As expected, Intel just announced its Clarksfield laptop chips, bringing Core i7 to the laptop form factor. There'll be three chips, two regular quad-cores and a Core i7 Extreme that can run as fast as 3.2GHz in Turbo mode, which selectively shuts off cores and uses the extra power to speed up the remaining cores while preserving battery life. The parts were demoed working in shipping-ready form on stage, but pricing and availability weren't mentioned -- we'll let you know what we can dig up.
