Jan 25 (Reuters) - Intel forecast quarterly revenue below market estimates on Thursday as it grapples with uncertain demand for its chips used in the traditional server and personal computer markets.

The Santa Clara, California-based company expects adjusted first-quarter revenue in the range of $12.2 billion-$13.2 billion, compared to analysts' average estimate of $14.50 billion, according to LSEG data.
