Hello, some inquiries about cuda and graphics card

[north861025]

Hello, which is more important in tyflow, cuda graphics card and cpu?
  When rendering with vray, you can query the scores of different CPUs on the V-Ray 5 Benchmark website to calculate the cost and performance of the CPU.
  Is there similar comparative data for cuda graphics card in tyflow
  If there are two graphics cards, 2060s 8g and 3090 24g, the price of the latter is 600% of the former, can the performance of the latter be improved by 300%~600% in tyflow project, Or how to calculate the performance improvement
  

[tyFlow]

I don't have or collect any specific usage/benchmark info, but in my own experience the number of compute cores on a GPU scales pretty well with the performance of tyFlow's GPU-accelerated components. It's not necessarily a perfectly linear correspondence, since there are many other factors at play...but considering how many pieces of software nowadays rely on GPU-acceleration for various things, it's never a bad idea to spring for a GPU that's as powerful as possible, if you can afford it.

And keep in mind not all of tyFlow is GPU accelerated. The cloth/bind solvers are, as well as many of the new terrain components, but there are many areas of tyFlow that rely on CPU multi-threading speed and have no GPU acceleration...so if you're sacrificing CPU speed in order to afford a better GPU, that might not give you the performance boost you expect. Try to raise the performance of your entire system as a whole rather than running an insane GPU with a slow CPU or vice versa.
