mt6799 chip data mt6799 chip data sheet mt6799 chip schematic diagram
MT6799 is also helio X30, which is made of TSMC's 10nm process. Although it continues to use the three-episode ten-core architecture like X20/X25, the core of helio X30 has been adjusted. It can be said that it is a major upgrade. 2 2.8GHz Cortex-A73 CPUs + 4 2.3GHz Cortex-A53 CPUs and 4 2GHz Cortex-A35s! The GPU is a specially customized PowerVR 7XTP-MT4 GPU with a main frequency of 800MHz and supports 4K screen, 8GB RAM, UFS 2.1, etc. 
I believe netizens who have followed ARM A73 and A35 should know that the former ARM is the latest high-performance core, while the A35 pays more attention to low power consumption/power saving. Helio X30 integrates the above three cores, which is obviously a firm performance. Balanced multi-core route with power consumption! Only this time, the processor performance of the helio X30 will be greatly improved, moving towards the flagship level.
My Meizu mobile phone uses this chip, it is still good, then let me see his design data
The MT6799 hardware family is a highly integrated baseband platform that integrates a modem and application processing subsystem. The application processor is a Tri cluster with Neon Engine with multi-core ARM Artemis, ARM CortexA 53 MPCoreTM and ARM Cortex-A35 MPCoreTM, providing the processing power required to support. The latest OpenOS and its demanding applications such as web browsing, email, GPS navigation and gaming.
