Intel posted a Twitter update this afternoon, which promised the 4th Generation Intel Core Processor will arrive in 3,337,200,000,000,000 nanoseconds.
According to Wolfram Alpha, that means the processors will drop on Monday 3 June - a day ahead of the official opening of Computex. Indeed, some sources are reporting the launch date will be 4 June.
Haswell is the successor to Ivy Bridge. Ideal for Ultrabooks because it's designed to offer significant power savings, Haswell is a new architecture that will be built on the same 22nm process as Ivy Bridge.
Speaking at the Intel Developer Forum in Bejing, Kirk Skaugen, general manager of the PC client group at Intel, said Haswell would feature double the graphics performance of Ivy Bridge, claiming it offered "the same visual experience and gameplay as a discrete graphics card that users would otherwise have to add separately".
At CES in January, Intel updated the specs list for the next generation of Ultrabooks, which will run Haswell, requiring them to have touchscreens and support Intel's WiDi wireless display system.
Intel also showed off its next-gen Atom processors for microservers, called Avoton, saying it was already shipping samples to customers for testing, and unveiled its data centre chips based on the 22nm process.
