1
00:00:00,000 --> 00:00:02,150
三月苹果更新了Mac产品线之后

2
00:00:02,150 --> 00:00:03,840
我发现一件有点奇怪的事

3
00:00:03,840 --> 00:00:08,060
几乎没什么博主做M5 MacBook Air的测评

4
00:00:08,060 --> 00:00:08,860
讲道理

5
00:00:08,860 --> 00:00:11,730
MacBook Air绝对是MacBook里的中流砥柱

6
00:00:11,730 --> 00:00:14,550
我们去年测试过主动散热的M5 MacBook Pro

7
00:00:14,550 --> 00:00:18,330
今天我们就来看看在M5装进了被动散热的MacBook Air之后

8
00:00:18,330 --> 00:00:19,470
性能表现如何

9
00:00:19,470 --> 00:00:21,320
为了让你直观了解它的性能水平

10
00:00:21,320 --> 00:00:24,690
我们直接凑齐了M1-M5的13寸MacBook Air

11
00:00:24,690 --> 00:00:29,000
来看看到底哪代SoC在被动散热下提升最大

12
00:00:29,000 --> 00:00:31,300
新款MacBook Air除了处理器以外

13
00:00:31,300 --> 00:00:32,880
一切都是熟悉的配方

14
00:00:32,880 --> 00:00:34,670
这次甚至连新配色都没有

15
00:00:34,670 --> 00:00:36,350
所以外观没啥能聊的

16
00:00:36,350 --> 00:00:37,790
直接来看性能表现

17
00:00:37,790 --> 00:00:39,120
先来看看CPU性能

18
00:00:39,120 --> 00:00:43,160
这代M5和前代M4用的是相同的4+6核规格的CPU

19
00:00:43,160 --> 00:00:44,430
架构换成了新一代

20
00:00:44,430 --> 00:00:45,660
频率也有所提升

21
00:00:45,660 --> 00:00:47,860
在被动散热的13寸MacBook Air里

22
00:00:47,860 --> 00:00:50,980
历代Cinebench里的多核成绩都有10-20%的提升

23
00:00:50,980 --> 00:00:53,090
单核的提升幅度在15%左右

24
00:00:53,090 --> 00:00:57,040
多核成绩会比主动散热的MacBook Pro M5低一点

25
00:00:57,040 --> 00:01:00,330
历代里CPU性能提升幅度最大的还是M4

26
00:01:00,330 --> 00:01:04,780
在被动散热的Air里还是能看到M5的CPU能效确实是有进步的

27
00:01:04,780 --> 00:01:07,230
GPU基准测试3Dmark SNL里

28
00:01:07,230 --> 00:01:10,700
被动散热的MacBook Air 13跑出了5098分的成绩

29
00:01:10,700 --> 00:01:13,410
这个成绩比MacBook Pro仅仅是稍低一点

30
00:01:13,410 --> 00:01:16,440
相比前代的M4 MacBook Air还是高了不少

31
00:01:16,440 --> 00:01:18,010
这个30%左右的提升幅度

32
00:01:18,010 --> 00:01:21,450
也是M1-M5当中GPU提升比较大的一代

33
00:01:21,450 --> 00:01:23,130
7-Zip压缩和解压测试当中

34
00:01:23,130 --> 00:01:26,970
M5相较于M4的提升幅度在10-15%左右

35
00:01:26,970 --> 00:01:30,170
被动散热的Air只比主动散热的Pro只低了一点点

36
00:01:30,170 --> 00:01:32,110
因为测试时间并不长

37
00:01:32,110 --> 00:01:34,210
所以它还没到降频的时候

38
00:01:34,210 --> 00:01:35,930
Blender的CPU测试当中

39
00:01:35,930 --> 00:01:39,050
M5相较M4依然保持了10%左右的提升

40
00:01:39,050 --> 00:01:41,850
BMW27场景的这个测试时长不短

41
00:01:41,850 --> 00:01:45,140
被动散热的MacBook Air明显会比MacBook Pro弱一些

42
00:01:45,140 --> 00:01:48,220
基本上这里的提升幅度就取决于能效的进步了

43
00:01:48,220 --> 00:01:49,960
Blender的GPU测试当中

44
00:01:49,960 --> 00:01:52,300
M5这颗GPU表现就相当强了

45
00:01:52,300 --> 00:01:55,130
比起M4的渲染速度几乎快了超过60%

46
00:01:55,130 --> 00:01:58,850
这也进一步印证了M5这代GPU提升幅度比较大的印象

47
00:01:58,850 --> 00:02:01,890
接下来看看Xcode Benchmark编译性能测试

48
00:02:01,890 --> 00:02:05,070
这里M5相较于M4依然是快了10%出头

49
00:02:05,070 --> 00:02:06,930
基本上长时间满载降频之后

50
00:02:06,930 --> 00:02:10,500
M5和M4的CPU差别大概就是这样一个水平了

51
00:02:10,500 --> 00:02:12,130
在PugetBench的测试当中

52
00:02:12,130 --> 00:02:12,830
Photoshop里

53
00:02:12,830 --> 00:02:14,570
