Difference between Pentium D and Pentium Dual-Core?

What is the difference between Pentium D and Pentium Dual-Core? Which one is better and latest when both are compared?

Pentium D is older.

Pentium Dual Core is newer, based on newer Core 2 Duo.

When Compared Pentium D are slower and inefficient because they are based on Pentium 4 processors while Dual Cores are better, efficient, faster, overclockable, require less power to run.

One processor = Pentium D = Slower

Two Processors(cores)= Dual Core & Core 2 Duo = Twice Faster Than pentium D

Pentium dual core is better because the CPU architecture is better. Pentium dual core uses the same architecture as the core2duo series but has a lower FSB (connection between processor and the rest of the system especially RAM).

The main advantage of this new architecture is that it processes more instructions per clock cycle compared to the pentium d. For example: a Pentium dual core e5200 running at 2.5Ghz is 50% faster than a pentium d 3 ghz cpu.

Pentium D has two cores too. Its just that the architecture is slower.

Yeah My bAD!!

Pentium D is just two cores glued together, while Dual Core and Core 2 duo have the cores work in sync together with better communication among themselves and with the rest of the system

IIRC, Pentium D < Dual Core < Core 2 Duo.

nice summary
