Pentium D is a dual-core version of Pentium 4, and Pentium Extreme Edition is a Pentium D with Hyper-Threading technology enabled. Pentium D and Pentium Extreme Edition CPUs can be found using two different core versions: Smithfield and Presler. In this tutorial we will talk about these two core versions and we will also list all Pentium D and Pentium Extreme Edition models released to date.
Pentium D and Pentium Extreme Edition are based on Intels 7th generation microarchitecture, a.k.a. Netburst. I.e. besides their different name, Pentium D and Pentium Extreme Edition are internally a Pentium 4. The basic difference between Pentium D and Pentium Extreme Edition is the absence of the Hyper-Threading technology on Pentium D.
Do not confuse Pentium Extreme Edition with Pentium 4 Extreme Edition. The former is a dual-core processor, while the later is a single-core CPU.
For an in-depth understanding of Pentium D and Pentium Extreme Edition, we suggest you to read the following tutorials: Intel Dual Core Technology, Inside Pentium 4 Architecture and All Pentium 4 Models, this one if you wish to compare Pentium Ds technical specs to Pentium 4s.
Now lets talk about all Pentium D and Pentium Extreme Edition models released so far.
