联想Yoga 7 14 G7评测。采用AMD Ryzen 7 6800U的多媒体敞篷车大放异彩

Ryzen, OLED & USB 4.

通过新的Yoga 7,联想提供了一个非常激动人心的14英寸可折叠机,使用最新的AMD Ryzen 7 6800U。性能值非常好,但该设备的其他部分也达到了要求吗?瑜伽7也许比瑜伽9i还要好吗?
AMD Laptop / Notebook Convertible / 2-in-1 Touchscreen Windows

我们最近评测了联想最新的旗舰型敞篷车,即Yoga 9i 14。 瑜伽9i 14。这次评测的主题,Yoga 7 14,在产品层次上要低一个档次,但由于它使用了相对较新的AMD处理器,因此也不乏趣味。我们只测试了 Ryzen 7 6800U华硕的Zenbook S 13到目前为止,这就是为什么我们非常好奇它在这款14英寸的可折叠电脑上会有怎样的表现。

我们的样品设备,型号为82QF0018GE的Yoga 7 14 G7,建议零售价为1499欧元(约1500美元),配备了上述的Ryzen 7 6800U,一个集成的680M-GPU16GB内存,1TB固态硬盘和90Hz OLED面板。

外壳 - 瑜珈7的铝制外壳

深灰色的Yoga 7 14类似于更昂贵的 瑜伽9i在设计方面类似于更昂贵的Yoga 9i,并且也使用了圆角。显示屏盖也比基本单元略小,这一点在屏幕向下翻转、将可折叠机作为平板电脑使用时尤其明显。这款 瑜伽9i然而,由于在底座上使用了抛光的金属,它的外观更显高档。但Yoga 7的铝制一体成型外壳一点也不含糊:我们的评测样品在稳定性和触觉方面给人留下了非常高质量的印象。底座和显示屏盖子都不会凹陷,也没有吱吱作响的声音。

瑜伽9i的中央铰链没有 瑜伽9i(包括扬声器),这里使用了两个铰链,调整得非常好,有效地防止了显示器的摇晃。单手打开是可能的,但不是那么容易。Yoga 7 14还可以选择浅蓝色(石蓝)。指纹不是一个大问题,至少在我们的版本中不是这样。

瑜伽7 14的重量约为1.4公斤,是折叠式电脑中的领先者之一,但更昂贵的瑜伽9i甚至更薄。附带的65瓦电源适配器是熟悉的联想USB-C适配器,重量为338克。

设备 - 带有USB 4的AMD敞篷车

在重要的连接标准方面没有任何牺牲。除了USB-C和USB-A端口外,还有一个读卡器和一个成熟的HDMI输出。特别是前面的USB-C端口是一个亮点,因为它支持现代的USB 4.0标准。除了内部显示器外,iGPU还可以为三个额外的显示器供电。

SD卡阅读器

Yoga 7 14在左侧提供了一个microSD读卡器,使用了一个弹簧机制。插入时,卡会稍微伸出来,但这也使移除变得更加容易。在速度方面,读卡器的表现一般,我们用Angelbird AV Pro V60参考卡测得的峰值略高于90MB/s,复制图像文件时略低于80MB/s。

沟通

联想部署了一个来自联发科的Wi-Fi模块(RZ616,2x2),除了目前的Wi-Fi 6E标准外,还支持蓝牙5.2。然而,我们无法连接到华硕的参考路由器的6GHz网络。在5GHz网络中,近1.7GBit/s的传输率非常好,而且非常稳定。在测试过程中,没有发现范围或距离方面的问题。

网络摄像头

显示器上方是一个红外摄像头以及一个1080p网络摄像头,包括一个机械快门,但事实证明这有点难用。该摄像头的质量比以前的720p模块有改进,你也可以看到视频会议的改进。

维护

底板用几个Torx螺丝(T5)固定,可以很容易地拆下来。联想在出厂时安装了一个带有适配器的紧凑型M.2-2230固态硬盘,但普通的M.2-2280固态硬盘也可以安装在这里。WLAN模块位于一个额外的盖子下面,用胶带半遮盖着,但可以被替换。否则,用户只能清洁风扇。

键盘

深灰色的Chiclet键盘提供了一个平均的打字体验。笔画很浅,但反馈很精确,键盘相当安静。然而,从质量上看,其他笔记本电脑在输入功能方面提供了更好的服务,我们也主观上喜欢更昂贵的Yoga 9 14的键盘。瑜伽9 14键盘更好一些。白色键盘照明提供两个强度级别,但不能通过传感器自动激活。也没有指纹扫描仪。

大型ClickPad给人留下的印象有点复杂。12 x 7.5厘米的尺寸对于多达四个手指的手势来说是足够大的,而且基本功能也没有问题,但是像许多其他的点击板一样,点击的声音似乎太响了,而且很廉价,这与笔记本电脑的其他高质量印象根本不相符。我们建议只在敲击输入时使用该垫子。

