Intel has launched four mobile Pentium 4 and Celeron processors aimed at the laptop market.
Three of the new processors, the 518, 532 and 538, are in the Pentium 4 Mobile family and run at 2.8GHz, 3.06GHz and 3.2GHz respectively.
All are based on Intel's 90 nanometre architecture which allows more transistors to be packed onto each chip, reducing power use and heat generation.
Intel's latest mobile chips use hyperthreading and SpeedStep technology originally used in desktop systems to boost performance and cut power requirements.
A new Celeron mobile processor, called the 340 and running at 1.5GHz, is aimed at the budget and ultra-portable laptop sectors, as it does not require a bulky heat sink.
In 1,000 unit quantities, the 538, 532 and 518 are priced at $202, $234 and $294 respectively. The Celeron M 340 is priced at $134 in the same quantity.
