Intel R Pentium R D CPU 2.80GHz

The Pentium D is essentially a pair of CPUs in a single package. However, it faces the same bus contention problems as two Xeons prior to the introduction of Dual Independent Bus architecture. When under heavy load, the processor can only use half its 800 MT/s FSB bandwidth.

The Pentium D is not to be confused with the Pentium Dual-Core. The last of the Pentium D processors was the Presler, which was released on August 8, 2008. Presler introduced the concept of a multi-chip module, consisting of two single-core dies placed side-by-side on the same substrate package. Presler was also supported by the same chipsets as the Smithfield and Yonah processors. It also communicated with the system using an 800 MT/s Front Side Bus.

The Intel R Pentium R D CPU 2.80GHz is slightly slower than the other CPUs in its benchmark group. However, it is capable of performing consistently under different real-world conditions. Its processors are also able to save power while they are idle. These idle states are called C0, C1 and C2. The higher the C-state, the more power-saving actions are performed.
