. The Core 2 Duo is a part of this series and refers to the dual core processors that were produced from 2006 to 2008 for desktop PCs and mobile devices. With us you will therefore find both used notebooks with Intel Core 2 Duo processor as well as individual CPUs to upgrade an existing system. The operation is possible depending on the model 775, P, or M. There are built on similar technology and server models, these facilities are available in the category of our used Xeon processors.

What are the differences between the various models?

desktop processors

E models

This LGA775 Socket CPU's are also located in many of our refurbished computer. You will receive not only sufficient computing power for the office, but a total energy-efficient system. The thermal design power is 65 W, during operation can also be lower. The two existing cores deliver up to 3.33 GHz and have a maximum of 6 MB of L2 cache (Intel Core 2 Duo E8600). In this and other models is already VT-x (Intel Virtualization Technology) included, so that also represent virtualisations no problem. Take advantage of one of our used computer and see for yourself of the possibilities.

P models

Here, the P stands for "power optimized", which CPUs are meant to be used efficiently in spite of higher performance. The power dissipation of 25 W thereby drives two cores which have a maximum of 2.66 GHz clock rate. The cache of more than 6 MB ensures you again for an increase in computing power. These models
are therefore perfectly adequate for economical notebooks and normal office work.

With these models, you get a very economical CPU that W (L models) or 10 W (U models) used in the operation 17. However, both in terms of cache, as well as reduce the switching frequency, so 1.8GHz is the maximum here. For you, the insert can but especially worth it if you place a lot of importance to the life of your notebook, but otherwise run applications that have high performance requirements.

T models

The top model of the Intel Core 2 Duo T9900 achieved here with two cores, a clock frequency of 3.06 GHz and yet consumes only 35 W. In general, the limit of 39 W is not exceeded by the T-models, whereby power consumption is slightly higher, although , but also the performance increases significantly. They are therefore designed for notebooks with 64-bit operating system, go with those and again, more complex tasks must be performed.


The prefix S stands for "Small Package". The CPUs are indeed powerful technically very similar to those described above, however, it is not interchangeable because they are not operated in a standard socket, but soldered directly to the motherboard.
