Is there any list of flops cpus can perform?

[Arkyo00]

If no, how can we calculate double-precision performance for a CPU? Especially nowadays cpus are multi-threaded, the formula really confused me.

I have done researched on the internet , and the most convincing formula is

sockets * (cores per socket) * (number of clock cycles per second) * (number of floating point operations per cycle).

E.g. for the i7-7700 , the GFLOPs will be 1 socket * 4 physical cores * 4 cycle/s(all 4 cores enabled) * 16(flopc)

Seems right to me.

Are you just doing this out of curiosity?

Umm... I am a silly guy , I want to get all FLOPS of previous generations of GeForce cards , build a model and train-fit it in TensorFlow to predict RTX series' performance

clock cycles (per second) is your frequency, it's not 4 it's 4.2 million if you run at 4.2Ghz like the 7700k does.
Also hyperthreading will mess you up,since it's 8 threads.

It is 4 because GHz => GFLOPS , this has no doubt.
Also, when cpu turbo boosts, the frequency varies at how many cores are active.

Anyways , I have found http://cads.iiap.res.in/tools/flopsCalc

That website doesn't seem to do anything other than perform the multiplication steps you listed in your first post. Which I suppose is convenient, but ultimately something that would be trivial to do yourself in a spreadsheet.

I think the part that could prove difficult in some cases would be finding the operations/cycle value for a given CPU (although the list on the Wikipedia FLOPS pages does seem to include most popular ones).

@TerryLaze yeah that threw me off too until I noticed the calculation was in GFLOPS.
