All Pentium D and Pentium Extreme Edition Models
By Cássio Lima on September 15, 2007


Introduction

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 Intel’s 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 D’s technical specs to Pentium 4’s.

Now let’s talk about all Pentium D and Pentium Extreme Edition models released so far.

Smithfield

Pentium D and Pentium Extreme Edition processors from 800 series are based on Smithfield die, which is simply two Prescott chips assembled together, as you can see in Figure 1. It has 230 million transistors occupying an area of 206 mm2 (0.319 sq inch) and manufactured using 90-nm technology.
