Some computer specs are reported (on projects websites) as
[Coprocessors: [2] NVIDIA GeForce GTX 970
What I assume it means rig has 2 cards installed, at least one is 970.
This computer has 2 cards and running times either ~1000s or ~3000s. I guess 1000s might be for GTX 970 and 3000s for a weaker card, as times on e@h are consistent and my 1060 takes ~1000s for a task.
Thus listed card is probably the fastest one or random, as it always shows GTX 970 for this computer.
I've checked manually only a handful of entries for my articles to make sure I check computers with only one card installed.
How did you solve this problem for your statistic?
[Coprocessors: [2] NVIDIA GeForce GTX 970 -> means that there are 2 GTX 970s installed
Mixing different cards from the same company is rare but they should appear as
[coprocs][BOINC|7.6.33][CUDA|GeForce GTX 780|1|3072MB|37892][CUDA|GeForce GTX 770|1|2048MB|35286][/coprocs]
in the host file.
Though that data from Einstein does look suspicious. I also ran the code a separate time only allowing for machines with one GPU and obtained close to the same results. But I may go back to limiting the results to machines with only one GPU.
I always remove machines that have multiple flags for CUDA (Nvidia), multiple flags for CAL (AMD), or both flags.
Thanks, informative.
It seems some projects report in different ways, at least on the website, as I haven't checked host files. Amicable and e@h it seems lists only name for 1 card, unlike asteroids (see @parejan comment). As tasks at e@h take the same time to finish (+/- 5%) I would be surprised if they are both 970s, as this computer takes either ~1000s or ~3000s to solve a task. Unless one card would be severely starved of some resources and the other not.
Thanks for pointing this out. Definitely something to watch.
Though I do wish that e@h (and yoyo) would use the
standardcurrent version of the website. It would make the analysis work a lot easier.I guess they are really 2 GTX970's in one system.
Have a look at these systems:
http://www.asteroidsathome.net/boinc/show_host_detail.php?hostid=26048
http://www.asteroidsathome.net/boinc/show_host_detail.php?hostid=100737
http://www.asteroidsathome.net/boinc/show_host_detail.php?hostid=240829
where you have different combinations of GPUs.
Nevertheless and interesting aspect to understand.

Interesting. All these projects are on different versions of BOINC software, which probablity doesn't help here to obtain the same level of information.
