Both processors are a great addition to the premier family of premier deco-core SOCs. Do you remember, the manufacturer previously launched Helio X20 and X25. Thus, this family is very powerful and can compete with any brand processor. We decided to compare it with Qualcomm Snapdragon 820. Snapdragon 820 is one of the best processors of American chip makers. So let's see how a newbie can fight a veteran.

Based on what is known about Helio X27, we will compare it with the most popular and most impressive processors 2016, Qualcomm Snapdragon 820.

A SOC (system on a chip) is a multi-functional chip in a smartphone. This chip is the mobile phone CPU, GPU, and DSP. This means SOC is the main processor, graphics card, and for controlling aspects of video and audio systems.

Some time ago when we talked about 'the brain of a digital device or computer, we call it the CPU (Central Processing Unit), which is accompanied by various chips like GPU (Graphics Processing Unit), memory controller, dedicated video and audio chip (DSP) and many more. But the manufacturer decided to integrate a significant part of the electronic system in one chip. So we are dealing with system-level integration. But you have to take into account the fact we are not talking about the number of transistors being combined into one, it is a function to be integrated. Therefore, the term SoC (System-on-a-Chip) means one chip including many different functions.

SoC = CPU + GPU + memory controller + DSP + radio network + ...

There are currently four different SOC processors. This processor includes MediaTek, Qualcomm, Exynos, and Kirin. Although rumored Chinese smartphone company Xiaomi make their own processor that will be launched in future mobile broadcasts.

However, this list will be enlarged through Xiaomi, which will launch its own chip-based smartphones codenamed Xiaomi Meri or Xiaomi Pinecone In-House Chip. The latter has been leaked several times, and it seems it will first appear on Xiaomi Mi 5C.

As for GPU, there are three main designers in this -ARM Qualcomm market, imaginoation. This ARM is known as the Mali GPU. Qualcomm GPU is popular because of the Adreno series. And finally, Imaginatio comes with its PowerVR range. But it's very difficult to compare them by considering only the specifications written on paper, because all of them use OpenGL ES 3.1, Renderscript, and GigaFLOP high numbers. The actual results can be displayed simply by testing them in 3D games.

Anyway, all these manufacturers make chips for all smartphone ranges ranging from low-end devices and finishing with top-notch models. With the launch of MediaTek Helio X27 this competition has become rough. So let's see what features are there.

MediaTek Has a lot of competition in this market because every smartphone manufacturer requires SOC in their products. Snapdragon is the best in the market, and MediaTek is a big competitor.

From what we know about the X27, it has a core deca processor. This processor is designed for functions that run at different frequencies. This GPU is interesting because its speed is about 875 MHz.

Another processor similar to MediaTek such as X20 and X25. Other similarities include ISPs (picture processor signals) and modems.

MediaTek Helio X27 has a family of chips, where we can also find Helio X20, X25, and X23. All of them use the same deca-core, CPU configuration (two ARM Cortex-A72 cores for heavy work and two quad-core Cortex-A53 clusters for medium to light work). Small cores are specially designed for low-power operation. The main differentiation factor between the four SoCs is the clock frequency. It's clear the highest frequency can be seen in X27 (2.6GHz / 2.0GHz / 1.6GHz for (A72 / A53 / A53)).

SoC is also equipped with ARM Mali-T880MP4 GPU that runs up to 875MHz. So almost reaching 900MHz frequency seen in the Hisilicon is Kirin 950/955, which uses the same GPU.

MediaTek Helio X27 is manufactured on 20nm TSMC process, and as the manufacturer does not make layout changes, clock frequency can not be higher. Therefore, the high frequency ARM target is only at 14nm / 16nm FinFET process. X27 still includes MediaTek Imagiq ISP and integrated Category 6 modem.

ISP still supports for dual camera sensor (color + monochrome configuration), which means it comes with a low light photography improvement. Plus, there is also a 3D depth engine built to enable post-processing DOF effects. It supports up to 32MP sensors at recording resolution of 3840 x 2160 pixels.

MediaTek Helio X27 supports 2560 x 1600 pixels (WQXGA) resolution at 60 fps and 1920 x 1080 pixels (Full HD) at 120 fps with 12Hz Blending layer.

MediaTek Helio X27 has a new function as well. There is a Smart technology that apparently reduces power up to 25%. It also includes other features such as sensor hub and SmartScreen.

2015 is not a good year for Qualcomm in the high-end market. Though Snapdragon 810 was the first AArch64-capable ARMv8 SoC of the company, it failed completely. Probably, the main reason is related to the planar 20nm manufacturing process. More precisely, as many manufacturers think Snapdragon 810 can not make good use of its very ARM Cortex-A57 core clock.

Snapdragon 820 has many features that make it popular for smartphone manufacturers to use. Many of the processors are specifically designed for Snapdragon 820.

For example, the CPU, which Qualcomm makes is called Kryo, has four cores combined. Qualcomm based GPU on the type you can find on PC. Also DSP is now running tasks associated with it rather than using a CPU or GPU.

Another feature that makes the 820 so popular with all mobile brands is that it has an advanced LTE modem. This modem allows high upload and download speed.

