RPS benchmarks
Just for interest. Post your bench!!!
i7 3630QM at 3.2 GHz "28 watts with core temp software" with HT on (can't turn HT off on this laptop) AVX FFT length 200K, Pass1=640, Pass2=320 on both instances 1.158 ms k=5 n=3801694 1.164 ms k=5 n=3812730

Paul's 4770K at 3.9 GHz, HT off.
0.975 ms k=5 n=4100030 AVX FFT length 224K 0.977 ms k=5 n=4200010 AVX FFT length 224K 1.050 ms k=5 n=4300000 AVX FFT length 240K 1.042 ms k=5 n=4400024 AVX FFT length 240K Edit: Paul, correct me if I am wrong. Thank you. Last fiddled with by pinhodecarlos on 20140104 at 12:06

benchmarks only useful with all cores busy and then divide it by number of cores you run for total throughput.
At the oldie Xeon machines here it takes pretty long for 1 test, yet each box i can run 8 cores meanwhile total box consumption 170 watt. Built those machines a few years ago for total peanuts, like 200 euro each. Chip inside L5420 has SSSE so not AVX. All those new i7's, they have fast AVX, yet only 4 real cores. Where is the big progress in crunching there? the L5420 or something i run here at 2.5Ghz, they were produced http://ark.intel.com/nl/products/339...z1333MHzFSB So januari 2008. If we calculate then derived truth from Moore's Law each 18 months doubling in speed, then now januari 2014 we should have a new chip available that's: 6 years == 72 months => 72 / 18 = 4 doublings => 2^4 = 16 times faster than the chips i got. Only gpu's seem to speed up, though also goes slower now than a few years ago for progress there.

Note that this is with all 4 cores loaded and with 2400MHz RAM.

I only have completiontime for all iterations.
LLR graphical shows iteration times CLLR64 is considerable faster however. It is textmode. Just prints result in lresults.txt Machine was only actively used at 8 cores by CLLR64 when it printed result of the prime find here. Which is pretty much average time of the n's around it that it tested. 69*2^26499391 is prime! Time : 5925.793 seconds. So if i use calculator that makes iteration time 5925793 /2649939 = 2.2362 ms Really great for 2.5Ghz @ 8 cores Xeon from 2008.

Anyone here with some benches on AMD Opteron 6300 series? Does AVX works as on the Intel processors?

I was in doubt because it is much cheaper to buy an AMD server with 4 processors than one from Intel. Thank you.
