Intel Core 2 Duo T9400 vs Intel Core 2 Duo T9550
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).
