In second half of 2013
Ivy Bridge 22nm entered production in the first half of 2012, weeks ahead of launch, and at this point Sandy Bridge was accounting for some 70 percent of the market. Ivy Bridge was represented by less than five percent of total Intel market for desktop CPUs in Q1 2012.
Already in the second half of 2012 Ivy Bridge market presence climbed to around 30 percent taking most of the market share from Sandy Bridge, a previous generation 32nm that is in sharp decline. Still Sandy Bridge takes almost 50 percent of the whole market even in second half of 2012.
In the first half of 2013 it is expected that Ivy Bridge will take more than 70 percent of the market, leaving Sandy Bridge at some 10 percent of market share and Atom fixed at some 5 percent of market.
Let’s not forget that a few percent, probably close to 2 percent will always belong to Sandy Bridge E high end parts.
In the second half of 2013 Sandy Bridge will almost completely vanish while Ivy Bridge will remain at 60 to 70 percent, but Haswell will start its ramp to dominance that is expected in 1H 2014.
