Llano, the first Fusion chip, will have about a billion transistors and be manufactured on a 32-nanometer process, Bergman said. For comparison, AMD's current Phenom II processor has 758 million transistors and is made with a 45-nanometer process.

Llano will appear in mainstream laptops in 2011 as part of a platform called Sabine, which will have four CPU cores and support DDR3 memory and DirectX 11 graphics, Bergman said.

For mainstream desktops, Llano will appear at about the same time in a platform called Lynx, which will also support DDR3 memory and include up to four CPU cores.

AMD also discussed two new x86 architectures it is developing -- Bulldozer, for larger and more powerful chips that will go in servers, desktops and laptops, and Bobcat, which is designed to use less power for ultrathin laptops and netbooks.

Bulldozer will appear first in 2011 as part of the Scorpius platform for high-end enthusiast desktops. It will be offered in four- and eight-core versions and be coupled with DDR3 memory and a discrete graphics chip. A dual-core Bobcat processor will also come in 2011, as part of a platform called Brazos, which will include a Fusion chip known as Ontario.
