Next On AMD's Roadmap: Turion, Athlon, Sempron Mobile Chips

AMD is gearing up for its spring-summer collection of mobile processors, and the latest leaked company roadmap illustrates a completely new mobile processor portfolio, that will be introduced in the second half of the year. The upcoming notebook offerings include four processors based on the Griffin silicon. Both the Turion and Athlon mobile CPUs in the next generation will bear the "Lion" codename.

The Griffin codename covers the laptop processors that will power AMD's first fully-mobile Puma platform. The company's roadmap details about AMD Turion 64 Ultra and AMD Turion 64 dual core models, that will arrive on the market with 2MB and 1MB of L2 cache respectively. The chips will also feature support for DDR2-800 memory only, and will work at frequencies of between 2GHz to 2.4GHz. The Turions will feature a thermal envelope of 32-35 watts, depending on their clock speed.

Next on the company's roadmap there is the single-cored Athlon 64 mobile processor that will come with 1MB of L2 cache, DDR2 memory at up to 667MHz and core clock frequencies of at least 1.9GHz. The Athlon 64 mobile chips will feature a thermal design power of about 31 Watts.

Advanced Micro Devices has also detailed upon the AMD Sempron in the "Sable" family, that is basically a stripped-down version of the "Griffin" silicon. It will come as a single-core offering, featuring 512KB of L2 cache, clock speeds starting from 2GHz, neatly packed in a 25-watt thermal envelope.

The "Griffin" silicon has been built from the ground up for mobile computers, and that is why chips built on it are famous for the power optimization technology.

Most of the announced chips will enter mass-production in April, but the usual delays will probably shift it to May. AMD has already announced that the first Puma-based notebook computers will start shipping in the late second quarter of the year.
