于已经过时的 Iris Xe 80 EUs或 Radeon RX Vega 8的选择,即使在运行游戏时也是如此。

游戏性能
从上面的 3DMark 结果来看,游戏性能同样令人失望。大多数游戏只能在最低的 720p 设置下运行,而 《博德之门 3》等要求更高的游戏只能勉强达到 30 FPS。ThinkPad T14s 6 代中的 Adreno X1-85 ThinkPad T14s 6 代比我们的 Adreno X1-45 快 50% 到 60%。尽管如此,这台机器并不是为偶尔或甚至是休闲游戏玩家设计的。
此外,包括X-Plane或Strange Brigade 在内的一些游戏在较高设置下会崩溃,这表明存在潜在的驱动程序问题,而英特尔或 AMD PC 则不存在这些问题。

系统噪音
在中低负荷时,风扇噪音非常小。例如,在运行3DMark 06 时,风扇噪音在第一个 90 秒基准场景结束时最高仅为 27 dB(A),而背景噪音仅为 25 dB(A)。当集成图形处理器受到压力时,也能得出类似的结论。只有当 CPU 承受长时间压力时,风扇噪音才会明显增加,我们记录到的最大噪音水平略高于 41 dB(A)。除此之外,我们的 Snapdragon PC 在类似条件下的噪音明显低于 AMD 和英特尔的大多数替代产品。

耗电量
台式机空转时的功耗在 3 W 到 11 W 之间,具体取决于亮度水平。由于采用的是 OLED 面板,上限范围可能相对较高,尤其是在显示大部分白色时。在运行要求较高的应用程序时,功耗明显低于英特尔和 AMD 替代产品。例如,《赛博朋克 2077》的平均功耗仅为 21 瓦,而 ThinkPad T14s Gen 6 或 MacBook Pro 14 M4 的功耗为 2 倍。 MacBook Pro 14 M4.当然,这些替代产品的图形处理性能也要快得多,因此在GPU密集型应用中,每瓦性能并不一定对高通公司有利。
在运行Prime95等CPU密集型任务时,由于热限制,功耗会飙升至69瓦,然后稳步降至21瓦。与联想ThinkPad E14 G6的酷睿Ultra 7 155U相比,英特尔处理器的功耗要低得多,但在大多数应用中,英特尔处理器仍占据性能优势。
