Sandybridge and Ivybridge do not have AVX2 extensions. Haswell does. Therefore SB and IB do 8DP FLOPs/clk/core HW does 16DP FLOPs/clk/core
AMD processors Interlagos,Abudhabi support FMA4 and FMA3/4 respectively. They are capable as well of 8DP FLOPs/clk/core. floating point operations in single precission is 2X double precission for multicore architectures. You should not guide your infrastructure investments on SP/DP FLOPs/clk/core metric. Better access temporarily it and run your own stuff. Memory bandwidth and latency at the core and socket will correlate better on real world workloads ( the part not related with I/O to NIC or storage).
