AMD is to supply dual-core chips for laptop PCs with the appearance of its Turion 64 X2 processors.
Turion was already being supplied to notebook manufacturers but the processor now comes with a dual-core version to boost processing speeds for users.
Dual-core chips have two processors on a single piece of silicon to achieve the faster speeds.
HP, Gateway and Acer are among the first laptop PC manufacturers who say they will be including the Turion 64 X2 processors in their machines over the next few weeks.
The move by AMD will put even more pressure on much bigger rival Intel, which has already lost some market share to AMD in the desktop and server market segments.
Up until now, Intel had held a performance advantage over AMD in the laptop market.
In August however, Intel plans to ship a notebook version of the Core 2 Duo dual-core processor, formerly known as Merom.
This chip will outperform and consume less power than Intel’s existing Core Duo chip.
