Intel Core 2 Duo T6400 vs Intel Core 2 Duo T5500

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 T5500

► remove from comparison

The Intel Core 2 Duo T5550 is an entry-level dual core processor for laptops. It is based on the Merom-2M core and therefore manufactured in 65nm. It does not support Virtualization functions VT-x of the Merom core and offers only a low clock speed and 2MB level 2 cache.
