Intel Core 2 Duo T6400 vs Intel Core 2 Duo SL9400 vs Intel Core 2 Duo T6770

Intel Core 2 Duo T6400

► remove from comparison

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 SL9400

► remove from comparison 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.

Intel Core 2 Duo T6770

► remove from comparison

The Intel Core 2 Duo T6670 is a laptop processor based on the Penryn core. It offers only 2 MB level 2 cache and is therefore slower than other 2.3 GHz clocked Core 2 Duo CPUs.
