Intel® Pentium® D Processor

The Pentium D brand refers to two series of dual-core 64-bit x86 processors with the NetBurst microarchitecture manufactured by Intel. Each CPU comprised two dies, each containing a single core residing next to each other on a multi-chip module package. The brand's first processor, codenamed Smithfield, was released by Intel on May 25, 2005. Nine months later, Intel introduced its successor, codenamed Presler, but without offering significant upgrades in design, still resulting in a relatively high power consumption. By 2005, the NetBurst processors reached a clock speed barrier at 4 GHz due to a thermal (and power) limit exemplified by the Presler's 130 W Thermal Design Power (a higher TDP requires additional cooling that can be prohibitively noisy or expensive). The future belonged to more efficient and slower clocked dual-core CPUs on a single die instead of two. The final shipment date of the dual die Presler chips was August 8, 2008, which marked the end of the Pentium D brand and also the NetBurst microarchitecture.