主动笔也包括在内,是电池供电的。它支持4096个压力级别,在测试中功能令人满意,但不幸的是,它不能储存在机箱中或以磁力连接到机箱。

电容式触摸屏工作得很完美。

显示屏 - 90 Hz的OLED面板

子像素网格

视角稳定
视角稳定

Yoga 7 14配备了一块2.8K的OLED显示屏,分辨率为2880x1800像素,格式为16:10。我们已经在其他联想笔记本电脑中遇到过这种面板(LEN140WQ+),如IdeaPad Slim 7i Pro。这里的特殊功能是90赫兹的较高频率,但这需要先在设置中手动激活。与传统的60赫兹面板相比,图像质量,特别是在运动和媒体播放过程中,要平滑得多。一般来说,主观的画面印象非常好。

在亮度方面,我们记录的数值是目前OLED的典型数值,即在正常SDR模式下,最大亮度略低于400cd/m²。只有在HDR模式下,也必须手动激活(如Windows的典型情况),然后在某些明亮的区域,亮度增加到高达592 cd/m²,当画面几乎完全是白色时,甚至达到560 cd/m²。由于OLED的黑值为0,所以对比度非常高,而且没有光晕(OLED面板技术应该是这样的)。然而,频率为360赫兹的PWM闪烁在80%和更低的亮度下出现,这在某些情况下可能会造成限制。视角稳定性非常好。只有从某些角度可以看到轻微的蓝色偏光,这对OLED面板来说是正常的。

使用专业的CalMAN软件(X-Rite i1 Pro 2)进行分析,发现了肉眼看不到的最小色差。然而,色温有些过暖,而且出厂时的颜色也有几个异常值,超过了3的偏差标志。我们能够通过校准来改善显示效果(相应的配置文件可在上面免费下载)。再加上P3色彩空间的完全覆盖,Yoga 7 14因此相当适合视频/图像编辑。

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
1 ms ... rise ↗ and fall ↘ combined↗ 0.5 ms rise
↘ 0.5 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 2 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (20.7 ms).
       Response Time 50% Grey to 80% Grey
1 ms ... rise ↗ and fall ↘ combined↗ 0.5 ms rise
↘ 0.5 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 2 % 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 detected 360 Hz ≤ 80 % brightness setting

The display backlight flickers at 360 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 80 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 360 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 8439 (minimum: 5 - maximum: 343500) Hz was measured.

性能 - AMD Ryzen 7和PCIe 4.0

我们的样本设备配备了一个相对较新的AMD移动处理器,但联想也提供了一个设备,配有英特尔酷睿i7-1260P价格相同。

 
 

测试条件

联想提供了常规的电源设置。电池保护器、智能冷却 性能,可以通过预装的Vantage应用程序或Fn+P组合键选择。在下面的表格中,我们列出了不同模式的TDP限制。

功率设置 功率消耗 最大风扇噪音
性能 45 -> 25 Watt 42,8 dB(A)
智能冷却 32 -> 20 瓦 37,2 dB(A)
电池保护 20 -> 12 瓦 31,2 dB(A)

我们选择了 "性能 "模式来进行下面的测量和基准测试。其他模式的效果也将在本评论的其他部分进行考察。电源模式的简单切换使用户能够快速选择一个较弱的模式,以便从更安静的风扇中获益,例如。

处理器 - AMD Ryzen 7 6800U

这只是我们第二次测试AMD Ryzen 7 6800U,AMD最新的移动处理器有8个Zen3+核心(Rembrandt-U),可以同时处理最多16个线程。最大的核心频率高达4.7GHz--更多技术细节列在这里 这里.

特别是Ryzen 7 6800U的多核性能非常突出,该CPU远远领先于目前的英特尔芯片,而后者也需要更多的电力。

CPU数据--Cinebench R15多循环(红色:性能,蓝色:智能冷却,绿色:睡眠)。

我们的Cinebench循环显示,处理器在几分钟后趋于平稳,功耗为25瓦几分钟,然后多核性能与第一次运行相比下降了约16%。尽管如此,Yoga 7比使用Core i7-1260P 的Yoga 9i更快。你只需看看这里的功耗,因为英特尔处理器在稳定在38瓦特之前消耗了64瓦特,但仍然比Ryzen 7 6800U 的25瓦特慢。这充分说明了目前谁提供的移动处理器效率更高。

英特尔在单核性能方面领先,但这是以高耗电为代价的。总而言之,AMD处理器是更好的选择,而且我们还没有考虑到更好的GPU性能。在电池模式下,CPU性能不会降低。更多CPU基准测试可在 我们的技术部分.

