Intel Core 2 Duo T7800 vs Intel Core 2 Duo T7500 vs Intel Core 2 Duo T5550
Intel Core 2 Duo T7800► remove from comparison
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.
Intel Core 2 Duo T7500► remove from comparison
The Core 2 Duo T7500 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 T7500 was a very fast CPU and had enough performance for games and applications in 2008. In 2009, the Core 2 Duo T7500 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.
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.
