How about if we calculate electricity cost per 1000xRAC, and convert it to $'s.

T7200 XP32, intake 68W, RAC abt 1100 (KWSN 2.4), 10 eurocents/kWh, 1.632 kWh/day, 1.484 Wh / cobblestone, 14 eurocents per 1000 cobbles, 23.7 (us)cents per 1000 cobbles

So, the T7200 produces 1000 cobbles with $0.27.

Gee wiz, there must be something wrong with my logic, or is there?

Continuing:
A64 3500+, 135W, RAC abt 400 (SSE2), 3.24 kWh/day, 8.1 Wh / cobble, 12.9 (us)cents per cobble

A64 produces 1000 cobbles with $12.9.

Such a difference, hope someone proves my calculations totally ascrewedf, or something.

There's an order of magnitude, or decimal point, slip somewhere.

Roughly: twice the power, one third the production, makes 6x the cost. You have it at 60x the cost.

I believe the error is in the calculation for the A64,
8.1 Wh/cobble = 8100 Wh/1000 cobbles = 8.1 Kwh/1000 cobbles = 8.1 * 10 EuCents
Which by my calculations = 81 EuCents, or about $1.56 or so?

[Edited out redundant '.' - also changed amount in $$, not really sure what exchange rate is, based on other amounts...]

Let me see if I can figure out how much it cost me to run my seti 24/7 to see if I understand all this electricty stuff.
My rig uses about 300 watts times 24 hours equals 7200 or 7.2kwh times 30 days in a month equals 216kwh times my electric company rate of .049 cents for each kwh equals 10.58$USD. I am I right or wrong?

I did agree with your first assumption, to begin with. Now i just rechecked it, and found no error. What what what, might it be correct? Bear in mind that the T7200 draws half of what the AMD64 3500 does. In addition it provides a healthy computing power over the AMD. Combine these two effects, and whoops, is it possible that my calculations were close to reality.

I'm well surprised.

And to Paul,

The idea is to compare cost/credit, so all the factors would be built in.
Trying to exclude everything possible BUT the cost of electricity relative to standard income. So unifying interational cost per 1000 cobblestones is what I was trying to achieve.

I really do imagine some interesting figures, once you all start to calculate and publish them.

Greetings, Olli

Surely, Dave, you are quite right about the decimal point, it must be $1.29/1000 cobbles. It couldn't be more than that.

Thanks, more sharp eyes to comment my idea.
