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 T5800

► remove from comparison

The Intel Core 2 Duo T5800 is an entry level dual core processor based on the old Merom core. It features a reduced level 2 cache to 2 MB and no virtualization functions. Furthermore, the clock rate of 2 GHz is relatively slow.
