energy efficiency Intel or AMD Core Duo E

[niels63]

I am looking for a standard PC for office applications.

Energy effinciency is important to me.

For example I see offerings with 2 CPU's , with for me similar specifications (please correct me if I am wrong!):
Intel's Core Duo E4500, 2.2 GHz
or
AMD's Athlon X2 Core Duo 4450e, 2.3 GHz.

Both claim high energy efficiency.
TDP of AMD is 45 W, of the Intel E4500 is 65 W.

Which is the more energy efficient for office use?

For basic office use I'd go with the AMD. Better efficiency and a better graphics card to boot if you get a 780G. I'd say a better intel equivelant would be the E2200 though. The 4450e is much cheaper than the E4500.

Even an AMD 740g IGP chipset (which is the 690 refresh with sb700) may work for you

Intel's Core Duo http://en.wikipedia.org/wiki/Intel_Core E4500, 2.2 GHz
or
AMD's Athlon http://en.wikipedia.org/wiki/Athlon X2 Core Duo 4450e, 2.3 GHz

Ok first of all the E4500 is a Intel Core 2 duo, not a core duo.
2nd, theres no such thing as a AMD core duo.
3rd, if you dont know that 45w is less than 65w, then you probably shouldnt be building a computer.

Well the first two statements here are correct but the numbers he listed are the TDP which means the cooling required to cool the chips. The power consumption is a different area.

I looked for some charts but they had none. Try googling it. Mayeb you will have better results.

Yeah actually I agree with wisecrack. Get the 4450e with a 740G. Should be more than enough for your needs.

And if you don't know that the TDP is not a good reflection of power usage and that AMD and Intel use different methods to calculate, you should refrain from answering.

Thanks for the answers so far.

Sorry, that I confused you a bit with the incorrect designations, I probably had spent already to much time googling...

To reassure Mrs.Bytch:
No, I wasn't intending to build the computer myself, although I do know what a Watt is and that 45 is less than 65.
I just learned from googling, that knowing the TDP isn't enough...

This would be a good solution.

The key difference is not going to be the CPU for power consumption, but the motherboard.
The AMD Chipsets are built using a much smaller process so they are far more efficient.

The on-board graphics of AMD chips is also superior in most regards.

The computing power either chip should be fine for normal office tasks.

@ OP, what video card are you going to be running?

Only reason why I asked, is because when I got my E4400, and used my dad's old 7300GT, it was getting a decent power consumption. It all changed when I got my 8800GTS (G80), which tagged 50-60w on idle. Even underclocking my GPU, I only got 10w lower. :lol: . o O( I think my P4 3.0ghz was even doing better on power efficiency @ idle with a 6800GS Agp)

on board of course. Almost no reason to run a separate video card on a office computer, unless you work with programs that really require it, but I think this computer will be to surf the net and run office programs, right?

 

[Grimmy]

I was just asking, since you really didn't mention what MB. Not all MB has on board video.

The on board video should do just fine then, for regular office stuff.

Just a little tip... the 45W AMD X2 series actually consumes more power at stock voltage than the 65W Intel E7200...

Plus, IIRC, the Intel 4 series chipsets are 65nm, so should be more energy efficient than the 3s.
