CPUs with highest Power/Performance Range!

This is about the difference between MAX power used and MIN power used...
Looking for DESKTOP CPUs, models with highest range...
Low power is needed wen idle, but when needed it should have the power or else the low end dual core one would be a good choice... :wahoo:
(Low power to save energy... for a low electricity bill, low heat, low fan noise and.... eco saving go Green) ;)

According to intel CPU numbering,
http://intel.com/content/www/us/en/processors/processor-numbers.html
Ones with suffix Y would use extremely low power for mobile and T is power saver option for desktop.
But do they have the range?

And also the base clock speed and max turbo frequency give a rough idea..
But is it enough!?

Thanks!.. :)

Well, the reason that AMD CPU's generate more heat is simply because of older architecture. AMD Bulldozer is made using 32nm process, Intel is using 22nm. The smaller the better. :-D I mean smaller architecture = better efficiency, i.e. more power AND less heat. Simple as that. :) I just built a new PC two weeks ago and guys here told me, that AMD's platform is overkill right now. Sure, AMD CPU's are better when using all cores, but now there is very few games and applications, that can use all 8 effectively. So if you don't do some video editing and very hardcore computing, then Intel is probably way to go... :)

Do as Traciatim said... Intel processors are much more power efficient. When idling, they underclock and undervolt. I have i5-4570 and when idling, CPU consumes only around 9W and runs at only 800 MHz frequency. And I have C6/7 states turned of in BIOS because my PSU doesn't support them.

AMD processors are made with older lithography process, generate more heat, have higher energy consumption etc.... I'd say go with at least i5, if you want more power, however even basic i3 is powerfull enough for most common tasks. ;)

Hi! From personal preference if your looking for a i5 cpu (this is my personal gaming rig cpu) i would go with the i5 3570k, Because it's "cheap" and preforms very well, It is as well a great overlocker! With a good cooler you could get this cpu pretty beasty, or beastier than it already is, and if your going for a i7 than the 3770k, if you really want a very little benefit. an overlocked 3570k could easily whoop a 3770k by far! But again it's all personal preference, Hope this helped Max.

Thanks Everybody!.. :)

@coathanger
Im not sure that AMD cpus generate more heat!..
They seems to use more power, it is in specs and could be true, and probably won't slow down as Intel.
But we checked 2 AMD CPUs, when doing normal stuff like browsing.. CPU temp was about 37 C.... !!!
(No special cooling, no A/C)
The body temp.... And all Intel ones come to at least 40 C...
First time we were not sure, we opened ther case and touched Heat Sinks to check... It was cool!...
I know years ago, whhen there were Athlon, XP etc... AMDs were like ovens... It was more than 10 years ago...
Just shared we experienced.... :)
Since this is about not heat, but power consumption, Intel is the option...

@ Tredway423
Im not looking for a gaming....
Just the power consumption difference.... But since gaming does not need much powerful CPU compare to GPU,
I think your suggestions are not bad... But K series cpus are not what I need
:)

Again, Thanks Everybody!.. :)

They do make the i5 3570 and 3570k, So if your not looking for a "k" series they do make just the 3570.
