Is it true that a 1.6ghz centrino processor is equivalent to 3.2ghz of pentium 4?

like i have a 1.6ghz centrino duo.. and i tried playing battlefield 2142 but it wont work because i have a 1.6ghz processor but then i have a centrino duo as my processor and for the system requirements for battlefield 2142 is 1.7ghz for pentium 4.. like i heard that centrino is x2 clockwork or timeframe or whatever of pentium 4.. so my processor speed is actually 3.2ghz if it was to be converted to pentium 4 speed.. so i was wondering if it is true or not.. and if it is.. what could help me solve this problem?
