The sector grew by 31% year-on-year for the quarter while 5G smartphone shipments grew by a factor of four year-on-year.
Counterpoint research director Dale Gai said: “MediaTek dominated the smartphone SoC market with its highest ever share of 43%, driven by a competitive 5G portfolio in the low-mid segment and without major supply constraints. Last year, the Taiwan firm took 26% of the market.
"Relative to Qualcomm, MediaTek benefitted from less supply constraints in the first half of 2021, including with RFICs (radio-frequency integrated circuits), power management ICs (PMIC), and stable production yields from TSMC. 4G SoC shipments further helped MediaTek to strengthen its leading position.”
Commenting on the growth of 5G smartphone baseband shipments, research analyst Parv Sharma said: “Qualcomm dominated the 5G baseband market with 55% share. It gained from the 5G baseband modem chipset win in the Apple iPhone 12 series and the significant demand for its complete 5G SoC chipsets, from the flagship 8 series to affordable 4 series.
"However, Qualcomm would have shipped more chipsets if the San Diego vendor wouldn’t have been affected by the supply-side constraints and yield issues during the first half of 2021.
"As a result, Qualcomm diversified and secured extra capacity starting at TSMC and other foundries for various components in late Q2 2021. This should help the vendor streamline its component supply and regain the share lost to MediaTek in the coming quarters.”
