Further pitting itself against Intel's Pentium-M offerings, AMD on Monday expanded its line-up of mobile Athlon 64-bit processors to include the new Mobile AMD Athlon 64 processor 3000+, operating at 2GHz.

The new processor is meant for use in thin and lightweight notebook computers. It is the highest performing processor in AMD's family of low-power Mobile AMD Athlon 64 products, which already includes 2700+ and 2800+ versions, according to the AMD Web site.

Acer is the first computer maker to announce support for the new AMD processor. Acer plans to start selling a notebook in its Ferrari line equipped with the Mobile AMD Athlon 64 processor 3000+ in Europe later this month and worldwide by the end of October, according to AMD.

AMD offers three Athlon 64-bit processor types for mobile use. The low-power version of the Mobile Athlon 64 offers is meant for use in light and thin notebooks, the mainstream Mobile Athlon 64 offers higher performance for use in full-size notebooks and the Desktop Replacement AMD Athlon 64 processors are the highest performing processors for powerful notebooks.
