Apple iMac Retina 5K 27-inch M390 (Late 2015) Retina 评测

Name: Apple iMac Retina 5K 27 Late 2015 3.2 GHz M390 MK472D/A
Brand: Apple

5K第二代。 Apple为全新的iMac Retina 5K更换了新的Skylake架构处理器，以及来自AMD的全新显卡和全新输入设备。精致的工艺和强劲的性能让它足以征服用户，不过它也并不完美。

There is enough space on the big 5K screen.

Besides the new charging feature, the two input devices are pretty convincing (when you use OS X).

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 17903 (minimum: 5 - maximum: 3846000) Hz was measured.

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
20.8 ms ... rise ↗ and fall ↘ combined	↗ 4.4 ms rise
20.8 ms ... rise ↗ and fall ↘ combined	↘ 16.4 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. » 40 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (21.5 ms).
↔ Response Time 50% Grey to 80% Grey
30.4 ms ... rise ↗ and fall ↘ combined	↗ 11.6 ms rise
30.4 ms ... rise ↗ and fall ↘ combined	↘ 18.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 35 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (33.7 ms).

In review: Apple iMac retina 5K. Test model courtesy of edustore.

Apple的Retina 5 K再一次给我们带来了非常好的整体印象。生产商推出了一款搭配高品质机身和优雅外观的设备。它的全新输入设备也终于采用了可充电电池。不过，最吸引人的还是超高分辨率的屏幕。我们在它绚丽的色彩和宽阔的色域前几近哑口无言。

在机身之中，它混合了台式和笔记本电脑硬件，这保证了不错的系统性能。遗憾的是，Apple将Fusion Drive的固态硬盘容量从128 GB降低到了24 GB。它的处理器性能十分不错，而显卡也足够应付最新游戏，不过对这款较老芯片的利用率让人略微失望。如果你打算用iMac来玩游戏的话，那么就不如选择售价更低且更快的设备。

在发热量和噪音控制的方面它表现中规中矩。在通常任务中它的风扇经常处于静止状态。

如果已经有了上一代的5K Retina iMac，那么并没有什么升级的必要。它们的处理器和显卡性能十分接近，而较广的色域覆盖也只对很少一部分用户有意义。

Apple的iMac 5K Retina是一款优秀的产品，不过售价较高。

入门级版本的2100欧元（约14886人民币），如果选择较高配置的话很容易就会超过4000欧元（约28355人民币）。我们的测试机售价2299欧元（约16297人民币）；学生可以享受2150.60欧元的优惠价（约15245人民币）。
