Qualcomm (NASDAQ:QCOM) delivered decent quarterly results during its latest earnings call, managing to grow both its top-and bottom lines in high single digits. Investors were, however, spooked when the company cut its full-year revenue and profit forecasts - the second time it did this. Qualcomm pinned the lower expected sales of the company's Snapdragon chips on a significant loss of design sockets in Samsung's (OTC:SSNLF) Galaxy S6 and Note. Qualcomm currently leads the modem market and makes most of its money selling baseband chips. Qualcomm has also been facing a lot of competitive pressure lately from MediaTek, the giant Taiwanese chip manufacturer. UBS analysts recently notedthat Qualcomm was likely to lose 4G market share in China to MediaTek due to the latter's superior chip technology. According to the analysts, MediaTek could see its 4G market share in China shoot up to 46% in the current year from 30% last year - at Qualcomm's expense. It appears as if Qualcomm has been using Taiwan Semiconductor (NYSE:TSM) 28LPM, or Lower Performance Mobile, technology in a bid to cut costs. In comparison, MediaTek has been using TSM's 28HPM, or High Performance Mobile, technology hence the difference in chip performance. According to Qualcomm, Moore's Law stopped being cost-economic around the 28nm node, which might explain why it has been using cheaper fabrication processes for its mobile chips as node technology advances.
