Intel Core 2 Duo SU9300 vs Intel Core 2 Duo T6400 vs Intel Core 2 Duo P9600
Intel Core 2 Duo SU9300► remove from comparison
The Intel Core 2 Duo SU9300 is a power efficient ULV 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.
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 P9600► remove from comparison
The Intel Core 2 Duo P9600 was a upper middle class dual core CPU for laptops, at the time of introduction. It is similar to the Core 2 Duo T9550 except for the lower TDP of 25 versus 35 Watt).
Due to the relatively high clock speed and 6MB Level 2 cache, the P9600 offers enough performance for demanding games (in 2009) and applications. The newer Core i3-330M should deliver a similar performance due to the hyperthreading support.
The P9600 uses a Penryn (Montevina Update) core that features 2 integer units, 1 floating point unit, 1 load unit, and 1 store unit in a 14-stages long pipeline. Due to the Wide Dynamic Execution Technology, the core is able to simultaneously execute up to four instructions.
The integrated Enhanced Speedstep is able to downclock the core dynamically to save power (in idle mode).
