A sales slump in computers combined with the rise of netbooks has the industry awash in chips, mostly of the Intel variety. Intel lost 4.7 percentage points of marketshare to rival

in the first quarter as overall industry processor shipments fell 10.9% from the December quarter, according to a report from IDC released Tuesday.

The news comes on the same day that Intel hosts its annual analysts' day show, which is expected to include an update on inventories at the No. 1 computer processor maker.

Though it is Intel's show, netbooks will take center stage.

The $300 mini-laptops have become the symbol of the consumer electronics recession. Not only have cheaper devices been a hit with bargain hunters, but they also have bruised the giants of the PC industry like Intel,

The big problem for Intel is that the Atom processors it supplies to netbook makers sell for far less than its dual core processors used in larger notebooks and desktops. Intel has to convince analysts that there's more than revenue erosion ahead in an increasingly netbook driven industry.

"I expect they will talk about how they are managing the notebook product lines," says TBR analyst John Spooner. "They'll insist that they aren't risking their profitability by selling lower-end processors."

To help them sell that message, Spooner expects to hear a lot from Intel about a new chip, its consumer ultra low voltage or CULV processor for mid-range notebooks.

Investors looking for an all-clear sign from Intel may have to wait. IDC concluded in its report that is sees a modest sequential decline in processor shipments in the second quarter.

You can probably expect Intel to emphasize improved prospects in, ah, the second half of the year.
