Apple iMac 24 M1 2021年的回顾。Apple'M1 SoC在台式机中也有说服力吗？

Name: Apple iMac 24 M1 2021
Brand: Apple

在书桌上，它变得五彩缤纷。

Apple ，现在iMac也使用自己的M1处理器。配备23.5英寸4.5K视网膜显示屏的新机型取代了之前的21.5英寸机型，并有多种不同颜色可供选择。在测试中，这台台式电脑在许多方面都令人信服，只有大声的冷却是一个惊喜。

外壳、设备和输入装置

iMac的外壳与它的前任不同前辈的不同之处.现在外壳的厚度在所有地方都是一样的（以前是很鼓的），但在显示屏下面使用塑料意味着这款一体机看起来不再那么高质量。下边框的宽度看起来也不是特别现代；这里肯定会有更多的东西。然而，制造质量仍然很好，没有理由提出批评。内置的支架不允许调整高度，只有倾斜角度可以稍微调整。iMac也有集成VESA适配器的版本（~50欧元/~58美元的附加费），但没有包含支架，也不能加装。我们的测试设备采用黄色，看起来非常好，尽管每种口味都应该在这里找到合适的颜色。

4个USB-C接口（2个TB4，2个USB 3.2 Gen.2），电源装置上有千兆以太网。

拥有7个GPU核心的基本型号只在背面提供两个USB-C端口（USB-4/Thunderbolt 3，40GBit/s）。那些选择带有8个GPU核心的配置的用户可以得到两个更多的USB-C端口（3.2 Gen.2），以及作为标准的电源上的千兆以太网插头。Wi-Fi 6和蓝牙5.0也包括在内，尽管WLAN性能（与M1 MacBooks的性能一样）。 M1 MacBooks)有点低（Wi-Fi 6只有80MHz）。然而，在测试中，信号质量非常好。

iMac的这些端口非常灵活，但是当你想快速连接外部硬盘或U盘时，这个位置在实践中不是很实用。我们希望能在侧面看到一个额外的USB接口，类似于左侧边缘的插孔。因此，你很难绕过一个USB集线器。

我们已经知道前辈们的输入设备，特别是TrackPad工作得非常好。由于集成了Touch ID，键盘非常实用，但它只为桌面输入提供很少的行程（与MacBooks相当），而且也没有照明。如果你想写很多东西，你肯定会得到更好的替代品，但它们不能提供所有的舒适功能。

显示器 - 配备4.5K视网膜屏幕的iMac

23.5英寸显示屏提供了非常高的分辨率，即4480 x 2,520像素，像素密度为218 PPI。因此，显示的内容非常清晰，与macOS结合使用也没有缩放问题。IPS面板的主观画面印象非常好，像True Tone（根据环境自动调整色温）以及亮度传感器都非常实用，它们也能完美地工作。

Apple 表示亮度为500尼特，但根据我们的分析（CalMAN Professional和X-Rite i1 Pro 2），我们只能在显示器的中心确认这一点。平均亮度约为480cd/m²。与之前的 iMacs，Apple ，能够减少黑值，这就是为什么对比度（>1,400:1）也更好。我们没有注意到PWM的闪烁，对于IPS显示器来说，响应时间相对较好（没有重影）。

* ... smaller is better

显示屏几乎完全覆盖了P3色彩空间，而且面板在出厂状态下已经被校准得非常好。灰度中没有偏色，所有的颜色偏差都低于3的重要标志。我们仍然可以通过校准来最小限度地改善显示器，但你只能从测量值中看到这一点。因此，新的iMac 24适合无限制地编辑图片/视频。

Display Response Times

ℹ

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
17.6 ms ... rise ↗ and fall ↘ combined	↗ 10 ms rise
17.6 ms ... rise ↗ and fall ↘ combined	↘ 7.6 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 36 % of all devices are better. This means that the measured response time is better than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
29.2 ms ... rise ↗ and fall ↘ combined	↗ 15.6 ms rise
29.2 ms ... rise ↗ and fall ↘ combined	↘ 13.6 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. » 35 % of all devices are better. This means that the measured response time is better than the average of all tested devices (32.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

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 8743 (minimum: 5 - maximum: 343500) Hz was measured.

IPS屏幕的可视角度稳定性非常好。然而，由于光泽的表面，你不应该把iMac 24放在窗户对面，否则你可能会有反射的问题。在全亮度和黑暗的背景下，你也可以看到清晰的光晕。在这方面，以前的iMac要好一些。

性能和排放

该Apple M1 SoC我们已经从 MacBook Air, MacBook Pro 13和 Mac Mini.带8个GPU核心的iMac使用了两个风扇（带7个GPU核心的型号只有一个风扇），这就是性能稳定的原因。其结果与Mac Mini以及MacBook Pro 13持平。在实践中，iMac 24是一个反应极为迅速的系统，但旧的英特尔型号提供更多的性能，特别是在多核测试中。

该系统只在有限的程度上适用于游戏，因为支持的作品不多。然而，由于ARM的基础，你可以访问Apple'的街机系列，你可以从苹果手机和 iPads.我们也非常喜欢6个扬声器，可以轻松取代廉价的外部扬声器。Apple 巧妙地利用了机箱内的空间，内置模块对大多数用户来说完全足够。

我们对大声的冷却感到惊讶。在日常使用中（浏览、视频），系统几乎都是静音的，甚至纯GPU负载也几乎听不到，但在CPU高负载下，两个风扇很快就达到了40dB(A)以上，无论是在原生还是模拟应用中。我们甚至可以测到最高46 dB(A)。当与 Mac Mini相比，新的iMac 24在相同的性能下几乎听不到声音，而在负载下，新的iMac 24的声音就变得太大。

附带的143瓦电源完全够用，而且仍有足够的储备用于Thunderbolt或USB-C配件，因为即使在全亮度的压力测试中，我们也能测出最大约79瓦的能量。

评语--iMac变得太吵了

评测中：Apple iMac 24 M1 2021。测试设备由Apple 德国提供。

新款iMac 24 M1取代了之前的iMac 21.5，主要适用于使用M1处理器的日常任务。在这里，一体机也可以用静音操作来说服人，但在CPU高负荷工作时（如视频编辑），iMac会变得太吵，特别是与Mac Mini M1相比。较大的 iMac 27仍然在产品系列中，并通过英特尔CPU提供更多的性能，还可以配备更多的内存和专用GPU，因此它仍然是要求高的用户的更好（但也更昂贵）的解决方案。

新的23.5英寸IPS显示屏给人留下了非常好的印象，也适用于色彩准确的图片或视频编辑。用户体验得到了改善，特别是由于True Tone或敏感的亮度传感器等功能。新的扬声器系统也很有说服力，可以轻松取代许多廉价的外部扬声器。
