HDI is the English abbreviation for High Density Interconnector. High-density interconnect (HDI) manufacturing is one of the fastest growing areas in the printed circuit board industry. From the first 32-bit computer from HP in 1985 to the large client server with 36 sequential multi-layer printed boards and stacked micro-vias, HDI/mini via technology is undoubtedly the future PCB architecture. Smaller ASICs and FPGAs with smaller device spacing, I/O pins, and embedded passives have shorter rise times and higher frequencies, all of which require smaller PCB feature sizes, which drives Strong demand for HDI/mini vias.

Foreword:
At this year's International Consumer Electronics Show (CES), domestic chip maker Fuzhou Rockchip Electronics Co., Ltd. officially launched the RK3368 processor. The Rockchip RK3368 processor is equipped with eight 28-nm process processes and eight Cortex-A53 cores that can be operated simultaneously at high load. The octa architecture operates at 1.5GHz. In the past few months, intelligent network set-top boxes equipped with this processor will also be available one after another. Haimei Di Mango Q and Tianmin will be the first to take the lead in launching a network-smart set-top box equipped with this processor: Haimei Di Mango å—¨ Q H7 third-generation and Mortimer D8 64-bit eight-core version. This time our HDP evaluation room made a detailed comparative evaluation of these two models.
First, processor introduction:
The Rockchip RK3368 processor is equipped with eight 28-nm process processes and eight Cortex-A53 cores that can be operated simultaneously at high load. The octa architecture operates at 1.5GHz. The biggest highlight of the RK3368 is its support for 64-bit operations, which doubles the width of the processor's data stream and has more powerful data processing capabilities. In addition to this, compared with 32-bit processors, the advantages of 64-bit processors are also reflected in the system's memory control. 32-bit ARM processors have an addressing space of up to 4 GB, making large-scale data processing programs that require large amounts of memory appear to be stretched at this time, creating a bottleneck for operational efficiency. Supporting 64-bit RK3368 processors will be able to completely solve the bottleneck that ARM processors are currently encountering in 32-bit computing systems and can support larger-capacity memory. In addition, RK3368 is the second chip that supports 4Kx2K real-time hard solution H.265 after RK3288, and can really realize 4K video output. At the same time, a new H.265 transcoder technology was introduced. Mainly for high-definition video multi-channel real-time transcoding service, various formats of input video can be transcoded into H.265 format video output in real time. Including the RK3368, RK3288 main flagship chip program, Rockchip will also embed the technology in all its chips.
Here it is necessary to briefly introduce the Cortex-A53: Cortex-A53 is the highest performance ARM application processor, claiming to achieve three times the performance of today's top smartphones at the same power level.
Comments: Rockchip RK3368 processor is equipped with 28nm process and eight Cortex-A53 cores that can run simultaneously under high load. Compared with most of the box chips in the past, the advantage is very obvious, especially The powerful Cortex-A53. I believe there will be a very good performance in terms of performance.
Second, the overall appearance of PK: 
1 Mango å—¨ Q H7 Third Generation: Eye View Hoi Mei Di Mango å—¨ Q H7 third generation, and the previous generation has basically adopted a consistent design, external signal receiver, all-metal body material, one piece The cutting process and the color matching of Champagne Gold make the Haimeidi Mango QH7 third generation have a high degree of recognition in many network intelligent set-top boxes.
2 Tianmin D8 64bit Edition: Mortimer D8 64bit body with a matte texture of polycarbonate material, in the fuselage details using more arc design, the front of the fuselage is Tianmin dark gray LOGO. The machine uses sky blue plus white classic Mediterranean color. Compared to its predecessor, the Moran D8, the Mortimer D8 64bit has a similarity to its predecessor in addition to its name and external signal receiver. The others can be said to be completely subversive, regardless of color or appearance. The lower right corner of the Mortimer D8 64bit body is a built-in physical switch button, unique.
Comments: Today's comparative evaluation of the two boxes is a follow-up to the previous generation of products, compared to previous generations are good upgrade products. On the appearance of the comments, everyone has their own preferences, Fan Friends are like the elegant and elegant mango Q H7 third generation or playful and lively D8 64bit it? Or is it like the metal-integrated body of mango 嗨 Q H7 3rd generation or has a comfortable touch frosted texture of Tempest D8 64bit? Fan You’s got their own mind
Third, the external interface PK: 
The left side of the machine, Timor D8 64bit is equipped with a TF card slot and a usb port, mango Q Q7 is equipped with a standard SD card slot 
The right side of the machine, Timor D8 64bit does not have any interface, mango Q Q7 is equipped with 2 usb interface 
The main interface is focused on the back of the machine
1 Mango å—¨Q H7 third generation: interface is distributed on three sides of the fuselage, and the back interface is from left to right: optical audio output, AV interface, network port, HDMI port, reset hole and power port. The left side of the fuselage is the SD card slot. On the right are two USB 2.0 interfaces.
2 Temporary D8 64bit version: The Temporary D8 64bit interface is distributed on the left and the back of the box. From left to left, the backs are: USB2.0 interface, power interface, Fast Ethernet interface, HDMI2.0 interface, 3.5mm composite video AV interface. The left side is also provided with: USB2.0 interface and MicroSD card slot, the largest expansion support 64GB.
Comments: Interfaces, Haimei Di mango Q H7 third generation and Timor D8 64bit are equipped with two USB2.0 interface. The difference is that the third generation of the Sea Medi Mango Q H7 is equipped with a SPDIF optical audio output, so if there is a requirement for local playback of surround sound players, the Q H7 third generation is more suitable. In short, for daily use, such as network online play, such an interface configuration is enough for us.