合成基准测试的结果非常好。主观上,系统性能没有批评的余地。该设备的响应速度非常快,在日常使用中没有滞后或卡顿。然而,可以说,这也是目前这个价格范围内几乎所有设备的真实情况。

GPU-Z AMD Radeon 680M

芯片 锐龙680M是一款强大的集成显卡,远远领先于英特尔的 Iris Xe Graphics G7(平均约为40-50%),可以与入门级GPU竞争,如 GeForce MX450或英特尔的新 弧形A350M,特别是在游戏基准测试中。由于视频解码器的存在,播放高分辨率视频完全没有问题。

由于Yoga 7 14的高TDP限制,Radeon 680M也比华硕Zenbook S 13 (合成测试中平均7%)略快。然而,与处理器一样,GPU性能在持续负载下略有下降,Time Spy 压力测试未能通过,为94.2%。在Witcher 3 循环中也有轻微的性能下降。

用Yoga 7 14 AMD玩游戏是绝对可能的。Witcher 3例如,在高细节下运行非常流畅。基本上,许多游戏都可以在高细节下进行;只有像《赛博朋克2077》这样要求非常高的游戏,你才不得不使用最低设置。

在电池模式下,GPU性能不会降低。更多的GPU基准测试可在这里.

温度

铝制机箱在日常使用中保持着令人愉快的凉爽。即使在负载情况下,用户也不必担心表面发热,因为我们在压力测试中测得底部最高温度约为45℃。即便如此,你仍然可以将设备放在你的大腿上。

原则上,我们在压力测试中观察到与纯CPU负载相同的行为:在45瓦的短暂峰值后,最初运行34瓦,几分钟后稳定在24瓦。在压力测试之后,性能没有下降

瑜伽7 14共有四个扬声器(2个2W的低音扬声器和2个2W的高音扬声器),但与更昂贵的瑜伽7 14相比,质量上有明显的差别。瑜伽9i 14扬声器变得相当响亮,但声音出奇的单薄,主观上没有印象。在我们的测量中,该音响系统也没有特别好的表现。

能源管理 - 良好的续航能力,但没有快速充电功能

消耗功率

鉴于高分辨率的OLED面板,特别是在空闲模式下的消耗率是非常有效的。即使是华硕Zenbook S 1313.3英寸的OLED也需要更多的电力。这一点也适用于 瑜伽9i也是如此,尽管它也使用4K OLED。

在负载情况下,我们的评测设备短暂地刮到了65瓦的电源适配器的功率限制,但这个问题在几秒钟后就解决了。在压力测试中,笔记本电脑的功率达到了44瓦,这就是为什么电源适配器的尺寸足够大。

电池寿命

充电过程
充电过程

联想安装了一个71Wh的大电池,在我们的WLAN测试中,可以实现7:13小时(最大SDR亮度)和9:44小时(150cd/m²,相当于最大亮度的67%)的运行时间。在150cd/m²的情况下,视频播放时间甚至可以超过12小时。对于我们的对比组来说,这些都是很好的结果。

一个全亮度的HDR视频在3:15小时内耗尽了电池。根据我们对Alder-Lake移动处理器的经验(以及单核负载下的高功耗),我们预计配备Intel Core i7-1260P 的相同Yoga 7 14的运行时间会稍短。

据联想称,这款笔记本电脑支持快速充电,但我们无法证实这一点。我们在两个USB-C接口上都尝试了附带的65瓦电源适配器和更强的100瓦模块,但充电曲线总是一样的。在设备打开的情况下,充满电需要140分钟;50%的电量在~53分钟后可以使用。

评语--AMD敞篷车发挥了它的力量

在审查中。联想Yoga 7 14 AMD.样品设备由:

新的Yoga 7 14是一个非常有趣的敞篷车,因为联想将高质量的铝制机箱与快速的 AMD Ryzen 7 6800U与目前的英特尔Alder-Lake CPU相比,它提供了更多的多核性能,但需要更少的电力。在相同的配置下,Yoga也可使用英特尔处理器,价格相同,但只提供两个优势,即略微更好的单核性能和雷电4。AMD和英特尔的配置都提供USB 4。

总体而言,该设备在日常使用中表现良好,但OLED面板中存在PWM,扬声器也令人失望。在这方面,更昂贵的 联想瑜伽9i 14更好,但反过来说,它的处理器和图形性能更差。

联想Yoga 7 14是一款采用AMD处理器的极其强大的可折叠机。此外,就效率和明显更快的iGPU而言,AMD Ryzen 7 6800U目前被证明是紧凑型笔记本或敞篷车的更好选择。

与基于英特尔(通常更昂贵)的对手相比,如 HP Spectre x360戴尔Latitude 9430相比,Yoga 7 14 AMD主要提供性能优势。总而言之,它总体上是一个非常好的包装。我们只希望扬声器能更好。

价格和可用性

联想Yoga 7 14 (AMD)似乎在欧洲通过联想的官方网站以不同的价格广泛销售,例如在UK(909.49英镑),the Netherlands(1104.16欧元),法国(1.049.15欧元)、意大利(1097.10欧元)和瑞典(11033.10 kr)。这个名单并不详尽。

然而,在欧洲之外,Yoga 7 14(AMD)似乎还没有到达联想成立的所有国家。在美国、加拿大、巴西、印度和新加坡进行搜索,没有结果。到目前为止,澳大利亚似乎是唯一的例外在澳大利亚,该设备的售价为2,149.00澳元。

价格和供应情况截至2022年9月3日,可能会有变化。建议用户(在适用的情况下)定期通过联想的官方网站检查可用性。
