Intel Core 2 Duo P9500 vs Intel Core 2 Duo T8300 vs Intel Core 2 Duo SU7300
Intel Core 2 Duo P9500
► remove from comparison
The Intel Core 2 Duo P9500 was a upper middle class dual core CPU for laptops, at the time of introduction. It is similar to the Core 2 Duo T9400 except for the lower TDP of 25 versus 35 Watt).
Due to the relatively high clock speed and 6MB Level 2 cache, the P9500 offers enough performance for most demanding games (in 2009) and applications.
The P9500 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 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 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.
