Intel has already set foot on the 32 nm lithography, with first 32 nm based prcoessors expected to arrive in Q1 2010. These processors have already been extensively sampled, and tested by sections of the media. More importantly, 32 nm marks Intel's introduction of the
Westmere architecture, which is a 32 nm optical shrink of Nehalem, with a slightly expanded feature-set making use of the possibly higher transistor loads. Starting with dual-core "Clarkale" processor, Intel plans to work out high-end six-core processors codenamed "Gulftown" within the first half of 2010. In addition to this, Intel is readying Westmere's successor, codenamed "Sandy Bridge".
While a vague die-shot of a supposedly mainstream quad-core processor based on Sandy Bridge
surfaced last month, more information about it is coming to light from industry sources, according to DigiTimes. Intel will introduce the Sandy Bridge architecture in the fourth quarter of 2010. Considering the first Westmere CPUs are commercially launched ten months after its formal introduction (Westmere was unveiled in February,) the commercial launch of the first Sandy Bridge processors can't be too far away from Q4 2010. This in essence shows that Intel can afford to come up with a new flavour of CPUs every year. Nehalem will have served as a 1.25 year "tock" for the 45 nm process, while Westmere may serve as a "tick" of nearly the same length. For those of you unfamiliar with Intel's "tick-tock" model of product development cycle, The company uses a "tick-tock" model of process development, where each processor architecture gets to be made in two manufacturing processes, while each process gets to build two succeeding architectures.
