S912 vs rk3399
First of all, this product uses the AMLogic S912 chip, although it is not Haisings, but the AMLogic S912 chip seems to be more cost-effective, and it is also very powerful and positioning high performance terminal products.
As early as a year ago, this chip has already attracted extensive attention, and the market is injecting new vitality into the smart set-top box after half a year. It has 64-bit octacular ARM CORTEXTM A53CPU, the highest frequency can reach 2.0GHz, GPU is ARM MALI-T820MP3 GPU 750MHz, supports HDR10bit 4K @ 60fps video hardware decoding, add point-to-peer display, H.265 support up to 10-bit hard solution Play back to AVS + and other formats, support HDMI2.0A, support CVBS, integrated high performance, low power consumption. This makes the Humei H7 four-generation network set-top boxes using the AMLOGIC S912 chip also destined to have extraordinary performance.
Looking at the memory and adding 2GB, it means that its running speed is satisfactory, there is more time, and the 16GB high-speed flash, larger storage capacity allows users to install more applications with their hearts.
From the perspective of parameters, the H7 four generations of decoding capabilities are also very good, can decode H.265, H.264, VP9, MPEG1 / 2/4, VC-1, WMV format video, support MKV, WMV, MPG, MPEG, DAT, AVI, MOV, ISO, MP4 and other video file formats. The wireless function not only added support 2.4GHz / 5GHz dual-band WiFi, but also added to Bluetooth support, which means that the H7 four generation will support Bluetooth voice control as H6, which can greatly improve operational convenience.
Haimeidi H7 series has always had a good performance and a good reputation. This H7 four generation is equipped with 64-bit 8-core AMLOGIC S912 chip, with 2G memory, 16G flash memory, with dual frequency WiFi, support voice control, very performance outstanding.
Learn about the TV box's classmates to Ruixin Rockchip RK3288, the two chips of RK3368 must be unfamiliar. RK3288 is a chip launched in the beginning of 2014, using quad-core ARM Coretex-A17 kernel architecture, and it has got a lot in the field of domestic tablets and TV boxes. RK3368 is the OTT Box chip launched by Ruixin, using eight core 64-bit ARM CoreTex-A53 kernel architecture, and the Ruixin is slightly fallen in the flat field, start focusing on the TV box.
Although the new RK3368 is optimized for the TV box, its hardware performance is weak than the last generation of RK3288, and the old RK3288 retirement must not be retired, and the RK3368 is maintained to maintain Ruixin's 2015 Jiangshan. In 2016, Ruixin Micro Rockchip turned the gun again, followed by the industry trend, and the moment of the first disclosed VR solution RK3399. It is foreseeable that Ruixin RK3399 will become a new king in 2016. Domestic TV box and VR helmet field.
RK3399 is a six-core processor chip based on the Dual ARM Cortex-A72 + Quad ARM Cortex-A53 architecture. The graphics processor uses ARM MALI-T860 MP4 GPU. Mali-T860 is the latest generation of image processors ARM, with a graphic processing performance, and there is a higher-end MALI-T880. The biggest improvement in the hardware performance of RK3399 is that the dual-core A72 and quad-core A53 crossfire, comprehensive performance has a substantial increase in the previous generation, and is very powerful.
At the same time, the new generation of flagship chip RK3399 has the characteristics of high performance, high scalability, can be used in the hot VR product, tablet, game / TV box product. The mainstream processor of Ruixin Micro Rockchip supports 360 ° panoramic video decoding of 4K resolution, and is also compatible with ordinary 2D and 3D sources, providing hardware resolution for application layers.
In 360 ° VR Cinema, 360 ° VR video application, 360 ° VR movie, etc., hardware equipment supports 360 ° panoramic video will become a hardware standard for VR products. And the human eye sees the corresponding picture, and each step in the middle will produce delays. At present, the world-recognized general people acceptable VR delays below 20ms, otherwise it will cause dizziness and vomiting. Most VR devices are currently not up to standard. Under the optimized algorithm, the VR product delay based on the RK3399 chip can be controlled below 20 ms.
Netizen comments:
Because the newly released RK3399 is more forward-looking, not only all the technical advantages of RK3288, more integrated dual USB3.0 TYPE-C interface, dual ISP pixel processing, support gesture identification, built-in PCI-E interface, etc. Point, the hardware configuration is higher, so it is positioned as a more high-end VR product!
