Intel has lowered its PCs sales forecast for the third quarter of 2010, citing factors such as weaker than expected demand for consumer PCs, particularly at the mature markets.

Intel expects its revenues to be at the lower end of, or slightly below, its previously expected range at $11.0bn, plus or minus $200m, compared to the previous expectation of between $11.2bn to $12.0bn.

For the third quarter, the company expects gross margin to be 66%, plus or minus a point, compared to previous estimation of 67%.

The marginal difference is due to lower volume is being partially offset by slightly higher average selling prices stemming from solid enterprise demand, the company said.

Equity Investments, interest and other are expected to be $175m, consistent with the company’s revised expectation reported on Form 8-K filed 16 July.
