Intel will increase its market share by the end of 2007 to 12.5 percent, keeping its place as the world's top chipmaker, while rival AMD will drop out of the top 10, research firm iSuppli predicted.

Samsung will remain the world's second-biggest chipmaker with 7.4 percent of the market while Toshiba will rise to third place, pushing Texas Instruments to number four, iSuppli said.

Intel managed to keep the first place on the market share mainly due to the success of its lines of dual- and quad-core chips. After rising into the top-10 rankings for the first time ever last year, AMD's revenue decline is expected to cause it to drop back to 11th place in 2007, down from eighth place in 2006.

Sony is seen leaping into eighth place from 14th in 2006 with a 57 percent increase in revenue, thanks to sales of chips for its PlayStation 3 games console.

Infineon was expected to benefit from a booming market in mobile phones to rise to 10th place from 15th, thanks to its own strengthening wireless business.
