AMD attempts to derail Intel's Santa Rosa

Less than a week before the next version of Intel's Centrino is due to be officially announced, AMD has released details of its own mobile platform which promises a 25 per cent increase in battery life.

Less than a week before the next version of Intel's Centrino is due to be officially announced, AMD has released details of its own mobile platform which promises a 25 per cent increase in battery life.

AMD has announced further news of its M690 chipset -- previewed last month -- which includes features similar to Intel's own "Santa Rosa" platform such as support for draft-N wireless, reduced-size 65nm processors, and solid-state memory caching.

To extend battery life, M690 will incorporate memory technology known as display cache, which will allow the company's 65nm Turion dual-core CPUs to operate in low-power mode without accessing system memory.

The company says it expects these technologies to increase the average battery life of AMD-based portable systems from four hours to five as a result.

Despite merging with graphics company ATI, AMD's new chipset will predominantly feature a graphics solution supplied by competitor NVIDIA.

"AMD-based systems with NVIDIA graphics deliver an outstanding Windows Vista experience and powerful digital media capabilities." said Ned Finkle, vice president of strategic marketing at NVIDIA in a press release.

AMD expects notebooks based on the M690 chipset will be available in the US as soon as next month, but no official announcement has been made as to Australian availability.

Meanwhile, laptops based on the business version of Santa Rosa, Centrino Pro, are due to arrive in Australia from the middle of May. The consumer range, expected to be called Centrino Duo, will start to appear in June.
