This engineering samples dates back to the 45th week of 2004. That is about 9 months after the release of the single-core 90nm Prescott and about 6 months before the dual-core 90nm Smithfield was officially released. Despite being an early sample this dual-core chip had no issues at all in my ASUS P... > Read more

The Pentium D 820 was officially released on May 26, 2005. This engineering sample dates back to Dec 20, 2004 which makes it an early sample. 2004 was about single-core Pentium 4's (still) at 3GHz+ and Athlon's in the 3500+ ballpark.

I tested this sample for a short amount of time and haven't ran... > Read more

The first dual-core x86 desktop processor Intel released is the Pentium Extreme Edition 840. This CPU is technically identical to the Pentium D except that the Pentium Extreme Edition has hyper-threading technology enabled.

The normal Pentium D's were launched at May 26th of 2005. Just a little b... > Read more

An 65nm dual-core 'Netburst' engineering sample with CPUID 0F62h and speedstep bug. In other words: B1 stepping of the Pentium D 920.

This Intel Confidential QKDH got me on the LGA775 track for a while. I obtained this sample at the time when the Intel Pentium D 930 and AMD Athlon64 X2 3800+ were... > Read more

The dual-core budget CPU of 2005. Intel sold this CPU for about 130 EUR while the AMD Athlon X2 3800+ (cheapest dual-core from AMD) sold for about 300 EUR. The X2 3800+ is faster but also twice as expensive. For budget systems (especially commercially) it was ideal to sell a dual-core PC ... imagine... > Read more

Second fastest Pentium D running at 3.4GHz. Introduced early 2006 as high-end CPU just before the Core 2 Duo made it's debut in the summer of 2006. The fastest Pentium D is the 960 at 3.6GHz. The 955 and 965 use the same core but go under the flag 'Pentium Extreme Edition'.... > Read more

Intel released a cheaper version of the Pentium D; the 9x5-series. These CPU's are identical to the normal versions except that these don't have virtualization technology activated.

The D915 is like the D920 but without VT, the D925 is like the D930 without VT, and so on.... > Read more

In most cases the Pentium D 945 is equal to the Pentium D 950. They share the same core, run at the same clock-frequency and have the same cache configuration. The only exception is that the 950 has virtualization technology enabled which is an unnecessary feature for most desktop users.

The slowest Pentium D 820 when Intel first released the CPU. Later Intel released the Pentium D 805 at 2.66GHz with a lower FSB for budget dual-core systems.

Technically the Pentium D consists of two Pentium 4's merged into one 'die'. Intel had to come up quickly with a dual-core CPU since AMD wa... > Read more

Identical to this Pentium D 925. Somewhere on the lines I ended up with two of these CPU's.

The 65nm 'Presler' CPU succeeded the 90nm 'Smithfield' CPU. It ran cooler and could be clocked higher a bit. In reality it is a dual Pentium 4 and in the time-fram... > Read more
