http://www.maxxpi.net/pages/result-brow ... -flops.php It's cool how much better the latest processor is than a Pentium 4. 781.93 MFlops Intel Pentium 4 (3055MHz) 20,437.44 MFlops Intel Core i7 X 980 (4515MHz) |

Interesting. Apparently they're using HT when counting cores, because that i7 really only has 6 physical cores, not 12. On that basis, you can break down the performance gains: Core efficiency: 2.95 : 1 Core clock: 1.48 : 1 Core count: 6 : 1 Also, although the total FPU performance ratio is about 26.1 : 1, if we look at performance per watt, it's more like 16.4 : 1. |

Yeah, they should not count hyperthreading when counting the number of cores. |

In a semi-related question; does anything used by home-users other than video-games even come close to utilizing any of that? |

IE8 probably does. *buh-dum-tish!* |

Well, if we're talking solely about FLOPs, audio/video encoding would. Decoding too, but that's much faster anyway. Compositing window managers (pretty much every contemporary OS GUI) would theoretically benefit. And certainly if you participate in any of the big scientific distributed computing projects (ex. folding@home), that will benefit a lot from better FLOPS throughput. If we're taking a broader view, including increased parallelism, then lots of other things can/do benefit. Obviously any sort of multi-tasking benefits. But beyond that, a lot of common, time-consuming tasks like searching, sorting, and compression algorithms can benefit almost arbitrarily from parallelism if they're written accordingly. |

Yeah, I've really noticed with my i7 920 that it really doesn't matter how many applications I have open. Performance doesn't degrade. I'll regularly run WoW/LOTRO/PotBS along with Outlook, iTunes and multiple tabs of IE all running the same time and performance in game is indestinquishable between that and when only the game is running. That would have not been the case with older computers. |

Wait, you're playing PotBS? |

Kinda. When it went FTP, I recreated my old account and made a new toon to play with a buddy. He's all of lvl 8 atm I think. British privateer on the US server. |
