Electrical Costs
Posted: Sun Sep 07, 2008 5:40 pm
I would like to start an informational thread about general FAH electrical costs. This thread is NOT to be used for complaints, but to share information for decision making purposes. In light of some current grumblings of electricity prices and client efficiency on this board, I have put together some of my observations. Like any other type of donation, you have a choice as to how much you wish to donate. I wish to stress, that choice is yours.
My FAH consists of the three rigs below. In Delaware, U.S., I pay $0.145 per Kilowatt hour. In the summer time with the air conditioner running, folding accounts for 35% of my bill or approximately $50 per month. Note: In the winter time yes it has literally heated part of my apartment, but I don't have any numbers/bills laying around to support how much it may have dropped my heating bill. Though I can say for fact it did make it decrease, I just don't know by how much, and if the lower gas bill offset the price of the higher electric bill.
I don't own a Kill-a-Watt or similar device, though I really wish I did. These ballpark figures do give you a fairly close idea though.
HP Notebook DV6408nr with Turion TL-56, 2 Gigs of RAM, and an integrated 6150 Graphics chipset, running Ubuntu 8.04 and the Linux SMP Client
-power usage ~45 watts with the screen turned off.
-600 to 1200 ppd depending on work unit
-so about 13 to 27 points per watt efficiency
-costs me $4.70 a month
PS3 (with newer 65nm Cell B.E.)
-power usage ~135watts ( compared to ~200 watts for the original 90nm)
-900ppd
-so about 6.6 points per watt efficiency ( about 4.5 points per watt efficiency for 90nm)
-costs me $14.09 a month ( 90nm would cost me about $20.88)
Custom built Desktop: AMD X2 3800+ (Manchester Core) Overclocked to 2.5Ghz, 2 Gigs of RAM, with a Radeon 4850.
This computer runs XP SP3 32 bit running only the AMD GPU2 Client.
-power usage ~300 watts
-1500 to 3500 ppd depending on work unit
- so about 5 to 12 points per watt efficiency
-costs me $31.32 a month
Let's decode this quick, by putting this in terms that are easier to grasp taking power efficiency into account, but not the time it would take to complete the work. Because obviously the GPU client is the main bread winner when it comes to speed, or ppd. Let's say, "How many points will $20 buy me?"
For $20 the-
-Notebook will run for 127.68 days and return 76,608 to 153,216 points.
-PS3 will run for 42.56 days and return 38,305 points. ( 90nm will run for 28.7 Days and return 25,856 points)
-Desktop will run for 19.15 days and return 28,725 to 67,025 points.
Clearly the Notebook win efficiency wise. Not that I had any thoughts that it wouldn't. The PS3 client is starting to show a little age in the points department, but is not as bad on the pocket book as the monstrous GPU Client. On a side note, the Nvidia GPU client has even higher ppd, sometimes over double that of the current ATI GPU Client. I don't have much experience with the Nvidia Client, so I don't know any power numbers, but I do know for the most part as of this day, September 7th, The Nvidia Client is more efficient than the ATI one.

I also wish I had some uniprocessor info too, but I can only work with what I have.
Edit: As always, YMMV.
