Intel is back in the spotlight with an evolution of the Prescott core. Three main innovations have been introduced compared to the Pentium 4 5xxJ, which was released last November. The cache L2 has been increased from 1 MB to 2 MB and it supports Enhanced Intel SpeedStep (EIST) and Enhanced Memory 64 (EM64T) technologies. Behardware.com has tested the Pentium 4 660 and EE 3.73 GHz processors to see if this new series will be good enough to compete with AMD?s products.
