Why Tech Giants Are Racing to Build Their Own Chips – The New Semiconductor Arms Race

After its education business faltered, ByteDance turned its attention to chip development, announcing in March that it is creating a cloud‑AI chip and an Arm‑based server chip while confirming the formation of a dedicated chip team.

In July, ByteDance poached three chip‑related talents from Baidu by offering higher compensation, and insiders note that Baidu’s independent Kunlun chip division now has about a hundred engineers, suggesting ByteDance’s team could soon surpass it.

At the same time, Tencent has been hiring for chip positions, focusing on specialized accelerators for AI and video codec tasks rather than general‑purpose processors.

Most major Chinese internet firms—Huawei, Alibaba, Baidu, Xiaomi, and others—have long been developing their own silicon, covering both smartphone manufacturers and cloud service providers.

In the short term, self‑designed chips help companies mitigate the global chip shortage, while in the long term the industry is entering a golden age of architectural innovation, with heterogeneous computing that combines Arm CPUs, NPUs, GPUs, and specialized accelerators.

Arm’s architecture has rapidly advanced, now rivaling Intel’s x86 in performance, and the availability of sub‑5 nm processes from TSMC enables firms to design powerful custom chips without owning fabs.

Smartphone makers such as Huawei (with HiSilicon Kirin), Xiaomi (with ISP chip Pengpai C1), OPPO, and Vivo are developing SoCs or dedicated co‑processors to enhance imaging and AI capabilities, while earlier attempts like Xiaomi’s Pengpai S1 highlighted the challenges of SoC design.

Cloud providers are also focusing on AI chips: Baidu’s Kunlun series, Alibaba’s Pingtouge products, and ByteDance’s announced AI chip all aim to differentiate their services.

Founder Zhang Yiming once said that as a company grows stronger it must move toward the underlying infrastructure, a vision now being realized through initiatives like Volcano Engine, ByteDance Cloud, and AI chip development.

Arm’s dominance in global compute—now powering over 95 % of smartphones and projected to support a trillion IoT devices by 2035—reduces reliance on Western technology and reshapes the semiconductor landscape.

Intel, long the leader in x86 CPUs, faces mounting pressure from Arm‑based solutions and emerging Chinese competitors, leading to a sharp market‑cap decline and a new CEO appointment.

Nvidia’s attempted $400 billion acquisition of Arm has sparked regulatory scrutiny and industry opposition, highlighting the strategic importance of Arm’s IP for future AI‑IoT markets.

Overall, the accelerating “chip‑making” wave among tech giants reflects a broader shift toward digital sovereignty, diversified architectures, and intensified competition in both mobile and cloud computing arenas.
