You get best efficiency at full load but lower CPU clock rate.
The advantage to CPU's in general will be project selection. It could take years for that GPU's efficiency to make up the difference in buying a bunch of ARM devices. Ras.Pi's are a bit more costly than cheap phones. Throw the up front costs into your over all expense consideration and you will find things look a little different. These phones were purchased for $10 each brand new. However, I have not done comparisons with other chips or GPU's at other projects as I will run the devices regardless. The numbers I compared a long time ago was at Enigma or WCG (can't remember now). So even 2 phones at 8 watts out performs that older laptop CPU. The cell phone pulls less than 4 watts last I checked. the rest of the system will cause it to draw even more. So, if you are basing it off TDP power draw. It will produce about half the points of a Genuine Intel(R) CPU T1400 1.73GHz CPU (2 processor cores). An LG Optimus Fuel has one ARMv7 Processor rev 3 (v7l)(2 processor cores) 1.2GHz. I have several cell phones with various ARM chips. Another thing is that TDP numbers don't really = real power draw numbers so it would be best to ask in the forums of the various projects to get what users are actually reporting. I would also recommend going to some projects and get real numbers rather than guestimated numbers. They all have different scoring and so a RasPi2 will score different at Einstein than it would at Collatz. The big problem here though is that you have to look at all the projects you intend to support. Could you recommend a BOINC-specialized build (possibly including GPU) for that? Or is such a low-power setup not viable? I calculated that the maximum Wattage my build should have is 100-150W. Also the main idea is to have an independent system for BOINC projects.

Also running a system only for certain times a day is not what I am looking for since I want a system that can run continuously so that the credits will add up over I am not currently using my big pc (it's not even at my house right now) but an older macbook which can hardly handle running BOINC in the background. To get started I could certainly use my gaming rig and I might as well do that but with a 900W power supply it is extremely wasteful (and I would pay ~2.2k € a year). Thanks for the quick Bayliss Thanks for the info on the CPU differences, I wasn't aware of Thanks for those numbers! The RAC/Watt is very interesting and with that and Les Bayliss' info a low power CPU or GPU setup seems to be much better than any Raspi cluster. What CPU / GPU combination do you have? Perhaps don't run it 7x24? There are several solutions to achieve auto shut down. Maybe start up a project on the gaming rig to get a feel for the projects and what works. I run a large AMD HD7990 which draws 480W but generates 340000 RAC daily so 708 RAC/Watt. So 100RAC/Watt but note these are not GPU apps.Ī lower power GPU such as the GTX 750 Ti adds 60W to say a 140W PC - and i would expect it to generate 23000 RAC/day, so 23000/200= 460 RAC/Watt. However you are quite limited on the applications which you can run, see Les's posts to find them.Īt Raspberry Pi2 generate about 400 RAC/day for 4 Watts.
GPU computing will normally be more energy-efficient than any CPU. Good to think about this, especially if electricity is expensive. What are your thoughts on this? Is a raspi setup viable? I am not gonna do a GPU build since that would draw too much power. The main selling point here is the ultra low energy consumption (~4W) and the relatively powerful quad-core cpu.Īnother idea is to have a nice setup with maybe 2 high-end CPUs and have that running at all times.Īgain, the main scope of the project is to have a machine running maybe even years and get long-term service from it, not quick credits for a couple months. My first idea was having up to 10 raspberry pis (V.2 model B) running at all times. So the main concern for my project is to make it energy efficient. I have a 3-year old gaming rig that still packs a punch but running it 24/7 long time is prohibitive for me due to electricity cost. I am thinking about SETI, Rosetta and CPU Projects mainly. To start off I have been thinking about building a dedicated machine for BIONC for a long time now. I found an old thread on the topic but thought it would be worth discussing this again and with a few special ideas I've had. This is my first post here as I am not yet participating in any BIONC project and I hope this is the right place to ask.
