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 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.
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.
