Title: AMD 7340 vs AMD 6320 vs AMD 6310 Post by: Redi on March 24, 2013, 08:08:27 PM Hi,
I will be building small server in the near future and since I started mining BTC for fun I'm thinking of using AMD APU for the job (since CPU load during GPU mining is near 0%). So I can choose between these 3 motherboards (I want to use the integrated GPU, external one is not an option) >> https://ubuntuone.com/7lTU8AmMTSypVNsxHasYaf So, how much will the 6320 and 7340 give? Can the 7340 give 1,5x/2x more or will the speed be approximately the same? P.S. The CPU speed is irrelevant to me, for my scenario even the E-350 will be enough. Hope this post will not end unnoticed :) Title: Re: AMD 7340 vs AMD 6320 vs AMD 6310 Post by: Redi on March 24, 2013, 09:03:28 PM I even found some OpenCL benchmark results. But are they credible?
AMD 7340 OpneCL Benchmark (http://clbenchmark.com/device-info.jsp?config=14779300) AMD 6320 OpneCL Benchmark (http://clbenchmark.com/device-info.jsp?config=12051345) AMD 6310 OpneCL Benchmark (http://clbenchmark.com/device-info.jsp?config=12030192) And which one is similar to mining? ??? Title: Re: AMD 7340 vs AMD 6320 vs AMD 6310 Post by: Crystallas on March 24, 2013, 10:28:02 PM Unfortunately there is only a ~5 MHash/s difference between the 3. Absolute best case scenario(with current software), you might get 14MHash/s out of the 7340, and worst case scenario, a 4.5 MHash/s from the 6310. So of course, this would be money better spent elsewhere.

There should be only small difference between the two, right? I still have to find reasonable data about Linux support on these two (Would like to use the new Debian Stable on it...).
Electrical consumption does not bother me since it will be powered by solar panels anyway :) Title: Re: AMD 7340 vs AMD 6320 vs AMD 6310 Post by: Crystallas on March 24, 2013, 11:21:51 PM Yes, unfortunately, the 7x and 6x means little. Its the x3xx that is performance limited. At this phase, you're scrubbing every last bit to squeeze out another 100-500 KHash/s. I would suggest pricing 5570 options, if that is possible. x5xx is a nicer leap, and the price difference is still mild, as well as the TDP remaining fairly low at sub-40 watt.
