Intel refreshes mobile processor line up

Intel launched mobile versions of its latest Pentium 4 chips on Tuesday, bringing technology introduced in its newest processor family, developed under the code name Prescott, to the notebook PC space.

The three new Pentium 4 processors, along with one new Celeron model, also feature Intel's recently introduced naming convention, under which each processor is denoted with a model number meant to illustrate its overall performance.

The chip giant said the three P4s, which are aimed at larger notebook PCs, will be known as 538, 532, and 518, and run at speeds of 3.2GHz, 3.06GHz and 2.8GHz, respectively. The chips also feature Hyper-Threading Technology support, a 1MB Level 2 cache and upgrades to Intel's NetBurst design architecture.

The new Celeron M processor 340, which will be targeted at thin and light notebooks, operates at 1.5GHz and offers 512KB of L2 cache, a 400MHz system bus and a low-voltage processor core design.
