Intel Core 2 Duo SP9300 vs Intel Core 2 Duo P9600 vs Intel Core 2 Duo T6500
Intel Core 2 Duo SP9300
► remove from comparisonThe Core 2 Duo SP9300 is a power efficient (25W TDP) dual core CPU for laptops. Compared to other Core 2 Duo with 2.26 GHz, the SP9300 features the full 6 MB level 2 cache of the Penryn core. Usually 3MB are enabled for 25 W CPUs at this clock range (e.g. P8400). Therefore, the performance is a bit better than similar clocked C2D CPUs.
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).
Intel Core 2 Duo T6500
► remove from comparisonThe Intel Core 2 Duo T6500 is an entry level dual core processor for laptops. It is based on the Penryn core but offers only 2 MB level 2 cache and a slow clock rate of 2.1 GHz. Compared to the Core 2 Duo T6570, the T6500 does not offer Virtualization VT-x and is therefore aimed at consumer notebooks.
The performance should be suited for non demanding applications like office, internet, entry level video editing or image correction. CPU intense games may be limited by the power of the T6500.
