Intel Core 2 Duo T6400 vs Intel Core 2 Duo P7450 vs Intel Core 2 Duo T6600

Intel Core 2 Duo T6400

► 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 P7450

► remove

The Intel Core 2 Duo P7450 is a dual core processor for laptops. It features 2.1 GHz and a shared level 2 cache of 3 MB. It is based on the 45nm Penryn core, but Trusted Execution and Virtualization (VT-x) are disabled.

The P7450 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).

Intel Core 2 Duo T6600

► remove

The Intel Core 2 Duo T6600 is an entry to mid-range dual core processor for laptops. It is based on the Penryn architecture, but features only 2 MB level 2 cache and a mediocre clock rate of 2.2 GHz. Compared to the similar T6670, the T6600 does not feature Virtualization features in hardware and is speced at a lower maximum temperature.

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 T6600.
