LG Gram 17 (2024) 笔记本电脑评测--小幅改进和全新酷睿 Ultra 7

摆脱困境?

LG 的新款 Gram 保持了该系列的一贯风格。从外观上看,这款轻薄的 17 英寸设备几乎没有任何变化。在内部,这款笔记本电脑采用了流星湖(Meteor Lake)处理器。不过,LG 已经悄悄地、秘密地消除了我们对测试设备前身提出的一些批评意见。

LG Gram 17(2024 年)

2024 年,LG 继续推出硬件更新的 Gram 17。今年,英特尔酷睿 i7 换成了酷睿 Ultra 7。我们在 2023 年 12 月的首次测试中已经得出结论,由于采用了 Arc iGPU 和 NPU,新 APU 的功能更加全面。因此,最新版本的 宏碁 Swift Go的性能大幅提升。LG Gram 也得益于新的英特尔处理器。不过,LG 并没有给 酷睿至尊 7 155H的空间或功率。

除了新处理器之外,我们几乎无法用肉眼看到这款最轻的 17 英寸笔记本电脑有任何其他更新。LG 似乎没有发现什么需要改进的地方。键盘、触摸板、摄像头和外壳的调整只能在仔细观察或直接对比时才能看到。这意味着自 2021 年以来 LG Gram 17的设计几乎保持不变。

可能的竞争对手比较

在我们对 LG Gram 的评测中,很难找到合适的对比设备,因为这款轻型笔记本电脑几乎没有直接的竞争对手。在尺寸重量比方面,这款笔记本电脑完全是独一无二的。除了 Gram 之外,我们的 17 英寸笔记本电脑数据库中只有游戏笔记本电脑。尽管如此,我们还是挑选出了一系列令人兴奋的对比设备。去年,我们甚至测试了 配备 Nvidia RTX 2050 的 LG Gram 17。.由于 Arc iGPU 的高性能,你不禁会问,如今入门级 dGPU 是否还值得购买?三星 三星Galaxy Book4 Ultra也配备了 dGPU,但它的 RTX 4050是 Nvidia 的最新一代产品。惠普 惠普 Spectre x360 16-aa0074ng微星 Prestige 16 B1MG-001US则展示了英特尔最新处理器的性能表现,只要你给它们更多的动力。

案例 - 三色灰

LG 依然保持了自己的风格,这款轻巧的 17 英寸笔记本电脑几乎看不出任何视觉差异。与之前测试过的 Gram 17 相比,除了颜色之外,我们注意到的唯一变化是该机型的网络摄像头不再位于显示屏上方的凹槽内。除 17 英寸机型外,LG 还推出了 16 英寸版 Gram。这款笔记本有黑、白、灰三种颜色可供选择。我们的测试设备采用的是令人愉悦的灰色。它的漆面经久耐用,与外壳的镁合金结合在一起,形成了漂亮的表面。

和往常一样,LG Gram 给人的感觉有点脆弱,但这款轻巧的笔记本电脑确实经得起摔打。如果你按压键盘中部,它就会轻微弯曲。笔记本电脑显示屏周围的边框要灵活得多。显示屏本身也可以轻微扭曲。不过,在日常使用中,我们还没有发现这会造成任何限制或损坏。在存放笔记本电脑时,你可能需要特别注意保持屏幕和键盘的清洁,这一点可能比其他笔记本电脑更容易做到。我们注意到,键盘上的油渍也会转移到屏幕上。这让我们担心,当笔记本电脑放在背包里时,如果键盘压在屏幕上,灰尘和污垢可能会损坏或划伤屏幕表面。

目前,LG 已经按照 MIL-STD-810H 标准对这款笔记本电脑进行了多项测试。这款笔记本电脑或多或少通过了七项测试。Gram 17 可以承受低压、高温和低温、盐雾和灰尘。它还能承受强烈震动、冲击和高空跌落--至少在装运箱中是如此。在完成由知名实验室进行的所有测试后,这款笔记本电脑仍能正常工作。

LG Gram 其他颜色版本

LG Gram 17 的厚度甚至不到两厘米。只有Galaxy Book4 Ultra 的 17 毫米厚度更薄。反过来,在我们比较的 16 英寸设备中,没有一款比我们的测试样品更轻。只有 宏碁 Swift Go 14的重量也达到了 1.3 千克,但屏幕和外壳却小得多。不过,由于 LG 即将停产 Gram 的小尺寸机型,Swift Go 14 可能会成为所有喜欢小尺寸笔记本电脑用户的替代选择。

