The previous article has separately analyzed how MacBook Air2013 broke through the bottleneck of 600MB/s of SSD on SATA 6Gbps interface. Combined with the use of several days, this article will talk about this Haswell CPU, which is often sprayed with lower energy than the previous one, and the new HD5000 GPU.
The 13 inch MacBook Air, the mid year version of 2013, is still used for this test.
The configuration is as follows:
The MacBook Air was shipped immediately after the WWDC conference, and it was still 10.8.4 Mountain lion without OS X 10.9 Mavericks. However, the developer preview version has been provided for download, and interested friends can try it. The main frequency of Intel i5-4250u 1.3GHz is lower than that of the previous generation i5-3427u 1.8GHz, which is also officially criticized. Next, through several sets of measured data, we will see whether this CPU will really reduce performance and whether the HD5000 will be surprised?
1、 CPU
1. Cine Bench: CPU 3D rendering capability
The MacBook Air 2013 with Intel i5-4250u 1.3GHz achieved a maximum score of 2.44pts.
The previous generation Macbook Air 2012 with i5-3427u 1.8GHz scored 2.6pts.
In terms of 3D rendering, the new MacBook Air is indeed reduced.
2, Geek Bench2: CPU comprehensive processing capacity
Compared with the 2013 version (MacBookAir6, 2 is the new version), the new MacBook Air with lower frequency finally won by 200 points.
The improvement from the third generation Ivy Bridge to the fourth generation haswell is almost invisible, but as a portable mobile work platform, more durable battery life is the key, and students using Air will not do multiple jobs for him, The ultra-low power consumption brought by Haswell has undoubtedly solved this problem, making the battery life of the Air reach an extreme 12 hours (please wait for the battery durability test), so that Apple officials can only withdraw their consistent attitude, saying that "the powerful power of the MacBook Air comes from the new fourth generation Intel Core i5 and i7 processors. This ultra efficient architecture is designed to reduce power consumption while still delivering outstanding performance. Therefore, you can not only use the computer as you like, but also use it longer than before.

2、 GPU
1. Cine Bench: OpenGL graphics performance
The 3D environment for OpenGL testing is a car chase drama.
The HD5000 is impressive. The second HD3000 is almost three times as fast. OpenGL is close to the ATI HD4870.
Since there is no HD4000 model in hand, put another MacBook Pro GT650m. In this way, the gap between HD5000 and GT650m is less than 10fps. It should be less stressful for general mobile office graphics processing.

3、 Actual game test
We chose Torch Light 2 for this test, and the Mac version we agreed to has not been released yet, but the version migrated from PC has already been available. The 3D graphics of this game does not have high requirements for the graphics card itself, but the migration version itself consumes resources, and just pressing HD5000 can barely reach the GPU of the entry game card.
For the integrated graphics card, there is no anti aliasing, and the ambient glow is turned off. The low grain detail is turned on at full resolution and the whole process is smooth. It is strange and there is no pressure. No matter what card is used for shadow details, it cannot be turned on under Mac. It should be a migration problem.
The CPU utilization rate is almost below 40.
4G memory has almost disappeared, after all, it is a transplanted game.
During the whole game, the highest temperature comes from the CPU, which reaches 78 ℃ at the highest point. However, the front (keyboard side) panel has no obvious heating sensation, which does not affect the feel.
Conclusion: As a mobile work terminal, the performance of the MacBook Air is enough. Although Haswell has not brought significant performance improvement to the new Air, it has achieved the same processing performance with lower power consumption. The Air still occupies the top position of the "Ultrabook" with its so-called 12 hours of power free use time (battery test will be in the next phase).
