INTEL Corp, the world's largest computer chip maker, last week announced record revenue and earnings for the first quarter of 1993, the company's first US$2 billion quarter. First quarter revenue increased by 63 per cent from the corresponding quarter last year, while net income grew 198 per cent. Revenue for the quarter ended on March 27, totalled US$2.02 billion, against $1.24 billion one year ago. Net income amounted to $548 million, or $2.48 per share, compared with $184 million or $0.86 per share in last year's first quarter. In the fourth quarter of 1992, Intel recorded revenue of US$1.86 billion and net income of US$1.97 per share. ''It took us 22 years to get to US$1 billion a quarter in revenues and, thanks to the explosion in demand for the Intel 486 chip, less than three years to get to US$2 billion a quarter,'' said Mr Andrew Grove, president and chief executive officer. Production shipments of the new fifth generation Pentium processor began in March. The Pentium chip maintains compatibility with more than $50 billion worth of available software and is more than 300 times faster than the 8088 used in the original IBM PC.
