"The projected Cayman has 17% higher memory bandwidth, roughly 2.5X the raw single precision FLOP/s and 26% higher raw double precision FLOP/s than the Tesla C2070. However, AMD's VLIW microarchitecture is inherently less efficient, and the memory hierarchy is also incredibly sensitive to the workload. For single precision applications that are primarily regular computation and regular memory access patterns, Cayman should have good utilization within each VLIW4 offer incredibly attractive performance. Even in the case of a bandwidth bound application, Cayman will be on-par or slightly ahead of the Tesla. For double precision though, Fermi is likely to be the higher performance option. The two GPUs have similar raw performance, but the inefficiencies of the VLIW will drag down AMD's actual performance."

But when AMD is running double-precision code, there is no VLIW-inefficiency as all the units are together executing same DP operation, and there is no need to find parallel operations to execute, it's acting like a scalar processor.
