By the fourth quarter of this year, AMD and ATI will jointly launch a new notebook platform codenamed Yokohama, directly competing Intel's current Napa64 platform, according to media reports.

Citing Taiwanese industry sources, DigiTimes.co mreports that the platform will be based on AMD's Turion 64 X2 processors and ATI's future chipsets, which are currently known as the RS690M, RS690DC and RS790M.

"Targeted to compete with Intel's Napa Refresh platform, the Yokohama platform may also include WLAN chipsets from Broadcom, Atheros Communications or Airgo Networks," the sources added.

Using ATI's chipset solutions, AMD will likely build its own Centrino-like platform for high-performance laptops.

Next year Intel is expected to release "Santa Rosa," the successor of Napa64, which is expecte to offer a series of performance enhancements, such as an increase in bus speed, support of flash cache as well as an improved wireless chipset.
