Sounds like 2 AMD Opteron 6200 Interlagos chips as found on many clusters. Each has 16 cores, but they have only 8 floating point units and a smaller clock then their Intel counterparts. For some codes each core gives 60% of an Intel core for many others it is 40%. The Bulldozers and the Interlogos go down in my mind as the chip that destroyed the AMD. It late, was hard to use, and underperformed.