连接性 - LG Gram 仍然提供广泛的连接选项

我们也没有注意到这款大型 LG 笔记本电脑的连接方式有任何变化。从外观上看,连接选项多年来没有任何变化。它的网络摄像头和无线局域网仍然保持了前代机型的良好水准。

SD 读卡器

LG Gram 17 的一个小改进体现在它的读卡器上。因此,与前两款机型相比,我们测试中的 Angelbird AV Pro V60 等 microSD 卡的读取速度稍快。

英特尔的 Wi-Fi AX 211 模块可能是过去几年无线局域网的黄金标准。该模块可通过 Wi-Fi 5、6 和 6E 以及旧标准进行连接。不过,一些最新的笔记本电脑型号已经配备了可以通过 Wi-Fi 7 标准连接的模块。WLAN 模块还可以连接蓝牙 5.2。

网络摄像头

Gram 的全高清网络摄像头能拍出不错的照片。反过来,由于摄像头也用于面部识别,它没有红外滤光片。软件会尽一切努力消除由此产生的紫色色调,但并非在所有情况下都能成功。特别是在户外使用网络摄像头时,我们偶尔会发现轻微的紫色偏移。

安全

Intel Core Ultra 7 155H 标配 TPM 2.0。这确保了笔记本电脑的数据安全。Kensington 锁插槽可提供物理防盗保护。

配件

我们没有注意到 LG Gram 的包装盒里有任何合适的配件。除了笔记本电脑本身,你只得到了一个 65 瓦的电源和一条 USB-C 连接线。

维护

LG Gram 的内存是焊接上去的,但如果取下底板,就可以获得一个空闲的 NVMe 插槽。因此,你可以扩展 LG Gram 17 的存储空间。不过,固定底盖的螺丝隐藏在盖板和笔记本前脚下面。除了螺丝刀外,您还需要一个强力吸盘和适当的工具来移除塑料盖,以便打开这款轻巧的笔记本电脑。

保修

在美国,Gram 系列享有 12 个月的标准保修期。

Input devices - Small improvement in keyboard and touchpad

键盘

乍一看,这款笔记本电脑的背光键盘与前代产品并无不同。不过,LG 对其触觉进行了改进。新款 LG Gram 17 的键盘具有更清晰的压力点。这意味着我们唯一可以批评的地方就是它的键程较低,仅为 0.8 毫米--不过考虑到笔记本电脑的机身高度,这也是情有可原的。

触摸板

LG 还对触摸板进行了一些改进。触摸板上的按键现在变得更硬了。我们还注意到,制造商已经成功地避免了将笔记本电脑放在柔软的表面上时出现不必要的按键卡嗒声。

LG 最新一代产品的显示屏一切照旧,但这并不意味着它的屏幕质量很差。分辨率为 2,560 × 1,600 像素的 16:10 显示屏明亮且对比度丰富。我们测得的平均亮度为 387 cd/m²。由于采用了哑光表面,我们没有发现任何恼人的反光现象。您可以通过 LG 智能助理调整屏幕色温。在测量过程中,我们注意到屏幕在中性设置下有一点蓝色调。如果将色温调高两档,那么灰点和白点几乎都能达到目标值,这意味着几乎不会出现任何色彩偏差。不过,这也会稍微降低屏幕的最大亮度。这时的亮度在 LG 规定的 350 cd/m² 左右。

在中性设置下,我们测试设备的显示屏显示出轻微的蓝色调,色彩偏差适中。为了验证这一点,我们还通过智能助理修正了色温。将色温调高两档后,LG Gram 17 显示的色彩非常准确。我们使用 Calman ColorChecker 得出的平均ΔΕ2000 仅为 2.2。

我们使用笔记本电脑的中性色温创建了 ICC 配置文件。如果使用该色彩配置文件,那么目前 LG Gram 17 的显示效果将非常准确。在我们的 3 次测试中,ΔΕ2000 的平均值最差也有 1.27,这个值非常小,即使是经过训练的眼睛也很难分辨出任何色彩差异。

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
25 ms ... rise ↗ and fall ↘ combined↗ 12.5 ms rise
↘ 12.5 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 56 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (20.7 ms).
       Response Time 50% Grey to 80% Grey
25 ms ... rise ↗ and fall ↘ combined↗ 12.5 ms rise
↘ 12.5 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 33 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (32.4 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

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8453 (minimum: 5 - maximum: 343500) Hz was measured.