Fourth, hardware configuration PK:
This evaluation is based on a unified Cpu. The details of the Cpu have been described in detail in the first part, so I will not repeat it here. The second part of the interface is also very detailed. Our part is mainly to look at the memory and other aspects of information. In terms of memory configuration, both models use 1GB of memory and 8GB of storage. In terms of wireless networks, the third generation of Mango Q Q7 and Timor D8 64bit both support 2.4GHz 802.11/b/g/n. Neither support 802.11ac. 
An Bunny 5.7 run points, mango å—¨ Q H7 Run points 37416 is higher than the Mortimer D8 64bit 31792 
The same position wifi signal strength test, the two are very close, slightly stronger Temporary D8 64bit
Comments: The configuration is basically the same, from the security Bunny Run points of view, mango Q H7 three generations is a bit higher than the Mortimer D8 64bit, but the actual value of running this point is limited, here only for reference. After several repeated tests, the performance of the Mango Q H7 running at 3D shows that the 720P is an issue for the security Bunny itself. Both are set to run at 1080P resolution. In terms of wifi signal reception, the performance of the two is not much different. It still seems to look at the system.
Fifth, system UI contrast:
Both of these boxes use the 64-bit RK3368 chip, and the good horse is equipped with a saddle. Naturally, both are equipped with native Android 64 systems supporting 64-bit systems. The native Android lollipop system is quite different from the Android Kitkat on other boxes. The most intuitive experience is the change in the interface. Android lollipop uses a new design language, Material Design. Let's take a look at the experience of Android 5.1 running in these two boxes: 
1 The third generation of mango å—¨ Q H7: The main interface inherits the consistent style of mango å—¨ Q. It is displayed in the form of information from the top, middle, and bottom. The top is the recommended carousel for exciting content. In the middle is the function button, which includes the core content Mango TV. Below is the operation button, the layout is reasonable and logical.
2 Tempest D8 64bit version: The main interface uses the latest WIN8 style magnetic post interface design. Beautiful and simple, more intuitive information, more intuitive operation, easier operation, with cool animation effects, ease of use and convenience greatly improved. The main interface is only divided into three categories: recommendation, video, and application.
Comments: The system UI of the two, the third generation of mango å—¨ Q H7 based on the degree of customization of 5.1 deeper, and the day Min D8 64bit is the current common win8 style. UI logic, the third generation of mango Q H7 just need to look at the main interface at a glance to be able to know all the contents. The Tempest D8 64bit uses the left and right tabs to store the content. These two are the most common and most efficient ways of presentation, depending on the user's own habits.
VI. Online Content PK:
In terms of content, the third-generation license of mango pods Q H7 is mango TV. Everybody knows that Hunan Satellite TV's self-made drama and variety show is the trump card content of the mango TV, and it is also the platform that can be updated for the first time after the broadcast of the TV. Variety in the new speed is very fast. The Tianmin D8 64bit is licensed by Hua Digital Media. The rich content is natural. 
This test sent Temporary D8 64bit prototype did not find the number of applications, but the third-party video data. Three generations of mango pods Q H7 are mango TVs. 
After the daymind D8 64bit is connected to the network, it will automatically install the mainstream video aggregation software on the market. The Mango Q Q7 is only equipped with Mango TV. Others require the user to install it.
Comments: This test sent the Mortimer D8 64bit prototype does not know why did not find in the inside of the official website of the number of TV license providers content. From a normative point of view, the three generations of mango å—¨Q H7 are more in line with the norm, with only mango tv content. From the user's point of view, the Temporary D8 64bit automatically installed the mainstream aggregation software more in line with the user's appetite, reducing the operating trouble.
Seven, local playback PK: 
Comments: Thanks to the support of the RK3368 chip, the two machines handle better compatibility in high-definition video, especially for high-rate H265-encoded 4K sources. Blu-ray ISO images can also be played directly. In the external subtitles, the Tempest D8 64bit is slightly weaker than the three generations of Mango Q Q7, and cannot make adjustments to the color, size, and position of the subtitle font.
Eight, LAN sharing capabilities: 
The day-to-day D8 64bit interface is relatively simple, but it supports samba sharing. The current version of the Mango Q Q7 firmware does not yet support samba shared mounts.
Comments: Tianmin D8 64bit file management interface is relatively simple, but fortunately support the samba sharing function of the network neighborhood, and mango Q Q7 generation does not currently support LAN sharing, according to the official explanation of the next version of the firmware update will solve this problem. As an HD enthusiast, having NAS full of HDDs with multiple HDDs is very much needed for this function.
Nine, PK summary:
The sofa Xiao Bian has compared the three generations of Tianmin D8 64bit and Mango Q Q7 from the aspects of appearance, hard solution configuration, system interface, online content, local playback, local area network and so on. I believe we should be able to make reasonable decisions based on our own needs. chosen.
In general, a friend who prefers to watch network programs can consider the Dmin 64bit, and the friends who need to pay attention to the local high-definition playback recommend the third generation of Mango Q Q7. In the course of this test, we also found that there are still some problems with each machine. We hope that manufacturers can issue new firmware in a timely manner to repair problems and optimize performance.
At the same time of writing this article, and received the news, the RK3368 from Bor and Cloud Network will also be on the market. The sofa editor will record the 2 models at the first time, and make a horizontal comparison. Please pay attention to the most professional TV box. Community, HD Hardware Evaluation Forum.
By the way, to explain the score, after several repeated tests, the performance of the Mango Q H7 running 3D performance shows that the 720P should be the problem of the security Bunny itself, both of which are set to run at 1080P resolution.
