Currently some 70 percent of Intel’s entry desktop segment sales are Atom single-core 200 and Celeron 400 series CPUs, while Atom dual-cores and Celeron dual-cores control some 30 percent combined. Atom single-core market share in Q1 was less than 5 percent, while Celeron single-core 400 series 65nm had some 65 percent.

Dual-core Celeron holds some 23 percent of this market in Q1 2009, while Atom dual-core 300 series has some 7 percent of the market.

In Q2 2009 Atom 300 series dual-core will jump to more than 25 percent of this market, at the expense of Intel Celeron single-core 400 series 65nm than will drop to less than 50 percent.

In Q3, Celeron single core 65nm 400 series will further drop to some 21 percent, while in Q4 2009 its market share will shrink to some 18 to 19 percent of this market. So despite what Intel is saying, Atom is not creating a new desktop market niche, it is, in fact, eating Celeron's market share. Of course, these numbers are Intel's hopes, plans and predictions for quarters to come.