With the launch of Snapdragon 820 everything changed. The SoC is equipped with a newly developed Qualcomm CPU core called Kryo. Two of the four cores are designed for high class performance, therefore, they are clocked 2150MHz, while the next two cores are low-power cores clocked at 1593MHz. Interestingly, the CPU architecture of both groups is the same. The only difference is with cache configuration and power / frequency setting.

Adreno 530 GPU is in SoC too. This is the new design of Qualcomm's carrying function previously found only on desktop PCs. Not talking much about technical changes, the most significant step forward compared to Adreno 400 is the graphics side supporting OpenGL ES 3.1 + AEP and Vulkan.

There is a new image processor signal (ISP), which takes data from the camera and generates the photo itself. ISPs are becoming more important, as smartphones get thinner leaving little room for the camera. As for Qualcomm Snapdragon 820 ISP, it's called uniquue-Spectra. Device with Spectra ISP support up to 25MP camera with no lag. One of the most exciting features of this processor is capturing multiple focal depths simultaneously. Thus you can change the focus on any part of the scene after the picture is taken. Snapdragon 820 supports 4K video on 60fps recording.

Another major change is that Snapdragon 820 comes with a new DSP block, the Hexagon 680, which has been designed to handle significant computing workloads for VR, AR, image processing, video processing, and computer vision. Thus the tasks associated with this process will run on DSP instead of CPU and GPU.

HELIO X27 COMPARED WITH Snapdragon 820

Umi Z has announced they will be the first to use the X27. It will not be known if X27 is better than Snapdragon 820 until Umi Z releases new phones. Based on what we know; It seems Helio is a possible alternative to Snapdragon. However, one of the first companies to announce plans on a new device packed with this chip is the Union. The latter has been busy making brands more popular in the international market. Thanks to many flagships like Umi Super, Max, Plus and Plus E (first phone powered with P20 MediaTek) the company can declare it succeed. The list is completed on the Zi Release recently. You can do it right - Umi Z will be the first smartphone equipped with MediaTek Helio X27 SoC.

Umi Z sports all-metal housing, 5.5-inch Full HD sharp screen covered with 2.5D glass bow (Dragontrail), 4GB AMSUNG eMMC5.1 RAM, 32GB of internal memory expandable up to 256GB via SD card slot, Samsung's 13MP rear camera S5K3L8 with quad LED Flash seen on iPhone 7 and 7 Plus which also supports 4K video recording, same sensor on the front (wow) paired with LED softlight, NXP-TFA9890, high-efficiency D-class audio amplifier, 3780mAH battery provides up to 2 Day of normal usage and can be charged in 100 minutes thanks to USB Type-C and MediaTek Express Pump + fast charging technology. Umi Z comes with Android 6.0 out of the box, but will be updated to Android 7.0 Nougat in the nearest future. Finally Umi Z costs just $ 279.99, which means you can get a great smartphone for a song.

As for Snapdragon 820, the SoC is on the market for a long time and there are millions of smartphones powered with it. Among them we can call Lenovo Zuk Z2 / Pro, OnePlus 3, Xiaomi MI5, Leeco Le Max 2 and more. However, the first smartphone featuring SoC is Le Max Pro, worth 1,799 yuan ($ 258.6). So the mind as a Snapdragon chip is way more expensive than the MediaTek chip disappears when it comes to chinese manufacturers.

One more thing, no matter how powerful Snapdragon 820 and how popular it is in 2016 (this chip can be found in over 100 models), there is one problem that we will turn a blind eye on never - the SND820 has an overheating problem, which is solved immediately .

To close, MediaTek just released a new SOC that may be equivalent to Qualcomm's Snapdragon. We will not know if Helio X27 is big or terrible until Umi Z releases next. Based on available information, it seems that the X27 will be as big as the Snapdragon 820.

Many think MediaTek Helio X27 and Qualcomm Snapdragon 820 can not be compared, because American manufacturers have launched Snapdragon 821 and also work on the next SoC gene dubbed the Snapdragon 835. The latter will come with 10nm chips and eight cores of the Kryo 200 processor. Soon, it will bring a lot of goods to market, and it will be very difficult for other manufacturers to compete with this brand. This means, most likely we will have the same image of what's in 2016 - MediaTek SOCS will be on a low-end and mid-range handset, while the top of the brand and high-end smartphones will be powered with SND processors. In this case, it is quite reasonable to compare Helio X27 with Snapdragon 820, because if you want to take the latest peeps and the strongest SoCs from MediaTek and Qualcomm, we should compare Helio X20 and Snapdragon 821.

Anyway, when Snapdragon 820 became available, it tested and hit a record of 136.383 points in AnTuTu. It was a step forward of Apple A9 and Samsung Exynos 8890 which scored 132.657 and 129,865 points, respectively (printing SoCs resting below 90,000).

As for Helio X27, it was tested on one device, Umi Z and scored 116.486 points at AnTuTu. So that's way better than many of the other SoCs, but it still generates its few major competitors. On the other hand, producers can improve performance, because the X25 value is only 98.930 points.
