Intel Core 2 Duo T7400 vs Intel Core 2 Duo T9550 vs Intel Core 2 Duo P7450

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 T9550

► remove from comparison Intel T9550

The Intel Core 2 Duo T9550 was the middle class dual core CPU for laptops at the time of introduction. It is similar to the Core 2 Duo P9600 except for the higher TDP of 35 versus 25 Watt.

Due to the relatively high clock speed and 6MB Level 2 cache, the T9550 offers enough performance for demanding games (in 2009) and applications. 

The T9550 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 P7450

► remove from comparison

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).
