Hi,
When _calculating_ peak performance on Xeon it is usually assumed
that two Flops can be performed during one clock step
e.g. http://www.top500.org/sublist/System.php?id=7293
(although in practise it is rarely the case).

The easiest way _measure_ peak performance on the Intel platform is probably to check 
http://www.intel.com/cd/software/products/asmo-na/eng/perflib/clustermkl/219821.htm
which will make you going.
