Are There Any Retailers in Aus Selling 'T' Series 11th Gen Intel CPUs, E.g., i5-11400t or i5-11500t

  CPU will dynamically use power required for current processing (Ex: my 5600x idles at 20 W but goes up to 75 W at 100% all cores load).
  You can use HWMonitor to see current CPU & GPU power usage.

  I have seen some old "T" CPUs (6500T etc) at e-waste recyclers. Mostly taken from industrial applications.
  Ex (these are used PCs):
  Dell OptiPlex 3050 Micro i3 6100T 3.2GHz 8GB 128GB SSD W10P PC for $259
  Dell OptiPlex 3070 USDT i5 9500T 2.2GHz 16GB 256GB SSD W10P PC for $729
  May be you can get an "U" part laptop for your task if you are that much worried about power,

  TDP is not total power draw. TDP stands for thermal design point, which is about only about thermals and tells us nothing about actual power consumption. Intel can advertise a Core x processor with 65 watt TDP but that only tells you that the CPU will (maybe, at a certain clock speed) dump roughly 65 watts of heat into it's environment… but that doesn't tell you how much it's drawing from the wall socket. And it's not even accurate either because that 65w tdp that is advertised isn't a solid number, but actually a range or a blanket rating for convenience.

  Intel T series chips are just nerfed / undervolted and underclocked versions of their non-T siblings. You can do roughly the same thing by undervolting in Intel XTU, if you want cut back on power usage. Guide

  Why not buy a laptop / nuc or an AMD system CPU? the 5600X can be easily down clocked to 3GHZ etc and voltage lowered for the desired result

  also the difference between 15w and 65w running 24/7 with everything else the same over 1 year is @ 30c per KW is $131.4

  $131.4 per year or 37c a day running 24/7

    $131.4 is running at 100% 24/7. In reality, it might cost a dollar or two more per year.

  as the PC will be on 24/7

  Honestly, the power usage of a PC isn't much. Honestly, I have 2 computers running 24/7 (did have 3) and I haven't noticed much of a difference in the amount of power being used or even the bill.

  My entire office is currently drawing under 500 watts and that includes:
  - 2 x PCs
  - 2 x 42 LCD TVs
  - 3 x 27" monitors
  - Small Network Switch
  - Small other things like some charges, power packs for laptop and speakers.

  For a 24/7 period that is under 8kwh which is like under $2 for an entire 24 hour period. It is really bugger all to run a PC 24/7.

  I had a T-series CPU in my Alienware Alpha; simply due to the minimally sized cooling in the tiny case.

  a lower TDP it will be cheaper to run. Is that true?

  No, not true. Just means it'll draw less maximum power. Makes no difference at idle.

  if my base load is around 10w does it matter

  It doesn't matter. If it's idling most of the time then it'll make no difference.

  Is this for an existing mobo/PC or are you building? There are certainly good alternatives for less power draw like NUCs, laptops, even RasPi depending on your use cases (e.g. a Plex server)

  To give you an understanding of running a PC 24/7. I took one out of my server cupboard which I have a smart energy monitor on. When I compared two months recently. It was about 20kwh difference from 1 month when I was running it to an entire month without it. 20kwh @ $0.30 per kwh is about $6 per month.

  I wouldn't bother trying to get computer components that will be cheaper to run, all for under $10 for a 24/7 is pretty good. Like that is 3 cups of coffee, it isn't much to run a PC 24/7.
