Intel Core 2 Duo T8300 vs Intel Core 2 Duo SL9400 vs Intel Core 2 Duo P7370
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 SL9400
► remove from comparison
The Core 2 Duo SL9400 is a power saving low voltage CPU for thin and light laptops. It offers a good performance for the 1.86 GHz clock rate, as it features the full 6 MB level 2 cache of the used Penryn core.
Intel Core 2 Duo P7370
► remove from comparisonThe Intel Core 2 Duo P7370 is a dual core processor for laptops. It features 2.0 GHz and a shared level 2 cache of 3 MB. It is based on the 45nm Penryn core, but most likely Trusted Execution and Virtualization (VT-x) are disabled.
The P7370 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 as low as 800 MHz to save power (in idle mode).