在户外使用时,即使在阳光直射下,磨砂显示屏表面也能确保良好的可读性。唯一的例外是一些非常不利的视角。不过,得益于笔记本电脑良好的视角稳定性,您可以轻松避免这些问题。

性能 - 低瓦数的 Meteor Lake 处理器

2024 年,每个人都会谈论流星湖。英特尔的第 14 代处理器也已经进入了 LG Gram 17。对于个人用户来说,Gram 17 最初只能搭载 英特尔酷睿至强 7 155H.用户可以选择 16 或 32 GB 内存,以及最高 1 TB 的固态硬盘存储空间。配备 Core Ultra 5 125H版本。只有 LG Gram Pro 才有专用图形芯片。不过,它们的外壳也更像 Gram SuperSlim.16 英寸版本的 LG Gram Pro 还配备了 OLED 显示屏。

测试条件

LG 智能助理
LG 智能助理

可以通过 LG 智能助理设置笔记本电脑的散热模式。从静音运行到风扇非常活跃,可进行四种不同的设置。此外还有自动模式。在测试过程中,我们注意到一项特殊功能。只要在全屏模式下运行 3D 应用程序,风扇就会变得更加活跃。作为 LG 的典型产品,处理器的性能值在这里仍然相当有限。在如此扁平和轻巧的设备中,几乎没有任何空间来进行强力散热。因此,英特尔酷睿至尊 7 155H 的最大升压功率为 45 瓦,持续功率为 22 瓦。我们使用 "正常 "散热模式进行了大部分测试,并使用最高散热设置进行了游戏。在运行过程中,我们观察到以下性能限制:

模式 PL1 PL2
静音 12 瓦 15 瓦
15 瓦 22 瓦
正常 15 瓦 45 瓦
22 瓦 45 瓦

处理器

LG Gram 17 配备了英特尔最新的处理器之一。不过,与前几代芯片相比,Meteor Lake 处理器内核的变化并不大。最重要的变化是新的 Arc iGPU 和 NPU。英特尔酷睿至尊 7 155H 的 6 个性能内核和 8 个效率内核的纯处理器性能 英特尔酷睿至强 7 155H几乎没有变化。不过,新增的两个低功耗高效内核可确保笔记本电脑在空闲时的功耗值大大降低。

LG 通常会将其 Gram 系列处理器配置为相当低的 TDP 值。这一点在我们的测试样品中也很明显。该处理器的功耗仅为几瓦,但性能却低于平均水平。即便如此,低于平均水平的英特尔酷睿 Ultra 7 处理器仍然足以胜任日常工作。但遗憾的是,在处理器性能基准测试中,新款笔记本电脑与 2022 和 2023 款 LG Gram 17 相比并不占优势。在竞争对手中,微星 微星威望 16拥有特别强大的处理器性能。在这种情况下,英特尔酷睿Ultra 7处理器才能真正显示出它的实力。

系统性能

配备 英特尔酷睿至尊 7 155H由于 LG Gram 17 的 TDP 相对较低,其系统性能也有所下降。虽然直接比较 PCMark 10、Crossmark 和其他基准测试结果可以看出,LG Gram 的得分明显低于竞争对手,但在日常使用中几乎看不出差别。应用程序启动迅速,冲浪和流媒体运行流畅。但遗憾的是,由于 TDP 较低,Meteor Lake 远远未能发挥其潜力。

我们首次体验了 英特尔弧形 iGPU宏碁 Swift Go.这让我们看到,英特尔的新 iGPU 有时会比 Nvidia 的入门级图形处理器更快。 LG Gram 17Z90Q-E.AD78G的对比也显示了这一点。

不幸的是,我们希望新的 LG Gram 能击败配备了 RTX 2050在图形性能方面击败老款机型的希望依然渺茫。新款 Gram 的 TDP 设置过低,无法从 Arc iGPU 中迸发出太多性能。

排放 - 如果需要,Gram 17 可以静音运行

噪音排放

LG Gram 17 的一个优点是在办公时通常能保持安静。只要不在全屏模式下启动 3D 应用程序,笔记本电脑就能保持在 32 分贝(A)以下。但是,当在全屏模式下玩游戏或使用其他 3D 应用程序时,Gram 的风扇会突然变得更加活跃。例如,我们使用过时的 3DMark 06 模拟了中等负载情况,而 Prime95 和 Furmark(窗口模式)则模拟了最高负载。我们的测试设备在中等负载下的声音有时比满载时更大。只有在全屏模式下使用 Prime95 和 Furmark 进行的修改压力测试中,新款 LG Gram 17 才发出了高达 44 dB(A) 的噪音。

