GPU Guidance

Post by JRobinsonJr »

I may have missed this already, but if not would really appreciate some guidance. It's time to buy a new GPU anyway and I would just as soon get one that will serve the Folding project as well. What characteristics of a GPU are important? What is the priority?
  • Memory
    Memory Bandwidth
    GPU Clock Speed
    Number of Streaming Processors
Thanks!

Newest generation of streaming cores beats previous generation.
Number of streaming Processors.
GPU Clock Speed.
Memory is already fast enough and wide enough on all models and so has little impact. Some people even under-clock the memory to run higher core clocks.

For FAH, memory and bandwidth are relatively insignificant. Shader count and speed are of prime importance.

Both ATI/AMD and NVidia are supported although there's currently a driver problem with Maxwell and NV seems to be concentrating all their resources on improving the frame rate of popular games. It's not clear how quickly this might be resolved.
