THE United States semiconductor manufacturer Intel Corp grew more than 26 per cent last year to retake the position as the world's largest computer chip maker, according to figures released by research firm Dataquest. Intel climbed from being the third biggest semiconductor company last year behind Japan's NEC and Toshiba to take the top position. Intel increased revenue during 1992 by more than US$1 billion to $5.1 billion. Another US company, Motorola, also had an exceptional year, according to Dataquest, growing more than 22 per cent over last year and adding $833 million to its revenue. The Dataquest figures point to a resurgence in the US semiconductor industry. The worldwide market for semiconductors grew by nearly 10 per cent for the year. But according to the figures, the Asian market grew an astonishing 29 per cent during 1992 - the third year in a row of rapid growth. In a separate survey released last week, Dataquest found that IBM remained the number one global PC supplier, despite losing a significant market share last year. The figures revealed IBM held 12.4 per cent of the world market last year, down from 16.4 per cent. Apple Computer, the number two supplier commanded 11.9 per cent of the market, compared to 11.2 per cent a year earlier. Compaq was the third largest PC supplier, followed by NEC and Dell. Overall, the PC market grew from $43.4 billion in 1991 to $46.5 billion in 1992.