M5提升幅度不算特别大

54
00:02:14,570 --> 00:02:17,050
在这个测试里CPU是关键因素

55
00:02:17,050 --> 00:02:20,090
所以你会看到M4这代的提升比较显著

56
00:02:20,090 --> 00:02:21,160
但在PR里

57
00:02:21,160 --> 00:02:23,030
M5的提升幅度就相当可观了

58
00:02:23,030 --> 00:02:26,800
PR对编解码器和GPU的要求比PS要敏感得多

59
00:02:26,800 --> 00:02:28,970
所以M5的性能收益就很明显

60
00:02:28,970 --> 00:02:31,370
M5这代的GPU性能提升很明显

61
00:02:31,370 --> 00:02:34,090
如果你用的软件GPU是参与度比较高的

62
00:02:34,090 --> 00:02:35,560
或者是和AI相关的

63
00:02:35,560 --> 00:02:37,960
那它性能提升的感知是比较强的

64
00:02:37,960 --> 00:02:39,380
比如说这张RAW照片

65
00:02:39,380 --> 00:02:42,760
在Photoshop CameraRAW里我们用它的神经网络降噪功能

66
00:02:42,760 --> 00:02:45,400
把这张Z8拍的高ISO的照片降个噪

67
00:02:45,400 --> 00:02:48,350
你能明显感觉到M5 Air比M4的快

68
00:02:48,350 --> 00:02:50,050
而且因为这个时间不长

69
00:02:50,050 --> 00:02:53,240
所以被动散热的M5 Air也没有比Pro慢多少

70
00:02:53,240 --> 00:02:57,040
同样的情况也出现在Logic Pro的大分轨拆分器里

71
00:02:57,040 --> 00:03:01,330
这个功能是利用AI把一首歌拆成几个乐器分别的分轨

72
00:03:01,330 --> 00:03:02,350
非常有用的一个功能

73
00:03:02,350 --> 00:03:04,970
M5的Air在这里也明显比M4的要快

74
00:03:04,970 --> 00:03:09,090
所以这些利用GPU为主或者AI相关的生产力应用

75
00:03:09,090 --> 00:03:11,990
你能感觉到M5这代的提升是比较显著的

76
00:03:11,990 --> 00:03:12,990
所以很明显

77
00:03:12,990 --> 00:03:15,330
M5这一代的GPU提升才是重头戏

78
00:03:15,330 --> 00:03:16,680
这也让我很好奇

79
00:03:16,680 --> 00:03:19,820
M5放在MacBook Air这种被动散热的机身里

80
00:03:19,820 --> 00:03:21,500
游戏表现会咋样？

81
00:03:21,500 --> 00:03:25,290
MacBook Air 13由于被动散热的原因

82
00:03:25,290 --> 00:03:29,390
游戏里的性能相比于主动散热机型的差距是相当大的

83
00:03:29,390 --> 00:03:33,860
M5会不会凭借着GPU的优秀能效表现给我们一些惊喜呢？

84
00:03:33,860 --> 00:03:35,250
直接上2077试试看

85
00:03:35,250 --> 00:03:38,800
1920x1200分辨率 低画质 不开超分的情况下

86
00:03:38,800 --> 00:03:41,520
M5的MacBook Air跑出了36fps的平均帧

87
00:03:41,520 --> 00:03:43,840
比M4 Air提升了接近35%

88
00:03:43,840 --> 00:03:47,840
这个提升幅度也成为了M1-M5历代里提升最大的一代

89
00:03:47,840 --> 00:03:49,460
看起来在被动散热机身里

90
00:03:49,460 --> 00:03:52,480
M5的游戏能效比M4是有巨大进步的

91
00:03:52,480 --> 00:03:55,200
在开启Metal FX质量档超分之后

92
00:03:55,200 --> 00:03:57,590
M5的Air跑出了54fps的平均帧

93
00:03:57,590 --> 00:04:01,090
比起M4的领先幅度进一步拉大到了接近40%

94
00:04:01,090 --> 00:04:02,980
这颗新GPU确实给力

95
00:04:02,980 --> 00:04:08,160
那么这台Air和同为M5带风扇的MacBook Pro相比又如何呢？

96
00:04:08,160 --> 00:04:11,720
13寸的MacBook Air在持续运行2077这样的游戏时

97
00:04:11,720 --> 00:04:14,340
SoC的功耗稳定下来只有不到10W

98
00:04:14,340 --> 00:04:16,760
在键盘表面温度比较高的情况下

99
00:04:16,760 --> 00:04:19,940
长时间运行之后甚至会降到6W左右

100
00:04:19,940 --> 00:04:23,130
我做了一张不同功率情况下它的2077帧数曲线

101
00:04:23,130 --> 00:04:24,230
你可以参考一下

102
00:04:24,230 --> 00:04:27,350
而带风扇的MacBook Pro在长时间运行之后的功耗

103
00:04:27,350 --> 00:04:29,740
大概保持在20W左右

104
00:04:29,740 --> 00:04:33,770
这样的功耗差距也就带来了40%的实际性能差距

105
00:04:33,770 --> 00:04:36,280
在长时间运行2077这样的大型游戏时

106
00:04:36,280 --> 00:04:41,080
