Intel reduced prices of its desktop Celeron microprocessors by up to 13 percent on Sunday.

Pricing for mobile Celerons and other Intel microprocessors remained unchanged.

The price of the 1.2GHz desktop Celeron dropped 13 percent from $79 to $69, according to a notice on Intel's price list website. The price of the 1.3GHz model fell 12 percent, from $84 to $74.

At the bottom of the range, Intel lowered the price of the 1.1GHz model by seven percent from $69 to $64, the same price as the 1GHz version, which remained unchanged.

All of the models in Intel's current desktop Celeron range have 256KB of cache memory and are built using its 130-nanometer (0.13-micron) production technology.

Prices are for direct Intel customers less tax and shipping, but the price chop should filter through to new units quickly.
