Details of The war of nanometers 4

Colossus Intel and IBM, in the past days have revealed new details on the respective technologies to 45 nanometers. Both, will be taken advantage of new materials to use in substitution of those employ give to you beyond 30 years. The production of chip of 45 nm will have the effect to reduce the dispersion of current, the absorbed energy and the generation of heat in the transistors.

Intel and IBM utilizeranno of the gate transistors with metallic, in place of those in polisilicio, and a new insulating material, with property "high-k" (to high constant k, ingrado that is to withhold a greater number of loaded electrical workers), in substitution of silicon dioxide. For the moment, the identity of the new material remains secret high-k, that it will come employed in order to control the flow of the current electrical worker. Being to how much declaring from Intel, its new material high-k will reduce of beyond 100 times the current dispersion.

The first prototype of the Intel to 45 nm, "Penryn" (will contain approximately 200 million transistor for every Core and will include the new one with of extend instructions SSE4), will be to the base of the next generation of processori Core 2 and Xeon dedicates to you to serveur, desktop and notebook. The next generation of CPU will reach therefore until 12 MB of cache and will push the clock beyond the 3 Ghz.

The launch on the market of Penryn is previewed for the second half of 2007, while for the new platform "Montevina" it will have to wait for the beginning of 2008.

As far as IBM, instead, first processori AMD to 45 nm, that they will use the litografia to immersion, would have to arrive around to the half of 2008. Between the partner of Big Blue in the development of the new technologies of production of the chip they figure also Sony and Toshiba, Co-sviluppatrici of the processore Cell, employee in Playstation 3.
