Closer Look at Core Duo T2600

In this article we are going to compare dual-core processors with different architectures: Athlon 64 X2, Core Duo and Pentium D. Therefore we decided to take the top models from all three processor families for our test session. The fastest CPU in the Intel Core Duo family at the time of testing was Core Duo T2600 with the nominal clock speed of 2.16GHz. It will be our today’s second main character after ASUS N4L-VM DH in our today’s review.

Core Duo T2600 processor is based on Yonah core, features 2MB L2 cache shared between the two cores and was manufactured with 65nm process. The CPU works with 667MHz bus and its nominal core voltage lies between 1.25V and 1.4V when it runs at nominal frequency. The maximum typical heat dissipation of the Core Duo T2600 processor is 31W, just like any other CPUs from the same family. You can read more about the architectural peculiarities of the Core Duo processor in our article called Centrino Duo Mobile Platform Review. Today we will just give you a brief list of its major characteristics:

Core Duo T2600




478 pin PPGA


1.25V - 1.4V

Bus frequency


Typical heat dissipation


Core stepping


Maximum case temperature

100o C

L2 cache size


Production process


Hyper- Threading ( HT)


Intel Enhanced Memory 64 Technology (EM64T)


Enhanced Intel SpeedStep (EIST)


Intel Virtualization Technology (VT)


The Centrino Duo processor looks somewhat unusual. The thing is that mobile processors come without the top heat-spreader lid protecting the die against mechanical damage. However, end users do not usually deal with the installation of mobile CPUs, so they do not really need the protective heat-spreader.

The diagnostic CPU-Z utility reports the following info about the Core Duo T2600 processor:

Here I would only like to add that in power saving mode the clock speed of the Intel Core Duo T2600 processor drops down to 1GHz and the Vcore – down to 0.95V.
