Try comparing them with stream-scaling to see what happens:

You can't really test CPU performance in a simple way anymore; it varies
depending on the number of processes running at once. This test is the
best way I've found to show how that works. On a single thread, the
X3450 may not be significantly better than the E5535. But what should
happen is that total speed keeps going up as you add more threads on the
newer system, while the old DDR2 model stays as the same basic total.
