Has anyone done some recent smpar-only WRF benchmarking of these two

Intel Xeon X5660 (6 core, 2.8 GHz)
AMD Opteron 6174 (12 core, 2.2. GHz)

You can get twice as many cores from the AMD system compared to the
Intel system, for about the same amount of money.  

Note I'm not interested in dmpar scaling, so only up to 24 (Intel) or 48
(AMD) cores per run.  I typically have many 5-day chunks to run, so I
use smpar only.
