Shares in the US company Intel have surged after the worlds biggest chipmaker's profit rose by nearly a third in the first three months of the year.
The company's profit rose 29% to $US3.2 billion in the quarter, defying fears the world's top chip maker is struggling to find its footing as personal computer sales growth wanes.
Sales jumped a quarter to nearly 13 billion.
Intel chief financial officer Stacy Smith says he expects new products to further boost growth.
