I changed GPU from GTX580 SLI to GTX780Ti SLI few month ago.
But Credit/day of BOINCstats.com seems decreased.

I want information about GPU performance of GTX580 and GTX780Ti
as GPGPU of SETI@home.

AstroPulse (which gives better credit/h) is down so anyone's RAC is down
I now have "Recent average credit 3,851" and usually when AstroPulse is working my RAC is ~8500

BilBg, thanks.
But I still doubt performance of GTX780Ti.

I have two computers which run SETI.
http://setiathome.berkeley.edu/hosts_user.php?userid=858
ID: 4862228 (Core2Duo E8500, GTX580)'s RAC is about 16,000.
ID: 7328558 (Core i7-4790K, GTX780Ti SLI)'s RAC is about 30,000.

More distinction should be expected from SPEC, I think.

Do you use app_config.xml to run 2 tasks per GPU?

<app_config>

   <app>
      <name>setiathome_v7</name>
      <gpu_versions>
         <gpu_usage>0.5</gpu_usage>
         <cpu_usage>0.04</cpu_usage>
      </gpu_versions>
   </app>

   <app>
      <name>astropulse_v7</name>
      <gpu_versions>
         <gpu_usage>0.5</gpu_usage>
         <cpu_usage>0.5</cpu_usage>
      </gpu_versions>
   </app>

</app_config>

P.S.
If you want people which use GPUs like yours to give info on their speed first hand - post in Number Crunching
Or you can click the red-x square under your first post and ask a moderator to move this thread to Number Crunching

I can't comment on the gtx580, but my pair of GTX780 are doing about 45000....

My three GTX780 are doing ~ 70000+ (on MB only for now).

... ...

I'd too advise of doing 2 (maybe 3) at a time.

Thank you for your advices.
I quickly appended "app_config.xml" to run 2 tasks per GPU.

But why 2 or 3 tasks are recommended for the performance?
BOINC's default setting is 1 task per GPU.

There is lots if tweaking info on the 780 cards there.

One at at time works for all (If any).

Sending work, receiving answers, seding new .. They all have a wait time (latency). Both the CPU and GPU can do something valuable when waiting for the other.

I'll remark that I have fairly good experience with both GF110 (GTX 570/580) and GK110 (GTX 780/Ti) and the latter will definitely perform better in S@h than the former (even GTX 780 vs GTX 580) by a reasonably good margin. It's just not easy to see this in terms of RAC, especially with task generation and validation being quite spotty over the past several months.

I wrote "ap_cmdline_win_x86_SSE2_OpenCL_NV.txt" for AstroPulse as follows
referring to The GTX750(Ti) Thread and "v0.43a_ReadMe_AstroPulse_OpenCL_NV.txt".

GTX780Ti
-use_sleep -unroll 16 -oclFFT_plan 256 16 256 -ffa_block 16384 -ffa_block_fetch 8192 -tune 1 64 8 1 -tune 2 64 8 1 -hp

GTX580
-use_sleep -unroll 12 -oclFFT_plan 256 16 256 -ffa_block 12288 -ffa_block_fetch 6144 -tune 1 64 8 1 -tune 2 64 8 1 -hp

It's just not easy to see this in terms of RAC, especially with task generation and validation being quite spotty over the past several months.

I will wait for a long time. Thank you.
