Snapdragon 835 (generally referred to as Qualcomm Snapdragon processor) is a mobile phone processor developed by Qualcomm in early 2017 to support Quick Charge 4.0 fast charging technology.
Process
Qualcomm Snapdragon 835 chip is based on Samsung's 10nm manufacturing process. Compared with 14nm, the 10nm process will make the chip speed 27% faster and the efficiency increase 40%. The Qualcomm Snapdragon 835 chip area will become smaller.
In October 2016, Samsung announced that it has taken the lead in mass production of the 10 nm FinFET process in the industry. Compared to its predecessor's 14nm FinFET process, Samsung's 10nm process can reduce power consumption by up to 30% and achieve a 27% or up to 40% reduction in power consumption. By adopting a 10 nanometer FinFET process, the Snapdragon 835 processor will have a smaller chip size, allowing OEMs to get more space available in upcoming products to support larger batteries or thinner designs. The combination of process technology and more advanced chip design is expected to improve battery life.
The Snapdragon 660 is manufactured on a 14nm process and is equipped with an eight-core Kryo core for performance guarantee. Qualcomm promised that the Snapdragon 660 will have a 20% improvement in performance over the Snapdragon 653.
Ualcomm officially released the Snapdragon 660 mobile platform. Its biggest selling point is the introduction of functional modules and technologies that were previously only available in the Snapdragon 800 series flagship platform, including the integration of Kryo CPU and Spectra ISP in the Snapdragon 600 series for the first time. And support for some new features, such as machine learning, neural networks, and more.
According to the information released by the Ministry of Industry and Information Technology, OPPO R11 and R11 Plus will be the first to launch the Snapdragon 660, and will also have a 20 megapixel front lens, 16 million pixels + 20 megapixel rear dual camera, professional portrait mode, with twice Optical zoom function.
éªé¾™ 835 and 660 comparison evaluationIn terms of several major mobile phone processor brands, it is Qualcomm is the largest group of manufacturers. We know that Qualcomm has a very good performance in flagship chips, and it is also a favorite among many vendors in the mid-range. Friends who are familiar with the Qualcomm Xiaolong series know that the Qualcomm Xiaolong 600 series is positioned in the mid-end market. Currently, the CPU under the Qualcomm Xiaolong series has a variety of products, such as Qualcomm Xiaolong 660/652/650/625/626 and so on. At present, only the Qualcomm Snapdragon 660 is equipped with very few models, and currently only OPPO R11. And we know that Qualcomm Xiaolong 835 is currently the strongest chip. Recently, some friends have expressed doubts: Which is better for Snapdragon 660 and 835? Today Xiaobian brought you a comparison of the differences between Qualcomm Xiaolong 660 and 635. Let's take a look at it with Xiaobian.
Which is good for Snapdragon 660 and 835? Comparison of Qualcomm Xiaolong 660 and 835
From the comparison of mobile phone CPU parameters, Qualcomm Xiaolong 660 is obviously inferior to Qualcomm Xiaolong 835. Xiaolong 835 has more advanced technology, higher frequency, stronger GPU, wider network support and so on. The only advantage of Qualcomm Xiaolong is lower power consumption.
In terms of basic parameters, Qualcomm Snapdragon 835 is an eight-core processor, 10nm process, the latest Qualcomm Kryo 280 CPU and Adreno540 graphics processor (GPU). and
As a hot chip of Qualcomm this year, the Snapdragon 660 adopts 14nm process, 8 cores, and the new Kryo 260CPU, which is no longer the ARM public version architecture. The introduction of Kryo's independent architecture in the Qualcomm Xiaolong 600 series is undoubtedly to enhance the performance and market acceptance of the Snapdragon 600 series.
As far as the basic parameters are concerned, compared with Qualcomm Snapdragon 660, Qualcomm Snapdragon 835 has obvious advantages in process technology, main frequency and GPU. As for the gap between the various aspects, the following small series brings the data of the running points.
From the point of running test, although the performance of Qualcomm Snapdragon 835 multi-core is not as good as Snapdragon 660, but single core, graphics processor, overall running points should be much better. As Qualcomm's latest Snapdragon 600 series mobile platform, Snapdragon 660 uses a 14nm manufacturing process with low power consumption. At the same time, the introduction of the new Kryo 260 CPU and Adreno 512 GPU, its multi-core performance is very good.
The following is the location of the Snapdragon 660 and 835 in the mobile phone CPU ladder diagram, as shown below.
The position of the Snapdragon 660 and 835 in the ladder diagram
As for this, I believe that everyone has some understanding of the difference between Snapdragon 660 and 835. The article concludes with the current representative models of these two Soc:
Xiaolong 660 represents the model: OPPO R11.
Xiaolong 835 represents models: Xiaomi 6, one plus five, Nubian Z17, Samsung S8 and so on.
Although the Snapdragon 660 has a very large gap compared to the Qualcomm Snapdragon 835, the Qualcomm Snapdragon 660 is undoubtedly the strongest mobile chip in the current Snapdragon 600 series.
