The chipmaker also listed its first mobile quad-core processor, the QX9300, which runs at 2.53GHz and comes with 12MB of level-2 cache. The processor is priced at $1,038.

The 45-nanometer low-power processors will go into ultra-portable notebooks like the new ThinkPad X301 announced this week, and HP 2530p also rolled out on Monday. The next version of the MacBook Air is also rumored to be using one of these chips.

The SL9400 and SL9300 processors have a thermal envelope of 17 watts, about one half the power envelope of mainstream Intel mobile processors rated at 35 watts. The SL9400 runs at 1.86GHz and is priced at $316. The SL9300 is clocked at 1.6GHz and priced at $284. Both chips have 6MB of cache memory.

Further down the power scale, the SU9400 and SU9300 are rated at only 10 watts and have clock speeds of 1.4GHz and 1.2GHz, respectively. The SU9400 is set at $289, while the SU9300 goes for $262. Both have 3MB of cache memory.

Intel also announced new mobile Celeron models. The mobile Celeron 585 has a core clock speed of 2.66GHz and is priced at $107. The 575 model runs at 2GHz and sells for $86.
