Intel Unveils New Line of Dual-Core Processors

Core 2 Duo chips promise better performance, more efficient energy use

Intel last week launched the second generation of its dual-core processors, called Core 2 Duo. Ten new chips -- five for desktop systems and five for mobile devices -- promise improved performance and more efficient energy use. The processors are based on Intel's Core microarchitecture, which is also used in the latest Xeon server processors. It replaces the NetBurst architecture found in the Pentium 4 chip.p>

Every new processors claims to be faster, but there's a twist this time -- the Core 2 duo actually reduces its clock speed while improving in overall performance. A higher performance out-of-order engine allows the chip to get more done per clock cycle, Intel reports. The current top-of-the-line Pentium 4 processor has a clock speed of 3.8GHz. Intel's new Core 2 Duos debut with clock speeds of 1.8-, 2.1-, 2.4- and 2.7GHz.
