Virtual Reality (VR), also known as VR technology or artificial environment, is a virtual world that uses computer simulation to generate a three-dimensional space, providing users with simulations of visual, auditory, tactile and other senses, allowing users to As if you are immersed in the situation, you can observe things in the three-dimensional space in a timely and unrestricted manner.
First proposed in the early 1960s, the use of computer systems and sensor technology to generate a three-dimensional environment, creating a new state of human-computer interaction, by mobilizing all the user's senses (visual, auditory, tactile, smell, etc.), with Come to a more realistic, immersive experience.
According to Canadian market research institute Canalys, global VR helmet shipments are expected to reach 6.3 million units in 2016, 40% of which will be sold to China. The global VR hardware and software production value will reach 6.7 billion US dollars, and will grow to 70 billion US dollars in 2020. The industry will usher in explosive growth.
Nowadays, almost all IT giants including Facebook, Alphabet, Google, Sony, Samsung, Intel, Qualcomm, NVIDIA, AMD are all working in the virtual reality field. This means that the emergence of VR devices has become the golden key to the activation industry. From upstream chips and panel makers, to intermediate device manufacturers, to downstream content and service providers, there are great prospects. VR will bring a new IT market to the manufacturers, and will also bring users a new world at your fingertips.
The VR core chip is as follows:
1, Qualcomm Xiaolong 820
As the most well-known chip supplier in the industry, Qualcomm's chip is undoubtedly the most popular. Snapdragon 820 uses Qualcomm's self-designed 64-bit architecture, using four Kryo cores, the highest frequency is 2.2GHz, using Samsung's 14nm FinFET process, supporting fast charging 3.0 technology, equipped with graphics processing chip Adreno 530, DSP digital The signal processor is the Hexagon 680, which uses a new Spectra 14-bit dual ISP processor for image processing capabilities, supporting up to 28 megapixels/30fps and throughput of 1.2 GPix/sec (1.2 billion pixels per second).
Snapdragon 820 supports dual channel memory LPDDR4-1866, supports eMMC 5.1, UFS2.0 (Gear3), SD 3.0 (UH SI), supports USB 3.0 input and output, and supports universal loan compression technology.
2, MediaTek Helio x30
The Helio X30 will be officially released in mid-2016. In addition to continuing the ten cores (six A72 plus four A53s), the Helio X30 will also upgrade memory from LPDDR3 to support LPDDR4 and join the high-speed storage standard UFS. Recently, there is an official news that the "Helio X30" will be changed to a 10nm process, and TSMC will operate the knife. The new product will be sampled at the end of the year and will be mass-produced early next year.
The Helio X30 is equipped with four Cortex-A72 cores (clocked at 2.5GHz) for heavy duty tasks. In addition, it is equipped with two Cortex-A72 cores with a frequency of 2.0GHz, two Cortex-A53 cores with a frequency of 1.5GHz and two Cortex-A35 cores with a frequency of 1.0GHz. At the same time, the Helio X30 will also integrate ARM's latest Mali-T880 graphics card. The Helio X30 also supports 2K & TImes; 2K resolution VR virtual reality technology by plugging in the phone.
3, Samsung Exynos8890
Samsung officially released the new generation flagship processor Exynos 8890, 14mm FinFET LPP process manufacturing, eight core big.LITTLE architecture design, the first use of four self-customized large core (codename "Mongoose" Mongoose) + four Cortex A53 small The core is a semi-autonomous architecture. Compared with the previous generation Exynos 7420, the performance is improved by more than 30%, and the power consumption is reduced by 10%.
The GPU is an absolute highlight. The same as the Huawei Kirin 950, the Mali-T880 is selected, but the suffix is ​​"MP12", and 12 cores (16 in total) are opened. The performance is naturally improved. In contrast, Kirin 950 has only four cores. Compared with the previous generation Mali-T760 GPU, the Mali-T880 has 1.8 times better performance and 40% more energy efficiency. Native 10-bit color difference supports high fidelity 4K display, fully supporting current and next generation APIs. The baseband, like the Snapdragon 820, supports the Cat.12/Cat.13 standard, and the theoretical download speed is increased to 600 Mbps and 150 Mbps is uploaded.
The xynos 8890 is Samsung's first self-designed GPU architecture chip. It has four Mongoose autonomous architecture cores and four A53 public version architecture cores. Although the results are not low, it seems that the performance of the Mali-T880 MP12 is not too good. Normal, basically it is similar to the previous generation Mali-T760 MP12, it may not be optimized.
