I have 2 old laptops - an IBM ThinkPad Z61t and a Dell Latitude E6500. The ThinkPad has an Intel Centrino Duo and the Latitude has an Intel Centrino 2. The Latitude has significantly better performance not due to RAM, so I'm wondering if the processors are different, but I thought they were the same. The question is: are they different, and are they compatible?

These are two different generations of of Intel's Centrino line of processsors. The Centrino Duo was the earlier iteration and the Centrino 2 is the successor to the Centrino Duo.
The Centrino Duo processors came with a 800MHz front-side bus and CPU clock speeds up to 2.4GHz. The Centrino 2 processors had an improved 1,066MHz front-side bus and were available with CPU clock speeds up to 3.06GHz.
Centrino Duo and Centrino 2 processors are not compatible in that the are supported by different sockets. The sockets supported by Centrino Duo are PBGA479 and PPGA478. The sockets supported by Centrino 2 are BGA479 and PGA478.
