Topic 196851

wonder if any one has the numbers on the gpu cards
with 336 cores vs 1000 + cores X 2 sli 16x pci slots?

then use them on a grid vs in one system or pc with more than 2 gpu cards..

the reason i ask is that is if i have one gpu card at 1000 plus gpu cores vs 2 cards at 2000 plus gpu cores

is that better than two pc with one card each of 1000+
cores?

thanks for the input.

It depends on what you think is best, are you looking at power efficiency, initial build cost or maximizing the output in terms of tasks completed?

For power efficiency going with one system and multiple GPUs would be cheaper as you don't have to power an extra system but that would sacrifice the possible gain in tasks completed on the second machines CPU. There might also be some problems in keeping multiple GPUs running at their max performance if the system isn't powerful enough to feed them. Putting multiple GPUs into one system also demands that one take some care in how the system is cooled as GPUs do produce quite a bit of heat a having a few next to each other might spell trouble if one ain't careful.
Building a system that can support multiple GPUs requires more expensive components compared to building two machines that only support on GPU each. So depending on what one picks either one could probably be cheaper.

the reason I ask is that in

the reason I ask is that in my office I spend 2000 watt heater..

now if I can build a gpu grid that will heat my office..

I will heat my office with the gpu grid and transfer the compute power
to the project while enjoy the heat from the gpu grid.

and not just waist the electric heat on heat with no compute cycles on it.

thanks for the input.

My PC setup MSI-970A-G46 AMD FX-8350 8 core OC'd 4.45GHz 16GB ram PC3-10700 Geforce GTX 650Ti Windows 7 x64 PSU is 750 watts. I have Antec Liquid CPU Kuhler 920 Intel/AMD Universal cooler and the temp runs around 38c to 41c. When I close my door it takes a bit but gets up to 40c to 41c and my room is quite warm. I am only running this desktop in bedroom. I run CPU and GPU most of the time "I do however stop Boinc from time to time to play a game for afew hours" Depending on how big the place is you are trying to heat will determine how many pc's you would need to run. I would also suggest to run CPU and GPU on all of them as that would get the most work done, most available credit and heating for your office. Just taking a guess "without knowing your office size" I would guess 3 to 5 desktops would put out enough heat but it would also help to run fans to move the warm air around which would make 3 desktops feel like heat wise of maybe 4 desktops. Many users use computers running Boinc to heat with and has been said it's cheaper to do so as long as you are in a cooler place but when it gets summer time it really get warm... lol then it cost more to cool the pc's.

Ok lastly... Start with 1 computer and see what the office temp is. Then add another pc and again check office temp. all while your 2k heater is off so you can feel what is going on as well as seeing the temp. of the office. After you have added the 2nd pc you should be able to tell if you are going to need 3, 4, or even 5 pc's. Best of luck and post when you have done it and let us know how it is working out for you.

Its just a matter of money.

Its just a matter of money. I bought one EBAY HP core duo special for $100 delivered and added a $90 [200 core] ZOTAC GTS 450 CUDA card which produced about about 12,000 credits per day AND drew 640 watts at the plug. I did not know HP sold space heater/PC combos! A couple of these babies and you would be toasted out of the office.

So I replaced the transformer for another $80 and now draw 140 watts. If you did that your would freeze. If cost is an object I would not use GPUs at all because they do not produce much heat for the cost. Instead, just run normal BONIC stuff on any and all dumpster PCs. I have been given half a dozen older units that would do BOINC stuff essentially for free, while at the same time heating the entire neighborhood.

I am going the other way. I THINK I can produce 50,000 credits per day on a single machine that will draw 200 watts. But the rig will cost about $1,500 and won't heat a broom closet.
