Newer cpu use less power?

I have an old computer and I am wondering if I an upgraded cpu will be better performance and power wise? I have an Intel Pentium 4 560 Prescott 3.6ghz ht cpu.

I can surprisingly watch most hd movies with out too many hiccups but this is my mine primary focus. Of course I wouldn’t want to down grade in any regard.

More about newer power
  1. yes most new processors withe the same capability will use the same or lower power but will most definately perform better
  2. Yes behour as Intel and AMD shrink their process technology and improve power saving techniques and efficiency (IPC) the latest cpu's perform better.

    What mobo do you have for that system ... you may be able to swap the cpu for a dual core core2 cpu ... and leave the rest of the system as it is ... at least for an easy upgrade in the short term.

    The core2 cpus cam out first in a 65nm Conroe (dual core) and Kentsfield (quad core) package and are a lot more efficient than the Pentium 4 (Netburst) processor that you have.

    Let us know what you have ... you might be able to get a bit more life out of the system you have ... and a bit of a performance boost too.
  3. Well sadly this is an old dell xps 3 computer. So I will probably have to buy a new computer?

  4. We have a few Dell experts here ... alas I am not one of them.

    As a general rule the 915/925 chipset doesn't support core2 CPU's ... well at least the older 65nm ones ... so I can't say for sure whether you can do a simple cpu swap for some extra horespower ... like for instance an E6700 dual core.

    If you can't do a cpu upgrade then I would seriously look at a new case, cu, ram, etc ... a proper upgrade - the new core i5 and i3's are starting to drop in price ... they might be worth considering, otherwise a Phenom II (quad or triple core).

    Alternatively look at an i7 system if you want a top flight system upgrade.

    You won't be able to use the old Dell case ... possibly the HDD and Graphics card though ... but I would recomment you look at new ones anyway.

    Possibly retire the old PC to the wife ... and get yourself a complete new one !!

    I am keen to see if someone else can help out here ?
  5. I was hopping I would not have to dish out $500 bucks when I just needed a little more power.

    Well this is my mistake for buying instead of making I suppose.
    It will find a new owner so I guess I can save some cash instead of buying two new computers.

    I'll probably make a new topic asking on some help with this. I often seem to over spend.
  6. Well good luck with everything and keep us posted when your ready to buy a new one ... in the meantime run cleandisk / defrag and backup all of your important stuff so your ready to jump across and into a more sporty PC when the time comes.

    PC's are a lot cheaper now ... you can get a big boost in performance.

    Take a look at the recommended builds on the front page of THG ... there are three price categories and the article is a pretty good one to look at for advice.

    Cheers !
