Good that the new one installed without problem and runs cool.
Was a bit surprised at the great variability in Einstein runtimes for the same cards and the sometimes smallish difference between 970s, 980s 1070s and 1080s.
At first thought it was sometimes due to configurations with multiple cards slowing GPU processing down a bit but I've seen some slower times with single cards. And no, not that slow that it is likely 2 or more tasks run concurrently.
Then thought perhaps the speed of the CPU can have an affect because there is a portion of CPU processing after the semicoherent output stage is completed by GPU.
Then realised that various models/brands of the same card type can run at different speeds or boost differently. This could also perhaps be affected by cooling solution used on card, case cooling, room temperature.
Then there's potential CPU starvation issues, some may get a GPU speed up by leaving a CPU core free in addition to the CPU core automatically allocated to GPU tasks.
In some projects the higher model cards don't get to more fully utilise their performance potential unless they run multiple concurrent tasks but Dataman's experience with his 1080 and 2 concurrent means possibly not on Einstein.
So don't know, perhaps it could be a number of those issues. Strange though, I'd expect a much greater difference considering the differences in hardware specification. In other words, would have thought a 1080 or even a 1070 should absolutely blitz my 970 but doesn't seem to be the case on Einstein.
Do know it's hard to research many different configurations now in Einstein as the website has been horridly vandalised so only shows 50 hosts.
Noticed the task list is almost unusable now as well as no task numbers are shown and also no listing of different task types for those who crunch more than 1 type or do Einstein CPU as well.
What is it with these projects completely mucking up their websites lately? Is it some misguided and poorly implemented attempt to make the websites "mobile friendly" or what? Next they'll be hiding wingman details as well on quorum tasks like the horror, the horror of WCG. Bah, humbug.
Running multiple cards can be a pain sometimes and is something I resolved not to do again. I too would choose a single higher model GPU if I was getting stuck right into GPU crunching again. However this all makes me wonder if a couple of lower models such as 1050 Ti or 1060 would give better bang per watt on Einstein than a single top model. Because the electricity bills keep coming in after the cost of GPUs is forgotten.
