Intel Core 2 Duo T9400 vs Intel Core 2 Duo T6770 vs Intel Core 2 Duo SL9380
Intel Core 2 Duo T9400► remove from comparison
The Intel Core 2 Duo T9400 was a uppder middle class dual core CPU for laptops, at the time of introduction. It is similar to the Core 2 Duo P9500 except for the higher TDP of 35 versus 25 Watt).
Due to the relatively high clock speed and 6MB Level 2 cache, the T9400 offers enough performance for most demanding games (in 2009) and applications.
The T9400 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 T6770► remove from comparison
The Intel Core 2 Duo T6670 is a laptop processor based on the Penryn core. It offers only 2 MB level 2 cache and is therefore slower than other 2.3 GHz clocked Core 2 Duo CPUs.
Intel Core 2 Duo SL9380► remove from comparison
The Core 2 Duo SL9380 is a power saving low voltage CPU for thin and light laptops. It offers a good performance for the 1.8 GHz clock rate, as it features the full 6 MB level 2 cache of the used Penryn core. Compared to the SL9400, the SL9380 offers only an FSB with 800 MHz clock rate (instead of 1066) and exactly 1.8 GHz (SL9400 1.86).
