Shenzhen's chip design is more powerful, and it should be the best in China. However, as far as the industrial chain is concerned, the actual chip industrial chain production is mainly in Shanghai and around Shanghai. In addition, Shenzhen's chip market is relatively large, because most of the domestic smart phone brands are in or around Shenzhen, so Shenzhen has a great influence in the domestic chip market.
Shenzhen is also the most developed city in the field of information technology in China. Huawei, Lenovo, ZTE, Tencent and others are headquartered in Shenzhen, especially Huawei. Huawei's chip design is top in China, but there is no industrial chain of chip production. In the visible future, Shenzhen's chips are still leading in the country and can be compared with Shanghai.
