Intel Core 2 Duo SP7500 vs Intel Core 2 Duo T7600

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 Core 2 Duo T7600 is a middle class dual core CPU for laptops. It is based on the Merom core and features 4MB Level 2 cache.

At the time of announcement, the T7600 was a very fast CPU and had enough performance for games and applications in 2008. In 2009, the Core 2 Duo T7600 performed similar to a middle class Core 2 Duo P7570 or Turion II Ultra M640/M660.

Modern Penryn based Core  2 Duo are a bit faster per MHz (with similar Cache sizes) and are more power efficient (due to the 45nm process).
