Intel Core 2 Duo T8300 vs Intel Core 2 Duo T6570 vs Intel Core 2 Duo SU7300
Intel Core 2 Duo T8300
► remove from comparisonThe Intel Core 2 Duo T8300 was at the time of announcement a fast dual-core CPU for laptops with 3 MB level 2 cache. It is based on the Penryn core with all features enabled (but without the full 6MB level 2 cache). The later announced Core 2 Duo P7450 was cheaper and used less power.
Intel Core 2 Duo T6570
► remove from comparisonThe Intel Core 2 Duo T6570 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 T6500, the T6570 offers Virtualization VT-x and is therefore aimed at business 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 T6570.
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.
