Message boards : Macintosh : AVX application for Mac

After having recently compared runtimes amongst my finished WUs I realised that across different OS the avx applications usually show a huge advantage over sse2 applications. Comparing those runtimes to the average runtime of my WUs (sse2 application), that performance difference amounts to a whopping ~4-5 times. | |

I haven't seen anything nearly as much as 4-5 times faster with the AVX app over the FMA or SSE2 apps. Valterc himself has said the AVX and FMA apps only provide a small increase in speed, probably under 10%. | |

Thanks for getting back to me and sorry for my assumptions that lead to this fallacy. I have to admit that I didn't conduct my analysis thoroughly but you are completely right. Most of the systems, I compared my runtimes to, were Linux based and a small subset thereof were newer model Ryzen chips which obviously were the ones with the best runtimes. What they all had in common was however that all were running the avx application. That's were my naive conclusion was coming from. | |

Linux is indeed faster when compared to Windows. However I'm not sure about Mac OS. | |

Main difference is the more modern cpu architecture of the Ryzen 3000 cpus using Zen 2 microarchitecture. | |

Thank you guys for responding. Meanwhile I ran a few tasks on my X5660 Xeon based Dual boot machine with Win10 and Linux Mint and Linux indeed on average yields slightly improved but way more stable runtimes around ø 27,000 sec vs. 26,000-29,000 sec on the Win10 partition. However my "newer" laptop i5 Haswell CPU reduces the runtime by ~40-50%, so nearly cuts it in half. | |
