Last week, China’s Ministry of Industry and Information Technology issued 5G licenses to China Mobile, China Telecom, China Unicom and the broadcasting and television network. This means that China’s 5G is officially commercialized. There is no doubt that China will build the world’s largest 5G communication network in the next few years.
5G licensing is also a big event for the smartphone industry, which will greatly promote the development of 5G phones. But 5G phones need 5G chips. Currently, Qualcomm, Huawei, Samsung, Intel, MediaTek, and Spreadtrum have launched their 5G baseband chips. However, the current 5G baseband is external, mainly due to the large scale of the 5G baseband chip, which is temporarily not suitable for integration into the processor.
At today’s MediaTek General Meeting of Shareholders, a representative asked why MediaTek came later than other manufacturers on the 5G SoC chip. The chairman of MediaTek, Cai Mingjie, immediately clarified this misunderstanding. He said that MediaTek is the first company in the world to release a 5G SoC.
MediaTek Helio M70 Chip
On May 29, MediaTek announced the launch of a multimode 5G SoC chip with a 7nm process and built-in Helio M70 modem independently developed by the company. It uses an energy-saving package. This design is superior to the external 5G baseband chip solution and can be used with lower power and achieve higher transfer rates.
The 5G SoC has a 4.7Gbps download speed and 2.5Gbps upload speed. Applicable to 5G independent and non-independent (SA / NSA) networking architecture Sub-6GHz frequency band, supporting 2G to 4G generation connection technology, it uses dynamic bandwidth switching technology. Moreover, it can allocate the required 5G bandwidth for specific applications. Thus modem power performance is increased by 50%, extending the end battery life.
MediaTek’s multimode 5G SoC uses the latest Arm Cortex-A77 CPU and Arm Mali-G77 GPU released by ARM on Monday. ARM said the Cortex-A77’s IPC performance has been increased by 20% compared to the Cortex-A76. In machine learning, the Cortex-A77 performs 35 times better than the Cortex-A55 due to the collaborative optimization of hardware and software.
The Mali-G77 GPU uses the latest Valhall architecture (which has been released with the previous generation of Bifronst for three years) with 40% performance improvement, 30% performance density increase and 60% machine performance improvement.
