Intel today rolled out its latest notebook-oriented CPU, the Mobile Intel Pentium 4 548. Pitched at desktop-replacement systems, the 548 is clocked at 3.33GHz and supports HyperThreading. Fabbed at 90nm, the "Prescott"-derived part includes 1MB of L2 cache and SSE 3 support. Enhanced SpeedStep technology is included to keep the heat dissipation down.
