Intel Core 2 Duo SU7300 vs Intel Core 2 Duo SU9300 vs Intel Core 2 Duo SP9300
Intel Core 2 Duo SU7300
► remove from comparisonThe Intel Core 2 Duo SU7300 is a CULV laptop processor for small and light laptops. Due to the small clock speed, the CPU is specified with a TDP of only 10 Watt. For non demanding tasks, the performance of both cores is sufficient. Many laptops with the SU7300 feature an overclocking option to run the CPU at higher clock rates (e.g. 1.7 GHz in the Asus UL series). Compared to the Atom series, the SU7300 is signifantly faster.
Intel Core 2 Duo SU9300
► remove from comparisonThe 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 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.