M5带风扇的MacBook Pro帧数差不多要高40%

107
00:04:41,080 --> 00:04:44,030
所以如果你的应用需要长时间满载运行

108
00:04:44,030 --> 00:04:46,970
主动散热的MacBook Pro依然是更好的选择

109
00:04:46,970 --> 00:04:49,360
其他游戏里的情况也和2077类似

110
00:04:49,360 --> 00:04:50,560
在博德之门3当中

111
00:04:50,560 --> 00:04:51,990
1200P低画质

112
00:04:51,990 --> 00:04:54,660
M5的Air在开始时是可以跑到60fps的

113
00:04:54,660 --> 00:04:56,300
随着运行时间变长

114
00:04:56,300 --> 00:04:58,010
逐渐会降低到50fps以下

115
00:04:58,010 --> 00:05:01,420
M4 Air则会在刚开始跑出47-48帧

116
00:05:01,420 --> 00:05:03,770
一段时间之后稳定在30fps出头

117
00:05:03,770 --> 00:05:05,950
M5 Air比M4 Air强不少

118
00:05:05,950 --> 00:05:08,760
但主动散热的MacBook Pro还是明显有优势

119
00:05:08,760 --> 00:05:11,090
基本可以一直稳定在60fps以上

120
00:05:11,090 --> 00:05:12,680
转译的艾尔登法环里

121
00:05:12,680 --> 00:05:14,080
1200P低画质

122
00:05:14,080 --> 00:05:16,100
M5 Air刚开始能跑满60fps

123
00:05:16,100 --> 00:05:18,900
一段时间降频之后会掉到50fps左右

124
00:05:18,900 --> 00:05:22,360
M4 Air则会从50fps左右逐渐掉到30多fps

125
00:05:22,360 --> 00:05:25,560
主动散热的M5 MacBook Pro依然可以全程跑到60fps

126
00:05:25,560 --> 00:05:26,790
这代M5 Air

127
00:05:26,790 --> 00:05:30,830
虽然被动散热下游戏性能相较于前代提升不小

128
00:05:30,830 --> 00:05:32,370
但是和主动散热机型相比

129
00:05:32,370 --> 00:05:34,400
依然有着不小的的持续性能差距

130
00:05:34,400 --> 00:05:37,420
你们也知道续航是MacBook的传统优势

131
00:05:37,420 --> 00:05:39,760
这代MacBook Air 13测下来呢

132
00:05:39,760 --> 00:05:42,190
续航时间是12小时左右

133
00:05:42,190 --> 00:05:45,330
这个成绩基本上和M4的Air没啥区别

134
00:05:45,330 --> 00:05:47,060
还是一个比较优秀的水平

135
00:05:47,060 --> 00:05:50,570
比14寸M5的MacBook Pro短一些

136
00:05:50,570 --> 00:05:51,530
但我要说的是

137
00:05:51,530 --> 00:05:53,450
随着Lunar Lake和Panther Lake的推出

138
00:05:53,450 --> 00:05:56,220
Windows阵营轻薄本的续航表现也逐渐赶上来了

139
00:05:56,220 --> 00:05:59,060
比如说定位相近的小米Book Pro 14的续航时间

140
00:05:59,060 --> 00:06:01,610
也已经有接近10小时了

141
00:06:01,610 --> 00:06:03,580
如果重量稍微重一些的

142
00:06:03,580 --> 00:06:05,580
调校比较用心的Windows笔记本

143
00:06:05,580 --> 00:06:09,290
现在续航是可以做到接近MacBook Air的

144
00:06:09,290 --> 00:06:12,810
简单测试了一下M5 MacBook Air

145
00:06:12,810 --> 00:06:16,390
MacBook Air就是那种你知道它一定不会差

146
00:06:16,390 --> 00:06:20,230
但这种常规更新下很难让你眼前一亮的产品

147
00:06:20,230 --> 00:06:22,500
如果你不好好测试一下它的性能表现

148
00:06:22,500 --> 00:06:26,020
你是不知道M5对MacBook Air的意义到底在哪儿的

149
00:06:26,020 --> 00:06:30,020
M5这代Air的性能提升幅度在历代里都属于相对比较大的

150
00:06:30,020 --> 00:06:31,860
主要是GPU的提升相当显著

151
00:06:31,860 --> 00:06:34,410
加上16+512G起步的配置

152
00:06:34,410 --> 00:06:37,960
我个人觉得它就是目前最值得入手的MacBook新品

153
00:06:37,960 --> 00:06:39,230
不过话说回来

154
00:06:39,230 --> 00:06:42,700
MacBook Air这套模具已经陪伴我们四年了

155
00:06:42,700 --> 00:06:46,460
我还是希望看到下一代MacBook Air能够焕然一新

156
00:06:46,460 --> 00:06:51,630
毕竟吸引人购买MacBook Air最大的理由从来都不会是性能

157
00:06:51,630 --> 00:06:52,460
你说对吧

158
00:06:52,460 --> 00:06:54,410
