Intel Core 2 Duo T9400 vs Intel Core 2 Duo T6400 vs Intel Core 2 Duo T6500

Intel Core 2 Duo T9400

► remove Intel T9400

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).

► remove

The Intel Core 2 Duo T6400 is an entry level dual core processor for cheap laptops. It is based on the Penryn core but offers only 2 MB level 2 cache and a slow clock speed of 2 GHz. The performance should be sufficient for office and other casual tasks but high level gaming and HD video editing for example could be limited by the CPU performance.

Intel Core 2 Duo T6500

► remove

The Intel Core 2 Duo T6500 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 T6570, the T6500 does not offer Virtualization VT-x and is therefore aimed at consumer 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 T6500.
