The Pentium D 950 has a 200- MHz FSB that is quad-pumped (FSB800). We used our Pentium Extreme Edition 955 test sample, disabled Hyperthreading and changed the clock speed in order to benchmark all Pentium D speed grades.

The first product of the 65 nm generation was the dual core Pentium Extreme Edition 955, which we reviewed in late December. It is based on the Presler dual core, which now also powers the regular Pentium D 900 family. Presler is nothing else than a combination of two Cedar Mill Pentium 4 single cores into one package, which adds up to an impressive 4 MB L2 cache.

We could not take a look at the single-core Pentium 4 6x1 family yet because Intel did not provide test samples. This makes sense for the chip giant because it clearly focuses on dual-core processors now. In addition, we can understand that Intel also does not want the media to focus on the single-core parts, because these do not perform any faster than the 90 nm Prescott-2M cores. Lastly, the 3.6 GHz Pentium 4 based on a 65 nm process has yet to reach the high clock speeds of 3.8 GHz 90 nm devices.

The Pentium D does not support Hyperthreading, so the task manager shows two threads only.

The device manager shows two units as well.
