hi everyone. i am trying to understand the hardware associated with CFD software like ANSYS. i just want to know which is better for serious computational power - more number of slow cores or less number of faster cores. i will be a research scholar soon, hence i want to know as much as i can about the hardware. any advice related to CFD hardware will be appreciated. i have to buy a system which can perform very well the simulations and computations of fluid dynamics. is mac pro a good choice?

it is a balancing act and it starts with budget.
of which I believe your question has been discussed several times in this forum.

hardware usage ranges from the single, multicore workstation to hundreds of clustered servers. One may or may not be surprised what an Intel Xeon based 16 core (no hyperthreads here) workstation with 64GB of RAM could calculate.

also, as far as I know, OSX is not supported.

I'd say a Mac is not a good choice for anything... except emptying your wallet.
