AMD has released the first dual-core processors in its 64-bit processor range.
The company said that its Athlon 64 X2, designed for desktops and some notebooks, could deliver performance enhancements of up to 80 per cent over single-core processors.
Lenovo, Acer and HP have all signed up to use the latest chip, along with 40 other system builders.
The X2 chip will significantly improve multi-tasking for desktop users, according to Bob Brewer, corporate vice president of the desktop business at AMD.
AMD added that it is hoping to steal customers from Intel, which uses the same 939-pin motherboard slots as AMD's single-core chips. In contrast, Intel's dual-core architecture requires new boards.
Both processor firms are committed to dual-core and multi-core for all types of processor, but AMD has been faster to market.
The company has also scorned Intel's targets for product releases, maintaining that it is now ahead of Intel in certain areas.
