Latest AMD chip launched

US microprocessor maker AMD launched its latest quad-core processors in Beijing yesterday, the first stop of its global launches.

The quad-core Opteron processor claims to be the world's most advanced computer chip with a performance 50 percent higher than the current dual-core products.

Its arch-rival Intel launched a similar quad-core product last week, but AMD claims its product is the only one with four cores in the same semiconductor die.
