65w vs 125w
Is there a difference between the same CPU running at 65w vs 125w?
I see the same CPU on NewEgg with two different power requirements and I'm not sure what the difference is. Thanks! |

The difference is that one uses less electricity. This is because it runs at a lower default voltage. Normally, the lower watt one will overclock more also. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org My Tivo Experience http://wesnewell.no-ip.com/tivo.htm Tivo HD/S3 compared http://wesnewell.no-ip.com/mythtivo.htm AMD cpu help http://wesnewell.no-ip.com/cpu.php |

So I should always pick the lower watt one if possible? yes, all other features being the same. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org My Tivo Experience http://wesnewell.no-ip.com/tivo.htm Tivo HD/S3 compared http://wesnewell.no-ip.com/mythtivo.htm AMD cpu help http://wesnewell.no-ip.com/cpu.php |

It depends on your performance requirements. If the 65 watt part could perform at the level of the 125w part, they're wouldn't be a 125w part. scott |

That's just not the case with the same model CPU. All CPU's are refined over time. Some even with the core will work at the rated speed at lower voltage, thus drawing less current. The speed would be identical. The only way one would out perform the other would be by overclocking it. And a lower watt rated cpu will normally overclock higher than a higher watt rated cpu. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org My Tivo Experience http://wesnewell.no-ip.com/tivo.htm Tivo HD/S3 compared http://wesnewell.no-ip.com/mythtivo.htm AMD cpu help http://wesnewell.no-ip.com/cpu.php |

U got my vote man!... That aside... I thought a 65w jump from 125w was a lot.. If this is a Mobile-vs-Desk part then I think it's a huge dip. On a side note ( I figgure you will know ) do the mfgr's sometimes carry the same part numbers through to newgen products when there's a change to a higher density tech? |

True part numbers will always be different for one core to the next afaik. However, many times the selling model number will be the same from one gen to the next. A great example of this was with the AMD XP line of CPU's. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org My Tivo Experience http://wesnewell.no-ip.com/tivo.htm Tivo HD/S3 compared http://wesnewell.no-ip.com/mythtivo.htm AMD cpu help http://wesnewell.no-ip.com/cpu.php |

HRH Frequency has very little meaning in power consumption. My dual core 4200+ draws less power with 2 cores running at 2.2Ghz than my older single core 3000+ running at 2.0Ghz. The only time you'll see a noticeable increase in power consumption is when you increase the core voltage. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org My Tivo Experience http://wesnewell.no-ip.com/tivo.htm Tivo HD/S3 compared http://wesnewell.no-ip.com/mythtivo.htm AMD cpu help http://wesnewell.no-ip.com/cpu.php |
