Can you please give specs on both CPUs? (The exact manufacturer and model.)

Is there a reason why you think one CPU is better than another? You can
have a CPU that's old and fast at single threaded jobs (say an old
overclocked dual core 4.0Ghz CPU) and a newer CPU that's slower at single
threaded jobs and faster at multi-threaded jobs (say a Core i7 3.2GHz). Is
the program you're trying to run written in such a way as to take advantage
of multi-threading? Was the benchmark you mentioned a single threaded or
multi-threaded benchmark?

Best wishes,
James Alton
