Intel Core 2 Duo T6400 vs Intel Core 2 Duo T6770 vs Intel Core 2 Duo SU9400

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 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.

Intel Core 2 Duo SU9400

► remove from comparison

The Intel Core 2 Duo SU9400 is a power efficient subnotebook processor based on the Penryn 3M core. It features all functions of the Penryn core, like Virtualization (VT-x), Trusted Execution and Speedstep. Due to the low core clock, the performance is limited.
