MediaTek's 5G processor "Dimensity" features power saving and low latency, what is the deployment in Japan? (1/2 page)

On July 21st, MediaTek will hold an online briefing on its latest 5G solution developments and initiatives. He explained the 5G processors "Dimensity 1000+" and "Dimensity 800 series" along with the latest situation in the Japanese market.

First, Ken Izushi, Acting Business Development Director of MediaTek Japan, talked about MediaTek and Japan. I explained the market situation.

MediaTek is a Taiwanese fabless semiconductor manufacturer headquartered in Hsinchu, Taiwan. It ranks 4th in the industry among fabless semiconductor manufacturers and 13th in the industry as a whole among semiconductor manufacturers, with sales of approximately 800 billion yen in fiscal 2019. It has 50 locations in 35 cities and employs more than 16,000 people.

Since its founding, the company has been working on processors for home appliances such as BD/DVD and TVs. In addition, we handle an extremely wide range of products, including communication devices such as smartphones, tablets, and access points, game consoles, automotive products, AR/VR products, and processors for data center devices. It says it is shipping. MediaTek boasts the top share of the industry in major segments other than smartphones, and it is said that about one-third of the mobile phones in the world are equipped with MediaTek processors.

MediaTek Japan, a Japanese subsidiary, is a wholly owned subsidiary of MediaTek Inc. and was established in 2007. Currently, there are about 25 staff members. "The Japanese market is mature and sufficiently large, and there are many global brand manufacturers. We believe that the Japanese market has been and will continue to be an important market for MediaTek." (Mr. Izushi)

The market share of TV processors is No. 1 in the world, and of course MediaTek's processors are also used in the products of Japanese manufacturers. Smartphones sold in Japan use MediaTek, such as Kyocera's "BASIO 4" handled by au, Y!mobile's "Android One S6", and Samsung Den's "Galaxy A41".

MediaTek has a deep relationship with Japan. On July 27, 2010, a license agreement was signed for the LTE-compatible communication platform "LTE-PF" developed by four companies including NTT DoCoMo.

LTE-PF is still used in MediaTek's smartphone processors. While Japanese semiconductor manufacturers are withdrawing from the modem business, ``It can be said that the crystallization of LTE knowledge of Japanese companies continues to live only in the processor of MediaTek, the only other company besides Docomo. MediaTek is a Taiwanese company, but the product I want to convey that there is Japanese blood in it." (Mr. Izushi)

MediaTek's latest 5G solution was explained by Dr. Yanchi Lee, Deputy General Manager of Wireless Communications Business Unit, and Nathan Lee, Senior Director of the same unit.

MediaTek has been investing in 5G solutions for several years. In 2018, the first 5G modem processor "Helio M70" was announced. In 2019, we accelerated development while collaborating with many RF vendors, and we are conducting the world's first multi-vendor 5G NR standalone data communication test with T-Mobile in the United States. In November 2019, it announced the Dimensity 1000 as a 5G processor.

Since the beginning of 2020, in addition to joint VoNR voice and video call tests with OPPO and Ericsson, we have also collaborated with Vodafone, Ericsson, and OPPO to demonstrate network slicing on a 5G standalone network in the UK. did

In January 2020, we announced the Dimensity 800 series of 5G compatible processors for the middle range, which is the second stage of the Dimensity series.

The Dimensity 1000+ introduced here is MediaTek's first 5G processor, Dimensity Improved version of 1000. Developed on the 7nm process, it is a processor used in high-end smartphones. Adopting the "big.LITTLE" architecture, all big core Cortex-A77s are driven at a high speed of 2.6 GHz. It is said that it is highly energy efficient and at the same time realizes power saving.

The Dimensity 1000+ GPU uses nine of the latest "Mali-G77". Compared to the previous generation G76, the energy efficiency is improved by 30%. In addition, "I can't talk about flagship mobile phones without AI" (Mr. Nathan), and the AI ​​processor (APU) "MediaTek APU3.0" is installed. This APU3.0 is ranked first in the famous AI benchmark ranking, showing confidence that it will deliver excellent performance.

Modem: NSA/SA (non-standalone/standalone), 5G Equipped with the most advanced "MediaTek 5G UltraSave" in 5G modems, such as supporting 2CC CA (2-wave carrier aggregation) and DSDS (dual SIM dual standby).

On the other hand, the corresponding frequency is limited to Sub-6 below the 6 GHz band, and does not support millimeter waves. The ISP is equipped with the flagship-level "Imagiq", enabling 80-megapixel single camera, 32-megapixel + 16-megapixel dual camera, and 4K video recording at 60fps. In addition, Dimensity 1000+ will support a display with a refresh rate of 144Hz and HDR10+.

In addition, it supports Wi-Fi 6 and realizes low latency and high response operation with "MediaTek HyperEngine 2.0".

Dimensity 800 and 820 are 5G compatible processors targeting mid-range to mid-high smartphones. The CPU is equipped with four Cortex-A76s driven by 2.6 GHz on the big core. It is said to achieve performance close to the flagship smartphone of the previous generation.
