AMD has introduced its Turion line of 64-bit mobile processors, and announced several notebook makers have new systems based on the chips.

There will be seven Turion 64 models - the ML-37, ML-34, ML-32, ML-30, MT-34, MT-32, and MT-30 - working to a new naming system. The first two letters identify the chips as Turion mobile chips, and the second letter indicates power consumption (the further down the alphabet, the lower the power consumption, the longer the battery life).

Several vendors, including Fujitsu-Siemens, Acer, Asustek and BenQ plan to introduce in the coming months notebooks based on the new chip. However, leading PC makers Dell, HP and IBM are notably missing.

The Turion 64 ML-37, ML-34, ML-32, ML-30, MT-34, MT-32, and MT-30 chips are available immediately, AMD said. They are priced at US$354, $263, $220, $184, $268, $225 and $189, respectively, in 1,000-unit quantities.
