Intel has revealed details of its 45 nanometre technology which will form part of its next-generation Core 2 and Xeon processors. Adhering to Moore's Law, the new Intel technology with High-K and Metal Gate materials for the transistors has allowed the chip giant to build working samples of 45nm processors already.
As per Intel documents, compared to today’s 65 nm technology, the 45 nm technology will provide the following product benefits:
* Approximately twice the in transistor density, for either smaller chip size or increased transistor count
* Around 30% reduction in transistor switching power
* A fifth improvement in transistor switching speed or more than 5x reduction in source-drain leakage power
* More than ten times reduction in gate oxide leakage power
The Penryn family of processors will have 410 million transistors for the dual core variants and twice that for the quad-core models according to Intel. Much of the increased transistor count will be used for larger caches, but Intel would not reveal the exact size at the media briefing.
Higher clock frequencies are on the cards for Penryn as well but again, no word as to what speed the processors will launch at was given, nor was there much detail on the new microarchitecture features that Intel promises will hike performance. However, SSE 4 instructions will come alive with Penryn, aimed at making media and HPC applications run faster.
The quad-core Penryns will follow the same design of the existing Core processors, in that they will be dual-core parts joined together in a silicon foursome. Penryn will be available commercially in the second half of the year, according to Intel.
