In fact, this dual-core chip, code-named "Smithfield," is actually a pair of Pentium 4 "Prescott" cores situated together on a single piece of silicon. Each core has 1MB of L2 cache onboard, and the two cores share an 800MHz front-side bus. Beyond the Siamese twins action, there's very little to differentiate these chips from the latest Pentium 4 processors like the 600 series. Like those chips, Smithfield features support for Intel's EM64T extensions for 64-bit computing, and it can save on power consumption via the one-two punch of an enhanced halt state and SpeedStep power management.
