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.
The Core 2 Duo SP7500 is a low power Core 2 Duo based on the Merom core that was used in the MacBook Air (but due to throttling could not show the full performance).
The Intel Core 2 Duo T7700 was the fastest Merom based Core 2 Duo with 35 Watt TDP (the Core 2 Extreme was faster, but featured a higher TDP). The Penryn based successor (e.g. Core 2 Duo T8300) is a bit faster at the same clock speed.
