As expected, Intel has started shipping the Pentium 4 662 (3.6 GHz) and 672 (3.8 GHz), featuring its Virtualization Technology (VT), which creates virtual machines capable of running different operating systems on the same processor. The single-core chips specs are identical to those of the current 660 and 670: 2 MB of L2 cache, 800 MHz FSB, HyperThreading, EM64T and Execute Disable. The 662 costs USD 401, while the 672 sells for USD 605, both in 1,000-unit quantities.
