Intel will update its Centrino laptop package in January with a new processor and better graphics.
The update, called Santa Rosa Refresh, will replace Centrino's current processors with chips made using a 45-nanometre production process - part of Intel's Penryn chip family - instead of the 65nm process currently in use. The number refers to the average feature size that can be created on a chip and smaller is generally better.
Moving to a more advanced manufacturing process typically results in faster chips that consume less power. It also allows chip makers to reduce the size of the chip, either cutting unit production costs since more chips can be made on a silicon wafer, or allowing new capabilities, such as a larger memory cache, to be added to the chip.
The Santa Rosa Refresh will also include the 965 Express chipset and support for Microsoft's DirectX 10.0 technology.
This updated version of Centrino will itself be replaced in the middle of 2008 with a new version, called Montevina. This version of Centrino will also use a 45-nm processor but includes a new chipset that offers support for faster DDR3 (double data rate 3) memory.
Montevina will also WiMax as an option, in addition to Centrino's customary Wi-Fi support.
