oh, indeed the top bin Xeon systems are fast and damn expensive. Even when we purchased these AMD systems they were a LOT cheaper than any Intel system that could come close in specfp rate performance - let alone after 4 years of heavy use.
One issue is that the AMD systems are far more numa, thus requiring tighter programming. I was trying to justify tossing the AMD systems and hopefully replacing them with a smaller number of broadwell based systems. I guess I was really surprised to see that a reasonable dual socket (what we would likely purchase) broadwell system probably wasn't any faster. Of course, per socket, they are about 2x thus saving us a lot of space+power, but not the ~10x I was hoping to see. It has been 4 years...
