Intel Core 2 Duo SL9380 vs Intel Core 2 Duo SP9400 vs Intel Core 2 Duo P9600
Intel Core 2 Duo SL9380► remove
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 SP9400 is a laptop CPU with the full 6MB level 2 cache at 2.4 GHz and a TDP of only 25 Watt.
Intel Core 2 Duo P9600► remove
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).
