BOINC LHC@Home GPU vs CPU

[BotDamian]

Hello there,

I hope that im not the only one doing the LHC project.

I don't really care about the points etc but i think it's good to compare the hardware right?

 

I have a AMD 7900X with 95W PBO and a 3060ti. LHC doesn't support Nvidia GPUs and I wonder how much faster a AMD GPU is than my AMD 7900X and if there is any use for CPUs. By that I mean, are CPUs doing their own tasks that GPUs can't do, for example assembling the whole GPU data into one or something. Because if a normal GPU like RX6800 does 10x more points than my CPU and the CPU has no specialized tasks then I think CPUs make no sense, performance/watt wise.

 

I would be very thankful if someone with an AMD GPU could run the LHC project on a GPU and share the results. My CPU does 13.5k credits at 95W, idk how valid that score is because im also playing games so the tasks are paused.

 

Thanks for your time reading it :)

But there appears to be only two people active neither of whom I can find with a similar username in the forums.

 

I don't have access to any current AMD GPUs so I unfortunately can't help. I doubt my Radeon Pro W4100 in my Windoze Daily Driver would provide a meaningful comparison

 

In general most GPU-specific BOINC tasks are different Work Units or packaged differently that CPU tasks. CPUs have a much more versatile instruction set and so are more useful for more complex calculations that can't be modeled on a GPU. But yes, in general CPUs are vastly out-performed by GPUs and are much more efficient.

 

My CPUs run Mapping Cancer Markers and Open Pandemics on World Community Grid and my GPUs run Open Pandemics when there are available Work Units and Einstein@Home where there are none.

Ok understood, I mean, if there are WU/tasks that a GPU can't do provided by lets say LHC@home then it doesn't really matter how efficient the GPU is because a GPU can't finish the WU. My CPU is locked at 95W  and this with German prices is enough, 1KW/h is 40cents in Germany, the Government is crazy here.
