Intel Core 2 Duo SL9380 vs Intel Core 2 Duo P9700 vs Intel Core 2 Duo SU9600
Intel Core 2 Duo SL9380► remove from comparison
The Core 2 Duo SL9380 is a power saving low voltage CPU for thin and light laptops. It offers a good performance for the 1.8 GHz clock rate, as it features the full 6 MB level 2 cache of the used Penryn core. Compared to the SL9400, the SL9380 offers only an FSB with 800 MHz clock rate (instead of 1066) and exactly 1.8 GHz (SL9400 1.86).

The Intel Core 2 Duo P9700 is a high end dual core CPU for laptops (at the time of introduction). It is the fastest Core 2 Duo P-model and the performance is comparable to the Core 2 Duo T9600. Still the TDP rating is considerably better (28 versus 35 Watt).
Due to the high clock speed, the P9700 offers enough performance for demanding games (in 2009) and applications.
The P9700 uses a Penryn 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 (in idle mode).
The Core 2 Duo P9700 can be used in a Socket P socket with 479 pins.
Intel Core 2 Duo SU9600► remove from comparison
The Intel Core 2 Duo SU9600 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 a bit limited, but should be sufficient for everyday tasks.
