NEW YORK (AP) — Intel’s earnings fell in the first three months of the year amid a continued slump in the worldwide PC market, but revenue grew slightly because of solid demand for tablet processors and its data center services.

Intel Corp. is the world’s largest maker of microprocessors, which act as the “brains” of computers. Intel has historically been strong in selling chips for personal computers, but that business is declining as people buy smartphones and tablets instead. Intel has been slow to respond to that shift with lower-energy chips that mobile devices demand.
