First, running gromacs on laptop is a fast way to kill it. To keep a 
laptop CPU running at 100% all time is a challenge even to a  
energy-sensitive smart centrino or turion. They simply have no way to 
escape. =)
Second, because Gromacs' advantage is its assembly loops using SSE/SSE2, 
which is not part of x86 instruction. Besides, AMD's 64bit is fully 
compatible 32bit software.

Dual core shall be better but you need benchmark for it.
