Intel Core 2 Duo T7400 vs Intel Core 2 Duo T5550 vs Intel Core 2 Duo T7800

Intel Core 2 Duo T7400

► remove from comparison

The Intel Core 2 Duo T7400 is a mobile dual core processor based on the Merom core. In 2006, the T7400 was a mid-range to high-end laptop processor. In 2010, the performance is only in the entry level segment. Later announced Penryn based Core 2 Duo processors are manufactured in 40nm and feature a higher speed per clock rate. Therefore, the Core 2 Duo P7450 is a bit faster and also more power efficient.

Intel Core 2 Duo T5550

► remove from comparison

The Intel Core 2 Duo T5550 is an entry-level dual core processor for laptops. It is based on the Merom-2M core and therefore manufactured in 65nm. It does not support Virtualization functions VT-x of the Merom core and offers only a low clock speed and 2MB level 2 cache.

Intel Core 2 Duo T7800

► remove from comparison Intel T7800

The Intel Core 2 Duo T7800 is compareable to the Core 2 Extreme X7800 but featuring a lower TDP and a fixed multiplicator. It is a middle class dual core cpu in 2009 (at the time of announcement it was one of the fastest). Later the Penryn based Core 2 Duo CPUs succeeded the T7800.
