Intel Core 2 Duo T6400 vs Intel Core 2 Duo T6600 vs Intel Core 2 Duo SL9400

Intel Core 2 Duo T6400

► remove

The Intel Core 2 Duo T6400 is an entry level dual core processor for cheap laptops. It is based on the Penryn core but offers only 2 MB level 2 cache and a slow clock speed of 2 GHz. The performance should be sufficient for office and other casual tasks but high level gaming and HD video editing for example could be limited by the CPU performance.

Intel Core 2 Duo T6600

► remove

The Intel Core 2 Duo T6600 is an entry to mid-range dual core processor for laptops. It is based on the Penryn architecture, but features only 2 MB level 2 cache and a mediocre clock rate of 2.2 GHz. Compared to the similar T6670, the T6600 does not feature Virtualization features in hardware and is speced at a lower maximum temperature.

The performance should be suited for non demanding applications like office, internet, entry level video editing or image correction. CPU intense games may be limited by the power of the T6600.

Intel Core 2 Duo SL9400

► remove Intel SL9400

The Core 2 Duo SL9400 is a power saving low voltage CPU for thin and light laptops. It offers a good performance for the 1.86 GHz clock rate, as it features the full 6 MB level 2 cache of the used Penryn core.
