  Hello
  I want to get a system with the following specifications.
  processor: AMD RYZEN 9 3950x - 16 core, 32 thread, 64MB Cache
  RAM : 32 GB DDR4
  Question 1: Are these specifications suitable for Lumerical performance?
  Question 2: Is AMD processor better for Lumerical simulation or Intel processor?
  Question 3: Does having a graphics card affect computing speed and performance? If the answer is positive, Nvidia is better or AMD graphic card

  See this article on how hardware affects Lumerical (FDTD) simulations. The faster the Memory Bandwidth the better. For AMD RYZEN 9 3950, memory bandwidth: [memory speed in MHz]*[# memory channels]*[8 bytes]/1000 = 3200x2x8/1000 = 51.2 GB/s. See this post for details on how to obtain a simulation's optimum resource configuration on a computer.
