Yes, or add a few GPUs ($/£/Eoros) and striking a balance becomes rather more necessary than you would desire; they don’t have 2 extra power connectors for nothing!


Good analogy. This is why very fast planes fly very high, or dont go too far!

With CPUs it is a matter of looking at the initial outlay, the power consumption and the performance. This is why it is better to buy a good system and a fast CPU and fun it for a year or so, than buy an average system.
The fast system gets more credit per £/$/Euro overall; it flies higher.
It is also why I have to turn my average systems off, unless they have a useful GPU!

Ok, now that we are talking electricity...
been a long time since I did the math on power consumption,
I dont remember the formulas but how's this.
300 watts of power draw.
I'm assuming that's per hour?
so 3 plus hours for a kilowatt?
If so at 7 cents a kilowatt, that's 8 KW a day, 240 a month
is 16 dollars and change...
my 4 computers (1 a laptop, 1 a slow single core emachine
micro) so I'll guess 700 watts an hour is about 35 dollars a month.
1/3 my electric bill. that's crazy. I have the compact flourescents in most of the lights, except the tract lighting
which have a slightly dif base (that's 300 watts an hour on
them). I use LED lights (2 watts an hour) instead during
the day, but we cook every night and have a fridge and freezer going so I guess all things considered we aren't doing
badly (not complaining about price btw, just usage in gen).
When i go back to work looking at solar, I would like to offset
my electrical consumption, partially anyway. Oh we bought a
50" plasma... I had no idea they were 500plus watts. almost
never watch TV though, just use it for movies.
Sorry for off topic...

You should. In this way you know what you really contribute in terms of financial effort. Even if you use already amortized older desktops say to 0$ value, energy is the vital fluid that make crunching possible. And that never stops, only piles up over time. The longer you crunch higher is your contribution.
I know what it costs me. I made all the detailed calculations as we have complicated energy prices in Switzerland, with day and night prices, week end prices, official holiday prices etc. We have also separate calculations between the energy production itself, the transmission costs , various taxes etc. The bill has become so complex that you need some time to read and understand what you really pay. But there is no competition yet. I am sure in a competing system I would have lower prices due to my high volume consumed. The only advantage I see is that my carbon footprint is very low. Swiss electrical energy is both from Hydro origin and Nuclear origin (about 50/50), both extremely low on carbon emission.
At the moment my energy costs are 416 US$/month or 5'000 US$/year. This with an average 240 watts power consumption per device.

Crunch, Crunch, Crunch, Crunch.........

Can you please take the questioning of the credit/point ratio to a different/own thread!

thanks

From Help:
and

skgiven, very easy to compute.
You say that you produce 58'000 credits at GPU Grid in one day. These correspond to 409'500 WCG points. This is due to the ratio of 7 that is applied between Boinc credits and WCG points.
If you want to know what that is in TFLOPS is easy.
One day has 86'400 seconds. So you produce:

409'500 / 86'400 = 4.7 WCG Points per second.

1 TFLOP = 8 WCG -----> 8/4.7 = 1.7 TFLOPS This is your crunching power.
Never mix TFLOP and TFLOPS. Just for the record in one day you have crunched a total number of:
409'500/8 = 51'187 TFLOP or rounded 51 PFLOP. That is exactely 51'187'000'000'000'0000 floating point operations.
Not bad for a little GPU.
