    Thanks for your reply :)
    When I said cpu:6 I meant how appears in fah control panel, so with cpu:6 fah uses half of the processing power of my 3930 k. 6 from 12 threads, and the ppd is 19-20 K. With cpu: 10 I have 36k. 1 thread is used by the gpu for fah, so 1 thread it's not used, but can be if I buy another gpu.
    So if in the future I buy a 1060 I don't have to link it by sli bridge to my 1070, I just have to put that card in a pci express slot and when entering fah control the card will be recognised?

    It's great to hear that jumping from 6 CPUs to 10 CPUs gives a nice boost in PPD!

    Yep, you pop-in the GTX 1060, hook it up to the PSU (if it needs to) and F@H should pick it up automatically without issues when you go to add another GPU Slot :) However, if you have angered the F@H gods, can always help you out :p

    I have read elsewhere (unofficial) that FahCore_a7 is new for CPU and aims to make CPU folding more balanced PPD-wise. If that is indeed the case, we can expect official news soon :)

    Maybe this core is more efficient than a4 and it's faster, I think the ppd are in relation to the science being made.

    Me too>From 36k to 56K . more than 50% :)

    i was gonna stop the cpu folding but this may have changed my mind

    I wonder if it uses the AVX/AVX2 for getting better performance. Here are my stats:
    CPU:6 when from 25K to 83K with TPF of 41 seconds. I would have to say, it's great news for my system :)

    Maybe, I don't have AVX/AVX2 on 3930k , and your ppd increased by more than 200%, that's incredible. It seems that the newer cpu's have a greater benefit. But I'm happy with 56k.So a 6950x maybe can get well over 200k.

    You are right, now I want to fold more on the cpu, than before ;) It was a very big difference between cpu's and gpu's ppd wise. So I understand the sofware behind the core is very important, to get the best of our cpu's.

    I do like the PPD boost as long as it is related to the science (not an easy thing). My best guess is that they might have an initial trial, see what PPD range is there and may optimize the PPD to reflect the actual science being done. They tend to do it when a new FahCore is released so let's see what happens.

    This is another thread from another team discussing FahCore_a7 (http://www.overclock.net/t/1613533/new-cpu-core-ax7-not-sure-if-this-is-news). Seems to me that it is very new so hopefully, can get more details, would be a nice Christmas gift for my CPU [​IMG]

    You are right, the ppd must reflect the actual science, anyway if a7 is more efficient, the ppd also have to increase.

    So, this new core uses, besides other, the avx, which it seems to have a big impact in the simulation of proteins. In the description of the 11920 project they say are using an old 9752 a4 core project. I remember this project. It was one with the biggest ppd , except bigadv projects. If I remember correctly with cpu:10 at @4,4 gave me in the range of 50k. Now with cpu:10 this "new" project 55-56k. So it's a bit faster than a4, but I think the biggest gain is the use of avx, which I don't have at this cpu :( .

    Thanks for the thread, maybe somebody with avx and 12, 16 or 20 threads can say how much ppd they have. Anyway, my next cpu will be with at least 8/16, and must have avx. I'm wondering if Zen has avx?:3eyes:

    I have to correct myself:bang:, it seems I have avx, but I don't have avx 2, that's why I don't see a big gain in ppd?

    I did remember that PG was looking into AVX support but that was a while back (few years). However, the good news is that "stuff" is happening in the background (https://foldingforum.org/viewtopic.php?f=72&t=28119) so until they officially announce what changes are in FahCore_a7 and/or FahCore_a8, your guess is as good as mine. Given that I got it while not using any flags and there wasn't any blog post about misconfigured server(s), I would say that this is intention so a public announcement could be soonish :)

    I did compare our CPUs (http://ark.intel.com/compare/88195,63697) and have a few thoughts:
    1) There is 3 Generation's "performance gap". I have briefly read articles that performance jump between each generation is 5% to 10% but not sure how that relates to F@H performance.
    2) i7-6700K has SSE4.1 and AVX2 instructions which yours don't. Not sure if the PPD increase is from SSE4.1 and/or AVX2 instructions.
    3) While you use DDR3 and I use DDR4, the difference between RAM timings can't really account for that difference. May be a percentage or two but not more than that unless there's some dramatic changes that I am unaware of.

    AMD Zen I do believe might have AVX support natively but AVX2 isn't nativly supported... Until it is released, it might be unclear:
    Source (http://www.anandtech.com/show/10591...t-2-extracting-instructionlevel-parallelism/2)
    Source (http://www.anandtech.com/show/10591...t-2-extracting-instructionlevel-parallelism/4)

    I guess 2017 might be an awesome year for CPU folding [​IMG]

    Interesting information regarding zen but we have almost no clue regarding how zen will do with fah.I hope this new architecture will be a big step for amd to close the distance between them and intel. If on the gpu side we have tons of information regarding the performance, the cpu segment is lacking ppd numbers. That's why is important to inform others about the cpu ppd we have. The cpu folding is important too...
    For now I am still happy with my 3930k regardless of lacking SSE4.1 and AVX2. And the fact that intel gains in ipc are very small 5-10% per generation, and the amount of money they charge, in the near future, I don't plan to upgrade. But Zen is interesting and like you said 2017 could be a very exciting year for cpu's...
    So, there is an a8 core also?

    Project 11920, cpu:12 - 67k tpf 0:47. In the near future I will try at @4,4.

    While I haven't gotten the knowledge to decode the flags of the compiler, I did come across this:
    SIMD: avx_256
    Now I am unsure if this is AVX or AVX2 as the Wikipedia isn't very clear about that and the few threads that I have read about, aren't very clear about it :/

    Moreover, this FahCore is under a month old which is great:
    Date: Sep 21 2016

    Hopefully, they can give us an early Christmas gift by announcing an AVX and/or AVX2 FahCore along with a new FahClient (currently it is undergoing open Public Beta).

    According to the F@H thread and the project information (http://fah-web.stanford.edu/cgi-bin/fahproject.overusingIPswillbebanned?p=11900), yep but that could be an internal build or a typo. My best guess is that FahCore_a7 is AVX while FahCore_a8 is AVX2. However, it is just a guess :)

    I'm only a couple of WU's in on my RX480 and it's getting 346174 PPD and my cpu is getting 10170 PPD

    fairly big step up from my R9 285 on 0x21 core

    @ PantherX
    I've never seen an 0xa7 or a8 core WU always with the 0xa4

    That's very good. That's more than 3x what I used to get with 270x. And it's half of my 1070.
    You will have a great contribution to fah with your RX480 :)

    I don't know why, but I know that for several days I didn't received an a7 core project, maybe because I fold just 1-2 projects per day with my cpu, and the chances to get one are slim. Regarding a8 I never received this kind of WU.
