“The improvements in the Xcode 6.3 Beta have provided a 1.4x speedup for GEMM and a 2.6x speedup for FFT over Xcode 6.1.1,” Schmieder reports. “Performance for the C++ workloads did not change, so we omit those numbers for the 6.3 Beta.”
“After the improvements in Xcode 6.3 and some careful optimizations, the performance of the FFT workload is now within 10% of the C++ implementation,” Schmieder reports. “The optimizations might look strange to someone who hasn’t read up on Swift internals, but they are easy to apply and can be used by any Swift programmer.”
