Intel Core 2 Duo P9700 vs Intel Core 2 Duo SL9600 vs Intel Core 2 Duo SP9400
Intel Core 2 Duo P9700► remove from comparison
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 SL9600► remove from comparison
The Intel Core 2 Duo SL9600 is a low power laptop processor for small and slim laptops. It features the full 6 MB level 2 cache and all features of the Penryn core (e.g. VT-x and Trusted Execution). Due to the large cache, the CPU shows a good performance for the small clock rate. However, in the MacBook Air, the CPU throttled very often, leading to the slower benchmarks in our database.
Compared to other Core 2 Duo models, the C2D SL9600 only supports the socket BGA956 and is soldered in the MacBook Air models.
Intel Core 2 Duo SP9400► remove from comparison
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.
