Hello,

I'm wondering which CPU would be best for running multiple (4+) simba RS scripts and doing some work at the same time (Chrome, CS6, word…). I was looking especially at these:

AMD FX-6100 (six core, 95W TDP)
AMD A10-5700k (quad core, 65W TDP)
AMD A10-5800k (quad core, 100W TDP)

Power consumption is quite a bit important for me, so I wonder if it would be better to pick the A10-5700k with the lowest TDP or pick one of the others and play with it a bit (undervolt, underclock..). Do you guys have any experience with these? Thanks for your answers :)

You have a motherboard already and really need an AMD CPU? Intel offers more performance with a lower TDP most of the times. But it is more expensive, but in the end it might be worth it because of the electrical costs.

I wouldn't really undervolt/underclock a CPU so if the TDP is really important go with the AMD A10 5700. Can handle 4 bots and some other tasks. It should perform similar to an intel i3 3220 which has a TDP of 55W. So there is a 10W difference and they are about the same price.

If your concerned about power consumption focus on the power supply not the cpu (with silver/gold power rating). I'm pretty sure the listed wattage on the cpu is the peak power usage not the actually power consumption. If your going with AMD I suggest AMD FX-8150 Zambezi 3.6GHz Socket AM3+ 125W or whatever fits your budget.

Well I don't have motherboard yet, I was looking for AMDs rather because of my small budget. If you say Intel processors really beat AMDs that much I will look for Intel. Thanks for your suggestion! :)

I was curious so I looked it up:

More typically, TDP stands for Thermal Design Power. It means that whatever you are using to cool the electronic component should be capable of dissipating this much heat, in order to keep the part from failing/malfunctioning/melting into a pile of goo when under the "maximum perceived load" (usually a reasonable estimate of the maximum amount of power the part will require).

It does not mean that if your TDP=100W, then your CPU is using 100W; only that for whatever amount of power the CPU IS using, it requires the dissipation of 100W in order to function properly at that performance level.

Like I said your power supply will change your power consumption way more then the CPU. I've only managed to get my AMD 8 core to ~80% going ALL out. So even if your running 4 smarts etc. doesn't mean you'll be using 100watts of the full cpu because its not going "all out." So if your under-rating what your using it'll use more power because its using max load on the cpu creating more heat. Does that make sense to you?

Edit:
When I upgraded I didn't change my 580w power supply that I used with my Intel Q8300 that I now use for my AMD 8core. I spent a good amount of money on my power supple to make sure it wouldn't fail me.

Oh, its basic ignorance then, sorry for that :/ Thought that the TDP is the main factor that determinates power usage. How can I know how many Watts power supply is ideal for me then? And also is there any advantage having more W power supply than I actually need?

Newegg.com has a good power supply calculator. I suggest checking the top PSUs, I spent I think $150 on mine, totally worth it. I'm on my 3rd cpu because of it. Your CPU may change over the years by the power has remained the same since the beginning of power usage at ~110 volts sadly. You only need 600W+ PSUs when you get to 2+ High end video cards or TONS of extras on your computer. 500-600w is max you'll need for standard computer builds.