因此,我们的测试设备发出的噪音大多很低,几乎听不到。不过,由于风扇几乎不会发出任何高频噪音,因此即使风扇以最快速度转动,笔记本电脑的噪音仍然可以承受。如果需要,您可以通过 LG 智能助理直接影响 LG Gram 的风扇噪音排放。这样甚至可以实现静音操作。

温度

与 LG 的其他笔记本电脑一样,LG Gram 17 的外壳也是由镁轻金属合金制成。这也导致表面温度超过 40 °C,已经让人感觉不舒服。幸运的是,笔记本仅在键盘上方和散热器下方的一小块区域显示了这样的温度值。在压力测试中,即使经过一个小时的测试,所有通常会接触笔记本电脑的地方都保持在室温(22 °C)和体温之间的适中温度。

尽管风扇不太活跃,但笔记本电脑仍然保持了相当低的温度。不过,LG 的电源管理是以低 TDP 为代价的。在正常散热模式下,CPU 和 iGPU 的总功耗在压力测试中不到一分钟就降到了 15 瓦。不过,这一情况一直保持不变。处理器温度稳定在 77 °C。

LG Gram 17 右侧扬声器

LG Gram 17 的最大音量为 78 dB(A),与许多竞争对手相比,它的音量并不算大,但仍能带来不错的音效。由于这款轻巧的 17 英寸扬声器内部的两个扬声器向下辐射,其音效在一定程度上取决于表面。与柔软的表面相比,实木更适合营造良好的音效。

电源管理 - 节俭的笔记本电脑

耗电量

虽然我们已经注意到,LG 为 Gram 17 配备的英特尔酷睿 Ultra 7 所采用的低 TDP 会对其性能产生负面影响,但同时也降低了功耗。这款轻型笔记本电脑几乎在所有负载范围内都低于竞争对手。总的来说,尽管 Gram 17 的屏幕更大,但它的功耗却相对较低。

LG Gram 17 内含 77 瓦时电池

LG 的电池容量为 77 Wh,可谓大手笔。我们在电量测量中确定的低功耗值加上其强大的电池,使其在 Wi-Fi 网上冲浪测试中的运行时间超过了 15 小时。在电池寿命方面,只有 微星威望 16的 99.9 Wh 电池在同类产品中更胜一筹。

评价--出色产品系列的微小改进

LG Gram 17 - 由 LG 德国提供
LG Gram 17 - 由 LG 德国提供

与 Gram 系列通常的情况一样,最新的 LG Gram 17 也不是市场上功能最强大的笔记本电脑。LG 并不真正了解如何充分发挥新英特尔酷睿 Ultra 7 的潜力,在功耗方面也没有给芯片留出足够的余地。不过,这在日常办公、冲浪和流媒体播放时并不明显。即使 TDP 较低,该处理器也能提供不错的性能。

这款笔记本电脑的优势不仅仅在于纯粹的计算能力。因此,LG Gram 17 主要表现为安静、节俭和电池友好。它的屏幕大、亮度高、色彩准确,为高效工作带来了真正的价值,因为通常只有重型游戏笔记本电脑才有这么大的显示屏。相比之下,LG Gram 17 是一款真正的轻便设备。笔记本电脑和电源加在一起仅重 1.5 千克。如果你经常移动,那么你可能会喜欢这款笔记本电脑的轻便。

LG Gram 始终是高品质笔记本电脑的代表,尤其是在轻便的同时不失性能。

目前,还没有其他制造商推出 17 英寸的办公或多媒体笔记本电脑。如果在旅行时,既要考虑到每一克的重量,又要保持较大的屏幕空间,那么 LG 笔记本电脑几乎完全是独一无二的。不过,如果你对 16 英寸笔记本电脑感到满意,而且多一点重量也不是问题,那么你会发现有更多 16 英寸屏幕的同类笔记本电脑可供选择。三星 三星Galaxy Book4 Ultra, 惠普 Spectre x360 16微星 Prestige 16都具有更强的计算能力。从表面上看,我们几乎看不出画质有什么不同。在采用雾面屏幕的设备方面,LG 没有竞争对手。

价格和供应情况

新款 LG Gram 17 目前正在制造商网站上销售,起价为 1199.99 美元。.

去年的笔记本电脑在亚马逊的售价为1,199.99 美元
