Intel lost CPU revenue share to AMD last quarter

Last month, we saw preliminary Mercury Research numbers that said AMD's share of x86 microprocessor shipments had grown substantially last quarter. What about AMD's slice of global microprocessor revenue? Rival market research firm iSuppli has now released revenue share numbers for the first quarter, and they, too, show gains on AMD's part.

According to iSuppli, Intel's share of revenue across the entire microprocessor market (which includes non-x86 CPUs) fell from 81.6% in the fourth quarter of last year to 79.1% in the first quarter of 2009. Over the same time period, AMD's revenue share climbed from 10.5% to 12.8%.
