On i7-2600K SSE2 is the same that SSE3. | |

There is a differrence in 2 or 3 basic instructions, which are replaced by couple of sse2 instructions. SSE2 version has some small improvements than older SSE3. | |

So is the SSE2 faster than SSE3 or is it for older computers? | |

So is the SSE2 faster than SSE3 usually this will not be the case because some design-flaws in SSE2 (which affect performance) were fixed with SSE3. | |

Is AVX being planned? I have quite a few cpu's which support it... :) | |

Is AVX being planned? I have quite a few cpu's which support it... :) I saw a reply by HA SOFT that said it was actually slower than the SSE3 app. There was also discussion of AVX2 support which *should* be faster again, but they have yet to build such an app. ____________ BOINC blog | |

Is AVX being planned? I have quite a few cpu's which support it... :) Meanwhile, my company has bought one Intel Haswell PC with i5-4670 for testing. AVX version is better on this cpu. All other CPUs than Haswell perform better with SSE3. You can look on beta version times here: http://asteroidsathome.net/boinc/results.php?hostid=45724&offset=0&show_names=0&state=4&appid= It's pure AVX version (no AVX2 instruction). App is finished and Kyong is testing it now. The problem is a detection on boinc server side. Kyong is discussing this with boinc development. AVX needs CPU and OS support (linux kernel 2.6.30+ and win7SP1+). | |
