Intel at its second Developer Forum keynote officially unveiled its first Core i7 processors for notebooks. Once codenamed Clarksfield, the quad-core processors share the same Nehalem architecture and 45 nanometer process as the desktop part but are designed to consume much less power, although more at peak than the Core 2 Quad. The top-end Core i7 Extreme consumes 55W where regular quad Core i7 mobile chips will use 45W.
